Heavy-Duty Frame
The frame of the SR 800 Series wheel rakes is built with heavy-duty components to ensure a long service life when running in rough field conditions and heavy use. The overhead frame can be extended out to match with any mower size and windrow width.
60” Rake Wheels
The 60” rake wheels are built from heavy-duty steel to ensure a long service life. Windguards and rubber tines ensure a smooth crop flow and uniform windrow. The rubber tines are flexible, yet tough enough to pick up long or wet crop, without incorporating an excessive amount of dirt or ash into the windrow.
Tandem Axles
Tandem axles provide improved performance in difficult field and crop conditions. The machine will float better over pivot tracks and through waterways or ditches.
Rake Wheel Angle
All of the rake wheels are angled 8.7 degrees allowing the crop to be lifted off of the ground and flow easily from wheel to wheel to create a uniform, fluffy windrow.
Windrow Formation Rake Wheel
This rake wheel is added to the farthest back position on the rake wheel arm. The purpose of this extra wheel is to kick up the final portion of the windrow and throw the crop back on top of the windrow. This will produce an even, fluffy windrow that allows air to pass through and dry the windrow consistently allowing the crop to feed evenly into a round or square baler or forage harvester.
Rake Wheel Suspension
Individually floating rake wheels are mounted on spring-suspended arms and can be adjusted on each side. This reduces soil disturbance, providing cleaner raking and resulting in higher quality hay.
Rake Wheel Ground Pressure Adjustment
This single-point, adjustable, toolless stop on the right and left sides increases or decreases the machine’s ground pressure. It also puts the operator in control to adjust the ground pressure based on crop volume and conditions to incorporate less dirt and ash into the windrow.
Manually Adjustable Configuration
The manually adjustable configuration requires 2 DA hydraulic valves from the tractor. The first hydraulic valve will extend and retract the overhead frame. The second hydraulic valve will raise and lower the rake wheels.
Hydraulically Adjustable Configuration
The optional hydraulic configuration requires 3 DA hydraulic valves. The first two hydraulic valves do the same thing as the manual configuration. The third hydraulic valve will change the rake wheel beam angle to get the desire working width and windrow width.
Electric Control Configuration
With only one hydraulic valve, users are able to fold and unfold the rake, raise and lower the rake wheels, and adjust the beam angle to get the desired working width while never having to leave the comfort of the tractor.
