One example provides a grinding positioning plate for a reel-type mower unit including a cutting reel having a rotational axis. The grinding positioning plate includes a main body including a pivot element having a pivot axis, and at least one pair of clamping assemblies, each clamping assembly to clamp to a corresponding mounting flange of the reel-type mower unit to mount the main body to reel-type mower unit such that the pivot axis is in parallel with the rotational axis and at a known horizontal distance from the rotational axis.

Grinding positioning plate for reel-type mower unit

A mower reel grinding system a plurality of mower unit types, including a grinding wheel shaft, the grinding wheel shaft at a fixed position in an x-y plane. A mounting plate includes a number of predetermined fixed mounting positions on the mounting plate, each predetermined fixed mounting positions corresponding to at least one type of mower unit of the plurality of mower unit types, a mounting bracket to receive a mower unit, the mounting bracket selectively moveable to the predetermined fixed position corresponding to the mower unit type to be received thereby, and a pivot point about which the mounting plate rotates to adjust a position of the mounting bracket in the x-y plane relative to the grinding wheel shaft.

Mower reel grinding system with rotating rear brackets

A mower reel grinding apparatus for a plurality of type of mower units, the apparatus including an enclosure including a plurality of predetermined fixed positions, each predetermined fixed position corresponding to at least one type of mower unit of the plurality of mower units, a grinding wheel, and a bracket to receive and releasably secure to a predetermined location on any one of the plurality of types of mower units, the bracket moveable to the predetermined fixed position corresponding to the type of mower unit releasably secured thereto such that a cutting reel of the mower unit is positioned at a desired position relative to the grinding wheel.

Mower reel grinding system using predetermined bracket positions

A mower reel grinding apparatus including at least one bracket moveable in a horizontal plane along a positioning axis to any one of a number of predetermined positions and configured to releasably secure to a pivot mechanism of a plurality of types of mower units, the pivot mechanism having a pivot axis, each type of mower unit including a cutting reel positioned at a known location relative to the pivot axis, and each of the predetermined positions corresponding to at least one type of mower unit of the plurality of types of mower units, wherein the at least one bracket is moved to the predetermined position corresponding to the type of mower unit secured thereto such that the cutting reel is positioned at a desired grinding position along the positioning axis when the pivot axis is secured to the bracket.

A device and method for sharpening a mower blade are provided, in which a mounting device for mounting a rotary blade having two opposite cutting edges to be sharpened, wherein the mounting device is capable of positioning the blade in a first fixed state and a second, axially pivoting state. One or more grinding head assemblies are each positioned on an opposite end of the blade, wherein the grinding head assemblies respectively grind the two opposite cutting edges to be sharpened. A control system controls movement of the two grinding head assemblies. The mounting device positions the blade in the first fixed state to enable the two grinding head assemblies to grind the cutting edges in a direction substantially parallel to the cutting edges of the blade to perform a straight grind, and then may position the blade in the second axially pivoting state to enable the blade to pivot around its blade rotation axis away from the grinding head assemblies upon completion of the straight grind, thereby forming a curve at the end of each cutting edge. The mounting assembly also holds the blade in a third, freely rotating state in which the blade may substantially freely rotate around its blade rotation axis to enable balancing of the blade after sharpening.

Rotary mower blade sharpener having movable griding wheels

The present invention is a device for relief grinding a blade having a radially outer edge of an elongated length and first and second faces, with the first and second faces extending generally radially from a reel axis. The device includes a rotatable grinding shaft, a grinding wheel, a grinding wheel guide assembly, a guide finger, and a first non-sliding stabilizer.
