DESCRIPTION
A full-oating rotary mower deck is designed to t all Steiner power units with the quick hitch front lift.
Three sizes match the power unit to the application. These decks are easy to attach and detach allowing
interchange with the many other front mounted attachments. The side discharge rotary mower provides
even distribution of clippings while the full-oating deck follows the contours of the terrain for an even cut with
cutting height controlled by the front caster wheels and full width rear roller. The deck can be safely serviced
and cleaned while still attached to the tractor. Convenient handles enable the deck to be lifted vertically over
90 degrees so the blades are fully exposed. Exceptional visibility and maneuvering is possible with this front
mounted design mower.

SAFETY
IMPORTANT
Safe Operation Practices for
Mowers
This cutting machine is capable of amputating
hands and feet and throwing objects. Failure to
observe the following safety instructions could
result in serious injury or death.
I GENERAL OPERATION
• Read, understand, and follow all instructions in
the manual and on the machine before starting.
• Only allow responsible adults, who are familiar
with the instructions, to operate the machine.
• Clear the area of objects such as rocks, toys,
wire, etc., which could be picked up and thrown
by the blade.
• Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters
the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely
necessary. Always look down and behind
before and while backing.
• Be aware of the mower discharge direction and
do not point it at anyone. Do not operate the
mower without the discharge chute in place
and in the locked posiiton.
• Only lift the chute for transport.
• Slow down before turning.
• Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine, and remove keys before dismounting.
• Turn off blades when not mowing.
• Stop engine before unclogging discharge
chute.
• Mow only in good light, keeping away from
holes and hidden hazards.
• Do not operate the machine while under the
inuence of alcohol or drugs.
• Watch for trafc when operating near or
crossing roadways.
• Use extra care when loading or unloading the
machine into a trailer or truck.
• Always wear safety goggles or safety glasses
with side shields when operating mower.
II SLOPE OPERATION
Slopes are a major factor related to
loss-of-control and tip-over accidents, which can
result in severe injury or death. All slopes
require extra caution. If you feel uneasy on it, do
not mow it.
DO:
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs,
etc.
• Watch for holes, ruts, or bumps. Uneven
terrain could overturn the machine. Tall grass
can hide obstacles.
• Use slow speed on slopes.
• Follow the manufacturers recommendations
for wheel weights or counterweights to improve
stability.
• Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
• Keep all movement on the slope slow and
gradual. Do not make sudden changes in
speed or direction.
• Avoid stopping or starting on a slope. If tires
lose traction, disengage the blades and
proceed slowly straight down the slope.

9
ROTARY
MOWER
SAFETY
DO NOT:
• Do not turn on slopes unless necessary, and
then, turn slowly and gradually downhill, if
possible.
• Do not mow drop-offs, ditches, or
embankments. The mower could suddenly
turn over if a wheel is over the edge of a cliff or
ditch, or if an edge caves in.
• Do not mow on wet grass. Reduced traction
could cause sliding.
• Do not try to stabilize the machine by putting
your foot on the ground.
• Do not use grass catcher on steep slopes.
III CHILDREN
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the machine and the mowing
activity. Never assume that children will remain
where you last saw them.
• Keep children out of the mowing area and
under the watchful eye of another responsible
adult.
• Be alert and turn machine off if children enter
the area.
• Before and when backing, look behind and
down for small children.
• Never carry children as passengers, even
with the blades off. They may suddenly fall off
and be seriously injured or interfere with safe
machine operation.
• Never allow children to operate the machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects that
may obscure vision.
IV SERVICE
• Use extra care in handling gasoline and other
fuels. They are ammable and the vapors are
explosive.
- Use only an approved container.
- Never remove gas cap or add fuel with
engine running. Allow engine to cool before
refueling.
- Do not smoke.
- Never add or drain fuel with machine indoors.
- Never store the machine or fuel container
inside where there is an open ame, such as
in a water heater.
• Never run the machine in a closed area.
• Keep nuts and bolts, especially blade
attachment bolts, tight and keep equipment in
good condition.
• Never tamper with safety devices. Check their
proper operation regularly.
• Keep machine free of grass, leaves, and other
debris build-up. Clean up oil or fuel spillage.
Allow machine to cool before storing.
• Stop and inspect the equipment if you strike
an object. Repair, if necessary, before re-
starting.
• Never make adjustments or repairs with the
engine running.
•Discharge chute components are subject to
wear, damage, and deterioration, which could
expose moving parts or allow objects to be
thrown. Frequently check components and
replace with manufacturer’s recommended
parts, when necessary.
•Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution
when servicing them.
• Check brake operation frequently (if equipped).
Adjust and service as required.

SERVICE
MAINTENANCE
Visual inspection for loose parts and accumulation of grass and dirt.
Clean accumulation of grass clippings from beneath deck daily for better mowing performance.
Keep blades sharp. Check the tips of the blades for wear.
In addition to daily maintenance, grease roller and all bearings.
Spindle housings must be kept full of grease. Grease spindles until grease “shows” at the relief hole
under the spindle drive pulley.
NOTE: The relief hole is under the spindle hub and is not visible. As grease enters the spindle
housing you can hear the sound of escaping air at the relief hole. Stop greasing when the sound of
escaping air ceases.
Check drive belt tension. See Drive Belt Installation on Page 16.
Check 1/4" cap screws on pulley bushings. Torque should be 95 inch pounds. Tighten these cap
screws in alternating sequence 10-12 times to assure equal torque on all cap screws.
Check blade bolts. Torque should be 75-85 ft. lbs.
In addition to daily and 25 hour maintenance, remove the drive belt and check for cracks or wear.
Rotate each spindle to check for roughness which would indicate bearing wear. Remove and
sharpen blades, clean and wash deck prior to storage. The acid in grass clippings causes premature
corrosion and rusting of mower parts.
Grease all bearings after washing.
ADJUSTMENTS
Sharpening blades
Be careful while sharpening blades that the corners of the blade do not become rounded at the tips. This
reduces the blades overlap and will cause skipping. While sharpening, it is essential to ensure the balance of
the blades is maintained to prevent vibration. Blade bolt torque should be 75-85 ft. lbs. Rotate blades after
re-installing to check for bent or bowed blades and blade alignment.

Blade alignment
When installing sharpened blades or new blades be sure the mating surfaces are clean and the retaining
washer is not bent. Check for bent blades by rotating blades until tips are near each other. (It is easier to do
this with main drive belt idler spring unhooked.)
Leveling mower deck
The front to rear leveling adjustment is provided by two slots in the linkage which supports the front of the
deck. This allows each side to be adjusted independently. Check the blade level with mower resting on a
level oor and the cutting height set at about 2-1/2" setting. Measure to the tip of the left blade at the rear,
then rotate the blade 180 degrees and measure again to the tip of the blade at the front. The cutting height
should be equal or 1/16" lower at the front. Change adjustment in the left slot as required and measure again
until proper setting is reached. Repeat procedure for blade at right end of the deck and adjust right slot.
