Abstract
A system adjusts the height-of-cut of a cutting reel unit. The system includes a cutting reel; a first frame supported on at least one support element that is supported on, and is movable along, the ground; and a second frame supporting the cutting reel. The system further includes an actuator that has a first portion connected to the first frame and a second portion connected to the second frame, wherein a distance between the first and second portions is adjustable. The actuator includes a motive mechanism that is activated to adjust the distance. The system can include at least one strut pivotally connected to the first frame and pivotally connected to the second frame on a second side of the second frame opposite to the first side. The strut extends between the first frame and the second frame. The strut defines the rotation of the second frame with respect to the first frame as the relative elevation of the second frame is adjusted with respect to the first frame.
