MillerGrinder Pro-75T

The ultimate grinder for 45 to 90 HP tractors

This mid-sized PTO shaft-driven attachment stump grinder is designed to connect to 45 to 90 HP tractors using a 3-point hitch. The PRO75T stump grinder is ideal for serious stump grinding applications, where tractor limitations require a PTO speed of 540 RPM. Applications include stump grinding contractors, tree service operations, lot clearing, land clearing, farm use, parks and municipalities. Note the Pro-75T has the same size cutting wheel and virtually the same weight as the 100T. The key difference is the lower RPM.

Features Benefits
Oversized Constant Velocity PTO Driveline Maximizes transmission of power from tractor to cutting wheel and provides smooth, long-lasting performance and dependability with less wear and tear on the tractor.
Patented 6-way (X-Y-Z) hydraulic positioning of the cutting blade:
up/down, tele in/tele out, swing left/swing right.
Allows operator to plant the grinder down firmly on its backfill blade, position it in all six directions and grind an average 36”stump without having to reposition the machine, greatly increasing productivity and reducing lawn damage.
Very heavy unit weights with oversize components throughout:
Pro-75T         1,720 lbs
Pro-100T       1,730 lbs
Pro-150T       2,340 lbs
Heavy weight increases stability during cutting.
True professional-grade quality with at least twice the durability of typical attachment-type grinders.
26” (for 75T and 100T) or 30” (150T) diameter wheel supported by tapered roller bearings in a sealed oil bath Very low maintenance, enabling very smooth, relatively quiet operation
Perfectly weighted 1.25” (for 75T and 100T) or 1.5” (150T) Blanchard ground wheel thickness with .01” parallelism and flatness tolerances Eliminates bounce and runs true for a very smooth cutting action without vibration.
Oversize HD cast iron gear box with tapered roller bearings running in a sealed oil bath. Smooth operation and quiet running with excellent service life.
Integral backfill blade. Allows you to clean and level the site without changing attachments. Effectively contains chips for easy clean up.
Swing and lift functions pivot on hardened and bushed 2.00” diameter pins with composite bushings. 60% greater wear surface (compared to typical 1.25”) pins, enabling exceptionally long maintenance freeservice life.
High durability carbide teeth made in the USA. Requires replacing less often, reducing maintenance costs.
Oversize components are engineered for optimal oil flow ‎to keep oil temperatures low. Eliminates the need for an oil cooler and greatly increases the life of all hydraulic components.
