Grinding positioning plate for reel-type mower unit

A grinding positioning plate to selectively attach to reel-type mower units including a cutting reel having a rotational axis and first and second frame flanges disposed at opposite ends of the cutting reel including frame apertures for attaching the reel-type mower unit to a mower, the grinding positioning plate comprising:

• an elongated support body extending longitudinally between opposing first and second ends, the support body including:
• at least three mounting point sets spaced longitudinally apart on the elongated support body between the opposing first and second ends, each mounting point set comprising a plurality of pins extending from the support body and arranged to align with and be inserted into the frame apertures of a corresponding one of the first and second frame flanges to mount the elongated support body to the reel-type mower unit, wherein different pairs of mounting point sets correspond to different widths of reel-type mower units;
• and
• a pivot element supported from the elongated support body and having a pivot axis extending in parallel with the elongated support body and perpendicularly to the plurality of pins of the mounting point sets, the pivot element to serve as a clamping point for an automated grinding machine;
• and
• at least one pair of clamping assemblies, each clamping assembly to clamp to a different one of the first and second frame flanges to secure the elongated support body to the 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.
