You can find additional safety information where needed throughout this Operator’s Manual.

Slope Safety

  • Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. An empty attachment makes the rear of the machine the heavy end, and a full attachment makes the front of the machine the heavy end. Most other attachments make the front of machine the heavy end.

  • Keep the attachment in the lowered position when on slopes. Raising the attachment on a slope affects the stability of the machine.

  • Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope or uneven terrain requires extra caution.

  • Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.

  • Slow down and use extra care on hillsides. Ground conditions can affect the stability of the machine.

  • Avoid starting or stopping on a slope. If the machine 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 machine uphill.

  • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.

  • If you feel uneasy operating the machine on a slope, do not do it.

  • Watch for holes, ruts, or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.

  • Use caution when operating on wet surfaces. Reduced traction could cause sliding.

  • Do not operate the machine near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel or track goes over the edge or the edge caves in. Maintain a safe distance between the machine and any hazard.

  • Do not remove or add attachments on a slope.

  • Do not park the machine on a hillside or slope.

  • Do not pull a trailer on any slope.

Trench Filler Safety

  • Stay in the operator’s position behind the control panel while operating the trench filler.

  • Do not overload the machine capacity by attempting to backfill too fast.

  • Disengage power to the auger/impeller when the trench filler is transported or not in use.

Maintenance and Storage Safety

  • Check fasteners at frequent intervals for proper tightness to ensure that the equipment is in safe operating condition.

  • Refer to the Operator’s Manual for important details if you store the attachment for an extended period of time

  • Maintain or replace safety and instruction labels, as necessary.

To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.


Installing and Removing the Attachment

Refer to the Operator’s Manual for the traction unit for the installation and removal procedure.

Important: Before installing the attachment, position the machine on a level surface, ensure that the mount plates are free of any dirt or debris, and ensure that the pins rotate freely. If the pins do not rotate freely, grease them.

Note: Always use the traction unit to lift and move the attachment.


If you do not fully seat the quick-attach pins through the attachment mount plate, the attachment could fall off the machine, crushing you or bystanders.

Ensure that the quick-attach pins are fully seated in the attachment mount plate.


Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury; otherwise, gangrene may result.

  • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.

  • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.

  • Use cardboard or paper to find hydraulic leaks; never use your hands.


Hydraulic couplers, hydraulic lines/valves, and hydraulic fluid may be hot. If you contact hot components, you may be burned.

  • Wear gloves when operating the hydraulic couplers.

  • Allow the machine to cool before touching hydraulic components.

  • Do not touch hydraulic fluid spills.

Filling a Trench

  1. Start the machine.

  2. Pull the auxiliary-hydraulics lever to the reference bar to engage the trench filler.

  3. Slowly lower the trench filler to the ground so that the auger is just above the ground.

    Note: For best results, start with the float rollers centered in the float guide.

  4. Slowly move the traction unit forward to fill the trench.

    Note: When you move too fast, the trench filler stalls. If it stalls, raise it slightly, slowly drive rearward, then resume moving forward.

  5. When finished, stop the trench filler by releasing the auxiliary-hydraulics lever.

Transporting the Attachment on a Trailer

  1. Place the attachment on a trailer or truck capable of carrying it.

  2. Securely tie the attachment to the trailer or truck using tie straps appropriate for the weight of the attachment and for highway use.

Transport Position

When transporting the attachment, keep it as close to the ground as possible, no more than 15 cm (6 inches) above the lowest position. Tilt it rearward.


Operating Tips

  • Clean the area of trash, branches, and rocks before trench filling to prevent equipment damage.

  • For best trench filling, center the unit over the trench (Figure 5).

  • Always begin trench filling with the slowest ground speed possible. Increase the speed if conditions permit.

  • Always use full throttle (maximum engine speed) when trench filling.

  • Never transport the trench filler with the loader arms raised.

  • When trench filling, the auger should just clear the original ground surface to obtain maximum soil deposit into the trench.

  • Periodically check to ensure that the rollers on the trench filler float are operating properly.

  • When finished, compact the material over the trench to prepare it for grading.
