Forword The 62” cutting deck has advanced concepts in engineering, design and safety; and if maintained properly, will give excellent service. Certain information in this manual is emphasized. DANGER, WARNING and CAUTION identify personal safety related information. IMPORTANT identifies mechanical information demanding special attention. Be sure to read this directive because it deals with the possibility of damaging a part or parts of the machine.
Safety 3. WARNING—Petrol is highly flammable. 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.
attachments; slope. Travel on grass slopes requires particular care. To guard against overturning: • change into neutral and set the parking brake; • do not stop or start suddenly when going up or downhill; • stop the engine and remove the key. • engage clutch slowly, always keep machine in gear, especially when travailing downhill; 13.
4. To reduce the fire hazard, keep the engine, silencer, battery compartment and petrol storage area free of grass, leaves, or excessive grease. 5. Check the grass catcher frequently for wear or deterioration. 6. Replace worn or damaged parts for safety. 7. If the fuel tank has to be drained, this should be done outdoors 8. On multi-bladed machines, take care as rotating one blade can cause other blades to rotate. 9.

Before Operating Adjusting Height-of-Cut 2 The height of cut is adjustable from 2.5 to 10 cm in 1.25-cm increments, by adding or removing an equal number of spacers from the front and rear castor forks. The height-of-cut chart below gives the combinations of spacers to use for all height-of-cut settings. 4 3 4 Height-of-Cut Chart Height-of-Cut Setting 2.5 cm 3.7 cm 5.0 cm 6,3 cm 7.5 cm 8.7 cm 10.0 cm 1 Spacers Below Castor Arm Front Rear 0 0 1 1 2 2 3 3 4 4 5 5 6 6 Figure 1 1. 2. 3. 4.
2. Align the roller and spacer with the top holes in the brackets and secure with a capscrew and nut. 2. Remove or add “C”-shaped spacers at the narrow portion of the spindle shaft, below the castor arm, to get desired height of cut. Make sure thrust washers—not the spacers—contact the top and bottom of the castor arm. 3. Install the tensioning cap. 4. Assure all four castor wheels are set at same height of cut.
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 lubricant is up to bottom of the hole (Fig. 6). If the level of lubricant is low, remove the fill plug on top of the gear case and add enough lubricant to bring it up to bottom of the hole in the side. 1 2 Figure 6 1. Filler plug 2.
Operating Instructions Grass Deflector (Fig 7) Tension Spring Adjustment For best performance, adjust spring tension so cutting unit bounce on uneven turf is minimal and the deck does not ride heavily over flat terrain. If scalping occurs or the cut is uneven from side to side, there may too much weight on the deck and weight may have to be transferred to the traction unit, i.e., increased spring tension.
Maintenance Grease Bearings, Bushings and Gear Box (Fig. 8-10) 1. The cutting unit has bearings and bushings that must be lubricated, and these lubrication points are: front castor spindle bushings (Fig. 8); front and rear castor wheel bearings (Fig. 8); right and left lift arm pivot pins (Fig. 9); blade spindle bearings (Fig. 10) and right and left ball joints (Fig 10). Figure 10 2. Position machine and cutting unit on a level surface and lower the cutting unit.

Separating the Cutting Unit from the Traction Unit 1 1. Position the machine on a level surface, raise the cutting unit, engage the parking brake, be sure the traction pedal is in neutral position, PTO lever in OFF position, shut engine OFF and remove the key from the switch. 2 Figure 13 CAUTION 1. Castor arm 2. Ball joint mount Counterbalance springs are in dension when the deck is in its lowered position. Always raise the deck before adjusting or removing the springs. 5.
3. Slide the male PTO shaft into the female PTO shaft. 4. Move the lift lever to the FLOAT position. Push the lift arms down until the holes in the ball joint mounts line up with the holes in the castor arms. 5. Secure the ball joint mounts to the castor arms with capscrews and flange nuts.

Connect the counterbalance to the traction unit brackets with lock pins.
bushing from the opposite side of the wheel hub. Checking for a Bent Blade 1. Position the machine on a level surface, raise the cutting unit, engage the parking brake, be sure the traction pedal is in the neutral position, the PTO lever in the OFF position, shut off the engine, remove the key from the switch and disconnect the wires from the spark plugs. Block the cutting unit to prevent it from falling accidentally. 4. Inspect the bearing, spanner bushing and the inside of the wheel for wear.
rather than torn. A dull cutting edge is evident when tips of the grass appear brown and shredded. Sharpen the cutting edges to correct this condition. sure the traction pedal is in neutral position, the PTO lever in the OFF position, shut off the engine, remove the key from the switch and disconnect wires from spark plugs. Block the cutting unit to prevent it from falling accidentally. 1.
other, proceed to step 10 and add shims between spindle housing and bottom of the cutting unit. DANGER If the blade is allowed to wear, a slot will form between the sail and the flat part of the blade (Fig. 19 C). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to yourself or to bystanders. 4. Check to make sure front height-of-cut pins are resting properly on frame cushions.
6. Lift deflector and allow it to drop to check spring tension. Deflector must be held firmly in full downward position by spring tension. Correct if necessary. blade, add a shim, Part No. 3256-24, between spindle housing and bottom of the cutting unit. Continue checking alignment of blades and adding shims until tips of blades are within the required dimension.
5. Install the new belt around the gear box pulley, spindle pulleys, stationary idler pulley and adjustable idler pulley. Adjusting Cover Latches If the cutting unit covers fit loose, latch tension may be adjusted by loosening the latch mounting screws, and sliding the latches (slotted mounting holes in the cutting unit) to the proper position. 6. Install the gear box base with carriage bolts and locknuts. 7.
Model and Serial Numbers The cutting deck has two identification numbers: a model number and a serial number. The two numbers are stamped into a plate which is located on carrier frame behind the right front castor wheel. In any correspondence concerning the mower, supply the model and serial numbers to assure that correct information and replacement parts are obtained. To order repIacement parts from an authorized TORO Distributor, supply the foIlowing information: 1.
