Rear Wheel Track
Rear wheels are assembled and shipped in narrow track.
Wheel track can be changed to wide track by reversing
wheels on hubs.
Jack and block rear of tractor with wheels off ground and
remove wheel lug nuts. Remove wheel, reverse and
remount on axle hub with valve stems inward. Replace
and tighten lug nuts.
On tractor with traction tread tires, to maintain proper
direction of rotation, reassemble wheels on opposite
sides of tractor with valve stems inward.
Narrow Wheel Tread Setting (shown)
23 X 10.50 X 12 = 32 1/2
Wide Tread
23 X 10.50 X 12 = 35 1/2

Center Rockshaft Flotation
The center rockshaft flotation chain allows
for reduction of mower attachment weight on
height gauge rollers. Thus it floats easier and
independently of tractor hydraulic system.
Hydraulic lift lever may be held in "DOWN" position until
end of stroke and then retained in "HOLD" position.
Mower deck will still float with chain adjusted for minimum
weight on rollers.
CAUTION
Always grasp chain handle firmly when adjusting chain
tension. Tension on chain could cause injury to hands.
DO NOT grasp chain.
Adjust chain tension by placing chain third link into notch
on back of tractor frame when mower is on tractor.
Decrease tension for more weight on mower height
gauge rollers and increase tension for less weight.
Release tension before mower is removed.

LEANING AND
Never store unit in an enclosed area where fuel fumes
may reach flame, sparks, pilot lights or an ignited
object. Drain fuel outdoors away from any ignition
source. Use only approved fuel container.
Inspect tractor for visible signs of wear, breakage or
damage. Order any parts required and make necessary
repairs to avoid delays when beginning to use again.
Clean tractor thoroughly. Touch up all unpainted areas to
OT1200
avoid rust.
IMPORTANT: NEVER spray unit with water or store unit
outdoors to aid in prevention of rust or corrosion.
Water can seep into sealed bearings, which are sealed
against dirt and debris only, causing reduced component
life.
Engine
When storing tractor for extended periods, we
recommend stabilization of fuel with a gum and varnish
preventing anti-oxidant stabilizer or empty fuel tank and
carburetor.
Battery
Disconnect the positive (+) terminal for storage over
30 days.
Cover unit and store it in a dry moisture free area.
