switches, and shields are attached and functioning properly. Do not operate unless they are functioning properly.

Operation

• Never run an engine in an enclosed area.

• Only operate in good light, keeping away from holes

and hidden hazards.

• Be sure all drives are in neutral and parking brake is

engaged before starting the engine. Only start the engine from the operator’s position.

• Slow down and use extra care on hillsides. Be sure to

travel in the recommended direction on hillsides. Turf conditions can affect the machine’s stability.

• Slow down and use caution when making turns and

when changing directions on slopes.

• Never operate with the guards not securely in place.

Be sure all interlocks are attached, adjusted properly, and functioning property.

• Do not change the engine governor setting or

overspeed the engine.

• Stop on level ground, lower implements, disengage the

auxiliary hydraulics, engage parking brake, shut off the engine before leaving the operator’s position for any reason.

• Keep hands and feet away from moving attachments.

Preparation

• Evaluate the terrain to determine what accessories and

attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by the manufacturer.

• Wear appropriate clothing including hard hat, safety

glasses, long pants, safety shoes, and ear protection. Long hair, loose clothing or jewelry may get tangled in moving parts.

• Look behind and down before backing up to be sure of

a clear path.

• Never carry passengers and keep pets and bystanders

away.

• Slow down and use caution when making turns and

crossing roads and sidewalks.

• Do not operate the machine under the influence of

alcohol or drugs

• 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.

• Read all attachment manuals.

• Ensure that the area is clear of other people before

operating the traction unit. Stop the traction unit if anyone enters the area.

• Never leave a running traction unit unattended.

Always lower the loader arms, stop the engine, set the parking brake, and remove the key before leaving.

• Do not exceed the rated operating capacity, as the

traction unit may become unstable which may result in loss of control.

• Do not carry a load with the arms raised. Always carry

loads close to the ground.

• Do not over-load the attachment and always keep the

load level when raising the loader arms. Logs, boards, and other items could roll down the loader arms, injuring you.

• Never jerk the controls; use a steady motion.

• Watch for traffic when operating near or crossing

roadways.

• Do not touch parts which may be hot from operation.

Allow them to cool before attempting to maintain, adjust, or service.

• Check for overhead clearances (i.e. branches,

doorways, electrical wires) before driving under any objects and do not contact them.

• Before digging, have the area marked for underground

utilities, and do not dig in marked areas.

• Locate the pinch point areas marked on the traction

unit and attachments and keep hands and feet away from these areas.

Slope Operation

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution.

• Do not operate the traction unit on hillsides or slopes

exceeding the angles recommended in the Stability Data section, page 11, and those in the attachment operator ’s manual. See also the slope chart on page 6.

• Operate up and down slopes with the heavy end of

the traction unit uphill. Weight distribution changes.

An empty bucket will make the rear of the traction unit the heavy end, and a full bucket will make the front of the traction unit the heavy end. Most other attachments will make the front of traction unit the heavy end.

• Raising the loader arms on a slope will affect the

stability of the machine. Whenever possible, keep the loader arms in the lowered position when on slopes.

• Removing an attachment on a slope will make the rear

of the traction unit heavy. Refer to the Stability Data section, page 11, to determine whether the attachment can be safely removed on the slope.

• Remove obstacles such as rocks, tree limbs, etc. from

the work area. Watch for holes, ruts, or bumps, as uneven terrain could overturn the traction unit. Tall grass can hide obstacles.

• Use only Toro-approved attachments. Attachments can

change the stability and the operating characteristics of the traction unit. Warranty may be voided if used with unapproved attachments.

• Keep all movements on slopes slow and gradual. Do

not make sudden changes in speed or direction.

• Avoid starting or stopping on a slope. If the traction

unit loses traction, proceed slowly, straight down the slope.

• Avoid turning on slopes. If you must turn, turn slowly

and keep the heavy end of the traction unit uphill.

• Do not operate near drop-offs, ditches, or

embankments. The traction unit could suddenly turn over if a track goes over the edge of a cliff or ditch, or if an edge caves in.

• Do not operate on wet grass. Reduced traction could

cause sliding.

• Do not park the traction unit on a hillside or slope

without lowering the attachment to the ground, setting the parking brake, and chocking the tracks.

Attachments

Many attachments are available for use with the traction unit. These attachments allow you to to perform many different functions with the traction unit such as hauling materials, digging holes, grading, and more. Contact your Toro dealer for a list of all approved attachments and accessories.

Important Use only Toro-approved attachments.

Stability Data

The following tables list the maximum slope recommended for the traction unit in the positions listed in the tables. Slopes over the listed degree may cause the traction unit to become unstable. The data in the tables assume that the loader arms are fully lowered; raised arms may affect the stability.

In each attachment manual is a set of three stability ratings, one for each hill position. To determine the maximum slope you can traverse with the attachment installed, find the degree of slope that corresponds to the stability ratings of the attachment. Example: If the attachment installed on a TX 420 traction unit has a Front Uphill rating of B, a Rear Uphill rating of D, and a Side Uphill rating of C, then you could drive forward up a 20° slope, rearward up a 12° slope, or sideways on a 14° slope, as listed in the following table for the TX 420 traction unit.

Before Operating

Before operating, check the fuel and oil level, and remove debris from the traction unit. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines.

Adding Fuel

Use unleaded gasoline (87 pump octane minimum). Leaded, regular gasoline may be used if unleaded is not available.

Danger

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline 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 gasoline that spills.

• Do not fill the fuel tank completely full. Add

gasoline to the fuel tank until the level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

• Never smoke when handling gasoline, and stay

away from an open flame or where gasoline fumes may be ignited by a spark.

• Store gasoline in an approved container and

keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

• Always place gasoline containers on the ground

away from your vehicle before filling.

• Do not fill gasoline 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.

• When practical, remove gas-powered

equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

• If this is not possible, then refuel such

equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

• If a gasoline dispenser nozzle must be used,

keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Important Do not use methanol, gasoline containing

methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the traction unit to provide the following benefits:

• Keeps gasoline fresh during storage of 90 days or less.

For longer storage it is recommended that the fuel tank be drained.

• Cleans the engine while it runs

• Eliminates gum-like varnish buildup in the fuel

system, which causes hard starting

Important Do not use fuel additives containing

methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the

gas. Note: A fuel stabilizer/conditioner is most effective when

mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

1. Park the traction unit on a level surface, lower the

loader arms, and stop the engine.

2. Remove the key and allow the engine to cool.

3. Clean around the fuel tank cap and remove it.

4. Add unleaded gasoline to the fuel tank, until the level

is just below the bottom of the filler neck.

Important This space in the tank allows gasoline to

expand. Do not fill the fuel tank completely full.

5. Install the fuel tank cap securely.

6. Wipe up any gasoline that may have spilled.

Checking the Oil Level

1. Park the traction unit on a level surface, lower the

loader arms, and stop the engine.

2. Remove the key and allow the engine to cool.

3. Open the hood; refer to Opening the Hood, page 23.

4. Clean around the oil dipstick (Fig. 4).

m-5232

6. Clean any debris build-up on the engine and in the oil

cooler fins with a brush or blower.

Important It is preferable to blow dirt out, rather than

washing it out. If water is used, keep it away from

electrical items and hydraulic valves. Do not use a high-pressure washer. High-pressure washing can damage the electrical system and hydraulic valves or deplete

Key Switch

Loader Arm/Attachment Tilt Lever

The key switch, used to start and stop the engine, has three positions: off, run, and start.

To start the engine, rotate the key to the start position. Release the key when engine starts and it will move automatically to the run position.

To stop the engine, rotate the key to the off position.

Throttle Lever

Move the control forward to increase the engine speed and rearward to decrease speed.

Choke Lever

Before starting a cold engine, move the choke lever forward. After the engine starts, regulate the choke to keep the engine running smoothly. As soon as possible, move the choke lever all the way rearward.

Note: A warm engine requires little or no choking.

Reference Bar

When driving the traction unit, use the reference bar as a handle and a leverage point for controlling the traction control and the auxiliary hydraulics lever. To ensure smooth, controlled operation, do not take both hands off of the reference bar while operating the traction unit.

Traction Control

To move forward, move the traction control forward. To move rearward, move the traction control rearward (Fig. 9).

To tilt the attachment forward, slowly move the lever to the right (Fig. 10).

To tilt the attachment rearward, slowly move the lever to the left (Fig. 10).

To lower the loader arms, slowly move the lever forward (Fig. 10).

To raise the loader arms, slowly move the lever rearward (Fig. 10).

You can also push the lever fully forward into a detent position (Fig. 10) to release the loader arms so that the attachment rests on the ground. This allows attachments such as the leveler and the hydraulic blade to follow the contours of the ground (i.e., float) when grading.

m–4666

3. Tilt the attachment rearward

4. Tilt the attachment forward

5. Detent (Float) position

To turn, rotate the traction control in the desired direction (Fig. 9).

The farther you move the traction control in any direction, the faster the traction unit will move in that direction.

To stop, release the traction control.

m–4664

Figure 9

By moving the lever to an intermediate position (such as, forward and left), you can move the loader arms and tilt the attachment at the same time.

Loader Valve Lock

The loader valve lock secures the loader arm/attachment tilt lever so that you cannot push it forward. This helps to ensure that no one will accidentally lower the loader arms during maintenance. Secure the loader arms with the lock anytime you need to stop the machine with the loader arms raised.

To set the lock, lift up on it so it clears the hole in the control panel and swing it to the left in front of the loader arm lever, pushing it down into the locked position (Fig. 11).

Auxiliary Hydraulics Lever

Note: The traction unit may roll slightly before the brakes engage in the drive sprocket.

m–5918

Figure 13

To release the brake, pull the lever rearward and right, out of the notch, and then push it forward.

To operate a hydraulic attachment in the forward direction, rotate the auxiliary hydraulics lever rearward and pull it down to the reference bar (Fig. 12, number 2).

To operate a hydraulic attachment in reverse direction, rotate the hydraulics lever rearward, then move it left into the upper slot (Fig. 12, number 3).

To operate the auxiliary hydraulics in the reverse direction using a detent position, rotate the lever rearward, then move it left into the middle slot (Fig. 12, Number 4). Only use the detent position for attachments that require it for operation, such as the Cement Bowl. To determine if an attachment requires the detent position, refer to the attachment operator’s manual.

If you release the lever while in either the forward position or upper reverse position, the lever will automatically return to the neutral position (Fig. 12, Number 1). If it is in the detent position, it will remain there until you pull it out of the slot.

Fuel Gauge

This gauge measures the amount of fuel in the fuel tank.

Hydraulic Oil Temperature Light

If the hydraulic oil gets too hot, this light illuminates and an audible alarm sounds. If this happens, stop the engine and allow the traction unit to cool.

Hour Meter/Tachometer

When the engine is off, the hour meter/tachometer displays the number of hours of operation that have been logged on the traction unit. When the engine is running, it displays the speed of the engine in revolutions per minute (rpm).

After 50 hours and then every 100 hours thereafter (that is at 150, 250, 350, etc.) the screen displays CHG OIL to remind you to change the engine oil. After every 100 hours, the screen displays SVC to remind you to perform the other maintenance procedures based on a 100, 200, or 400 hour schedule. These reminders come on starting three hours prior to the service interval time and flash at regular intervals for six hours.

Starting and Stopping the Engine

Parking Brake Lever
