Ripping
`
1.1. Multishank Ripper
2.1. Packed Soil, Hardpan, Clay, Shale or Cemented Gravel
3.1. Rock with Fractures, Faults and Planes of Weakness
4.1. Solid Rock, Granite, and Hard Material that is Difficult to Rip

Use FIRST gear for ripping operations. Use additional shanks instead of increasing the speed.

Use the decelerator in order to match the drawbar pull to the available traction. Use the decelerator in order to match the drawbar pull to the ground conditions. Also, use the decelerator in order to prevent spinning the track.

Rip the ground as deep as possible. Sometimes, you may rip at partial depth. You can remove the material in natural layers.

The sizing of the material is controlled by the depth of the pass and by the width of the pass.


NOTICE

Do not turn or back the machine while shanks are in the ground. Twisting strain on the shanks and tips may cause failure.


Multishank Ripper

The multishank ripper is intended for high production. Use the multishank ripper in hard, packed soil and loosened, embedded rock. The multishank ripper is for use in material that can be ripped with AT LEAST two shanks. Use the multishank ripper with a single center shank less than 20 percent of the time.

The multishank ripper is NOT intended for high production in rock with a single center shank.

A single shank ripper in an outside pocket of the ripper is NOT recommended. If necessary, locate the shank in the highest position. Operate the machine at reduced speed. The frame of the ripper is not designed for ripping with a single outside shank at full horsepower.

The multishank ripper is NOT intended for ripping in deep applications. Only use rippers of the specified length.

If deep ripping is required, use a single shank ripper.

Packed Soil, Hardpan, Clay, Shale or Cemented Gravel



Illustration 1g00040571
Multishank ripper with three shanks

Three shanks work well in these materials. Use the greatest possible number of shanks to break the material to the desired size. The number of shanks should not cause the machine to stall.

Rock with Fractures, Faults and Planes of Weakness



Illustration 2g00040576
Multishank ripper with two shanks

Use two shanks so that the rocks break out in small pieces, and so the machine can manage the job easily. When the machine begins to stall, use only the center shank. If the tracks spin, use only the center shank.

Solid Rock, Granite, and Hard Material that is Difficult to Rip

Multishank ripper with one shank

Use one shank in material that is difficult to rip or material that tends to break out in large slabs or pieces.
