Safety – Use only an approved container. – Never remove fuel cap or add fuel with engine running. Allow engine to cool before refueling. Do not smoke while refueling. This machine meets or exceeds CEN standard EN 836:1997, ISO standard 5395:1990, and ANSI B71.4-2004 specifications in effect at the time of production. – Never refuel or drain the machine indoors. • Check that operator’s presence controls, safety switches and shields are attached and functioning properly.
Toro Mower Safety • Do not operate the mower under the influence of alcohol or drugs. • Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter. • Use care when loading or unloading the machine into a trailer or truck. • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
• Keep your body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not your hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury. • Before disconnecting or performing any work on the hydraulic system, all pressure in the system must be relieved by stopping the engine and lowering the cutting units to the ground.
Safety and Instructional Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost. 93-6697 1. Read the Operator’s Manual. 2. Add SAE 80w-90 (API GL-5) oil every 50 hours. 106-6753 1. Thrown object hazard—keep bystanders a safe distance from the machine. 2. Cutting/dismemberment hazard of hand or foot, mower blade—stay away from moving parts. 93-7818 1.
115-4505 (Model 30368 only) 1. Warning—read the Operator’s Manual. 2. Tipping hazard—lower the cutting unit when driving down slopes. For 2 wheel drive units, add a 16 kg (35 lb) rear weight to GM 3280D units and a 32 kg (70 lb) rear weight to GM 3320 units. For 4 wheel drive 3280 D units, add a 16 kg (35 lb) rear weight. 108-1988 1. Belt routing 100-5622 1. Height of cut adjustment 107-1622 108-1986 1.

Product Overview Operation Specifications Note: Determine the left and right sides of the machine from the normal operating position. Note: Specifications and design are subject to change without notice. CAUTION If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Width of 60 inches (1.52 m) or 72 inches (1.
Adjusting the Height-of-Cut reverse the machines direction to pull any clippings away from the wheel/fork area. The height-of-cut is adjustable from 1 to 5 inches (25 to 127 mm) in 1/2 inch (13 mm) increments. To adjust the height-of-cut, position the castor wheel axles in the upper or lower holes of the castor forks, add or remove an equal number of spacers from the castor forks and secure the height of cut collar to the desired holes in the height of cut rod. 1.
2. Slide the shaft out of the lower bracket holes, align the roller with the top holes, and install the shaft. 3. Install the screw and nut to secure the assemblies. To adjust the rear (internal) rollers (Figure 12) Figure 10 Figure 12 7. Secure the adjustment with the clevis pin and hair pin. 1. Internal rollers Note: Position the head of the clevis pin toward the front of the deck, if possible.
Adjusting the Anti-Scalp Rollers Whenever you change the height-of-cut, it is recommended to adjust the height of the anti-scalp rollers. 1. After adjusting the height-of-cut, adjust the rollers by removing the flange nut, bushing, spacer, and bolt (Figure 14). 1 2 3 4 G008961 Figure 15 1. Unlock lever 2. Rotate the cam lock to increase or decrease locking pressure 3. Position the baffle 4. Lock lever Positioning the Flow Baffle The following figures are only recommendations for use.
6. Loosen the jam nuts on the bottom of the height-of-cut rods (Figure 19). Figure 17 Figure 19 Position C 1. Height-of-cut This is the full open position. The suggested use for this position is as follows. • Use in tall, dense grass mowing conditions. • Use in wet conditions. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions. 2. Jam nut 7. Rotate the height-of-cut rods to raise or lower the rear of the cutting unit and attain the correct cutting unit pitch.
Using the Side Discharge or other reasons, mow first with the height-of-cut at a high level; then mow again 2–3 days later with a lower height setting. The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Always Mow with Sharp Blades DANGER A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Tighten the castor wheel nuts After the first 10 hours • Tighten the castor wheel nuts • Torque the blade bolts Before each use or daily • Lubricate the castor arm bushings • Lubricate the castor wheel bearings • Check the blades Every 50 hours • • • • • • Check the gear box lubricant Lubricate the grease fittings Tighten the castor wheel nuts Torque the blade bolts Check th
Lubrication Service Interval: Every 50 hours The machine has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base 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. 1. Lubricate the following areas: Figure 22 • Castor fork shaft bushings (2)(Figure 20) • Lift arm pivots, rear (2) (Figure 23) Figure 23 Figure 20 2.
3. Remove the hairpin and clevis pin securing the height of cut collar to the height of cut rod on the rear of the cutting unit (Figure 25). Remove the height of cut collar. 4. Remove the hair pin cotters and clevis pins securing the lift arms to the castor arm brackets (Figure 26). Figure 24 1. Dipstick/fill plug Figure 26 Pre Maintenance 1. Lift arm 2. Clevis pin Important: The fasteners on the covers of this machine are designed to remain on the cover after removal.
Mounting the Cutting Unit to the Traction Unit the thrust washers between the lift arm and the castor arm bracket (Figure 28). Insert end of cotter pin into the slot in the castor arm tab to retain cotter pin. 1. Position the machine on a level surface and shut the engine off. 6. Repeat the procedure on the opposite lift arm. 2. Move the cutting unit into position in front of the traction unit. 7. Start the traction unit and raise the cutting unit. 8.
Checking for a Bent Blade 5. Apply grease to the inside and outside of the new bushings. Using a hammer and flat plate, drive the bushings into the mounting tube. 1. Position the machine on a level surface. Raise the cutting unit, engage the parking brake, put the traction pedal in neutral, put the PTO lever in the Off position, stop the engine, and remove the ignition key. Block the cutting unit to prevent it from accidentally falling. 6. Inspect the castor spindle for wear and replace it if damaged. 7.
cutting edges are sharp. The cutting edge of the blade must be sharp so that the grass is cut rather than torn. A dull cutting edge is evident when the tips of the grass appear brown and shredded. Sharpen the cutting edges to correct this condition. 2 1. Position the machine on a level surface. Raise the cutting unit, engage the parking brake, put the traction pedal in neutral, put the PTO lever in the Off position, stop the engine, and remove the ignition key. 1 2.
Continue to check the alignment of the blades and add shims until the tips of the blades are within the required dimension. Important: Do not use more than three shims at any one hole location. Use decreasing numbers of shims in adjacent holes if more than one shim is added to any one hole location. 7. Install the belt covers. Figure 34 1. Sharpen at original angle Replacing the Drive Belt Note: Remove the blades and sharpen them on a grinder; refer to Removing the Cutting Blades.
4. Route the new belt around the spindle pulleys and idler pulley assembly as shown in Figure 37. Figure 38 1. Bolt 2. Spacer 3. Locknut Figure 37 4. Spring 1. Belt routing 5. Install the belt covers. Replacing the Grass Deflector WARNING An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur.
