MAINTENANCE INSTRUCTIONS
1. ENGINE:
For complete maintenance and operating information for your engine, please refer to your engine operating and maintenance instructions furnished by the engine manufacturer and included in your Country
Clipper Hydrostatic Drive Walk-behind Mower information packet.
NOTE: Air intake screen must be kept clean. If plugged, engine may be seriously damaged by over heating.
2. TIRES:
Correct tire pressure is essential for efficient operation of the mower. Check tire pressure as requested in the maintenance schedule. Inflate tires to 16 psi.
Lug nuts should be checked regularly for tightness.
Check sharpness of mower blades after every 10 hours of operation. To sharpen blades proceed as follows:
D. Check balance of blade by positioning the blade on a nail or blade balance pedestal.
Grind the blade on the end that is heavier until both sides balance.
E. Install blade, cup washer, lockwasher, and bolt. Make sure to tighten bolt to 60 ft.lbs.
DANGEROUS
DO NOT USE
BLADE IN THIS
CONDITION
New Blade
CAUTION
BEFORE SERVICING BLADE(S). STOP
ENGINE, REMOVE KEY, AND
DISCONNECT SPARK PLUG(S) FOR
SAFETY
A. Remove bolt, lockwasher, and cup washer mounting blade on shaft.
Remove blade.
NOTE: Servicing the underside of the deck can be simplified by raising the deck into the servicing position. See Page 16 on howto raise deck into servicing position.
B. Blades should be discarded when worn excessively.
C. Sharpen blades with a hand file, electric grinder or blade sharpener. Wear gloves and eye protection when sharpening.
Grind blade at original 25 degree bevel.
When notch starts,
DISCARD blade
4. V-BELTS:
All belts should be checked every 50 hours. Replace any belts found to be in poor condition. All belts are equipped with spring loaded belt tighteners and do not require tightening adjustments.
NOTE: See page 19 for belt routings.
5. LUBRICATION:
A. Engine: Follow engine manufacturer’s recommendations.
B. Deck Lubricate with 3 “shots” only, every 100 hours.
C. Hydrostatic Transmission and filter:
Check the oil level in hydrostatic transmission oil reservoir after every 25 hours of usage. The proper oil level should register within the sight window of the oil reservoir cover.
When adding oil be very careful to keep the reservoir clean.
Clean the Oil
Reservoir Cap and the surrounding area prior to removing the Oil Reservoir Cap.
Replenish oil supply as required with
20W-50 Motor Oil. DO NOT OVERFILL.

Change the oil in the reservoir and
Hydrostatic Transmission Filter after the first 100 hours of operation, and then every 500 hours after that. Remove the filter and be sure that all oil has drained from the reservoir. Replace with new filter
(P/N H-2026) and 20W-50 Motor Oil.
WARNING
PORTIONS OF HYDRAULIC SYSTEM CAN
OPERATE UNDER HIGH PRESSURE.
HYDRAULIC FLUID ESCAPING UNDER
PRESSURE MAY HAVE SUFFICIENT FORCE
TO PENETRATE SKIN AND CAUSE SERIOUS
INJURY. HYDRAULIC FLUID INJECTED INTO
THE SKIN MUST BE SURGICALLY REMOVED
WITHIN A FEW HOURS BY A DOCTOR
FAMILIAR WITH THIS FORM OF INJURY OR
GANGRENE MAY RESULT. (see Hydraulic
Schematic on page 20) amounts. If rear drive tire “creeps” into reverse shorten the reverse link rod assembly. Re-tighten lower jam nut when length adjustments are completed. Verify collapsed length of reverse spring. Repeat for other side.
D. NEUTRAL AT THE TWIN TRACK
GROUND SPEED LEVERS i) Move the Twin Track Ground Speed
Levers into neutral position. If rear drive tire is “creeping” forward shorten the forward link rod assembly by loosening and repositioning the jam nuts . Lengthen the forward link rod assembly if the rear drive tire “creeps” into reverse. Repeat for other side.
NOTE: If this adjustment cannot be maintained, verify that spring located on the pivot point of the Twin Track
Ground Speed Levers is collapsed to approximately 11/16”.
A. Raise rear drive tires high enough to clear the ground and securely support.
B. Start engine and run at full throttle.
C. NEUTRAL AT THE SHIFT HANDLES i) Shift the Twin Track Ground Speed
Levers approximately into the middle speed position.
NOTE: Operator Presence Bail must be held down when shifting the Twin
Track Ground Speed Levers out of neutral.

Shift Handle Link ii) Verify that the reverse spring is collapsed to approximately 1-1/16”.
Adjust collapsed length of reverse spring using the spring collapse jam nut. Repeat for other side
NOTE: This can be done prior to starting the engine.

E. NEUTRAL AT NEUTRAL LATCHES i) Shift the Twin Track Ground Speed
Levers into the middle speed position. ii) Squeeze the Shift Handle into neutral
(as previously adjusted). Rotate the
“Thumb Grip” portion of the neutral latch rearward and release the Shift
Handle, locking the Shift Handle into the neutral position. If the rear drive tire “creeps” forward shorten the Shift
Handle Link Rod Assembly. If the rear drive tires “creeps” into reverse lengthen the Shift Handle Link Rod
Assembly.
NOTE: The Shift Handle Link Rod must be disconnected from the Shift
Handle in order to change the length.
7. FORWARD TRACKING ADJUSTMENT:
A. If forward travel of the machine veers left or right on level ground when the Twin
Track Ground Speed Levers are set at the same forward position lengthen or shorten Speed Control Link Rod.
Lengthening the Speed Control Link Rod will increase forward ground speed and shortening the Speed Control Link Rod will decrease forward ground speed.
NOTE: It may be necessary to re-adjust neutral following this adjustment.
8. HYDROSTATIC TRANSMISSION CONTROL
ARM TENSION SETTINGS:
A. For heavy or medium duty drive conditions (i.e. when pulling a sulky unit, or carrying a grass collection system), added spring force might be required on the Control Arm of the Hydrostatic
Transmissions to prevent the hydraulic drive system from slowing down while pulling the extra load.
B. To increase spring force, remove the
Forward Spring from the mounting bolt.
Remove the mounting bolt on the Control
Arm and place it into one of the lower holes. Re-connect the Forward Spring to the Control Arm.
NOTE : The middle hole on the Control
Arm is for “medium duty” service and the bottom hole on the Control Arm is for
“heavy duty” service.
9. LEVELING THE MOWER DECK:
A. Move machine onto hard level surface
(i.e. concrete or blacktop).
B. Set tire pressure on all four tires.
C. Place all four Deck Hanger Hairpins so that deck is in highest cutting height.
D. With all blades tips rotated to point straight forward measure from the ground to the front blade tips. If blade tips measure more than 3/16” different loosen the jam nuts on the Deck Hanger Rods.
Adjust length of the appropriate Deck
Hanger Rods until blade tips are within
3/16” of each other. The rear blade tips should be approximately 1/8” farther from the ground than the front blade tips. The deck should hang firmly on all four Deck
Hanger Rods. Tighten the jam nuts on all four Deck Hanger Rods once desired side-to-side level and front-to-back rake is obtained.

10. RAISING THE DECK TO SERVICE
POSITION:
A. Change deck cutting height to be at the mid-position OR lower.
B. Position the front caster wheel to point away from the deck (such as the mower would be travelling in reverse).

Ball on the idler bar releasing tension on belt. Remove the engine to deck belt from spindles.
D. Remove Rear Deck Hanger Hairpin.
Remove Lynch pin from Rear Deck
Hanger Clevis pin. Remove Rear Deck

DECK MUST BE LIFTED FAR ENOUGH TO GO
“OVER-CENTER”, THUS PREVENTING IT FROM
FALLING ON THE OPERATOR WHILE SERVICE
WORK IS BEING PERFORMED.
Hanger Clevis pin. Re-Install rear Deck
Hanger Hairpin. Repeat for other side.
E. Push down on handle bars until deck fully rotates up to the service position.
11. LOWERING THE DECK TO OPERATION
POSITION:
A. Push down on Handle bars raising the deck off of the ground. Push the machine forward while lowering the deck back to the ground.
B. Remove Rear Deck Hanger Hairpins.
Re-install Rear Deck Hanger Clevis pins and Lynch pins. Re-Install Rear Deck
Hanger Hairpin.
