Failure to comply with these instructions may result in personal injury or death.

Slope Safety

Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. This attachment makes the front of machine the heavy end.
Raising or extending (if applicable) the loader arms on a slope affects the stability of the machine. Keep the loader arms in the lowered and retracted position when on slopes..
Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope or uneven terrain requires extra caution.
Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.
Slow down and use extra care on hillsides. Ground conditions can affect the stability of the machine.
Avoid starting or stopping on a slope. If the machine loses traction, proceed slowly, straight down the slope.
Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the machine uphill.
Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.
If you feel uneasy operating the machine on a slope, do not do it.
Watch for holes, ruts, or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.
Use caution when operating on wet surfaces. Reduced traction could cause sliding.
Evaluate the area to ensure that the ground is stable enough to support the machine.
Use caution when operating the machine near the following:
- Drop-offs
- Ditches
- Embankments
- Bodies of water
The machine could suddenly roll over if a track goes over the edge or the edge caves in. Maintain a safe distance between the machine and any hazard.
Do not remove or add attachments on a slope.
Do not park the machine on a hillside or slope.

Starting the Power Rake

Start the traction unit engine.
Slowly lower the power rake to the ground.
Engage the hydraulic-control lever for auxiliary implements.
Move the traction unit forward or backward as desired.

Note: For the roller to operate effectively, rotate it in the opposite direction of the traction-unit track. The direction of the roller rotation is controlled by the traction unit hydraulic controls; refer to Figure 5 below.

Figure 5

Setting the Barrier Gap

The normal gap between the roller and the barrier for average conditions is approximately 3.2 cm (1-1/4 inches).

The barrier gap should be the same all the way across.

Set the barrier gap as follows:

To widen the barrier gap, loosen the 2 U-bolts (3/8 inch) that hold the barrier mount (Figure 6).

Note: A wider opening will allow more dirt and rock to pass through.
Figure 6
1. U bolts (3/8 inch)
To narrow the barrier gap, tighten the 2 U-bolts (3/8 inch) that hold the barrier mount (Figure 6).

Important: Ensure that the roller does not hit the barrier, as the parts could be damaged.

Using the End Plates

The end plates contain the material in front of the roller, while the clean material passes between the roller and the barrier. With the end plates mounted in the working position and the rake straight (parallel with the traction unit track), the material can be moved, filling in the low spots.

You can mount the end plates to either the front or the back of the power rake, depending on the raking direction. When you move the end plates from front to back, you must move the left one to the right side and the right one to the left side.

To move the end plate, perform the following:

Remove the 2 hairpin cotters from the end-plate pin (Figure 7).

Remove the end-plate pin from the end plate (Figure 7).
Remove the end plate (Figure 7).

Angling the Roller

You can angle the roller 20° in either direction.

For windrowing, remove the angle-locking pin (Figure 8), slide the angle mount to a new set of holes, and insert the pin.

Important: Do not drop the power rake onto the ground with the roller turning. Sudden high-speed jolts multiply the stress to the drive line, and can cause damage.

Transporting the Power Rake

Transport the power rake by using the lift points shown in Figure 9.

Important: Lifting the power rake at other points can damage the machine.

Note: Lift the machine carefully with proper lifting accessories.

Operating Tips

Operating the Power Rake

Always begin power raking at the slowest ground speed possible. Increase the ground speed if conditions permit.
Always use full throttle (maximum engine speed).
If a rock or other obstruction gets into the teeth, stop the hydraulics and drive the traction unit forward until the obstruction is dislodged.
The roller should be level with the ground. The power rake should also be level with the ground from front to back. To accomplish this, raise or lower the gauge wheels and use the traction unit tilt cylinder.
To allow the roller to penetrate deeper into the ground, loosen the handle and raise the gauge wheels. To raise the roller, lower the gauge wheels.
You can achieve further depth control by tilting the rake forward on its gauge wheels to raise the roller, or tilt the rake back to raise the gauge wheels, and allow the roller to penetrate more deeply.
Check the air pressure in each tire regularly to maintain an even and consistent grade.
To break up compacted soil, roll back the attachment plate to take the guide wheels off the ground, so that only the toothed roller is in contact with the ground. Control the ground speed to avoid stalling the toothed roller. Remove the end plates to allow material to move out of the way if you are only trying to break up the soil.
To remove loose debris, tilt the traction unit attachment plate until the guide wheels control the depth of the toothed roller. You can angle the rake at this time for windrowing debris or you can set the rake straight with both end plates installed to collect debris. You can increase the traction unit speed when you do this.
For finish grading, tilt the rake forward until the teeth of the toothed roller are barely touching the soil. You can increase the traction unit speed to collect the material from the high spots and leave it in the lower areas.
To thatch grassy areas, tilt the traction unit attachment plate forward to support the rake on the front gauge wheels and the toothed roller raised so that the teeth are just grazing the surface. The travel speed should be slow.
