OPERATION
NOTICE
Do not drop tiller to the ground with the rotor turning.
Sudden high speed jolts multiply stress to the
driveline and can cause extreme damage.

Operating Techniques

Tilling Sod and Untilled Ground
For tearing up untilled sod or conditioning compacted
soils, several shallow passes will be most productive. Set
the skid shoes to one of the two most shallow positions.
A gear should be selected on the tractor for a slow travel
speed. Progressive passes can be done at progressively
faster speeds.
NOTICE
After tilling for the first half hour, check for loose
blades and re-tighten any loose hardware. Follow
the shutdown procedure and blocking method before
checking blades.
Previously Tilled Ground
To pulverize the topsoil and prepare a good seedbed, set
the skid shoes for a tilling depth equivalent to your deepest
roots. Adjust the tailgate to the fully lowered position. A
tractor gear should be selected such that the tiller does not
lug the engine.

Transportation

WARNING
A minimum 20% of tractor and equipment weight
must be on the tractor front wheels when attachments
are in transport position. Without this weight, front
tractor wheels could raise up resulting in loss of
steering. The weight may be attained with front wheel
weights, ballast in tires or front tractor weights. Weigh
the tractor and equipment. Do not estimate.
Figure 13. Tractor Stability (Typical)
1. Disengage the PTO and wait for all moving parts to come
to a complete stop. Raise the tractor 3-point arms to bring
the cutter into transport position.
2. With tiller adjusted to transport position, set upper stop
on tractor lift quadrant to prevent cutter from contacting
driveline while being raised.

Storage

WARNING
Keep children and bystanders away from storage area.
1. Disconnect cutter driveshaft and secure up off ground.
Raise cutter with 3-point hitch.
2. Place blocks under cutter side skids.
3. Lower cutter onto blocks.
4. Disconnect cutter from tractor 3-point hitch and carefully
drive tractor away from cutter.
5. Perform the Pre-Operation Check List, page 17 when
returning to use.
