<p>A computer controlled all-in-one reel mower sharpener and roller alignment system can be rolled under a mower to be conditioned. No removal of the cutting unit is needed. A linear voltage displacement transducer (LVDT 715 or a mechanical dial indicator 7155 ; alternatively a friction wheel 7150 with a rotary encoder 7151 may be used, or any combination of sensors 715, 7155, 7151 ) or equivalent instructs the machinist how to align the front and rear rollers in parallel. A laser scanner or probe determines the location for the cutter, and then the machining head sharpens each blade automatically. A separate cutter sharpens the bed knife. Most all mowers can be conditioned based on the laser or probe calibration of the blade size. The laser or probe measures the height of cut by sensing the blade location.</p> |
