GENERAL INFORMATION

The purpose of this manual is to assist you in

operating and maintaining your mower. Read it

carefully. It furnishes information and instructions that

will help you achieve years of dependable perform-

ance. These instructions have been compiled from

extensive field experience and engineering data.

Some information may be general in nature due to

unknown and varying operating conditions. However,

through experience and these instructions, you

should be able to develop procedures suitable to your

particular situation.

The illustrations and data used in this manual were

current at the time of printing, but due to possible

inline production changes, your machine may vary

slightly in detail. We reserve the right to redesign and

change the machines as may be necessary without

SAFETY RULES

ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

Safety is a primary concern in the design and

manufacture of our products. Unfortunately, our

efforts to provide safe equipment can be wiped

out by an operator’s single careless act.

In addition to the design and configuration of

equipment, hazard control and accident preven-

tion are dependent upon the awareness, con-

cern,judgement,andpropertrainingofpersonnel

involved in the operation, transport, maintenance

and storage of equipment.

It has been said “The best safety device is an

informed,carefuloperator.” Weask youtobethat

kind of operator.

Cutting Height Adjustment (Figure 3)

IMPORTANT

J Avoid low cutting heights. Striking the

ground with blades produces one of the

most damaging shock loads a mower can

encounter. Allowing blades to contact

ground repeatedly will cause damage to

mower and drive.

WARNING

J Keep all persons away from operator

control area while performing adjust-

ments, service or maintenance.

Figure 3. Cutting Height Adjustment

Level mower from side to side. Check by measuring

from mower frame to the ground at each deck rail.

Adjust, using tractor 3-point arm leveling device.

Best mowing results will be obtained with front of

mower level with or slightly lower than the rear.

Cutting height is controlled with tractor 3-point arms

and front and rear caster wheel adjustment. Optional

check chains are available.

WARNING

J Never go unde r ne a th equipme nt low-

er e d to the ground or ra is e d, unles s it is

properly blocked and secured. Never

plac e a ny par t of the body underne a th

equipment or between moveable parts

even when the engine has been turned off.

Hydraulic system leak down, hydraulic

system failures, mechanical failures or

movement of control levers can cause

equipment to drop or rotate unexpectedly

and cause severe injury or death. Follow

To raise rear of mower, move caster adjustment

spacers under caster arms. Hex opening of blade

wrench fits bolts on top of caster shaft.

To raise front of mower, raise tractor 3-point arms,

shorten optional check chains or move spacers under

front caster wheel arms.

The cutting height is the distance between the blade

and the ground. The blades are 7-3/4” below the top

of the deck rail on the RM550 (8-3/4” below the top of

the deck rail on the RM660). To check cutting height,

place a straight edge along top edge of deck rail as

shown in Figure 3.

Measure from bottom of straight edge to the ground

at locations “A” and “B”. Subtract 7-3/4” on RM550

(8-3/4” on RM660) from measurement “B” to deter-

mine cutting height.

IMPORTANT

J Donot operatetractorand moweruntil

this interference check has been per-

formed. If you change tractors, you must

perform the check for that mounting.

Perform this check with all of the spacers and springs

above the caster wheel arm. This will place the caster

wheels in their highest position and provide the lowest

cutting height for the mower.

Raise mower with tractor hydraulics to 16” at

dimension “C” or maximum height of tractor lift,

whichever is less.

Pivot both front caster wheels forward and check that

there is clearance between caster wheels and tractor

tires. If there is interference, you must not use front

caster wheels on the mower with this tractor .

scalping in most cases. However, you may encounter

areas where the caster wheels and/or side skids drop

into depressions and allow center of mower to contact

ground and scalp. An optional front roller may be

installed to minimize scalping.

Pre-Operation Check List

(OWNER RESPONSIBILITY)

Review and follow safety rules on pages 4

through 7.

Check that mower is properly and securely

attached to tractor.

Make sure driveline spring-activated locking pin

slides freely and is seated firmly in tractor PTO

spline groove.

Operate tractor PTO at 540 rpm.

Lubricate all grease fitting locations. Make sure

PTO shaft slip joint is lubricated.

Check to be sure gearbox is half-full of SAE 90W

gear lube.

Check that all hardware is properly installed and

secured.

Check to ensure blades are sharp and secure

and cutting edge is positioned to lead in a

clockwise rotation.

Check that all shields and guards are properly

installed and in good condition.

Check cutting height and attitude adjustment.

Place tractor PTO and transmission in neutral

before starting engine.

Inspect area to be cut and remove stones,

branches or other hard objects that might be

thrown, causing injury or damage.

IMPORTANT

J Mower vibration tends to loosen bolts

during operation. All hardware should be

checked regularly to maintain proper

torque. It is a good practice to check

mower before each operation to ensure all

hardware is secure.

Operating Technique

Power for operating mower is supplied by tractor

PTO. Operate PTO at 540 rpm. Know how to stop

tractor and mower quickly in case of an emergency.

Should mower become plugged, causing belt to slip

for over two seconds, maneuver equipment into a

previously cut area and allow mower to clear

accumulated material. Continue running at least two

minutes, allowing pulleys to cool. Stopping the mower

in contact with a very hot pulley will bake and ruin belt.

CAUTION

J Stop tractor and implement immedi-

ately upon striking an obstruction. Turn

off engine, remove key, inspect and repair

any damage before resuming operation.

Proper ground speed will depend upon the terrain, the

height, type and density of material to be cut.

Normally, ground speed will range from two to five

mph. Tall dense material should becut at a low speed;

thin medium-height material can be cut at a faster

ground speed.

Always operate tractor PTO at 540 rpm. This is

necessary to maintain proper blade speed and

produce a clean cut.

Under certain conditions, tractor tires may roll some

grass down and prevent it from being cut at the same

height as the surrounding area. When this occurs,

reduce your ground speed, but maintain PTO at 540

rpm. The lower ground speed will permit grass to at

least partially rebound.

In general, lower cutting heights give a more even cut

with less tendency to leave tire tracks. However , it is

better to cut grass frequently rather than too short.

Short grass deteriorates rapidly in hot weather and

invites weed growth during growing seasons. Follow

local recommendations for the suitable cutting height

in your area.

PN 55191 (4/22/99)

Tips

WARNING

J Inspect and clear area of stones,

branches or other hard objects that might

be thrown, causing injury or damage.

Extremely tall material should be cut twice. Set

mower at a higher cutting height for the first pass.

Then cut at desired height at 90° to the first pass.

Remember, sharp blades produce cleaner cuts and

require less power.

Analyze area to be cut to determine the best

procedure. Consider height and type of grass and

terrain type: hilly, level or rough.

Plan your mowing pattern to travel straight forward

whenever possible. Mow with uncut grass to the left.

This will distribute the clippings over the cut area.

Discharging clippings over uncut grass will cause a

buildup and may prevent uniform cutting.

Uneven Terrain

WARNING

J Do not operate on steep slopes.

J Do notstop, startor changedirections

suddenly on slopes.

J Use extreme care and reduce ground

speed on slopes and rough terrain.

J Watch for hidden hazards on the ter-

rain during operation.

Pass diagonally through sharp dips and avoid sharp

drops to prevent “hanging up” tractor and mower.

Practice will improve your skills in maneuvering rough

terrain.

Removing Mower from Tractor (Figure 6)

Disengage tractor PTO, raise mower with 3-point

hitch and remove check chains (if installed) from

brackets attached to tractor top link brackets.

Disconnect mower driveshaft from tractor PTO.

Collapse driveshaft as far as possible and store it in

PTO hanger bracket to prevent ground contact. Place

blocks under mower side skids. Lower mower onto

blocks, disconnect mower from tractor 3-point hitch,

and carefully drive tractor away from mower.

BLOCKING METHODS

Jackstands, with a load rating of 1,000 pounds or

more, are the only approved blocking device for this

mower. A minimum of four jackstands, located under

the mower as shown in Figure 7A, must be installed

before working underneath this unit. Do not position

jackstands under wheels, axles, or wheel supports

because these components can rotate.

Do not work underneath unless it is properly attached

to tractor (see Operation section), the brakes set, key

removed, and the mower blocked securely. The

mountedunit will be anchored to minimize side to side

and front to rear movement.

For the mounted unit, tighten tractor lower 3-point

arm anti-sway mechanisms to prevent side to side

moveme nt.

When blocking, you must consider overall stability of

the unit. Just placing jackstands under the unit will not

ensure your safety. The working surface must be level

and solid to support the weight on the jack stands.

Ensure jackstands are stable both top and bottom,

and mower is approximately level. With full mower

weight lowered on jackstands, test blocking stability

before working underneath mower.

LUBRICATION INFORMATION (Figure 7)

Do not let excess grease collect on or around parts,

particularly when operating in sandy areas.

Figure 7 shows the lubrication points. The accompa-

nying chart gives the frequency of lubrication in

operating hours, based on normal operating condi-

tions. Severe or unusual conditions may require more

frequent lubrication. Some reference numbers have

more than one location; be sure you lubricate all

locations.

Use a lithium grease of #2 consistency with a MOLY

(molybdenum disulfide) additive for all locations. Be

sure to clean fittings thoroughly before attaching

grease gun. When applied according tothe lubrication

chart, one good pump of most guns is sufficient.

Use SAE 90W gear lube in the gearbox. Check

gearbox using dipstick. Oil level is to be up to the ring

but not over. See Figure 7.

Check gearbox daily for evidence of leakage at both

seals and the gasket between the housing and cover.

If leakage is noted, repair immediately. There may be

a small amount of lube emitted from the vent plug; this

is not considered leakage.

Overfilling the gearbox will cause the excess gear

lube to blow out vent plug. The gear lube could then

ruin the belt.

PN 55191 (4/22/99)

Driveshaft Lubrication

Lubricate the driveshaft slip joint every 8 operating

hours. Failure to maintain proper lubrication could

result in damage to U-joints, gearbox and driveshaft.

Lower mower to ground.

Apply grease at location as shown in Figure 7.

Raise and lower mower several times to distribute

grease.

BELT REPLACEMENT (Figure 8)

One of the major causes of belt failure is improper

installation. Before a new belt is installed, check

pulley shafts and bearings for wear. Check pulley

grooves for cleanliness. Make sure spindles turn

freely and without wobble. If grooves require clean-

ing, moisten a cloth with a non-flammable, non-toxic

degreasing agent or commercial detergent and water.

Avoid excessive force during installation. Do not use

tools to pry belt intopulley groove. Do not roll belt over

pulleys to install. This can cause hidden damage and

premature belt failure.

IMPORTANT

J Use care when installing or removing

belt from spring-loaded idler at step 5.

Springs store energy when extended and,

if released suddenly, can cause personal

injury.

frame and remove spindle.

Spindle Repair Tips

As a reference point, the top of spindle housing is the

short portion.

To minimize wear, bearing cups, cones and sleeves

are press fit to shaft and will require a press or similar

device for removal.

When disassembling, support housing casting to

prevent damage.

Remove bearing cups by placing a punch in housing

slots and drive cup out. Alternate punch positions

from side to side. Use care to prevent housing

damage.

Bore-tite



sealant is used on the outer diameter of the

seals. Substitute seals may not meet original equip-

ment specifications and could cause leakage.

Blade Spindle Disassembly (Figure 11)

Support spindle in a press and push shaft (7) down

through housing (5).

Remove seals from housing.

Remove bearing cups from housing as described in

Spindle Repair T ips section.

Remove bearing cone (4) from shaft (7).

Blade Spindle Assembly (Figure 11)

Bearing cups and cones are designed to work

together. It is important to position them so bearing

cone taper mates with bearing cup taper.

Lubricate new cups (6) with a light oil. Place them in

spindle housing (5) so they will mate with cones (4).

Seat cups (6) against machined shoulder of housing

with a press or by placing a large drift on the flat lip

and driving them into housing.

Place bottom bearing cone (4) onto spindle shaft (7)

with taper up. Seat on bottom shoulder of shaft with a

press.

Insert shaft and bearing cone assembly through

bottom of housing (5). Fill housingcavity with a lithium

grease of #2 consistency with a MOLY (molybdenum

disulfide) additive. Place top bearing cone (4) on shaft

(7) to mate with top bearing cup.

IMPORTANT

J Bearing adjustment is set by pressing

sleeve against bearing cone until proper

adjustment is attained.

Install sleeve (3) on shaft and press sleeve and

bearing cone onto shaft until all bearing free play is

removedandthere is a slight drag (similar to adjusting

the front wheel bearings on an automobile). Check by

spinning spindle. It should turn freely.

Be careful not to overtighten bearings. Proper bearing

adjustment is essential to good bearing life.
