125-L/s (3,55- bu/sec) peak unloading system on the T670 Combine

Extra-fast unloading system

The extra-fast unloading system provides a peak rate of 125 L/s (3,55 bu/sec) according to ISO 5687:1999 Norm. Compared to the John Deere S770 Combine's unload rate of 116,3 L/s (3,3 bu/sec), the T670 has a faster unload rate that is also reflected in time saved when unloading on the headland. The extra-fast unloading system comes as the base option on the T670 Combine. Fast unloading on the go allows the operator to concentrate more on the crop by reducing unloading time.

The higher unload rate is achieved by the grain tank cross augers, an increased discharge housing including vertical auger, larger sprockets and chain, and an overall higher speed of the unloading system.

On the headland, the operator can reduce the rate by putting the machine at mid-idle or low idle; this allows for more precision, especially when the trailer is nearly full.

Machine Sync

Unload the combine fullest combines first with Machine Sync

With John Deere Machine Sync, the combine operator can have the tractor and grain cart drive alongside the combine while unloading. Once in position, the combine operator can control the ground speed and steering of the tractor-cart combination. Additionally, the grain cart operator can see the grain tank levels of several combines and can be called to empty the fullest tank. This saves time, diesel, nerves, and minimizes soil compaction.

The T-Series Combine is designed for high capacity. The T670 has a total sieve and chaffer area of 6,3 m² (67,8 sq ft) according to ISO Norm 6689: 1997, which is the largest cleaning shoe following the John Deere X9 Combines.

• The Flat Tooth Comb (FTC) chaffer prevent short straw from falling through the grid as they are equipped with special noses.
• The returns are guided back to the cylinder and distributed evenly over the entire width of the threshing cylinder by an auger. The amount of material is recorded and then displayed in the cab via the electronic sensors. To visually inspect the content of the tailings returns, there is an inspection flap just outside the cab door.
• The completely redesigned fan delivers up to 740 m³ (26.133 cu ft) of air per minute and evenly distributes air over the entire width. The large air volume paired with the air flow and the large sieve area makes additional slope compensating features obsolete.
• One non-ventilated step plus two ventilated steps cascades the crop down by 41 cm (16,1 in.) to ensure effective pre-cleaning of chaff. Through intensive testing, John Deere has found the right balance between air pressure and air volume. The air pressure is used to separate the grain and the air volume allows for material to be carried away. This provides the perfect pre-separation effect and evenly divides the material between the front and rear part of the chaffer.
• The heavy-duty conveyor augers ensure active crop flow on slopes and under tough harvest conditions, meaning the cleaning shoe can be optimally loaded even in damp or sticky conditions.
• The total sieve and chaffer, with its considerably enlarged surface up to 6,3 m² (67,8 sq ft), offers high cleaning performance even under tough threshing conditions.

Remote adjustment of Dyna-Flo™ Plus cleaning system

El sistema de limpieza Dyna-Flo Plus viene con un sistema de ajuste eléctrico en todos los combinados T670.

El ajuste remoto de la zapata de limpieza se puede completar desde el interior de la cabina en la configuración de la pantalla o con los botones del apoyabrazos. Como solución alternativa, por ejemplo al revisar la zapata desde el exterior, también se puede ajustar la configuración en el lado izquierdo de la parte trasera de la máquina.

Los motores del ajuste remoto de la zapata de limpieza están equipados con un sensor de posición integrado. This eliminates the need for recalibration of the electric motors. Solo se debe volver a efectuar la calibración en caso de reemplazar el hardware eléctrico o elementos de la zapata de limpieza. 

Barra de refuerzo de conexión rápida

Ajuste de la barra de refuerzo de conexión rápida

La barra de refuerzo de conexión rápida se puede ajustar desde el exterior a través del atrapapiedras con una llave de 24 mm (0,95 in). Tiene dos posiciones. In the engaged position, the concave entrance features a profiled rasp bar. En la posición desconectada, la entrada del cóncavo tiene una placa de transición lisa. El ajuste se puede completar con facilidad en cuestión de minutos.

Material flow coming from the feeder house passing the booster bar is slowed down; this increases the threshing efficiency. La barra de refuerzo no influye negativamente en el caudal de cultivo o la calidad del grano. La barra de refuerzo aumenta la eficiencia de trilla en cultivos difíciles de trillar sin cerrar las placas de cubierta para permitir una máxima separación en la superficie del cóncavo.

NOTE: The booster bar is standard on the T670 Combine.

Threshing and separation concept of T-Series Combine

Functional components:

1. Cilindro de trilla grande de 660 mm (26 in) de diámetro con 10 barras desgranadoras y superficie del cóncavo más grande
2. Smooth stripper roll and enlarged overshot beater
3. Separador más grande de 800 mm (31,5 in) con criba de separación de alto rendimiento
4. Batidor trasero de 400 mm (15,7 in) con ocho alas y criba del batidor trasero
5. Diseño de sacudidor de paja de siete saltos con rejillas universales y para mezcla de maíz y mazorca (CCM) soldadas u opcionales atornilladas
6. Sectional concave with quick adjustable de-awning plates

Cilindro de trilla grande de 660 mm (26 in) con 10 barras desgranadoras y cóncavo más grande

The unique multi-drum threshing system ensures a consistent crop flow by moving crop above the rear beater without sharp bends or abrupt changes in direction. This guarantees excellent grain and straw quality and reduces power requirements.

El cilindro de trilla grande con 10 barras desgranadoras y 660 mm (26 in) de diámetro permite obtener granos de excelente calidad y una manipulación delicada de los materiales.

Combined with the enlarged wrapping angle of 124 degrees, this ensures excellent threshing efficiency and unmatched capacity even in tough separating conditions.

• Four rasp bars are in constant contact with the crop against the concave area for excellent threshing and separating
• Proporciona un área cóncava grande y permite una baja velocidad del cilindro
• Garantiza una manipulación delicada durante la trilla y la separación para reducir el daño a los granos
• El ángulo de envoltura grande del cóncavo garantiza una buena separación de los granos desde el comienzo y reduce la carga de separación en los sacudidores de paja
• Wide, 1670-mm (65,7-in.) (six-walker) channel width grants maximum throughput even in tough separating conditions

Stripper drum and overshot beater

Tambor separador

Overshot beater

The T-Series Combine threshing system uses a smooth surface stripper roller behind the threshing cylinder to gently direct the material to the overshot beater. Esto impide la retroalimentación del material en el cilindro de trilla para prevenir obstrucciones. La velocidad del rodillo separador equivale al 125 por ciento de la velocidad del cilindro de trilla.

The 500-mm (19,7-in.) overshot beater on the T-Series Combine continues the material flow process. El material se desplaza sobre la parte superior del batidor y se dirige al tambor de separación.

Se logra un caudal de cultivo suave sin ángulos duros o cambios abruptos de dirección.

El batidor de ocho alas tiene una velocidad constante. The serrated design of the wings' leading edges engages the mat of material and moves the high volumes of tough, damp straw without buildup or bunching.

Sectional concave with quick adjustable de-awning plates

Sectional concave with small-grain inserts

Beneficios de esta característica:

• High versatility and flexibility with three different concave inserts available
• Uptime ensured with fast exchange design
• Easy access from stone trap and storage position for the concave inserts

Extra-large separator and dynamic tangential grate

The 800-mm (31,5-in.) extra-large separator drum provides additional separation capacity on the T-Series Combine. Debido al diseño abierto, el tambor no es más pesado que el diseño cerrado anterior.

The extra-large separator drum runs at two factory-installed speeds:

• 760 RPM para granos pequeños y semillas de hierba
• 380 rpm for canola, peas, and beans

There is an optional 270-rpm speed reduction kit available for corn harvest which is included in the corn package. Se puede modificar la velocidad de la correa con facilidad y rapidez al cambiar la polea de transmisión por una polea de tensión accionada por palanca.

The extra-large separator drum runs at a lower speed compared to the previous T670 design that was operated at 900/450 rpm. Si bien aparentemente las velocidades de tambor más elevadas generan una capacidad de separación más eficiente por la fuerza centrífuga más alta, se comprobó el efecto contrario. Aunque la fuerza centrífuga tiene un impacto fundamental en la capacidad de separación, las velocidades del tambor del separador que son demasiado elevadas generan un tiempo de exposición bajo en la criba del separador de alto rendimiento. This is shown in the following graph.

Comparación de velocidades del separador

Comparación de velocidades del separador

La línea roja indica el delta de rendimiento a un nivel de pérdida de un uno por ciento entre las diferentes velocidades del separador.

The dynamic tangential grate (new beginning in model year 2019) features a completely updated design equipped with a full wire profile as described below.

Dynamic tangential grate

For model year 2019 and newer, the design was changed for fewer restrictions on crop flow and optimal separation that would not affect straw quality.

• All the transversal bars are produced with round edges for better crop flow and straw quality.
• All the wires are repositioned as close to the upper edge as possible to prevent any straw accumulation, therefore improving separation capacity.
• The wires are implemented on the complete area and replace finger rakes for larger opening areas (+10 percent opening area versus model year 2016 tangential grate).

Batidor trasero y criba del batidor trasero

Batidor trasero

The 400-mm (15,7-in.) rear beater on the T-Series Combine continues the material flow process. El batidor dirige el material hacia los sacudidores de paja. The beater is driven directly from the extra-large separator drum and is operated at two speeds.

• 900 RPM para granos pequeños y semillas de hierba
• 450 RPM para colza, maíz, frijoles y guisantes

Hay una criba de separación montada debajo del batidor trasero. La criba se puede ajustar con una manija del lado derecho.

The rear separation grate features 14 percent more open area in the separator grid and a fully rounded profile on the wires and cross bars. This creates a better separation effect thanks to a faster, unobstructed crop flow over the grid with a thinner layer of material to boost the separation of kernels trapped in straw.

Hay dos posiciones disponibles:

• Posición ancha recomendada para colza, maíz, guisantes, frijoles u otros cultivos delicado
• Posición angosta para granos pequeños o semillas de hierba

Inside the T-Series threshing and separation system is an eight-winged, rear beater drum that separates the remaining grain out of the straw mat. The rear beater grate provides additional active separation area.

Concepto del sacudidor de paja

Diseño de sacudidor de siete saltos

The T-Series Combine has a seven-step straw walker concept. Compared to the previous T-Series, the model year 2017 and newer straw walker is extended by 80 mm (3,15 in.), which results in a slightly increased overall straw walker area (+ 0,1 m² [1,08 sq ft]). El concepto del bajo nivel de RPM y alto nivel de carrera de los sacudidores genera un lanzamiento eficiente para nivelar hasta los mantos más grandes de paja y abrir los canales para que los granos sueltos caigan a través de ellos. Esto da lugar a la capacidad de separación de granos más eficiente. El sacudidor de paja está disponible con rejillas universales y de CCM soldadas o atornilladas para ofrecer la mejor reconfiguración y la capacidad de readaptar la máquina para todo tipo de cultivos y condiciones.

El sacudidor de paja está equipado con un canal cerrado en la parte trasera, que garantiza la captura del grano y se alimenta de forma pareja en la bandeja de retorno del sacudidor que se encuentra debajo de la sección delantera de los sacudidores. Los divisores de secciones en la bandeja de retorno ayudan a mantener una distribución pareja del material en el zarandón delantero del sistema de limpieza, incluso en pendientes.

• El tiro alto proporciona un lanzamiento eficiente para nivelar incluso los mantos de paja más grandes y abrir los canales para que los granos caigan a través de ellos.
• Se logra una máxima separación de los granos en la sección frontal debido al impacto del manto de paja al llegar a los primeros saltos del sacudidor.
• Los cuatro saltos en ángulo de poca profundidad aportan máxima eficiencia de separación.

Hay diferentes rejillas de sacudidor disponibles para todo tipo de cultivos y condiciones.

Beneficios totales del sistema de trilla y separación:

• Greater level of productivity due to the enlarged concave wrapping angle, extra-large separator drum, and the high-performance separator grate
• El concepto de trilla y separación permite lograr la mejor calidad de grano y paja
• Implementación rápida y fácil para diferentes cultivos
• Gracias al bajo consumo de energía y la excelente calidad de la paja, este combinado es la mejor opción para los productores de paja

Teoría de la operación

Versatility on a combine is increasingly important as producers must handle multiple crops, sometimes changing between crops during the day.

The threshing needs are very different from crop to crop. Coarse grains like corn or peas require a round bar profile that is less aggressive to ensure optimal grain quality. Small grains including grass seed, vegetables seeds, and durum wheat need intensive threshing and require a small-grain concave profile which provides aggressive threshing to separate the grain.

The sectional concave is made with a fixed concave associated to a removable design on the front where the threshing begins.

Producers can install three different concave profiles:

• Small-grain concave inserts
• Universal concave inserts
• Round-bar concave inserts
• Sectional concave with round-bar concave inserts

Producers can exchange the concave inserts in 15 to 20 minutes by opening the stone trap.

Concave inserts can be exchanged on the combine

A screw is available on the left side and maintains the concave inserts in the working position. When the operator loosens the screw, he can easily remove the two inserts and replace them with another set of inserts.

On the right side, the operator has the capability via a screw to install or remove the swing in/out booster bar.

The machine is delivered with small-grain inserts installed and can receive additional universal inserts as factory installed (in storage) or round-bar inserts as dealer installed.

Achieve more with less effort

With the John Deere satellite-based, hands-free AutoTrac™ steering system, every machine pass utilizes the full cutting width of your platform. This helps you save time and fuel and boost your combine performance - even at night, in dusty conditions, on hillside terrain, or after long hours of operation. The automatic steering relieves your operators and allows them to concentrate on productivity. When working with multiple machines in a field, the AutoTrac guidance lines can be shared from one machine to another so that all combines can harvest at the full cutting width. They can also be shared with the tractor or grain cart operator so the machines can drive exactly parallel to each other during unloading.

ICA increases the performance of a combine

With Interactive Combine Adjustment (ICA), you can increase the performance of your combine, minimize losses, avoid grain damage, and improve the quality of your straw. You can either optimize all parameters at the same time or focus on one.

Automatic Combine Adjust (ACA)

Standard on all models within the T Series, Automatic Combine Adjust helps you effortlessly transition between crop types. By using standard John Deere values and retrieving data on your current threshing and separating conditions, it automatically adapts your machine to optimize performance. You can then use these proposed values or modify and save them for later use.

HarvestSmart™ system – Always the right speed

The HarvestSmart system automatically adapts the speed of the combine to maximize capacity or minimize losses with the highest output. Sensors on the threshing cylinder, engine, and dedicated loss sensors control the system with the goal of minimizing losses or maximizing the throughput rate.

Extra fine cut chopper rotor and housing

The improved extra fine cut straw chopper delivers excellent chopping quality and best-in-class residue distribution of chopped material in the field with a cutting width up to 10,7 m (35 ft) and 108 knives.

The extra fine cut chopper comes standard with serrated chopper knives, which ensure superior splicing of the straw and improved straw rotting process. This chopper is highly recommended for producers with no tillage or minimum tillage operations.

La transmisión opcional de dos velocidades de la trituradora aporta flexibilidad para todo tipo de cultivos y condiciones.

Ajuste de los apoyabrazos

The extra fine cut chopper comes standard with a remote adjustable tailboard.

The remote adjustable vane tailboard can be adjusted from the cab conveniently via armrest control buttons (button A). The in-cab adjustment includes a unique tailboard position swap button (button B); by pressing the button on the armrest, the tailboard vanes automatically swap from left to right stored position and vice versa.

Carcasa con estructura de piso falso

The extra fine cut chopper housing follows the contour of the rotating knifes. This false floor geometry narrows the gap between the rotating knife and the chopper housing to a 4- to 5-mm (0,16- to 0,2-in.) closing at a wrapping angle of 83 degrees. No requiere ajustes ni mantenimiento o reemplazos.

Paleta de viento

The T670 with extra fine cut chopper comes standard equipped with wind paddles, which are factory installed on two knife rows. Las paletas de viento están montadas con bujes para soportar los impactos de objetos extraños. Equipped with wind paddles, the extra fine cut chopper can spread the chopped straw evenly up to 10,7 m (35 ft). Wind paddles are more effective than active radial spreaders, which are normally hydraulically driven.

Contrachuchillas

Ajuste de contracuchillas

The extra fine cut chopper comes standard with a counter knife row, which is infinitely adjustable with two large leavers on each side. Para sujetar la posición, solo se debe ajustar un perno a cada lado.

Barra de agarre

Ajuste de barra de agarre

The extra fine cut chopper features a redesigned grouser bar, which is infinitely adjustable with a slide bar. Para reducir la longitud del material triturado en condiciones de paja verde, se debe accionar la barra de agarre. En condiciones secas, mejora la unión de la paja. Para reducir el consumo de combustible, se recomienda retirar la barra de agarre al triturar otros cultivos como maíz, colza, frijoles, guisantes y girasol. 

Ajuste de ángulo de la plataforma trasera

Ajuste de paletas de la plataforma trasera

El ángulo de la plataforma trasera se puede ajustar sin herramientas en tres posiciones con una palanca a cada lado.

Además del ajuste de tres puntos de la plataforma trasera, se puede configurar el ángulo de las paletas en cuatro posiciones adicionales para garantizar que el ancho de distribución de residuos coincida con todas las plataformas de corte hasta 10,7 m (35 ft).

The extra fine cut chopper comes standard with a 10-vane electrical tailboard design.

Chapa para hileras

Placa deflectora de hileras

Embrague de la trituradora de paja

Una sola palanca opera la placa deflectora de hileras. Se opera del lado derecho para guiar la paja hacia la trituradora o hacia el suelo para el hilerado.

La trituradora de paja es propulsada directamente desde la caja de engranajes principal del motor y se conecta directamente con la transmisión del separador. Una correa de uso intenso transmite potencia motriz a la trituradora. Se usa un embrague confiable para conectar y desconectar el rotor de la trituradora.
