Product Overview Figure 14 1. Steering wheel 2. Traction pedal 3. 4. Brakes 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.
Traction Pedal The traction pedal (Figure 17) has two functions: one is to make the machine move forward, the other is to make it move rearward. Using the heel and toe of the right foot, press the top of the pedal to move forward and the bottom of the pedal to move rearward. Ground speed is proportionate to how far the pedal is pressed. For maximum ground speed, the traction pedal must be fully depressed while throttle is in the Fast position. Maximum speed forward is 10 mph (approx.).

Charge Indicator Illuminates when the system charging circuit malfunctions (Figure 19). 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. Lift Lever Lock Lock the lift lever (Figure 19), in the raised position, when performing maintenance on the deck. Figure 20 1.
Operation This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Adequate rear weight is necessary to prevent the rear wheels from leaving the ground. Do not stop suddenly while deck or implement is raised. Do not travel down hill with the deck or implement raised. If the rear wheel leaves the ground, steering is lost. Figure 21 1. Dipstick 3.
products from reputable manufacturers who will stand behind their recommendation. If the engine has been running, pressurized hot coolant can escape when the radiator cap is removed and cause burns. Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation. 1. Check the level of the coolant in the expansion tank (Figure 23).
Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. • Avoid prolonged breathing of vapors. • Keep face away from nozzle and gas tank or conditioner opening. • Keep fuel away from eyes and skin. Figure 24 1. Hydraulic system reservoir uid/add dipstick cap 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. 3.
In certain conditions during fueling, static electricity can be released causing a spark which can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property. • Always place fuel containers on the ground away from your vehicle before filling. • Do not fill fuel containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
Figure 28 Figure 26 1. Check plug 2. 1. Fill plug Bidirectional clutch 2. Check plug 3. Remove the check plug. 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.
4. To raise the roll bar, remove the hairpin cotter pins and remove the two pins (Figure 29). There is no rollover protection when the roll bar is in the down position. 5. Raise the roll bar to the upright position and install the two pins and secure them with the hairpin cotter pins (Figure 29). • Lower the roll bar only when absolutely necessary. Important: Always use the seat belt when the roll bar is in the raised and locked position. Do not use the seat belt when the ROPS is in the lowered position.
Important: When engine is started for the first time, or after an engine oil change, or overhaul of the engine, transmission, or axle, operate the machine in forward and reverse for one to two minutes. Also operate the lift lever and PTO lever to ensure proper operation of all parts. Turn the power steering wheel to the left and right to check the steering response. Then shut the engine off and check fluid levels, check for oil leaks, loose parts, and any other noticeable malfunctions. 3.
Important: Do not push or tow the machine faster than 2 to 3 mph because the transmission may be damaged. If the machine must be moved a considerable distance, transport it on a truck or trailer. Whenever the machine is pushed or towed, the by-pass valve must be open. 1. Loosen the knob and remove the access cover at the rear of the seat mounting plate (Figure 31). If the safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.
Important: Running the machine with the by-pass valve open will cause the transmission to overheat. closed to ground. Each input has a LED that is illuminated when the specific circuit is energized. Use the input LED’s for switch and input circuit troubleshooting. 4. Install the access cover. Output circuits are energized by an appropriate set of input conditions. The three outputs include PTO, ETR, and START.
6. If specific output LED is not illuminated, check both fuses. Each row (across) in the logic chart below identifies input and output requirements for each specific product function. Product functions are listed in the left column. Symbols identify specific circuit condition including: energized to voltage, closed to ground, and open to ground. 7. If specific output LED is not illuminated and inputs are in appropriate condition, install new SCM and determine if fault disappears.
• Another characteristic to consider is the operation of the brakes. The brakes can be used to assist in turning the machine; however, use them carefully, especially on soft or wet grass because the turf may be torn accidentally. The brakes can be used to control the direction of the deck when trimming along fences or similar objects. The other benefit of the brakes is to maintain traction. For example; in some slope conditions, the uphill wheel slips and loses traction.

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.
under normal use, but periodic inspections of bearing condition and seal integrity should be conducted to avoid downtime. These bearings should be inspected seasonally and replaced if damaged or worn. Bearings should operate smoothly with no detrimental characteristics such as high heat, noise, looseness or indications of corrosion (rust). 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.
Changing the Engine Oil And Filter Important: Avoid using high pressure air which could force dirt through the filter into the intake tract. Check oil level after each day’s operation or each time machine is used. Change oil and filter initially after first 50 hours of operation; change oil and filter after every 150 hours of operation thereafter. If possible, run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil. 4.
Fuel System Maintenance Replacing Fuel Pre Filter Replace the fuel pre filter (Figure 51), located between fuel tank and fuel pump after every 400 operating hours or yearly, whichever occurs first. Note: Refer to Filling the Fuel Tank for proper fuel recommendations. 1. Clamp both fuel lines that connect to the fuel filter so fuel cannot drain when the lines are removed (Figure 51). Servicing the Water Separator Drain water or other contaminants from water separator (Figure 50) daily.
Electrical System Maintenance Important: Ensure that the arrow on the side of the filter points toward the injection pump. Servicing the Battery Fuel Lines and Connections Warning Check the fuel lines and connections every 400 hours or yearly, whichever comes first. Inspect them for deterioration, damage, or loose connections.
Important: Whenever working with the electrical system, always disconnect the battery cables, negative (-) cable first, to prevent possible wiring damage from short-outs. the clamps and terminals separately. Reconnect the cables, positive (+) cable first, and coat the terminals with petroleum jelly. Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.
Changing the Bidirectional Clutch Lubricant (Model 30345 only) Change the oil in the bidirectional clutch after every 400 hours of operation. 1. Position the machine on a level surface. 2. Clean the area around the check plug on the bidirectional clutch. 3. Rotate the clutch so that the check plug is positioned downward (Figure 56). Figure 54 1. Drain plugs (3) 2. Tie rod 3. Remove the plugs allowing the oil to drain into drain pans. 4.
5. Tighten the screw securing the adjustment. 6. Stop the engine. If the machine is not supported adequately, it may accidentally fall, injuring anyone under the machine. 7. Adjust the screw on the neutral return arm (Figure 57) until the gap between the end of the screw and the switch contact is .090–.120 inch. One front wheel and one rear wheel must be raised off of the ground or the machine will move during adjustment. 8. Remove the support blocks and lower the machine to the shop floor. 9.
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. 1. Rotate the steering wheel so rear wheels are straight ahead. 2. Remove nuts securing one tie rod ball joint to the mounting bracket on the axle and disconnect the ball joint from the axle (Figure 59). Figure 60 1. Steering stop (right side shown) 2. Loosen the screw on the tie rod clamp. 3. Rotate the ball joint in or out to adjust the length of the tie rod. 4.
Brake Maintenance Adjusting the Parking Brake Interlock Switch 1. Turn the engine off and remove the ignition key. Do not engage the parking brake. 2. Remove the knob from parking brake rod and screws from the steering tower cover (Figure 61). Figure 62 1. Parking brake interlock switch 2. Parking brake rod paddle 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) .
The brakes should be checked for adjustment after the first 10 hours of operation and should only need adjusting after considerable use thereafter. These periodic adjustments can be performed where the brake cable connects to the bottom of the brake pedals. When the cable is no longer adjustable, the star nut on the inside of the brake drum must be adjusted to move the brake shoes outward. However, the brake cables must be adjusted again to compensate for this adjustment. 1.
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. Figure 65 1. Tensioning spring 2. Tensioning rod jam nut 3. Tension adjusting bolt Figure 66 4. Use a 1/2 inch wrench to tighten or loosen the belt tensioning spring (Figure 65).
Adjusting the Tilt Steering Control 1. Remove the knob from the parking brake and screws from the steering column cover (Figure 69). Figure 67 1. Traction pedal stop 3. If more adjustment is required, adjust traction rod (Figure 68) as follows: Figure 69 1. Parking brake knob A. Remove the bolt and nut securing traction rod end to the pedal. B. Loosen the jam nut securing rod end to the traction rod. 2. Mounting screw (4) 2.
Hydraulic System Maintenance Note: Fluid to operate the power steering is supplied by the hydraulic system transmission charge pump. Changing the Hydraulic Oil And Filter Cold weather start-up may result in stiff operation of the steering until the hydraulic system has warmed up. Using proper weight hydraulic oil in system will minimize this condition. Initially, replace the hydraulic oil filter after the first full day’s operation.
7. Fill the axle (reservoir) to the proper level (approximately 6 quarts); refer to Checking the Hydraulic Fluid. 8. Remove jack stands. 9. Start the engine, cycle the steering and lift cylinders, and check for oil leaks. Allow the engine to run for about five minutes, then shut it off. 10. After two minutes, check the level of the hydraulic fluid; refer to Checking the Hydraulic Fluid.
Storage 2. Remove and discard the oil filter. Install a new filter. Machine 3. Refill the engine with 4 quarts (3.8 l) of recommended motor oil. Refer to Changing the Engine Oil. 1.
