The table is seamlessly adjustable without any inserts or other loose parts. The conversion from small grain to rapeseed and vice versa is done in 3 minutes and requires no tools. The table can be positioned in any range without any inserts. The operation is done from the cab. The travel of the table over the full 710-mm (27,9-in.) adjustment range takes less than 30 seconds.
The 700X Header is totally integrated in the John Deere combines equal of W540 or S790. The software is reconfigurable back to 2012 and can be mounted on every machine built between 2012 and today.
The 700X has the longest extendable table (knife) in the market (1200 mm [47.2 in.]). Being able to extend the table further than competitors, John Deere can offer lower header losses in all crops among all extendable table platforms. It is important that the header moves past the reel when harvesting oil seed to reduce pre-harvest losses and increase the profit per hectare for the producer.
Intelligent software on the combine (base from model year 2014, available through CCMS on older models back to 2012) allows the operator to enter plant height and desired stubble height in the armrest display. This data, together with the entered amount of crop harvested, allows the combine to make a pre-set of the cutting table for optimized operation. This default value can be overwritten with the rocker switch on the advanced hydro handle. The advanced hydro handle has an additional rocker switch on the rear which is utilized to operate the table fore-aft function. The advanced hydro handle is available in the combine Price Pages. For existing combines, it is available through aftermarket. The table position can be stored together with reel and height position on the header resume buttons.
Everything is designed for quick crop-to-crop conversion. John Deere developed a click-on system for side knife and crop dividers with easy access.
Jump from one field into another 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 and crop type. A quick clutch and clamp design is 100 percent tool free and allows an 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.
A stainless-steel feed floor is standard equipment on the 700X Series Cutting Platforms. To connect the frame with the moveable parts, the 700X has additional stainless-steel feed plates riveted onto the frame to have a smooth crop handover to the auger. These riveted feed plates are like an extension from the header frame to the moveable parts.
The heavy-duty driveline for the auger and cutterbar on the left-hand side of the cutting platform is designed for the largest throughput and best efficiency. The epicyclical knife-drive gearbox is driven by a driveshaft, and the intake auger is driven by a strong chain and a strong slip clutch to protect the auger and driveline in case of crop plugging. The slip clutch sits directly on the auger shaft.
Epicyclical knife drive
The single-telescopic 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 telescopic drive shaft is standard configuration from 6.7 m (22 ft) up to 12.2 m (40 ft).
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 telescopic drive shaft. On 10.7-m (35-ft) and 12.2-m (40-ft) models, there is a dual-side knife drive which is also based on the telescopic drive shaft and allows the synchronized operation of two cutting knives.
On all models, the drive system is protected by a heavy-duty slip clutch. The slip clutch is directly located on the auger shaft to have no stress on the further drive components.
Storage bracket holds the coupler when the platform is not in use and provides clean and reliable hydraulic and electrical connections.
All 700X Series Cutting Platforms feature a large, 660-mm (30-in.) auger with deep auger flights to handle large amounts of crop. This design provides a very big area under the auger to aggressively feed large volumes of crop material.
A unique feature of the 700X Series Headers is the quick adjustability of the auger in two directions: depth and height. This quick adjustment allows the operator to optimize the header for any crop and condition (for example, set the auger up for harvesting rapeseed) for smoothest feeding, an optimal match for the high performance of the John Deere combines. This needs to be done manually on the left- and right-hand side of the cutting platform.
The retractable fingers are 16 mm (0.63 in.) in diameter with a reach of 125 mm (4.9 in.). Fingers have a breakaway groove and are secured with a retainer, preventing them from entering the combine. Replacement is fast and easy.
The John Deere 700X 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 700X Platform is equipped with four AHHC sensors that follow the ground contour to ensure an even stubble height and minimize the risk of damaging the header in uneven terrain.
The 730X 9.15-m (30-ft) to 740X 12.1-m (40-ft) headers come with six AHHC sensors. Two additional sensors to provide highest cutting quality and maximum field performance by large header sizes. AHHC sensors are evenly positioned close to the knife in the table and moved together with the knife. This position allows best reactivity in rolling terrain.
