2. Loosen the screws securing each end of the front roller

to the height-of-cut arms (Fig. 1).

3. Remove the carriage bolts, washers and locknuts

securing the height-of-cut arms to the cutting unit side

plates (Fig. 1). Remove the height-of-cut arms and

roller assembly.

Note: Retain all parts for use if groomer is ever removed.

4. Remove the height-of-cut adjusting screws from the

height-of-cut arms (Fig. 1).

are spaced closer together and are used more often than verticutters so that they are more effective in cutting runners and removing thatch. (6 mm) blade spacing, one or two groomings per week will probably be sufficient except during maximum growth periods. Because grooming injures leaf tissue to some degree it should be avoided during periods of high stress.

Height/Depth of Groomer Setting 1. Set the cutting reel to the height of cut that would normally be used without the grooming reel. Use a Wiehle roller and scraper for the front roller. The groomer blade height/depth of grooming can be set using the following procedure: 2. Set the groomer reel 1/2 the height of cut setting above the roller level. (e.g. for 1/8” (.125) height of cut setting , set the groomer at 1/16” (.063) above roller). 1.
