Make necessary repairs before resuming operations. Keep hands and feet away from the cutting units. Look behind and down before backing up to be sure of a clear path. Never carry passengers and keep pets and bystanders away.
• If the cutting unit discharge area ever plugs, shut the engine off before removing the obstruction. • Cut grass slopes carefully. Do not start, stop, or turn suddenly. • Do not touch the engine or muffler while the engine is running or soon after it has stopped because these areas could be hot enough to cause burns. Maintenance and Storage • Check the blade mounting bolts frequently to be sure that they are tightened to specification.

WARNING DANGER If you leave the key in the ignition switch, someone could accidentally start the engine and seriously injure you or other bystanders. If the engine is started and the PTO shaft is allowed to rotate, serious injury could result.
Product Overview Specifications Note: Specifications and design are subject to change without notice. Width of cut 2.54 m (100 inches) Height of cut Adjustable from 25 to 127 mm (1 to 5 inches) in 6 mm (1/4 inch) increments Net weight 358 kg (790 lb) g027696 Figure 3 Trailer Dimensions Ensure that your trailer or transport vehicle (Figure 2) has enough room to carry the deck in addition to the traction unit.
Operation Note: Determine the left and right sides of the machine from the normal operating position. 4. CAUTION Wing Decks If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.
the appropriate number of 1/2 inch spacers onto the spindle shaft to get the desired height of cut; then slide the washer onto the shaft. in the higher position when operating in height of cuts lower than 64 mm (2-1/2 inches). Note: When using 25 mm (1 inch), 38 mm (1-1/2 inch), or occasionally 51 mm (2 inch) height of cut, move the skids and roller to the highest holes. 4. Secure the adjustment with the tensioning cap. Adjusting the Skid(s) 1. Disengage the PTO and set the parking brake. 2.
4. Using a short ruler, measure from the floor to the front tip of the blade. 5. Rotate the same blade tip to the rear and measure from the floor to the tip of the blade at the rear of the mower. 6. Subtract the front dimension from the rear dimension to calculate the blade pitch. 7. Adjust the U-bolt jam nuts (Figure 8) securing the rear deck chains (Figure 9) to the mower deck to raise the rear of the mower so that the blade pitch is set to 8 to 11 mm (5/16 to 7/16 inch).
Using the Transport Latches grass at this setting. Then cut the grass again using the lower, normal setting. Before transporting the machine, raise the wing decks and secure the wing deck transport latches (Figure 11). Keeping the Mower Clean Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Tighten the caster wheel nuts. After the first 10 hours • Tighten the caster wheel nuts. After the first 50 hours • Change the mower deck gearbox lubricant. Before each use or daily • Lubricate the caster arm bushings. • Lubricate the caster wheel bearings. • Check the mower blades. Every 50 hours • Lubricate the grease fittings. • Tighten the caster wheel nuts.

Lubrication Service Interval: Every 50 hours The machine has grease fittings that must be lubricated regularly with #2 general-purpose, lithium-based grease. If the machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation or immediately after every washing.
6. Remove the dipstick/fill plug from the top of the gearbox (Figure 20) and make sure that the lubricant is between the marks on the dipstick. g025658 Figure 18 • Spindle shaft bearings (5) (Figure 19) g014267 Figure 20 1. Fill plug and dipstick 7. 2. Drain location If the lubricant level is low, add enough lubricant until the level is between the marks on the dipstick. Note: Do not overfill the gearbox, or the gearbox may be damaged.
Servicing the Drive Belts Refer to Figure 21 for routing the drive belts appropriately. decal121-5498 Figure 21 Belt routing Servicing the Bushings in the Caster Arms The caster arms have bushings pressed into the top and bottom of the tube and after many hours of operation, the bushings will wear. To check the bushings, move the caster fork back and forth and from side to side. If the caster spindle is loose inside the bushings, the bushings are worn and must be replaced. 1. 2. 3. 4.
Servicing the Caster Wheels and Bearings 1. turns grass brown at the edges, which slows growth and increases the chance of disease. Check the blades daily for sharpness, and for any wear or damage. Sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade. Remove the locknut from the bolt holding the caster wheel assembly between the caster fork (Figure 23).

Measure from a level surface to the cutting edge, position A, of the blades (Figure 25). Note this dimension. 5. Rotate the opposite ends of the blades forward. 6. Measure from a level surface to the cutting edge of the blades at the same position as in step 3 above.
WARNING Contact with a sharp blade can cause serious injury. Wear gloves or wrap sharp edges of the blade with a rag. 1. Hold the blade end using a rag or a thickly-padded glove. 2. Remove the blade bolt, the anti-scalp plate, and the blade from the spindle shaft (Figure 28). Sharpening the Blades WARNING When sharpening blade, pieces of blade could be thrown and cause serious injury. Wear proper eye protection when sharpening blades. 1. Sharpen the cutting edge at both ends of the blade (Figure 26).
Adjusting the Deck-Limit Chains 3. At the front of the deck, fully loosen the outboard serrated-flange nuts securing the 4 U-bolts (Figure 30). Use 2 deck shims Toro Part No. 138-8243 or 2 feeler gauges—0.15 mm (0.060 inch) Preparing the Deck 1. Start the engine, lower the left and right decks, shut off the engine, remove the key, and wait for all moving parts to stop. 2. At the outer decks, wipe clean the tab of the inner channel (Figure 29). g321237 Figure 30 2. U-bolt 1.
