on the locking plate.
5. Rotate the depth adjuster clockwise to reduce
the aeration depth or counterclockwise to
increase the aeration depth.
6. Rotate the depth adjuster input shaft until the
desired depth is attained as shown on the depth
indicator decal (Figure
Note:
17 revolutions of the depth adjuster input
shaft equal approximately 6.4 mm (1/4 inch)
depth change.
Understanding the Traction
Unit Controls
Familiarize yourself with the operation of the following
traction unit controls before operating the machine:
•
PTO engagement
•
3 point hitch (raise/lower)
•
Clutch
•
Throttle
•
Gear selection
•
Parking brake
Important:
Refer to the traction unit operator's
manual for operating instructions.

Understanding the
Principles of Operation
The 3-point hitch linkage of the traction unit lifts the
machine for transport and lowers it for operation.
Power from the traction unit power take-off (PTO) is
transmitted through driveshafts, a gearbox, and drive
belts to a number of crankshafts, which drive the tine
holding arms into the turf surface.
As the traction unit travels forward with the PTO
engaged and the machine lowered, a series of holes
are created in the turf.
The penetration depth of the tines is determined by
the height of the depth control.
The distance between the aeration holes is
determined by the gear ratio (or hydrostatic traction
pedal position) of the traction unit and the number of
tines in each tine head.
Note:
Changing the engine speed does not change
hole spacing.
Practicing the Operating
Procedures
Important:
When connecting the PTO, ensure
that the machine is not lifted higher than is
necessary. Lifting the machine too high causes
the PTO driveshaft knuckles to break
The PTO can operate up to an angle of 25°, but
can never exceed a 35° angle when the machine
is at its highest position, or severe shaft damage
may occur.

Before using the machine, find a clear area and
practice operating the traction unit with the machine
installed.
Important:
If there are sprinkler heads, electrical
or communication lines, or other obstructions in
