POWER RAKE OPERATION
WARNING! Failure to obey the following procedures could result in death or serious
injury.
•
Never lift this product above (a) the operator’s eye level or (b) to a height
where visibility is obstructed, whichever is lower.
1.
Never raise the Power Rake more than a few inches off the ground when traveling from job
site to job site.
2.
For the roller to operate effectively, it must rotate in the opposite direction of the prime mover
wheels [see figure below]. Roller direction is controlled by prime mover hydraulic controls or
PTO shaft. PTO shaft rotation cannot be reversed and results in roller rotation shown in the
lower illustration.
3.
Normal operating ground speed is between 3 and 5 mph. In heavy rock, reduce speed to 1 to
3 mph.
4.
For hydraulic drive, normal operating rpm of the roller is approximately 170. If operating in
heavy rock, reduce speed as appropriate. For PTO drive the drum rpm is constant at 211 at
540 PTO rpm.
5.
Operating depth will determine how much dirt is carried ahead of the roller. Ideal depth will
vary from skimming the surface to about 3” deep.
6.
When making the first windrow, the level of dirt may be halfway up the deflector. After moving
the windrow two or three times, the level of dirt may be to the top of the deflector. Try to
prevent material from flowing over the top of the deflector. Volume and density of material will
dictate how many times a windrow can be moved.
7.
The following are common operating applications:

Pulverizing topsoil

*See your prime mover’s manual for whether or not your loader has hydraulic float capabilities. For
models with 4-bar linkages, remove the clevis pin (part # 96) to float. (pins may be stored in the
middle position holes of the back plate ribs.) For PTO drive models connect the upper link at the
slotted mast hole.
8.
When adjusting the gap between the roller and deflector; a wider opening will allow more dirt
and rock to pass through. For finer raking, reduce the gap.
9.
Tires: check the air pressure of your tires before each use. Maintain recommended tire
pressure to maintain a consistent, even grade.
