MAINTENANCE  
						

							Safety System
The machine is equipped with a safety system that prevents starting or driving under the following conditions.
The engine can only be started when:
• the mower deck is disengaged.
• the steering controls are in the outer, locked neutral position.
• the park brake is on.
IMPORTANT INFORMATION  To be able to drive, the driver must sit in the seat and release the park brake before the steering controls can be moved into the neutral position, otherwise the engine will stop.
Tire Pressures
All tires should be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION  DO NOT add a tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures.
Only use O.E.M. specified tires.
Park Brake
Visually check that no damage is found on the lever, links, or switch belonging to the park brake. Perform a standstill test and check that there is sufficient braking action.
To adjust the park brake, contact the Husqvarna service workshop.
  WARNING!  Faulty adjustment will result in reduced braking ability and can cause an accident.
V-belts
Check every 100 hours of operation. Check for severe cracking and large nicks.
NOTE: The belt will show some small cracks in normal operation.
Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met. Change the conditions and try again.
If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again.
Make sure the engine stops when the park brake is not engaged and the operator leaves the seated position.
Check that the engine stops if the mower blades are engaged and the driver temporarily moves off the driver’s seat.

26 
MAINTENANCE  
						

							Cutting Blades
To attain the best mowing effect, it is important that blades are well sharpened and not damaged.
Replace blades that have been bent or cracked when hitting obstacles.
Let the service workshop decide whether a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening.
Check the blade mounts.
Blade Replacement
1. Remove blade bolt by turning it counter clockwise.
2. Install new or re-sharpened blade with stamped GRASS SIDE facing towards ground/grass (down) or THIS SIDE UP facing deck and cutter housing.
3. Install and tighten blade bolt securely.
4. Torque blade bolt to 90 ft-lbs (122 Nm).
IMPORTANT INFORMATION  Special blade bolt is heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware than specified.
Adjusting the Mower Deck
Leveling Deck
Adjust the deck while the mower is on a level surface. Make sure the tires are inflated to the correct pressure. See Tire Pressures in Maintenance section. If tires are under or over inflated, the deck cannot be properly adjusted. Faulty mower deck adjustments will cause an uneven mowing result.
Four bolts control the height and pitch of the mower deck. The deck should be adjusted slightly higher in the rear.
NOTE: To insure accuracy of leveling procedure, mower deck drive belt must be installed prior to leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip to align with the deck side-to-side.
2. Measure from the floor surface up to the bottom of the blade tip on the discharge side of the mower deck. Record this measurement. Move to the opposite side; check that measurement is the same. If adjustment is required, loosen the locknut and adjust bolt up until both side-to-side measurements are equal. Retain measurement.
3. Turn both outer blades to align with the deck front-to-rear. Reposition rear mounting bolts up or down until rear blade tips are positioned 1/8" to 3/8" higher in the rear than the front blade tips.
4. Confirm measurements once again. Blade tip height should be equal in a side-to-side manner. In the rear, blade tips should be 1/8" to 3/8" higher than the front measurement. In the front, blade tips should be equal from side-to-side.
3. With a 1/2" breaker bar and using the square opening in the idler arm, shift the arm to create slack in the belt. While holding the idler back with the breaker bar, wrap the belt around the right pump pulley.
4. Replace and secure clutch stop. Reinstall the deck belt.
  CAUTION!  Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
The sharpening of blades should be carried out by an authorized service workshop.
NOTE: This will place the mower deck in a standard measurement position. Depending on the type of grass being mowed or environmental conditions, additional adjustments may be required to achieve the desired cut.
27 
MAINTENANCE  
						

							Anti-scalp Rollers
Anti-scalp rollers keep the deck in the proper position to help prevent scalping in most terrain conditions. Do not adjust the rollers to support the deck.
IMPORTANT INFORMATION  Adjust anti-scalp rollers with the mower on a flat level surface.
To avoid deck damage, the anti-scalp rollers must not be adjusted to support the deck.
Anti-scalp rollers can be set in three positions.
• Upper position 1-1/2" to 2-1/2" grass
• Middle position 2-1/2" to 4" grass
• Lower position 4" to 5" grass
The rollers should be approximately 1/4" from ground. Do not adjust the rollers to support the deck.
Caster Wheels
Check every 200 hours. Check that wheels rotate freely.
To replace, remove nut and caster bolt. Pull the wheel out of the fork. Install in reverse order. Tighten caster bolt. Torque to 45 ft-lbs (61 Nm), then back nut off 1/2 turn.
NOTE: Tire should rotate freely but axle spacers should not. If wheels do not rotate freely take the unit to the dealer for service.
Cleaning
Regular cleaning and washing, especially under the mower deck, will increase the machine’s life-span. Make it a habit to clean the machine directly after use (after it is cooled), before the dirt sticks.
Do not spray water on the top of the mower deck. Use compressed air to clean the top side of mower deck. Regularly clean deck and underside of the deck with normal water pressure. Do not use a high pressure washer or steam cleaner. Avoid spraying engine and electrical components with water.
Do not rinse hot surfaces with cold water. Let unit cool before washing.
Hardware
Check daily. Inspect the entire machine for loose or missing hardware.
ZT-3400 Powertrain
IMPORTANT INFORMATION  Servicing dealers attempting a warranty repair must have prior approval before conducting maintenance to a Hydro-Gear® product, unless the servicing dealer is a current Authorized Hydro-Gear Service Center.
Regular external maintenance of the ZT-3400 Powertrain™ should include the following:
1. Check oil level in expansion tanks. When the engine is cold, the tanks should be at the FULL COLD level.
2. Inspect the vehicle drive belt, idler pulley(s), and idler spring(s). Insure that no belt slippage can occur. Slippage can cause low input speed to the transmission.
3. Inspect the transmission cooling fan for broken or bent blades. Remove obstructions such as grass clippings, leaves or dirt.
4. Inspect the park brake and vehicle linkage to insure proper action and adjustment of the park brake.
5. Inspect the vehicle control linkage to the directional control arm on the transaxle. Also, make sure the control arm is securely fastened to the trunnion arm of the transaxle.

LUBRICATION  
						

							Drain old oil filters of all free-flowing oil prior to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area.
Transaxle Fluid Change
This transaxle is designed with an external filter for ease of maintenance. To ensure constant fluid quality levels and longer life, an oil filter change interval of every 200 hours is recommended.
The following procedure is performed with the transaxles installed in the mower and the mower on level ground. Apply the pump release valve for each transaxle and set the park brake.
1. Remove the three filter guard screws and filter guard. Clean loose debris from around the perimeter of the filter. See illustration.
2. Place an oil drain pan (12" or more diameter and 8 qt. capacity is optimal) beneath the oil filter. Remove the oil filter from the transaxle.
3. After the oil has drained, wipe the filter base surface and apply a film of new oil to the gasket of the replacement filter.
4. Install the new filter by hand, turning it three-quarters to one full turn after the filter gasket contacts the filter base surface.
5. Reinstall the filter guard. Torque screws to 65 in/lbs. each.
6. Repeat steps on the opposite side.
7. Drain old oil filters of all free flowing oil prior to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area.
8. Remove the top port plug (see illustration) from the left side and right side of the transaxles prior to filling with oil. This will allow the transaxles to vent during oil fill.
9. Remove the cap from the transaxles’ expansion tank located on the vehicle frame.
Wheel and Deck Zerks
Use only good quality bearing grease.
Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality.
Front Wheel Mount
Remove dust cap to expose zerk. Lubricate with a grease gun until the grease is forced out around the top washer.
Front Wheel Bearings
Lubricate 3-4 strokes with a grease gun on each set of wheel bearings.
Deck Spindles
Lower the cutting deck completely.
If a grease gun without rubber hose is used, the foot plate must be removed to access the center spindle.
Lubricate with a grease gun, 2-3 strokes per spindle.
IMPORTANT INFORMATION Use minimal lubrication and remove excess lubricant so that is does not come into contact with belts or belt pulley drive surfaces.
