HITCHING MOWER TO TRACTOR:
For proper mower operation and maximum PTO life, the mower and PTO driveline
must be setup correctly.
a) Lower three point hitch arms on tractor and align them with the lower hitch links
on both ends of the hitch assembly. Insert a 7/8” pin to secure links to lower tractor
arms.
b) Adjust tractor top link length to match distance between top link of mower and
tractor top link mount. Attach with7/8” pin.
c) Raise and lower mower to ensure that it does not come into contact with the
tractor. The links should operate smoothly and should not bind. Note that the SDR-
90 will require front bumper weights.
CONNECTING THE PTO SHAFT:
a) Ensure that the tractor engine is shut off and the parking brake is locked.
b) Holding the PTO against the end of the tractor PTO shaft, rotate the tractor
PTO by hand until the shaft slides on slightly.
c) Slide the locking collar on the PTO backwards, releasing the locking
mechanism. Hold and slide the PTO on.
d) Release the locking ring and pull the PTO shaft backwards until the locking
mechanism snaps into place.
e) Push the shaft forward and backwards to ensure that this is securely locked in
place.
f) NOTE: If mower is being used on another tractor, it is necessary to ensure
that the overall length of the PTO is correct. Check and adjusted per the steps
outlined above
CAUTION - If the PTO shaft comes off during operation, it may
cause personal injury and damage to the PTO shaft and tractor PTO.
When checking, make sure the locking collar is locked, and that the
shaft is not just jammed against the end of the tractor PTO shaft.

Adjusting the PTO shaft to the correct length
IMPORTANT:
When checking driveline PTO shaft minimum length, it is necessary to
align and level the tractor’s PTO shaft with the gearbox shaft of the mower.
1.
Measure the shortest distance possible between the tractor PTO shaft and the gearbox
shaft of the mower. The lower links on the 3 point hitch must be hanging downward to
obtain the shortest length (see diagram 1).
lower links
Diagram 1
2.
Shorten the driveline PTO shaft as follows:
a. Make sure the tractor PTO shaft and the mower PTO shaft are level with each
other.
b. Separate the two driveline shaft halves and connect one half to the tractor PTO
shaft and the other half to the mower gearbox shaft.
c. Hold driveline shaft halves side by side to determine if they are too long. The
shields on each half should end approximately 3” from the universal joint shield.
Measure 3” back from the universal joint shield (dimension X on Diagram 2) and
mark that location on the inner and outer shields.
d. Cut off the outer shield at dimension ‘A’. Measure dimension ‘A’ from the end of
the outer shaft and cut the same amount off of the outer shaft. Cut off the inner
shield at dimension ‘B’. Measure dimension ‘B’ from the end of the inner shaft
and cut the same amount off of the inner shaft.
e. Remove all burrs from shafts. Keep shaft ends square not rounded off. Clean all
filings from drive shield tubes.
f. Once driveline has been reassembled, check to make sure the driveline does not
bottom out in the shortest position.

CUTTING HEIGHT ADJUSTMENT:
There are four height adjusters per mowing deck. Each adjuster (located in each
corner of the deck) must be adjusted to the same height to ensure a smooth even
cut. A wrench for this purpose is provided. In addition, each deck must be
adjusted the same so that a level cut is obtained across the whole cutting width of
the mower. Mower cutting height adjustment is made by turning a 5/8” nut on
top of an acme treaded rod which makes up the height adjuster. A washer under
the nut indicates the height against the decal. There are an infinite number of
adjustments available from ½” to 4”. Moving the adjuster up and down moves a
side rail that mounts the front and rear rollers. Before attempting to make height
adjustments, the locking bolt on the side rail adjacent to the adjuster must be
loosened. When the desired adjustment is made, be sure to tighten the locking
bolt and adjuster jamb nut to maintain the adjusted height. Always adjust so that
the back of the deck cuts slightly higher than the front. Doing this provides a
better cut and requires less horsepower.

An Important Word On Grease Compatibility
What Grease Is:
-Grease is essentially a distilled petroleum product in the form of mineral oil (or a
synthetic) which has a thickening agent such as lithium, calcium, barium, sodium, or
aluminum.
-Many of the thickeners will work for similar situations, but when mixing greases with
different thickeners, one must review compatibility. Grease incompatibility will actually
decrease the lubrication ability of the grease, and cause premature part failure.
-There may be other additives in the grease that impart special properties. These properties
may be “high temperature”, “extreme pressure”, etc.
What We Use:
- Our bearing supplier uses Shell Alvania 2
- Progressive uses Texaco Multifak EP 2
- EP means extreme pressure
- Both greases have: - A mineral oil base
- A lithium thickener
- The mineral oil has a NLGI Grade 2
- Both greases are compatible with each other
Note:
-If a thickener other than lithium is used, the existing grease will be contaminated and the
lubrication properties may be lost.
-If a synthetic base oil is used rather than a mineral base oil, the grease will again be
contaminated and the lubrication properties may be lost
-Molybdenum Disulfide (Moly) is an additive used in slow moving, extreme load
applications. The particles in the “Moly” will actually increase bearing wear in a mower
spindle. Our grease does not contain Moly.
-The blade spindle temperature should never go above 120°F if properly greased; we do
not recommend high temperature grease.
A grease with these features is considered to be a “General Purpose Grease”. Use on all
grease point locations on your Progressive Mower.
Our Recommendation for Grease Compatibility:
The grease you use for the blade spindle assemblies must have these properties:
NLGI grade 2
Lithium thickener (NOT LITHIUM COMPLEX OR LITHIUM 12-HYDROXY)
Kinematic Viscosity at 40°C is no greater than 190 cSt
Dropping Point Less than 400° F
General Purpose Grease, Not Heavy Duty
No MOLY (molybdenum disulphide) additives in the grease
No synthetic grease
No High Temperature Grease
Check the properties of the grease you wish to use with your supplier prior to use.

LUBRICATION:
A properly maintained lubrication schedule will provide a smooth running machine for
many years. The following information shows and describes where all lubrication points
are located.

CHECK FOR PROPER OIL LEVEL IN GEARBOXES DAILY
GREASING SCHEDULE & LOCATION
BLADE SPINDLE GREASING:
The top bearing on all spindle assemblies has a shield only. This allows grease to exit
and relieves any pressure build up inside spindle housing, when greasing. Greasing of
blade spindles should continue until grease can be seen exiting between the top bearing
and the bottom of hub on pulley. Some working conditions will require this operation
to take place every 4 to 5 running hours because of hot working areas. Cooler working
areas will only require greasing every 8 to 10 hours. A proper greasing schedule can
only be determined by operator, depending on working conditions in your particular
area.

GEARBOX OIL LEVEL:
IMPORTANT! DO NOT OVERFILL! MOWER MUST BE LEVEL WHEN
CHECKING GEARBOX OIL LEVEL
DECK GEARBOX:
Gearboxes all have an oil level plug located on the side of the gearbox. Oil should
reach the bottom of this hole. If oil level is low, add oil through top plug hole of casing
until oil just starts to flow out of side oil level hole. Replace and tighten plugs. Use
80W90-gear oil or equivalent.

MAINTENANCE:
WARNING - Turn tractor engine off before performing any
maintenance.
CAUTION - Always use personal protection devices such as eye and
ear protectors when performing maintenance functions.
WARNING - When completing a maintenance or service function,
make sure all safety shields are installed before placing mower in
service.
BLADE SERVICING:
WARNING - Be sure safety locks are in place when working on
decks in the raised position. The tractor hydraulic system could fail,
causing decks to fall and crush anything under them.
Do not handle mower blades with bare hands. Careless or improper handling
may result in serious injury.
Inspect blades before each use to determine that they are mounted tightly and are
in good condition. Replace any blade that is bent, excessively nicked, worn or has
any other damage. Small nicks can be ground out when sharpening.
WARNING - Only original equipment blades should be used when
replacing worn out mower blades. They are made of special steel
alloys and subjected to rigid heat-treat and inspection requirements.
Substitute blades may not meet these rigid specifications and MAY BE
DANGEROUS.

BLADE REMOVAL AND INSTALLATION:
Two, 1/2” X 1 3/4” grade 5 bolts with lock washers and nuts hold blade to
blade spindle support bar. When changing blades, be sure that these fasteners are in
good condition so they will not come loose during operation.
BLADE SHARPENING:
IMPORTANT - When sharpening blades be sure to balance them. Unbalanced
blades will cause excessive vibration, which can damage blade spindle bearings.
Vibration may also cause structural cracks in spindle housing.
Follow original sharpening pattern as shown. Sharpen blade to a razor edge.
Protect hands when sharpening. Do not sharpen backside of blade.

SPINDLE INSPECTION:
Spindles are equipped with two roller ball bearings. Adjustment is set by
tightening the 1” left hand nut to 60 ft-lbs. torque for proper setting.
Periodically inspect blade spindles by grasping blade, and moving from side
to side. If any free play is noted, replace or repair.
SPINDLE ASSEMBLY REMOVAL:
Remove blade from spindle.
Remove belt shield. Loosen 4 bolts that hold gearbox to mount. Loosen
1/2” x 3 1/2” tap bolts and slide gearbox toward front until belt is easy to remove.
Remove belt.
Remove 4 bolts attaching spindle assembly to mower frame and remove as a unit,
since pulley will come out through the hole in the deck.
SPINDLE ASSEMBLY INSTALLATION:
Reverse above procedure. Be sure spindle mounting area of deck is clean of any
foreign material before attaching spindle assembly.
SPINDLE REPAIR:
Spindle repair requires special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in this type of repair, you may
be time and money ahead to use a new spindle assembly.
Remove pulley from spindle assembly. Place assembly in press and force spindle
down through housing. Once pressed apart, replace bearings, as removal will have
damaged bearings internally.
20
Download from Www.Somanuals.com. All Manuals Search And Download.
ASSEMBLY OF SPINDLE:
Only use a press that has the ram and bed 100% square to each other. If bearings
are not square in housing, bearings will wear out prematurely. Press on outer race
when inserting into hub and press on inner race when installing on spindle.
If bearings are being changed, be sure to
check bearing spacer for wear. If wear
is noticed, insert new spacer. This is
critical because if spacer is short by only
.010”, the top bearing will start to bind
and will result in premature failure.
Bearing with seal and shield
combination will be pressed into the
blade side of the hub first with the seal
side facing out. Next, set spindle on
press bed, install dirt shield and shim
first (as per diagram) set hub, bearing
end down, onto spindle. You must use a
tube (Note: both ends must be square)
which will slide over spindle and press
on inner race of bearing, until seated
against shim.
Insert bearing spacer tube with
hole end up. Set remaining bearing with shield side up, open side on first, onto
spindle. Press on inner race (this bearing will be a loose fit in the hub so it will seat
itself properly).
When all parts have been installed on spindle, torque left hand nut to 60 ft-
lbs. and then tighten set screws in pulley. Once the assembly is complete, fill with
quality grease until it can be seen exiting the top bearing. Rotate the housing six
revolutions by hand so the bearings will have the grease worked into them, and at
the same time check for free movement. The assembly is now ready for installation
into the mower deck.

“V” BELT ADJUSTMENT:
Begin by loosening 4 bolts at the base of the gearbox. Adjusting long
threaded bolt slides the gearbox back, tightening belt. After proper tension is
achieved, tighten 4 bolts at base of gearbox. You may have to place a ½” nut under
the head of the long threaded bolt to increase your adjustment length.
When changing belts, removal of grease fitting from the top of the center
spindle will make installation easier. Be sure belts run in proper groove.
“V” BELT TENSION:
Proper belt tensioning is a fundamental factor in the successful V-belt
operation. Lack of tension will cause slippage, and too much tension will cause
excessive belt stretch as well as damage to the drive components, such as bearings
and shafts. Therefore, to ensure proper belt tension, the following procedure is
recommended.
CHECKING BELT TENSION
At the mid-point of the span, apply a deflection force with a spring scale in
the direction perpendicular to the span until the belt is deflected the 3/8”.
The recommended force to deflect the belt is a minimum of 4.9 lbs. to a maximum
of 7.3 lbs.
The first 24 to 48 hours of operation is the belt “run in” period. To ensure
satisfactory belt performance, belt tension should be checked during this time
period.
