Section 6: Operating Procedures

! WARNING ! WARNING

Land Pride

The following operating procedures must be carefully read and fully understood. You are the tractor operator and are therefore responsible for the safe operation of this unit. All other persons must be cleared of the area. Cutter operation must be stopped when in the vicinity of other persons.

11.After attachment to the tractor, carefully raise and lower the cutter to ensure that the drawbar, tires, and other equipment on the tractor do not contact the cutter frame or PTO shaft.

12.Check all hoses and wires to be sure that they will not contact the PTO shaft. PTO guards must be in good condition and in place.

13.When the deck is in the transport position, and the PTO disengaged, check to be sure the blades are not locked (overlapped) together. The deck safety chain must be engaged in the deck hook provided.

14.Check blades for sharpness and ensure that both blade bolts as well as the center blade carrier hub nut are tight. Check tractor safety equipment - particularly the ROPS (Roll Over Protective Structure) and the operator safety screen to be sure both are in good working condition. Wear your safety glasses.

15.Remove and stow the deck safety chain just prior to cutting. Adjust lower 3-point links such that the PTO shaft is approximately level. Extend the cutters parallel arms out and position the deck flat on the ground.

16.Increase tractor throttle to approximately 500 RPM and slowly engage the PTO. Initial start-up vibration is normal, but should stop after a few revolutions of the blade carrier. If vibration continues, stop PTO rotation. Wait for the blade carrier to come to a complete stop before dismounting from the tractor, then check the blades to be sure they are not locked together.

17.Once the cutter is running smooth increase tractor throttle to provide for 540 PTO RPM.

IMPORTANT: If a 1000 RPM tractor PTO is being used, engine RPM MUST be reduced to limit PTO RPM to 540. Excessive engine speed will cause damage to the speed increaser and other power train components.

18.Position the cutter deck for best operator visibility. This is normally with the arms extended to approximately 3/4 of full extension. Adjust deck attitude and height. Optimum ground speed will depend on the density of the material being cut, operator awareness, and (in some cases) terrain. If in doubt, reduce tractor ground speed to a comfortable level.

Do not operate this cutter under any terrain conditions that would place the tractor at an angle exceeding 30 degrees either front-to-rear or left-to-right. Ensure that adequate ballast weights are provided on both the front of the tractor and left of the tractor and left hand side of cutter to assure tractor stability. See Figure 6-1.

Breakaway Operations

This cutter is designed for breakaway of the cutter head and parallel arms in the event the cutter head contacts an immovable object or irregular terrain during forward tractor movement. The “breakaway” will prevent structural damage to the cutter head, parallel arms, and mainframe in the event of such contact. See Figure 6-2.

Upon breakaway, the cutter head must be reset to the original "home" position before normal cutting operations can be resumed. Reset to the home position is accomplished somewhat differently depending on whether the cutter is equipped with the standard tension bolt or the optional breakaway (hydraulic) cylinder.

Tension Bolt

1.Raise the arms and deck upward to clear any obstacles located behind the cutter deck.

2.Slowly back the tractor and cutter away from those obstacles that would interfere with rotating the deck and arms back to the “home” position.

!WARNING

Shut off PTO power, put the tractor in park and wait for the blades to stop rotating before dismounting from the tractor.
