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.

Removing the Roller

To use the cultivator as a tiller without the grader or roller, or to perform various adjustments and maintenance procedures, remove the roller and grader as follows:

  1. Park the machine on a level surface, lower the attachment, tilt the attachment to raise the roller off of the ground, and engage the parking brake (if equipped).

  2. Shut off the engine and remove the key

  3. Remove the drift pins from the arms of the cultivator (Figure 5).

    g030948

g286182

Operating Tips

  • Inspect the area where the cultivator is to be used and remove all objects such as large rocks, trash, and branches before cultivating to prevent equipment damage.

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

  • Always use full throttle (maximum engine speed).

  • Cultivate in long, straight passes. Turning with the tines lowered causes equipment and property damage.

  • If a rock or other obstruction goes into the tines, disengage the hydraulics and drive the traction unit forward until the obstruction is dislodged.

  • If you are using a traction unit with a flow divider (some wheeled units have flow dividers; refer to your traction unit Operator’s Manual), you can use the flow divider to achieve the optimal rotor and ground speed for your soil conditions as follows:

    1. Set the flow divider to the 9 o’clock position and the speed selector to the turtle position.

    2. Pull the auxiliary hydraulics lever to the operator grip to start the cultivator.

    3. Move the flow divider lever while moving the traction unit rearward until the cultivation results are ideal.

Maintenance

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

Caution

If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders.
