Preparation and Setup
Hitching Tractor to Sub-Soiler
Crushing Hazard:
Do not stand or place any part of your body between sub-
soiler and moving tractor. You may be severely injured or
killed by being crushed between the tractor and sub-soiler.
Stop tractor engine and set parking brake before attaching
cables and hoses.
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin
causing serious injury. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
Hitching with 3-Point
1. The sub-soiler is designed to use either Category II or III
tractors. This implement is factory set for Category III
tractors. To change to Category II, you will need a
Category II Ripper hitch pin kit P/N 596-060A. See your
Great Plains dealer to order kit.
2. In addition, the following bushings (not supplied by Great
Plains) may be needed to fit your quick hitch or tractor’s
3-point arms:

before lifting the implement. Adjust the top 3-point link
so that the frame is at desired tip depth, parallel with the
ground.
4. Set the tractor 3-point draft control in the float position.
5. Raise the tractor 3-point arms as needed and pin lower
arms to implement.
6. See drawing for correct pins and hole positions for
Category II.

pin (1) in middle hole.
