If additional leverage is needed, you can doze a small ramp near the base of the tree. The ramp allows the machine to make higher contact on the tree. Push the tree in the direction of the intended fall. Advance cautiously. The ball of the root may hang up under the bulldozer blade. This movement could drag the machine off the ramp.Stump Removal

Stump Removal - Make sure that roots are cut or loosened. Remove the stump by pushing or digging.Ripping
Use FIRST speed range for ripping operations. Use additional shanks instead of increasing the speed or higher speed ranges.Use the decelerator in order to match the drawbar pull. 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. If the material is loaded with a wheel dozer, the size of the material should be smaller. Finally, the material should be smaller if the material is loaded into a scraper.
Do not turn or back the machine while shanks are in the ground. Twisting strain on the shanks and tips may cause failure.
Inspect the ripper tips frequently for excessive wear.
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 ripper shank 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 shanks of the specified length.Use a single shank ripper when deep ripping is required.Packed Soil, Hardpan, Clay, Shale, or Cemented Gravel

Multishank ripper with three shanksThree shanks work well in these materials. Use the greatest possible number of shanks to break the material to the desired size. However, the number of shanks that are used should not cause the machine to stall.Rock with Fractures, Faults, and Planes of Weakness

Multishank ripper with two shanksThe use of two shanks will cause the rocks to break out in smaller pieces. , Then, 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.Single Shank Ripper (Solid Rock, Granite, or Hard Spots)
