Safety ◊ lack of awareness of the effect of ground conditions, especially slopes; This machine meets or exceeds CEN standard EN 836:1997, ISO standard 5395:1990 (when appropriate decals applied), and ANSI B71.4-2004 specifications in effect at the time of production when equipped with rear weight as listed in the implement Operator’s Manual. ◊ incorrect hitching and load distribution.
Operation • • Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. • Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area. • Mow only in daylight or in good artificial light. • Before attempting to start the engine, disengage all blade attachment clutches, shift into neutral, and engage the parking brake. • Do not put hands or feet near or under rotating parts.
• On multi-spindle mowers, take care as rotating one blade can cause other blades to rotate. • Disengage drives, lower the deck, set parking brake, stop engine and remove the key from the ignition. Wait for all movement to stop before adjusting, cleaning or repairing. • Clean grass and debris from decks, drives, silencers/mufflers, engine and underside of machine to help prevent fires. Clean up oil or fuel spillage. • Use jack stands to support components when required.
Maintenance and Storage Posterior • Make sure all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. • 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.

flat terrain. If scalping occurs or the cut is uneven from side to side, there may be too much weight on the deck and the weight may have to be transferred to the machine: i.e. increased counterbalance pressure. 1 By contrast, if too much weight is transferred to the machine, the deck will bounce excessively and the cut will be uneven. If the cutting unit does not perform properly, adjust the counterbalance pressure as follows: Front of machine 2 1.

Product Overview Figure 14 1. Steering wheel 2. Traction pedal 3. Brakes 4. Cutting unit 5. Hood/engine compartment 6. ROPS (Rollover Protection System) Controls Service Brakes The left and right brake pedals (Figure 15) are connected to the left and right front wheels. Since both brakes work independently of each other, the brakes can be used to turn sharply or to increase traction if one wheel tends to slip while operating on certain slope conditions.
Parking Brake Whenever the engine is shut off, the parking brake must be engaged to prevent accidental movement of the machine. To engage the parking brake, push the lock arm (Figure 16) on the left brake pedal so that it locks together with the right pedal. Next, push down fully on both pedals and pull the parking brake knob out (Figure 15) then release the pedals. To release the parking brake, press both pedals until the parking brake knob retracts.
Hydraulic Lift Lever The hydraulic lift lever (Figure 19) has three lever positions that actuate four operating modes; LIFT, LOWER, FLOAT & HOLD. To lower the deck, in preparation for mowing, move the lever forward and then allow the lever to freely return. This will allow the deck to drop at a controlled rate and enables the deck ground following float function.
Charge Indicator Operation Illuminates when the system charging circuit malfunctions (Figure 19). This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Oil Pressure Warning Light The oil pressure warning light (Figure 19) glows when the oil pressure in engine drops below a safe level. If low oil pressure ever occurs, stop the engine and determine the cause. Repair the damage before starting the engine again.
If the engine has been running, pressurized hot coolant can escape when the radiator cap is removed and cause burns. 1. Check the level of the coolant in the expansion tank (Figure 23). The coolant level should be between the marks on the side of the tank. Figure 21 1. Dipstick 3. If the oil level is below the Full mark, remove the fill cap (Figure 22) and add oil until the level reaches the Full mark on the dipstick. Do not overfill.. Figure 23 1. Expansion tank 2.
Adding Fuel from reputable manufacturers who will stand behind their recommendation. Material Properties: Viscosity, ASTM D445 The engine runs on clean, fresh diesel fuel with a minimum octane rating of 40. Purchase fuel in quantities that can be used within 30 days to ensure fuel freshness. cSt @ 40°C 55 to 62 cSt 140 @ to 100°C 152 9.1 to 9.8 Viscosity Index ASTM D2270 Pour Point, ASTM D97 -35°F to -46°F Industry Specifications: API GL-4, AGCO Powerfluid 821 XL, Ford New Holland FNHA-2-C-201.
2. Using a clean rag, clean area around fuel tank cap. 3. Remove cap from the fuel tank (Figure 25). In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Never fill the fuel tank inside an enclosed trailer.
The fluid level should be up to the hole in the clutch. If the fluid level is low, add Mobil Fluid 424. The clutch should be approximately 1/3 full. 4. Install the check plug. Note: Do not use engine oil (i.e. 10W30) in the bidirectional clutch. Anti-wear and extreme pressure additives will cause undesirable clutch performance. Note: Determine the left and right sides of the machine from the normal operating position. Figure 26 Using the Rollover Protection System (ROPS) 2. Fill plug 1.
seconds. Release the key when the engine starts. If additional preheating is required, turn the key to the Off position, then to the On/Preheat position. Repeat this process as required. 6. Run the engine at idle speed or partial throttle until it warms up. Note: Move the throttle to the Fast position when restarting a warm engine.
Checking the Interlock System Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. The purpose of the safety interlock system is to prevent the engine from cranking or starting unless the traction pedal is in neutral and the PTO switch is in the Off position.
Pushing or Towing the Machine 3. Start the engine momentarily after the repairs are completed and make sure the pins are in the full disengaged (fully up) position. In an emergency, the machine can be pushed or towed for a very short distance. However, Toro does not recommend this as standard procedure. Important: Running the machine with the by-pass valve open will cause the transmission to overheat.
Figure 33 Here are the logical troubleshooting steps for the SCM device. 5. If specific output LED is illuminated without appropriate output function, check output harness, connections, and component. Repair as required. 1. Determine the output fault you are trying to resolve (PTO, Start, or ETR). 6. If specific output LED is not illuminated, check both fuses. 2. Move key switch to the On position and ensure the red power LED is illuminated. 7.
If the input LED’s are correct, check the output LED. If the output LED is illuminated but the device is not energized, measure available voltage at the output device, continuity of the disconnected device, and potential voltage on the ground circuit (floating ground). Repairs will vary depending on your findings. Operating Tips • Practice driving the machine before initial operation because it has a hydrostatic transmission and its characteristics are different than some turf maintenance machines.

The most common reason for failure is moisture and contamination working its way past the protective seals. Bearings that are greased will rely upon regular maintenance to purge harmful debris from the bearing area.
Engine Maintenance with no detrimental characteristics such as high heat, noise, looseness or indications of corrosion (rust). Note: Determine the left and right sides of the machine from the normal operating position. Due to the operating conditions these bearing/seal packages are subject to (i.e. sand, turf chemicals, water, impacts, etc.) they are considered normal wear items. Bearings that fail due to causes other than defects in materials or workmanship are typically not covered under warranty.
6. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister. Important: Do not apply pressure to the flexible center of the filter. 7.

Adjusting the Traction Drive for Neutral If the machine moves when the traction pedal is in the neutral position, adjust the traction cam. 1. Park the machine on a level surface and turn the engine off. 2. Raise one front wheel and one rear wheel off of the floor and place support blocks under the frame. Figure 55 1. Mounting bolt (4) If the machine is not supported adequately, it may accidentally fall, injuring anyone under the machine.
Model 30345 The engine must be running so a final adjustment of the traction adjustment cam can be performed. Contact with hot or moving parts can result in personal injury. The rear wheels should not toe-in or toe-out when they are adjusted correctly. To check the rear wheel toe-in, measure the center-to-center distance at wheel hub height, in front and in back of the rear tires. If the wheels toe-in or toe-out, an adjustment is required.
Cooling System Maintenance Cleaning the Radiator and the Screen Service Interval: Every 200 hours Figure 60 Every 1,500 hours 1. Steering stop (right side shown) Every 1,500 hours 2. Loosen the screw on the tie rod clamp. To prevent the engine from overheating, the screen and radiator must be kept clean. Normally, check the screen and radiator daily and, if necessary, clean any debris off these parts.
Brake Maintenance 6. Press down on the parking brake rod and push up on the switch until the compressed length of the switch plunger is 0.030 inches (Figure 62, inset) . This is the distance between the brake rod paddle and the switch plunger housing. Adjusting the Parking Brake Interlock Switch 7. Tighten the switch mounting screws and nuts. 1. Turn the engine off and remove the ignition key. Do not engage the parking brake. 2.
Belt Maintenance Checking the Alternator Belt Service Interval: Every 200 hours After the first 10 hours Check condition and tension of alternator belt (Figure 64) after every 200 operating hours. 1. Proper tension will allow 3/8 inch (10 mm) deflection when a force of 10 lb is applied on the belt, midway between the pulleys. 2. If the deflection is not 3/8 in. (10 mm), loosen the alternator mounting bolts. Figure 63 1. Brake cable jam nuts 3. Tighten the front nut after the brakes are adjusted correctly.
Controls System Maintenance Adjusting the PTO Clutch Service Interval: Every 200 hours 1. Turn the engine off, set the parking brake, and remove the ignition key. 2. Raise the engine hood and allow the engine to cool. 3. Adjust the air gap so that a 0.015 inch feeler gauge slides in between the clutch lining and friction plate with light pressure (Figure 66). The gap can be decreased by turning the adjusting nut clockwise (Figure 66). The maximum service gap is 0.030 inch. Adjust all three air gaps.
