Abstract
A reel type mower (2) has a rotatable cutting reel (4) and a cooperating bedknife (8). A control system (30) automatically positions the bedknife (8) relative to the cutting reel (4). An electrical potential is normally maintained between the bedknife (8) and reel (4). The control system (30) monitors this electrical potential and counts the number of times the electrical potential disappears during a predetermined time interval. If the counted value is different from the reference value, an actuator (32) turns an adjustment shaft (42) to change the position of bedknife (8) relative to reel (4).
