    SETUP AND ADJUSTMENTS Mower Deck Leveling Position machine on a flat surface. Preferably level concrete. Check the tire pressure in all four tires. Inflation should be 15 psi. Place 2x4’s on edge under the cutting deck from front to rear and lower the deck down onto 2x4’s. Adjust the four lower chain bolts to the center slots on the deck.
  • Page 18: Controls

    Presentation This operator’s manual describes the Husqvarna Lever-Steered Rider Mower. The mower is fitted with a liquid cooled, 3 cylinder Daihatsu diesel engine (27 HP) or Daihatsu Turbo diesel engine (34 HP). Transmission from the engine is made via two belt-driven hydraulic pumps, which in turn drive a hydraulic motor for each drive wheel.
  • Page 19: Gauges

    Gauges Water temperature gauge- indicates coolant temperature and warns of overheat situation. Ammeter - indicates amount of electrical flow at the battery. Under normal operating conditions the needle will be slightly on the plus (+) side of the gauge, showing that current is being supplied to the battery.
  • Page 20: Engaging The Mower Deck

    Engaging the Mower Deck In order to engage the mower deck, pull the knob out; the mower deck is disengaged when the knob is depressed. Deck should be engaged at mid throttle and disengaged at idle speed to prolong clutch life. Parking Brake The parking brake is found on the left of the machine.
  • Page 21: Motion Control Levers

    Motion Control Levers The machine’s speed and direction are continuously variable using the two motion control levers. The motion control levers can be moved forward or backward from a neutral position. Furthermore, there is a neutral position, which is locked if the motion control levers are moved outward into the neutral slots.
  • Page 22: Hydraulic Lift Switch

    If the steering controls are in uneven positions when standing still, they can be adjusted using the adjustment screws, not the link system, for the controls Hydraulic Lift Switch Used to raise and lower the mower deck hydraulically. Only used on units with power deck lifts.
  • Page 23: Refueling

    Refueling The machine has two fuel tanks, one on each side just behind the seat. The tanks hold 11.4 gallons, 5.7 gallons each. The engine is run on clean, fresh, diesel fuel with a minumum of 40 cetane. WARNING! Diesel fuel is highly flammable. Observe caution and fill the tanks outdoors (see the safety rules).
  • Page 24: Hydraulic Lift For Mower Deck

    Manual Lifting Lever with Foot Assist for the Mower Deck The lifting lever is used to place the mower deck in the transport position or one of the 17 different cutting height positions. The cutting height is set by placing a pin in the hole for the desired cutting height and the pin is then locked on the inside (hidden in the illustration) with the supplied cotter pin.

    disengaged before the motion control levers can be moved from the neutral slots or the engine will kill. By moving the levers an equal amount forward or back the machine will move in a straight line in that direction. Movement of either lever forward will cause the right or left wheel to rotate in a forward direction.
  • Page 32 dense, the driving speed can be increased without noticeably depreciating the mowing result. • The finest lawns are obtained by mowing often. The mowing becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher driving speed can be used without poorer mowing results.

  • Page 45: Lubrication

    Lubrication Lubrication Schedule Lubrication schedule General Remove the ignition key to prevent unintentional movements during lubrication. When lubricating with an oil can, it should be filled with engine oil. When lubricating with grease, unless otherwise stated, a lithium based grease or another chassis or ball bearing grease, offering good corrosion protection should be used.
  • Page 46: Lubricating The Cables

    Lubricating the Cables If possible, grease both ends of the cable and move the controls to end stop positions when lubricating. Refit the rubber covers on the cable after lubrication. Cables with sheaths will bind if they are not lubricated regularly.
  • Page 47 3. Engine Oil Changing the Engine Oil Change the engine oil and filter for the first time after 50 hours of operation. Thereafter, the oil should be changed every 150 hours and the filter every other oil change. WARNING! Engine oil can be very hot if it is drained directly after stopping the engine.
  • Page 48 The oil level should be between the markings on the dipstick. If the level is approaching the “ADD” mark, add the oil to the “FULL” mark on the dipstick. Never fill above the “FULL” mark. The oil is topped off through the dipstick hole. Use engine oil SAE 30 or SAE 10W-30 or, alternately, 10W/40, class CF - 4, CI - 4 (over 0 °C/+32 °F).
  • Page 49 5. Front Wheel Mount Lubricate with a grease gun, one zerk for each wheel mount, use 10 pumps of the grease gun at the recommended service intervals. Use only good quality lithium based grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality.
  • Page 50 9. Steering Control Shafts Tip the driver’s seat. Lubricate with a grease gun, one zerk for each steering control shaft, until the grease is forced out. Use only good quality lithium based grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality.
  • Page 51 12. Belt Adjuster, Hydraulic Pumps Lubricate using a grease gun, one zerk, until the grease squeezes out. Use only good quality lithium based grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality. IMPORTANT INFORMATION Be careful and remove excess lubricant so that is does not come into contact with belts or belt pulley drive surfaces.
