Features
3-POINT OR PULL-TYPE
3-Point or Pull-Type Configurations
3-Point Hitch
Designed for deep tillage with strength and durability in mind. This Category III, 3-point hitch is integrated into a two-bar frame design with main members of heavy-duty, 6”x6” structural steel tubing.
Drawbar Pull-Hitch (Small Frame)
The optional drawbar pull-hitch lets you match tractors, not equipped with 3-point hitches, to the 4830 in-line ripper. Equipped with four 280/70 R 15 tires, the drawbar hitch provides excellent field flotation and depth control.
Drawbar Pull-Hitch (Large Frame)
The optional drawbar pull-hitch lets you match tractors, not equipped with 3-point hitches, to the 4830 in-line ripper. Four 280/70 R15 tires rear and (2) 280/70 R15 tires on front mounted gauge wheels.
SHANK MOUNTS
Shank Mounts to Match Your Field Conditions
Shear-Bolt
Rigid, shear-bolt mounts are an economical choice for soils where rocks or other obstacles are not a concern. Shear-bolt protection guards against shank damage from unexpected obstacles.
- Shear force: 10,000 pounds (approximate)
- 16” maximum shank working depth
- For non-rock conditions
Spring Reset
Recommended for field conditions where obstacles or rocks may be encountered. A 4”x4” welded tube provides strength.
- 2,500 pound point load
- 20” trip height
- 16” maximum shank working depth
- 36” underframe clearance
PathFind’R™
Exclusive pivoting design allows the shank to deflect up to 6 degrees on each side for a total of 12 degrees of movement.
- Basic spring reset design
- Makes deep ripping possible on contours or terraces
- Deflects impacts improving performance in rocky soils
- Smoother steering under full power with tracked tractors
- Reduces stress on implement frame and 3-point tractor hitch
- Not compatible with pull-type hitch
- 20” trip height
- 16” maximum shank working depth
- 36” underframe clearance
