Rear Wheel Adjustment
The rear wheel depth/stability control knob allows
adjustment for better stability and maneuverability
when the knob is turned in a clockwise rotation
Adjustments for depth are made by turning the knob
counter clockwise. This adjustment determines the
length of the cores pulled by:
Adjusting the rear wheels to a desired level to •
control the penetration of the tines to within a
fraction of an inch.
With the rear wheels in the “fully up” position,
•
maximum tine penetration is gained. Pushing
down on the machine’s handle bars puts most
of the weight of the machine on the tines. This
results in pulling the longest cores.
NOTE: Adjusting for greater stability gives greater
side-to-side control and will improve maneuverability
during aeration. (See “Operating on Slopes.”)
Adjustments for stability will shorten the length of the
cores pulled.
Turning And Maneuvering
Gradual maneuvering while aerating can be
accomplished by carefully guiding the machine.
It is recommended to adjust the engine’s speed
control to allow for a comfortable walking speed and
maintaining complete control while working in tight
spaces. Adjusting for more stability (with the rear
wheels lowered, reducing tine penetration) will make
turning easier.
When reversing direction or making sharp turns,
select the safest and most comfortable method for the
conditions you face:
Release clutch control handle, pull up rear wheel •
control handle, then pivot machine on rear wheels
to turn.
Release clutch control handle, lift handle bar and
•
pivot machine on front wheel.
WARNING!
This method is NOT recommended when
operating on slopes.
CAUTION!
NEVER cross hard objects or surfaces
(sidewalks, driveways, stepping stones,
etc.) with tines down.
WARNING!
DO NOT operate on slopes exceeding
35% grade.
WARNING!
In extreme situations (very steep slopes)
the machine may be unbalanced and
present the danger of rolling over.
