PREPARATION FOR USE
10126W MULTI-SPINDLE ROTARY MOWER 4
CHECK
Danger
NEVER attempt any checks, repairs or adjustments
with the tractor engine running or the power take-off
engaged. Adjustment of rotating parts while the tractor
engine is running can result in serious personal injury or
death if the PTO accidentally engages.
Gearbox Lube Level
The gearbox is filled with lubricant at the factory. If a
shaft seal or cover gasket is damaged, the lubricant will
leak. After periods of heavy use (at least every 10 hours
of operation), or if lubricant leaks are observed, check
the lubricant level.
 Position mower on a level surface.
 Visual check and look for leaks in shaft and open
plate cover and check for oil in blade pan.
 Remove gearbox lubricant level inspection plug and
check lubricant level. Lubricant should be at or near
the hole.
 If lubricant is low, remove gearbox Fill/Pressure
Relief Plug (P/N 15664) and add SAE 85-140
lubricant until lubricant starts to flow from level
inspection hole. DO NOT OVERFILL. Overfilling will
induce leakage and cause damage to seals and
gaskets.
 Replace Lubricant Level Plug and Fill/Pressure
Relief Plug (P/N 15664).
Note: DO NOT OPERATE THE MOWER WHEN
LUBRICANT LEVEL IS LOW. Replace damaged seals
or gasket and add lubricant to the correct level. DO
NOT OVERFILL.
Checking Gearbox Lubricant Level
Blade and Blade Holder Condition
 Lift and support mower by an approved means.
Danger
The mowers weigh BETWEEN 1,525 and 3,590 pounds
and will cause severe injury or death if one falls on the
operator during maintenance. Support the mower with a
supporting device having a capacity for at least 1 ½
times the weight of the mower (e.g. – 2,170 pound
mower = 3,255 pound lifting device capacity).
 Check mower blades for sharpness and condition.
Replace worn mower blades in pairs only. Sharpen
dull mower blades in pairs only.
Note: It is a good practice to weigh blades after
sharpening to ensure balance.
Danger
Excessively worn or dull mower blades, or the
replacement or sharpening of only one mower blade,
can cause excessive mower vibration, resulting in
damage to the gearbox and structural damage to the
mower. Excessive vibration can cause rotating parts to
break and fly off the mower, causing serious injury or
death to the operator or bystanders.
 Lock blade holder so it will not turn.
 Remove blade holder shaft cotter pin.
 Check blade holder nut for tightness. Tighten as
required.
Danger
A loose blade holder shaft can cause the shaft to break,
causing the holder to fly out, damaging the mower and
causing serious personal injury or death to the operator
or bystanders. Ensure that the nut is tight on the shaft
and the cotter pin is securely in place.
 Replace blade holder shaft cotter pin.
 Remove supporting means and lower mower.
Blade Attaching Hardware
 Rotate blade bolt access cover (on top of mower
deck in front of the gearbox) from covering over the
access hole.
 Turn blade holder to position blade bolt under
access hole.

Positioning Hitch Upper Arm
Drawbar (Pull Type Cutter)
Adjust the tractor drawbar so that the hole is 14 inches
behind the end of the PTO shaft and parallel to the
tractor centerline. The vertical distance for the drawbar
centerline to the driveshaft centerline should be 8 to 15
inches.
 Back tractor until drawbar is in line with mower
hitch.
 Connect mower to tractor drawbar with a A 1 inch
drawbar pin.
 Connect mower hydraulic system (if used) to tractor
auxiliary hydraulic system.

Hardee by EVH
PREPARATION FOR USE
10126W MULTI-SPINDLE ROTARY MOWER 6
 Lift tractor PTO guard.
 Pull U-joint guard back along driveshaft.
 Press driveshaft yoke plunger in and slip driveshaft
U-joint yoke onto splined PTO shaft. Check that
plunger returns to locked position.
 Position U-joint guard over driveshaft U-joint.
 Lower Tractor PTO guard.
ADJUSTMENT
Slip Clutch
Mowers are equipped with a slip clutch on the driveshaft
to protect the tractor and mower drivetrain parts from
sudden overloads. When properly adjusted, the clutch
will slip to relieve excess loads and automatically reset
itself without interrupting the mower operation.
To compensate for clutch plate face wear and to maintain
capacity during continuous use, the slip clutch must be
adjusted periodically. Adjust the slip clutch at the
beginning of each use, and when the mower has been
idle for extended periods.
Danger
NEVER attempt any repairs or adjustments with the
tractor engine running or the power take-off engaged.
Adjustment of rotating parts while tractor engine is
running can result in serious personal injury or death if
the PTO accidentally engages.
 Remove slip clutch safety shield by removing the
retaining clip and sliding shield back along the
driveshaft.
 Loosen slip clutch adjusting nuts.
 Check clutch plate assembly. Free plates by lightly
tapping on flat edges of drive plates if required.
Note: Slip clutches have a tendency to seize if left idle for
extended periods.
Danger
Ensure that all bystanders are clear of the mower before
the tractor engine is started. Objects thrown by the
mower can cause severe personal injury or death.
 Start tractor engine and engage power take-off at low
rpm for one or two seconds to remove any rust or
other foreign material between the slip clutch plates.
 Disengage PTO, turn off tractor, set brake and
remove key. Ensure that all rotary motion has
stopped before dismounting the tractor.
 Remove clutch safety shield.
Adjusting Slip Clutch
 Tighten clutch adjusting nuts alternately and evenly
1/2 turn at a time until springs have compressed to
between 1 1/8” to 1” in length.
 Scribe a chalk line across clutch drive plate and
driven plate to mark their position relative to one
another.
Note: The drive plate is on the U-joint side of the slip
clutch. The driven plate is on the gearbox side.
Note: If plates still can be rotated by hand when springs
are compressed to the limit, new plates must be installed.
Refer to parts breakdown for correct part number.
 Replace clutch safety shield after adjustments are
complete.
 Operate rotary mower for three or four minutes under
normal load.
 Disengage PTO, turn off tractor, set brake and
remove key. Ensure that all rotary motion has
stopped before dismounting tractor.
 Remove safety shield.
 Observe chalk lines on clutch plates. If clutch is not
slipping under normal load, chalk marks will still be
aligned. Clutch is correctly adjusted. If clutch is
slipping, chalk lines will not be aligned.
Note: If chalk is not available, the following method may
be used to check for clutch slippage.
 Carefully check if clutch is overheating by holding
hand near clutch. If slipping has occurred, allow
clutch to cool before adjusting.

Warning
DO NOT touch the slip clutch with bare hands
immediately after operation. Severe skin burns and
component damage may result if the clutch is adjusted
while hot.
 Repeat above procedure until heating and slippage
are eliminated.
 Replace clutch safety shield after adjustments are
complete.
Mowing Height
Danger
The mower must be operated on a level plane at all
times to minimize the risk of objects being thrown out
from under the mower. Objects thrown by the mower
can cause severe personal injury or death.
Safety chain shielding is highly recommended to
minimize the danger of objects being thrown out from
under the mower. Safety chain shielding is available
from Hardee By EVH Mfg. and authorized Hardee
dealers and distributors. Safety belting comes standard
on all mowers.
Leveling Lift Type Mower
Hook mower to tractor, transport mower to level area if
not at one already. Lower the mower to about six (6)
inches above the ground. If not level adjust third arm of
tractor until front and rear of mower are equal heights
above the ground.
Danger
To minimize the possibility of personal or mechanical
injury from objects being thrown from under the mower,
it must be operated level at all times.
Leveling Pull Type Mower
For initial hook-up and leveling, hook mower tongue to
tractor’s drawbar, if they do not align use tongue jack to
move the tongue. Make sure that the two parking stands
are in the up position. After hook-up is achieved, if
optional cylinder is used, connect hydraulic lines to
tractor. Make sure hoses and fittings are tight and in
good condition. Raise mower with ratchet jack or with
optional hydraulic cylinder to travel height and move
mower to a level area if not already at one. Once at a
level area, lower mower to about six (6) inches above
the ground. Measure the height at the front and rear of
the deck to see if there are any differences in height. If
heights are within a half inch difference, install drive
shaft and shields and proceed with mowing. If heights
are more than a half inch, you must adjust leveling
turnbuckles. To do so, block mower at side skids about
six (6) inches above the ground to take the pressure off
the turnbuckles. To raise the front of the mower, shorten
rod length, to lower the front of the mower lengthen rod
length. Loosen lock nuts and start adjusting turnbuckles.
Note: You must adjust turnbuckles in equal increments
so one will not bind the other.
After adjusting turnbuckles, remove blocks and measure
heights again. If mower is still un-level, repeat process
above until level is achieved. When mower is level,
install drive shaft and shields and proceed with
operation. When mowing is completed, and mower is
ready for unhooking, lower parking stands to a height
that would allow tractor to easily connect to mower.
Tongue jack may be needed to allow parking stands to
line up parking stand holes.
This is an initial adjustment for parallel lift operation and
need not be repeated as long as the mower is used with
a tractor having the same drawbar height.
Adjusting Mowing Height (Lift and Pull
Type)
Cutting height is achieved by using the ratchet jack or by
the optional hydraulic cylinder. If ratchet jack is used,
jack cutter down until it is about two (2) inches above the
ground. This is the recommended cutting height. In
loose or moist soil additional clearance may be needed.
If hydraulic cylinder is used, lower the mower to two (2)
or three (3) inches above the ground. With the hydraulic
cylinder two (2) spacers are supplied, in two different
sizes. Measure the space between cylinder body and
the stop. Used spacer that comes closest to fitting and
this will lock your mower at the working mower height.
For more height add spacers.
Danger
Mowing with mower to high above the ground will cause
debris to be thrown from under the mower, causing
serious personal injury to operator or bystanders. Make
sure mower is at recommended height at all times when
mower is being operated.

10126W MULTI-SPINDLE ROTARY MOWER 8
CAUTIONS
Danger
Incorrect operation of the mower may produce
hazardous situations that can lead to serious injury or
death. The mower has been designed to minimize the
risks of accidents, but there is no substitute for a careful
operator.
Note: See SAFETY PRECAUTIONS in the
introduction section for a list of safety related cautions
to be observed while operating mower.
Lights, SMV Emblems
If operating along public roads, warning lights or slow
moving vehicle emblems should be used unless
prohibited by law. Check local and state codes.
Low Speed
Slow the tractor down when approaching trees, fences,
ditches or other obstacles. The flywheel effect of the
blade rotation will move some tractors forward after the
main drive clutch has been disengaged. To stop
forward movement, apply tractor brakes and throttle the
engine back to allow the engine to slow the rotor before
disengaging the PTO or drive clutch.
NORMAL PROCEDURES
Traveling (Lift Type Mower)
Raise the mower to its maximum height when traveling.
Additional ground clearance can be obtained by
shortening the tractor hitch center arm. NEVER engage
PTO while mower is in traveling position WITHOUT a
cutting load.
Mower in Traveling Position
Warning
Transporting the mower at maximum height changes
the center of gravity of the tractor. Do not travel at high
rates of speed with the mower in traveling position,
especially over rough or bumpy terrain. Tractor
instability during high-speed travel can cause a rollover,
resulting in serious personal injury or death.
Traveling (Pull Type Mower)
Raise the mower to its maximum height when traveling.
To do so, use ratchet jack or optional hydraulic cylinder
to bring mower to traveling position.
Mower in Operating Position
Mowing
 Watch for holes, rocks, roots or other hidden
hazards.
 Keep away from drop-offs.
 Do not cut near the edge of a gully or bank.
 Slow down before turning.
 Engage PTO as directed by tractor manufacturer.
Reverse Operation
Do not operate the mower in reverse unless absolutely
essential.
Caution
DO NOT operate mower in reverse unless absolutely
essential and is allowed by the tractor manufacturer.
Reverse PTO operation may damage tractor drivetrain.
Material may be thrown out through the front of the

Hardee by EVH
OPERATION
10126W MULTI-SPINDLE ROTARY MOWER 9
mower during reverse operation, posing a hazard to the
operator and bystanders. Mow in reverse only if
optional safety chain shielding or safety belting is
installed on the mower.
 Look behind mower before putting tractor in
reverse gear.
 Back tractor at lowest speed available
 Watch back of mower at all times while backing.
Slopes
Cut down, not across, steep slopes. Avoid sudden
starts and stops. Avoid mowing up steep slopes. Slow
down before changing direction on steep slopes.
Sharp Turns
When turning with the mower, ensure that the rear
tractor wheels do not strike any part of the mower.
Extremely short turns should be avoided to prevent
excessive U-joint wear.
HEIGHT ADJUSTMENT
Warning
The mower must be operated on a level plane at all
times to minimize the risk of objects being thrown out
from under the mower. Objects thrown by the mower
can cause severe personal injury or death.
