If you need to add rear weight, contact your authorized Toro distributor for additional weights and refer to the following installation procedures:
Loosen the hardware that secures the weight-lock rod to the bumper.
Add the required amount of weights.
Tighten the weight-lock-rod hardware to secure the weight to the bumper.
Refer to your authorized Toro distributor to order the following parts:
Part Name | Quantity | Part Number |
Screw (3/8 x 3-1/2 inches) | 2 | 116-4701 |
Washer | 2 | 125-9676 |
Nut (3/8 inch) | 2 | 104-8301 |
Use the hardware to secure the weights to the bumper (Figure 18).
Perform this procedure only if you are installing an attachment other than the standard rotary cutting units (e.g., snowthrower, blade, or flail).
You can change the hydraulic pressure used to transfer the weight of the attachment to the traction unit by adjusting the weight-transfer valve of the hydraulic manifold. For best performance, adjust the weight-transfer valve so that any bouncing motion of the attachment is minimal over uneven terrain, but also adjust the valve so that the attachment does not ride heavily over flat terrain or lower too quickly.
To improve the contour-tracking performance of the attachment as you operate the machine over uneven terrain, decrease the weight-transfer (hydraulic) pressure at the hydraulic manifold.
Note: If the attachment casters or the leading edge of the snowthrower float above the ground, the hydraulic pressure of the weight transfer valve is too high.
When you are cutting flat turf, when the cutting unit is scalping the grass, if the quality of cut is uneven from side to side, or the leading edge of a snowthrower is scraping too heavily, increase the weight-transfer pressure at the hydraulic manifold.
Note: Increasing weight-transfer pressure also transfers the weight from the attachment to the wheels of the traction unit, thereby improving the traction of the traction unit.
Adjust the weight-transfer pressure as follows:
Operate the machine for 10 minutes.
Note: This will warm the hydraulic fluid.
Park the machine on a level surface, lower the attachment, engage the parking brake, shut off the engine, and remove the key from the switch.
Locate the lift manifold from under the machine (Figure 19).
Connect a pressure gauge to the test port (labeled G1; refer to Figure 20).
At the side of the lift manifold, remove the cap from the test port (labeled G1; refer to Figure 20).
Loosen the jam nut at the end of the weight-transfer spool (labeled LC; refer to Figure 20).
Start the engine, set the throttle to HIGH IDLE.
Use a hex-socket wrench to adjust the counterbalance valve of the weight-transfer spool until the gauge indicates the desired pressure; refer to the following table for the recommended pressure setting for the attachment.
Rotate the adjusting screw clockwise to increase the pressure.
Rotate the adjusting screw counterclockwise to decrease the pressure.
Attachment | Weight-Transfer Pressure |
---|---|
Rotary cutting unit | 1,724 kPa (250 psi) |
Flail Mower (Model Number 02835) | 1,379 kPa (200 psi) |

Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.
Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.
Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.
Do not carry passengers on the machine and keep bystanders and children out of the operating area.
Operate the machine only in good visibility to avoid holes or hidden hazards.
Avoid mowing on wet grass. Reduced traction could cause the machine to slide.
Keep your hands and feet away from rotating parts. Keep clear of the discharge opening.
Look behind and down before backing up to be sure of a clear path.
Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
Stop the blades whenever you are not mowing.
Stop the machine, remove the key, and wait for all moving parts to stop before inspecting the attachment after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.
Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.
Disengage the drive to the cutting unit, shut off the engine, remove the key, and wait for all movement to stop before adjusting the height of cut (unless you can adjust it from the operating position).
Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.
Never leave a running machine unattended.
Before you leave the operator’s position, do the following:
Park the machine on a level surface.
Disengage the power takeoff and lower the attachments.
Engage the parking brake.
Shut off the engine and remove the key.
Wait for all movement to stop.
Operate the machine only in good visibility. Do not operate the machine when there is the risk of lightning.
Do not use the machine as a towing vehicle.

Replace damaged ROPS components. Do not repair or alter them.
A cab installed by Toro is a roll bar.
Always wear your seat belt.
Keep a folding roll bar in the raised and locked position, and wear your seat belt when operating the machine with the roll bar in the raised position.
Lower a folding roll bar temporarily only when necessary. Do not wear the seat belt when the roll bar is folded down.
Be aware that there is no rollover protection when a folded roll bar is in the down position.
Check the area that you will be mowing and never fold down a folding roll bar in areas where there are slopes, drop-offs, or water.
Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.
Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.
Review the slope instructions listed below for operating the machine on slopes and to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.
Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.
Do not operate a machine under any conditions where traction, steering, or stability is in question.
Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.
Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.
Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.
Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.
If possible, keep the cutting unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.
Use extreme caution with grass-collection systems or other attachments. These can change the stability of the machine and cause a loss of control.
The diesel-particulate filter (DPF) removes soot from the engine exhaust.
The DPF regeneration process uses heat from the engine exhaust that is increased by the catalyst to reduce accumulated soot into ash.
To keep the DPF clean, remember the following:
Run the engine at full engine speed when possible to promote DPF self-cleaning.
Use the correct engine oil.
Minimize the amount of time that you idle the engine.
Use only ultra low sulfur diesel fuel.
Operate and maintain your machine with the function of the DPF in mind. Engine under load generally produces adequate exhaust temperature for DPF regeneration.
Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the DPF.
The exhaust temperature is hot (approximately 600°C (1,112°F) during DPF regeneration. Hot exhaust gas can harm you or other people.
Do not operate the engine in an enclosed area.
Ensure that there are no flammable materials around the exhaust system.
Ensure that the hot exhaust gas does not contact surfaces that may be damaged by heat.
Do not touch a hot exhaust system component.
Do not stand near or around the exhaust pipe of the machine.
