460 Automated Rotary Blade Grinder

Foley Company Logo Final.jpg

Take a look at the most innovative product for the Turfcare Industry: If you’re looking for a grinder that will elevate performance, increase cut quality, and raise production, then you need to see the new 460 Automated Rotary Blade Grinder.


Nothing else on the market addresses the need for a high volume, productive commercial blade grinder in the lawn/ garden and golf industries.


While grinding is recommended every eight to ten hours of use, the 460 minimizes the multiple issues associated with dull rotary blades: more stress on hydraulics, added strain on your engine, and blades aren’t sharpened regularly.


Increase safety and production
The 460’s enclosure system for dust and noise control features two grinding heads, automated infeed cycles, and a built in blade balancing system that makes the process safer and more productive than ever thought possible. Another innovative first from Foley United.

OEM END of GRIND BLEND RADIUS: A key feature of the 460 is an ability to produce the blend radius that is engineered into all new blades. This unique patent pending feature minimizes blade stress that can be common with other rotary blade grinding systems, and produces a blend-out that is consistent, safe, and effective.

Built-in Blade Balancing System

BUILT-IN BLADE BALANCING SYSTEM: This one-and-only blade balancing design features a knob release that allows for the heavy end of the blade to drop, and when relocked, grinding more on the heavy end is easily done to produce a properly balanced blade.

Height Adjustment Feature

HEIGHT ADJUSTMENT FEATURE: This design allows the grinding heads to be adjusted to provide clearance with the various airfoil “lift“ designs on the rotary blades.

Center Hole Quick Connect Cone

CENTER HOLE “Quick Connect Cone”: With the push of a button, a coneshaped mount slides on a threaded stud to securely mount the blade’s center hole in the mounting fixture.

Dual Grinding Head Design

DUAL GRINDING HEAD DESIGN: Unique design allows for both ends of the blade to be ground evenly and simultaneously.

Proximity Switches

PROXIMITY SWITCHES: Coated, durable traverse proximity switches are easily positioned to control the length of travel for the grind area. These allow for the fast repetitive set-up for identical blades, producing a perfect consistent grind each and every time.

Blade Radius Relief Slide Bar

BLEND RADIUS RELIEF SLIDE BAR: The measuring decal associated with the relief slide bar makes the set-up process extremely fast. This is one of the many features that makes the repeatability of set-up easy, and reduces the amount of time to change from different blade types to mere seconds.
