Remove Mower Deck
Tractor mower deck must be removed from before installing
tiller. See your tractor operator’s manual or mower deck
manual for removal instructions.
Ballasting Requirements
All tractors require front wheel weights to be installed when
using this tiller.
Follow these recommendations to help improve traction:
•
Install tire chains on turf tires or install bar tires on the
tractor.
•
Install rear wheel weights.
Ballast weights can be purchased from your Authorized
Service Center. See your tractor operator’s manual for

Always pick up rocks, branches, and other objects that
might damage tiller.
Tilling Tips
Install correct front and rear tractor weights. See Install
Weights and Chains in Installing the Tiller section.
Always check tines before tilling. Repair or replace loose,
bent, or broken tines.
IMPORTANT: Avoid damage!
Move Implement to “LOWER” Position
DO NOT back up or make sharp turns with the tiller
in the ground.
B
Till with engine at FAST throttle, control ground speed with
appropriate transmission speed range.
A
Check tines before you till. Replace missing, bent, or
broken tines.
When you till hard ground or sod, till at a shallow depth for
the first pass. Till deeper on each pass after that.
When you till a small area, make a pass through the
middle, then circle alongside the original pass, working to
the outside. After you finish, make a few passes around the
edge to cover ridges left by turning.
Till straight ahead when possible. This will leave fewer
ridges from turning.
M97160
1. First pull implement lift lever (A) rearward slightly, then
depress and hold down button (B) to unlock lift lever locking
mechanism.
For seed bed preparation, till the soil once in the fall.
Decaying vegetation will add valuable nutrients to the soil
by spring. If the terrain is hilly or uneven, wait until spring,
or leave some untilled strips, to help reduce soil erosion.
The climate and terrain will help you decide the best time to
till.
2. Push lift lever (A) forward out of “RAISE” position
(shown), release button (B) as you continue to push lift
lever all-the-way forward until a loud metallic-click is heard,
signalling lever is in “LOCK-OUT” position, then release lift
lever—it is now locked into “LOWER” position (see next
figure).
Before Tilling
“LOCK-OUT” Position: locks tiller in “LOWER” position—for
difficult conditions, such as, heavy soils, clay, or sod. When
lift lever is “LOCKED-OUT” this means the lift spring in the
lift linkage has no effect on tiller weight.
M34147
Test soil condition by squeezing it in your hand. If soil forms
a ball, it is too wet to till. If soil does not compress easily or
falls apart, it is ready to till.
DO NOT till when soil is wet. Wet soil will stick to tines and
tine shaft. Wet soil will clump-up and dry out hard, making it
difficult to work during the growing season.
Before tilling mow tall weeds and grass to keep them from
wrapping around tines or tine shaft.
