Harley M6 - Pulverizing Topsoil; Parallel Arms (Float Model Only); Application Techniques; Operator Production

16 MODEL M6
By decreasing the gap between the roller and barrier, more material can be pulled along. Barrier
adjustment is shown in Figure 7 (page 18).
These plates can be mounted to the front or back of the power rake, depending on the raking
direction. When you move the endplates from front to back, you must move the left one to the
right side and the right one to the left side.
Make sure the disconnected power rake is stored on a hard, level surface. Use the endplates
mounted on attachment side of rake to ensure stability.
Operator Production
Successful operation of the power rake will come with operator experience. The rake’s performance
also depends on the type and size of the prime mover it’s mounted on.
An operator that masters the technique of adjusting the angle of attack of the roller against the
soil will also nd ideal settings under various conditions to give the desired results.
Do not drop power rake to the ground with the roller turning. Sudden
high speed jolts multiply stress to the driveline and can cause extreme
damage.
Parallel Arms (Float Model Only)
The function of the parallel arms is to allow the power rake to “oat” and follow the contour of
the ground. Lock-out pins are supplied to allow more aggressive action. However, the hydraulic
motor may stall out if too much down-pressure is applied. See Figure 7 (page 18) for pin “oat”
and “lock-out” positions.
Application Techniques
The power rake is capable of many applications. The following are some of the common
applications:
Pulverizing Topsoil
For breaking up compacted soil or conditioning hardened baseball diamonds, the attachment plate
is rolled back to take the guide wheels off the ground so only the toothed roller is in contact with
the ground. Maintain sufcient RPM to avoid stalling the toothed roller in its progress. The rake
can be straight or angled, but the endplates should not be mounted in order to allow material to
move out of the way and not slow the process.
Debris Removal
Once the surface has been loosened, the process of removing debris can begin. The prime
mover attachment plate is tilted forward until the guide wheels control the depth of the toothed
roller. The roller can be angled at this time for windrowing debris or the roller can be set straight
with both endplates installed to collect debris. Prime mover travel speed should be increased
for this process.
Finish Grading
The rake is tilted forward until the teeth of the toothed roller are barely touching the soil. Prime
mover speed can be increased for this operation, the idea being to collect material from the high
spots and leave it in the low areas.
