3. With the height adjusting screws adjusted with the mower at its lowest. position, rotate the side blades and measure from the outside tips to the floor. This should measure the same on both sides. If one side is lower, the clevis on the front mount on that side should be lengthened slightly. With the adjustment properly made, it will aid the cutting height adjusting screws to keep the unit level.

4.  Set mower to top of the cutting height adjustment. Use caution and see that the two adjusting screws at the roller hold the unit level.  They must be adjusted the same amount of turns each time the cutting height is changed.  Because of the linkage at the front mounting points, the mower will maintain the fore and aft adjustment.  Start the mowing operation with a high or long stubble. Lower the mower evenly to the desired cut.  If at first the cut is too high, the area can be rernowed.

OPERATION

1. Set mower to desired height of cut by turning the adjusting screw handles counter -clockwise to lower the cut, and clockwise to raise the cut. Turn each handle an equal number of turns to insure level operation.

2. Start the tractor engine with the power take-off in the disengaged position, and lower the mower to cutting position by releasing the tractor lift lever .

3. Engage the power take-off to set the mower blades in operation; engage the tractor clutch, and proceed with mowing.

4. To transport the mower, disengage the power takeoff to stop blades. Raise the mower above the surface by pushing the tractor lift lever to forward locked position.

BELT TENSION

The drive belt tension is regulated by a spring-loaded idler. The spring tension is set at the factory and should require no adjustment.

NOTE: The cross drive belt and the blade drive belt are a super combine type belt, and are designed and manufactured to provide long and satisfactory service. Because of the special design of these belts, it is urged that you replace them only with genuine replacement belts ordered from your dealer.

  CAUTION: It is the responsibility of the operator to see that the area where the mower will be used is free of all types of foreign material. This includes wire, rope, rags, sticks, bottles, cans, pipe, rocks, etc. These represent potential dangers to mower, operator, and spectators; as well as having a dulling effect on the mower bladed.

Always guard for obstacles when mowing, and never leave mower running while unattended.
