The John Deere 700PF Cutting Platforms has the fully integrated header control system. The automatic-control, programmable header functions provide optimum performance and operator ease and comfort.
This system provides automatic control of:
Up to 7.6 m (25 ft), the 700PF Platform is equipped with three AHC sensors that follow the contour to ensure an even stubble height and minimize the risk of damaging the header in uneven terrain.
The 730PF 9.15-m (30-ft) to 740PF 12.2-m (40-ft) headers come with four AHC sensors. One additional sensor provides the highest cutting quality and maximum field performance by large header sizes. AHC sensors are evenly positioned close to the knife in the table and therefore moved together with the knife. This position allows for best reactivity in rolling terrain.
The long cutting table is equipped with a rigid cutterbar. The conveyor belts feed short material effectively from the cutterbar to the auger. At the same time, the generous 100-cm (39.4-in.) distance from the cutterbar to the auger ensures efficient feeding. The conveyor belts speed can be infinitely adjusted to guarantee excellent feeding capability. The active material feeding technology of the 700PF ensures that the crop is fed smoothly into the combine for effective threshing. This reduces load peaks and wear on the drives and boosts reliability.
The heavy-duty driveline for the auger and cutterbar on the left-hand side of the cutting platform is designed for the biggest throughput and best efficiency. The epicyclical knife drive gearbox is driven by a driveshaft, the intake auger is driven by a strong chain, and a 1200-Nm (885-lb-ft) slip clutch to protect the auger and driveline in case of crop plugging.

Single driveshaft from left side from the feederhouse
The single drive shaft on the left-hand side of the platform keeps platform hookup easy and fast. The platform knife and auger are driven from a single drive shaft, which connects to a splined feederhouse drive shaft. The single drive shaft is standard configuration from 6.7 m (22 ft) up to 12.2 m (40 ft).
Single drive and synchronized dual knife drive
From 6.7 m (22 ft) up to 9.1 m (30 ft) there is a single-side knife drive which is located on the left-hand side and is driven by a driveshaft. On 10.7-m (35-ft) and 12.2-m (40-ft) models there is a dual-side knife drive which is also based a driveshaft and allows the synchronized operation of two cutting knives.
On all models, the drive system is protected by a heavy-duty slip clutch which is linked to the main drive pulley.
All hydraulic and electric drives of the header are fed by the advanced multicoupler which delivers electricity and hydraulics to drive the header functions.
A storage bracket holds the coupler when the platform is not in use and provides clean and reliable hydraulic and electrical connections.
All 700PF Series Cutting Platforms feature an extra-large, 760-mm (29.9-in.) auger tube with deep auger flights (167 mm [6.57 in.]) to handle large amounts of crop. This design provides a very big area under the auger to aggressively feed large volumes of crop material. The inner diameter of the 760-mm (29.9-in.) auger is 425 mm (16.7 in.). Because of the increased auger diameter, the length of the auger fingers has increased from 150 mm (5.9 in.) to 200 mm (7.9 in.).
All augers are equipped with retractable auger fingers over the full width of the auger. The outside fingers are in a spiral order for smooth and quiet auger running. In the center part, the amount of installed fingers increased by 30 percent. Auger fingers are designed for quick replacement and mounted with a finger retainer. Auger finger retainers prevent broken fingers from being moved into the combine, minimizing the potential damage caused by rocks or other obstructions.
Split auger to keep high performance over full cutting widths
Up to 9.15 m (30 ft), the auger will stay as one single auger like on the 700X. For the 10.7-m (35-ft) and 12.2-m (40-ft) platforms, a central auger bearing will be used to allow harvesting in high-yielding conditions with maximum feeding capacity.
The adjustable intake auger from the 7.6 m (22 ft) for maximum versatility is equipped with a hydraulic lift system to guarantee a quick adaption when going in rape seed. This is done manually with a hand pump on the cutting platform to set the auger up for harvesting rapeseed for smoothest feeding and an optimal match for the high performance of the John Deere combines. To change the auger position, no tools are required. The drive chain tension does not need to be adjusted.
The 700PF Series Cutting Platform augers come standard with full-width retractable fingers. That means there is always one additional finger between each wrap of auger flights which helps to move tough or green crop faster and creates a more even feeding. The high-capacity auger is easy to maintain and has great uptime. Each intake finger can be reached easily and comfortably by special-designed service doors on the intake auger to keep uptime high and the harvest efficient. The intake auger position is adjustable for maximum versatility.
The retractable fingers are 16 mm (0.63 in.) in diameter with a reach of 200 mm (7.9 in.). Fingers have a breakaway groove and are secured with a retainer preventing them to enter the combine. Replacement is fast and easy.
The backsheet extension is available on all 700PF Cutting Platforms; the backsheet extension increases the rear wall of cutting platforms to reduce losses in tall crops (for example, rapeseed).
The backsheet extension is factory installed. This metal sheet is on top of the 700PF frame and helps to reduce back wall header losses in tall crops. Especially in rapeseed, the backsheet extension has an advantage as it keeps the light rape cereals in the header and increases daily outcome. The bended top edge prevents grain from exiting the rear wall.
The pick-up reel gently delivers crop from the cutterbar to the platform auger. An adjustment of the reel height matches all crops and conditions. Due to the full integration of the reel, operators have the availability to save the reel position with help of the reel resume function out of the driver seat. The 700PF will be equipped with polymer reel tines.
The single piece pick-up reel from 6.7 m (22 ft) up to 10.7 m (35 ft) as well as the split reel for 12.2 m (40 ft) gently deliver crop from the cutterbar to the auger. An infinite adjustment of the reel height matches all crops and conditions. Integrated anti-collision software helps avoid damage to the reel and cutterbar. All functionalities are the same as the current 600R and 700X Headers. The 740PF will be delivered with a split reel which is equipped with a central bearing system to prepare an even and consistent material flow for the large header size.
The reel was split to guarantee more stiffness and grant all functionalities, even at 12.2 m (40 ft). The central bearing is very narrow to allow a great view on the table.
Table and reel resume to position
Linked to the reel is the reel resume to position function. This function saves preferred cutting height and reel position with an easy click on one of the 1/2/3 buttons on the hydro handle. With that functionality, operators can save three different positions to optimize the operation. For example, button 3 can be programmed for down crop operation, button 2 for standing crop, and button 1 for the headland. This feature grants a lot more convenience to the operator by having the exact pre-selected settings of the reel by pushing just one button and return to that position automatically when resume button is selected.
Automatic reel speed
Automatic reel speed provides automatic control of speed for the reel, delivering the most convenient operating comfort.
Operating speed is a ratio of machine ground speed to reel or belt speed. System operates with any header equipped with the appropriate reel sensors. Reel speed can be manually fine-tuned from the operator’s seat.
With the 700PF reel, the operator can manually adjust the reel tine angle. Three different tine angles support a better crop pick up when it comes to different crops and conditions. Depending on how the reel tines are set, the operator can be more or less aggressive to pick up down crop from the ground. The adjustment is to be done at the side of the header.
Hydrostatic reel drive
The hydraulic power for the reel drive motors is supplied by the combine.
Hydrostatic reel drive and extended height hydraulic reel lift enable the operator to adjust the reel height and vary the reel speed on the go to match field and crop conditions.
Reel drive motor uses positive gear drive instead of chains that wear and require adjusting. Reel speed is infinite within its speed range of the combine.
To preselect crop and dirt directly after the knife, the conveyor belts on the extended cutting table act like a stone dam which is directly integrated into the complete 700PF table structure.
Everything is designed for quick crop-to-crop conversion. John Deere developed a click-on system for side knives and crop dividers with easy access.
Jump from one field into the other without using any tools to set the platform in the best position. This gives the highest flexibility during the entire harvest season to always have the platform in best configuration to meet high performance and efficiency in each condition. A quick clutch and clamp design is 100 percent tool free and allows easy mounting/dismounting for just one person. This is also supported by the low weight of the side knife since there is no hydraulic or electric drive.
The quick mechanical-driven side knives are in base on all 700PF Headers.
