Sugarcane harvester John Deere 3520

The parallel linkage crop dividers adapt to ground unevenness for cleaner cane and reduced losses. A wide throat and 45-degree approach angle gently handle even the heaviest cane and consistently maintain the proper orientation to the ground. The benefit is that it reduces dirt content while minimizing whole stalk losses under the crop-divider toe as the row height varies.

The parallel-linkage crop dividers adapt to ground unevenness for cleaner cane and reduced losses. A wide throat and 45-degree approach angle gently handle even the heaviest cane and consistently maintain the proper orientation to the ground. The benefit is that it reduces dirt content while minimizing whole stalk losses under the crop-divider toe as the row height varies.

The large-diameter crop-divider scrolls gently lift and feed cane into the harvester throat with a much-lower approach angle, avoiding the bulldozing effect seen with other harvesters.

The hydraulic crop dividers and knockdown rollers tilt option turns a 20-minute field adjustment into an instantaneous, on-the-move operation. The toe tilted down lifts the sprawling crop, ensuring all cane is fed into the machine. In standing cane, the toe angled up reduces soil content. The knockdown roller set in the outer position facilitates feeding heavy-lodged cane.

The large adjustable knockdown rollers with deep-tooth paddles effectively feed the heaviest lodged and tangled cane into the basecutter and prevent wrapping of cane leaves and vines.

Optional dual scrolls with side knives

Optional dual scrolls with side knives are perfect for managing tangled, long, heavy, or downed cane. The standard inside scrolls rotate to lift and center the cane as it is being harvested. The outside scrolls rotate in the opposite direction to push the cane from adjacent rows away from the machine. Tangled stalks missed by the outer scrolls are cut by the side knives. This system greatly reduces the uprooting of stalks.

ntuitive steering and propulsion system improves ergonomics

Steering and propulsion system

Faster training

Inexperienced operators can be trained in less time. They will adapt easier if they have previously operated a tractor or any other piece of farm equipment with a steering wheel. The 3520’s exclusive steering and propulsion system aligns the track and wheel platforms for ease of use and reduces training times across all models.

This system uses a platform common to that of many other John Deere harvesters and tractors. Not only does the system improve comfort and ease of use, but it is fully compatible with Service ADVISOR™ and AutoTrac™ for track units.

Steering and propulsion for track units

Familiar and easy to use

On the track units, the two propulsion control levers have been replaced by a steering wheel. A propulsion and multifunction lever has taken the place of the joystick. The benefits of this system are:

Easier to operate
Train new operators faster
Easier to keep on the row
Better steering response
Easier to break open a field
Lessens operator hand fatigue

This system’s steering input device is the same as that of the John Deere 8000 and 9000 Series Track Tractors. It shares a common propulsion input device with John Deere harvesters while its propulsion and steering controller come from the same family as many other John Deere tractors.
