Dominator Swing-Arm Stump Grinder Highlights
Adding to its professional line of land management tools, Reist introduced the Dominator series of Stump Grinders.
Reist’s swing arm model utilizes a 25″ rotor optimized to cut in one direction. Equipped with an adjustable flow control, the return speed of the arm can be adjusted to suit any operating condition or operators experience level.
The R25PS requires two remotes, one to adjust the height of the arm and one to swing it along its 55 degree arc. For tractors with only one remote, the R25PSV adds a valve on an ergonomically adjustable arm to control the hydraulic functions. To add a rear hydraulic function to your tractor, or to increase from one to two, check out the solutions from Summit Hydraulics and save 5% with code GWT!
Compatible with Cat I & II 3-Point Hitches, Dominator Stump Grinders are also compatible with Quick Hitches. The frame incorporates two pads which provide firm footing on uneven ground eliminating deflection of the frame.
See the grinder in action in this video.
Gear Box
Three Point Hitch swing type grinders utilize 1:1.9 ration gear box accelerating the flange mounted rotor to 1,026 RPMs.
Rotor
The uniquely shaped rotor is flange mounted to the drive line. This allows for easy removal of the rotor should it be required for maintenance.
Carbide Teeth
Dominator stump grinders use Wearsharp® teeth. The round design of the tooth and a triangular base allows it to be indexed 3 times for extended life.
HDPE Deflector
Made with high density polyethylene, the deflector stands up to abuse regardless of the air temperature all while containing debris from the stump.
Cutting Depth Gauge
An easy to read gauge helps operators determine the cutting depth.
Hydraulic Valve
The addition of an optional valve on an ergonomically adjustable arm, provides both lift and swing functions for tractors with one hydraulic remote (so two remotes are required for R25PSS, but only one remote required for the R25PSV).
