Safety

Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and those in the traction unit Operator's Manual. Always pay attention to the safety alert symbol, which means Caution, Warning, or Danger—personal safety instruction. Failure to comply with the instruction may result in personal injury or death.

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 could void the product warranty.

Danger

Contact with rotating tines may cause injury, cutting hands, feet, or other body parts.

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

  • Keep your hands, feet, and any other part of your body or clothing away from rotating parts.

  • Before adjusting, cleaning, repairing and inspecting the tiller, lower the tiller and loader arms to the ground, turn the key to the OFF position, and remove the key from the ignition switch.

Warning

There may be buried power, gas, and/or, telephone lines in the area needing tilling and shock or explosion may occur.

Have the property or area to be tilled marked for buried lines.

Warning

Tines can throw dirt, debris, and small rocks resulting in injury.

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

  • Keep all bystanders away from the work area.

Warning

When the engine is off, attachments in the raised position can gradually lower and this may result in someone nearby getting pinned or injured.

Always lower the attachment lift each time you shut off the traction unit.

Warning

If you do not fully seat the attachment locking pins in the attachment mount plate holes, the attachment could fall off of the traction unit, causing severe injury.

  • Ensure that you fully seat the attachment locking pins through the holes in the attachment mount plate before lifting the attachment.

  • Ensure that the attachment mount plate is free of any dirt or debris that may hinder the connection of the traction unit to the attachment.

  • Refer to your traction unit Operator's Manual for detailed information on safely connecting an attachment to your traction unit.

Caution

Hydraulic couplers, hydraulic lines/valves, and hydraulic fluid may be hot and can burn you if you touch them.

  • Wear gloves when operating the hydraulic couplers.

  • Allow the traction unit to cool before touching hydraulic components.

  • Do not touch hydraulic fluid spills.

Stability Ratings

To determine the degree of slope you can traverse with the attachment installed on a traction unit, find the stability rating for the hill position you want to travel in the appropriate table below, then find the degree of slope for the same rating and hill position in the Stability Data section of the traction unit Operator's Manual.

Warning

Exceeding the maximum recommended slope can cause the traction unit to tip, crushing you or bystanders.

Do not drive the traction unit on a slope steeper than the maximum recommended slope, as determined in the following tables and the traction unit Operator's Manual.

Important: If your traction unit has wheels, do not use the counterweight on the platform while using the attachment, or the traction unit will become less stable in the front and side uphill positions.

Operation

Refer to your traction unit Operator’s Manual for more information on installing and removing attachments on your traction unit.

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

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

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

  • Always use full throttle (maximum engine speed).

  • 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.

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