DRIVELINE ADJUSTMENT

BB840XP (PULL-TYPE)

With the cutting height established, adjust the driveline carrier bearings in the H-frames so that the front drive- line is parallel to the ground with cutter in cutting posi- tion.

TRANSPORTING BB840XP (PULL-TYPE)

DP1

Figure 10. Transport Lock Operation

1.Always transport with cutter in raised, locked position.

2.Raise cutter with hydraulic cylinder to max height.

3.Rotate transport lock into position over cylinder rod. See Figure 10.

4.Lower cylinder against transport lock.

5.To lower cutter for operation, extend hydraulic cylinder. Rotate transport lock back away from cylinder rod.

6.Lower cutter to desired cutting height.

OPERATING TECHNIQUE

1.Power for operating the cutter is supplied by the tractor PTO. Operate PTO at 540 rpm. Know how to stop the tractor and cutter quickly in an emergency.

2.Engage PTO at a low engine rpm to minimize stress on the drive system and gearbox. With PTO engaged, raise PTO speed to 540 rpm and maintain throughout cutting operation.

Gearbox protection is provided by a slip clutch with replacement fiber disc. The slip clutch is designed to slip when excessive torsional loads occur.

3.Move slowly into material. Adjust tractor ground speed to provide a clean cut without lugging the tractor engine. Use a slow ground speed for better shredding.

Proper ground speed will depend on the terrain and the material’s height, type, and density.

Normally, ground speed will range from 2 to 5 mph. Tall, dense material should be cut at a low speed; thin, medium-height material can be cut at a faster ground speed.

4.Always operate tractor PTO at 540 rpm to maintain proper blade speed and to produce a clean cut.

5.Under certain conditions tractor tires may roll down some grass and prevent cutting at the same height as the surrounding area. When this occurs, reduce your ground speed but maintain PTO at 540 rpm. The lower ground speed will permit grass to rebound partially.

SHREDDING MATERIAL

For shredding, set the cutter lower at rear. Determine how much lower to set the rear by experimenting in dif- ferent situations.

STORAGE

Mounted Cutters

Disconnect cutter driveshaft and secure up off ground. Raise cutter with 3-point hitch. Place blocks under cutter side skids. Lower cutter onto blocks. Disconnect cutter from tractor 3-point hitch and carefully drive tractor away from cutter.

Keep children and bystanders away from stor- age area.

BB840XP (Pull-Type)

Raise cutter and block securely. Block wheels and raise tongue with jack. Disconnect hydraulic lines to optional cylinder. Disconnect driveline and secure up off the ground.
