INTRODUCTION section 1
Description
A full-floating rotary mower deck is designed to fit 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-floating 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.

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.
•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
influence of alcohol or drugs.
•Watch for traffic 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.
rev 11/02 2 - 2 09-254B
SAFETY section 2

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 flammable 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 flame, 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 restarting.
•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.

ATTACHING MOWER TO TRACTOR:
-Operate latch control to open hitch latches.
-Drive tractor into position aligning the quick hitch.
-Be sure both latches engage fully and and are placed in the locked position.
-Stop engine! Do not attempt to install drive belt with engine running.
-Release idler assembly to facilitate easy installation of the drive belt.
-Put belt over drive pulleys and engage or adjust idler assembly.
(See Power Unit Operator's Manual for PTO belt tension adjustments.)
-Set mower to desired cutting height.
-Start engine and engage PTO slowly to prevent shock load on mower components.
-Mow with front lift lever in “FLOAT” position only.
REAR WEIGHT REQUIREMENTS
The table of requirements for rear weights is based upon average mowing condi-
tions and operator’s weight of 150 lbs. The recommendations may vary with the weight of
the operator, other accessories, and the mowing conditions. It is the operator’s responsi-
bility to determine the correct amount of weight needed to improve stability. All weights
must be removed when the mower is removed. (See Caution in Power Unit Operator’s
manual.)

SERVICE section 5
MAINTENANCE
Daily 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.
25 hour maintenance:
·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 5-2.
·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 foot pounds.
Annual Maintenance:
·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 foot
pounds. 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 pro-
vided by two slots in the linkage which supports the
front of the deck. This allows each side to be ad-
justed independently. Check the blade level with
mower resting on a level floor 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 de-
grees 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.
