Mower reel grinding system using predetermined bracket positions

Abstract

A mower reel grinding apparatus for a plurality of types of mower units, the apparatus including a grinding wheel having a grinding wheel axis, and an enclosure including a table having a plurality of integral mounting channels. Each mounting channel is at a predetermined fixed position relative to the grinding wheel axis and each corresponds to at least one type of mower unit of the plurality of mower unit types, each mounting channel to receive a pivot element of one of the corresponding mower unit types such that when the pivot element is seated in the mounting channel a cutting reel of the mower unit is positioned at a desired position relative to the grinding wheel axis.

What is claimed is: 
     
         1 . A mower reel grinding apparatus for a plurality of types of mower units, the apparatus comprising:
 a grinding wheel having a grinding wheel axis;   an enclosure including a table having a plurality of integral mounting channels, each mounting channel at a predetermined fixed position relative to the grinding wheel axis and each corresponding to at least one type of mower unit of the plurality of mower unit types, each mounting channel to receive a pivot element of one of the corresponding mower unit types such that when the pivot element is seated in the mounting channel a cutting reel of the mower unit is positioned at a desired position relative to the grinding wheel axis.   
     
     
         2 . The mower reel grinding apparatus of  claim 1 , each of the plurality of integral mounting channels extending in a longitudinal direction which is parallel to the grinding wheel shaft. 
     
     
         3 . The mower reel grinding apparatus of  claim 1 , including;
 a slot extending through the mounting channels, the slot extending perpendicularly to a longitudinal direction of the mounting channels; and   a clamping assembly moveable within the slot to any one of the mounting channels and to simultaneously releasably secure a mower unit within a mounting channel and to releasbly secure the clamping assembly to the enclosure.   
     
     
         4 . The mower reel grinding assembly of  claim 1 , wherein each of the mounting channels is v-shaped. 
     
     
         5 . The mower reel grinding assembly of  claim 1 , wherein each of the mounting channels it to receive a rear roller of a mower unit. 
     
     
         7 . A mower reel grinding apparatus comprising:
 a traverse base assembly including at least one guide rod;   a carriage to which a grinding wheel having a grinding wheel axis is mounted, the carriage and grinding wheel together moveable back and forth along the at least one guide rod in the direction of the grinding wheel axis, the carriage including first and second mounting pins to receive a linear measuring gage, the second mounting pin at an angle to a vertical line extending through the first mounting pin.   
     
     
         8 . The mower reel grinding apparatus of  claim 1 , the first mounting pin to position the linear measuring gage to measure a position of a perimeter of a cutting reel of a mower unit when mounted to the mower reel grinding apparatus and the second pin to position the linear measuring gage to measure a position of a rotational shaft of the cutting reel.
