Training • Store fuel in containers specifically designed for this purpose. 1. Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. • Refuel outdoors only and do not smoke while refueling. 2. Never allow children or people unfamiliar with these instructions to use the lawnmower. Local regulations may restrict the age of the operator. • Add fuel before starting the engine.
• before cleaning blockages or unclogging chute; • do not stop or start suddenly when going up or downhill; • before checking, cleaning or working on the lawnmower; • engage clutch slowly, always keep machine in gear, especially when travailing downhill; • machine speeds should be kept low on slopes and during tight turns; • after striking a foreign object.
8. On multi-bladed machines, take care as rotating one blade can cause other blades to rotate. 9. When machine is to be parked, stored or left unattended, lower the cutting means unless a Sound & Vibration Levels Sound Levels This unit has an equivalent continuous A-weighted sound pressure at the operator ear of: 88 dB(A), based on measurements of identical machines per 84/538/EEC.

Before Operating CHECK LUBRICANT IN GEAR BOX (Fig. 1) The gear box is designed to operate with SAE 80-90 wt. gear lube. Although the gear box is shipped with lubricant from the factory, check the level before operating the cutting unit. 1. Position the machine and cutting unit on a level surface. 2. Remove the check plug from the side of the gear box and make sure the lubricant is up to the bottom of the hole.
ADJUSTING ROLLERS (Fig. 6) Rollers should be located in the upper holes for 2.5 and 3.8 cm heights of cut and lower holes for 5 to 12.7 cm heights of cut. Five rollers are located on the deck, three under the main deck and one on each wing. Figure 5 1. Adjust the rollers by removing the lock nut and bolt, positioning as desired and then installing the lock nut and bolt. ADJUSTING DECK PITCH (Fig.
as required.
Operating Instructions OPERATING TIPS 1. 2. 3. 4. 12 5. Mow When Grass Is Dry—Mow either in the late morning to avoid the dew, which causes grass clumping or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass. Select The Proper Height-of-Cut Setting To Suit Conditions— Remove one inch or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass you may have to raise your height of cut to the next setting.
Maintenance LUBRICATION right and left push arm ball joints (Fig. 8). GREASE BEARINGS, BUSHINGS AND GEAR BOX (Fig. 8) 2. The cutting unit must be lubricated regularly. If the machine is operated under normal conditions, lubricate the castor bearings and bushings with No. 2 general purpose lithium base grease or molybdenum base grease, after every 8 hours of operation or daily, whichever comes first. Lubricate fittings immediately after every washing, regardless of the interval listed. 1.
CAUTION To prevent accidental starting of the engine while performing maintenance, shut of the engine and remove the key from the ignition switch. 1 DISCONNECTING THE CUTTING UNIT FROM THE TRACTION UNIT (Fig. 9–11) Note: Implements are heavy and may require two people to handle. Figure 9 1. Start the tractor and raise the deck to the highest possible position and turn off the engine. 2. Remove the hair pin cotter and clevis pin securing the height-of-cut straps to the rear height-of-cut brackets. 3.
flat hard surface. 2. Raise the seat and open the needle valve. This allows the lift arms to float freely. 3. Adjust the lift arms heights, making sure that the machined surface on top of each traction unit lift arm is parallel to the ground (Fig. 11). (Raise or lower the lift arm casting by pushing up or down from behind the front tires or by using a wrench in front of the tractor) 4. 1 Check for dirt and debris on mating parts and clean as required. 5.
lift arms line up and slide on. 8. Move the deck from side to side to check for tightness and re-tighten the latches, if required. 9. Install the latch covers to the lift arms and secure them with clevis pins and hair pin cotters. 10. Connect the drive shaft to the traction unit. 11. Close the needle valve and lower the seat. 12. Start the tractor and raise the deck to the highest possible position. Then turn off the engine. 13.
8. Pull on the spring loaded idlers and install wing belts. 9. Install belt covers to top of the cutting unit. SERVICING THE FRONT BUSHINGS IN THE CASTOR FORKS (Fig. 14) The castor forks have bushings pressed into the top and bottom of the casting and after many hours of operation, the bushings will wear. To check the bushings, move the castor fork back and forth and from side to side. If castor spindle is loose around the bushings, the bushings are worn and must be replaced. 1.
SERVICING CASTOR WHEELS AND BEARINGS (Fig. 15) The castor wheel rotates on a high-quality roller bearing. Even after many hours of use, provided that the bearing was kept welllubricated, bearing wear will be minimal. However, failure to keep the bearing lubricated will cause rapid wear. A wobbly castor wheel usually indicates a worn bearing. 1. Remove the locknut from the capscrew holding the castor wheel assembly between the castor fork. Grasp the castor wheel and slide the capscrew out of the fork. 2.
5. Install blade sail facing (up) toward the cutting unit with the cup and blade bolt. Tighten the blade bolt to 115–145 Nm. WARNING Do not try to straighten a blade that is bent, and never weld a broken or cracked blade. Always use a new blade to assure continued safety certification of the product. INSPECTING AND SHARPENING THE BLADE (Flg. 17–18) 1. Raise the cutting unit to the highest position, shut the engine off and engage the parking brake. 2.
7. edge must be lower than the heel of the blade. This blade will produce good quality of cut and require minimal power from the engine. By contrast, a blade that is higher at the ends than the center, or that has a cutting edge higher than the heel, is bent or warped and must be replaced. be added. To raise or lower the blade, add a shim, Part No. 3256-24, between spindle housing and bottom of cutting unit.
