Failure to comply with these instructions may result in personal injury or death.

Slope Safety

  • Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. This attachment makes 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.

  • Evaluate the area to ensure that the ground is stable enough to support the machine.

  • Use caution when operating the machine near the following:

    • Drop-offs

    • Ditches

    • Embankments

    • Bodies of water

    The machine could suddenly roll over if a track or wheel 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.

Tiller Safety

  • For wheeled machines, do not use the counterweight on the traction unit when using the tiller.

  • Keep bystanders at least 15 m (50 ft) away from the machine.

  • Run the tiller so that debris is thrown away from the traction unit.

  • Keep away from the rotating tines while operating the tiller.

  • After striking a foreign object, shut off the engine, remove the key, thoroughly inspect the attachment for any damage, and repair the damage before starting and operating the attachment.

  • Always lower the attachment each time you shut off the machine or leave the operating position.

Attachments/Accessories

A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or authorized Toro distributor or go to www.Toro.com for a list of all approved attachments and accessories.

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.

Operation

Determine the left and right sides of the machine from the normal operating position.

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.

Warning

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.

Warning

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.

Caution

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.

Starting the Tiller

  1. Start the traction unit engine and set the throttle to HIGH IDLE.

  2. Engage the auxiliary hydraulics.

  3. Slowly lower the tiller to the ground.

  4. Move the traction unit forward or backward as desired.

    Note: For the rotor to operate effectively, rotate it in the same direction that the traction unit is moving. The direction of the rotor rotation is controlled by the traction unit hydraulic controls; refer to the following table.

    Important: Disengage the auxiliary hydraulics and wait for the rotor to stop completely before changing the rotor direction.

Operating Tips

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

  • Mow and remove tall grass and weeds before tilling to minimize grass and weeds wrapping around the rotor.

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

  • Always use full throttle (maximum engine speed).

  • If the rotor stalls, slow down the travel speed or decrease the rotor depth by raising the rotor

  • Do not till under wet conditions; soil stuck to the rotor and teeth decreases performance.

  • You may need to make multiple passes when working in sod or compacted soil.

  • Till in long, straight passes. Do not make turns while the tiller is in the ground, as equipment damage may result.

  • Avoid excessive tilling of the soil, as finely tilled soil does not absorb moisture easily and puddles of water may form.

  • When tilling hard packed, very dry, or virgin soil, raise the tiller so only the very top of the soil is penetrated. On succeeding passes the depth may be lowered.

  • Run the tiller so that the dirt is thrown away from you.

  • Wait for the tiller to stop before changing the rotation direction.

  • If a rock or other obstruction gets into the tiller tines, reverse the rotation direction to dislodge it.

Maintenance

Determine the left and right sides of the machine from the normal operating position.
