General Rotary Tiller Operation
ALWAYS shut the engine off when removing a
stone or anything that becomes entangled in the
tines.
All large stones or rocks should be removed from
the area before you begin tilling.
Tilling can be done with or without the outer tine
assemblies. You can till 32V2" wide with the outer
tines and 17" wide with only the inner tines.
Use rear wheel weights when tilling.
Maximum tilling depth is approximately 10"
depending on the type of soil. This CANNOT be
accomplished in one pass. Maximum tilling depth
may be only
2 V 2 " on extremely hard soil on the
first pass.
The more passes you make with the tiller over the
same area, the deeper you can till and the finer
you pulverize the soil. Change directions as often
as you can to level out the ground and to prevent
furrows.
When tilling, the tiller will push the tractor and the
transmission on the tractor will hold the tractor
back.
For easy lifting of the rotary tiller from the ground,
shut off the power by disengaging the PTC handle
and continue to drive the tractor forward. The
tines will climb out of the hole when you pull the
lift lever handle back.
