Adjusting the Cut-Off Bar
Adjust the cut-off bar to ensure that the clippings are
cleanly discharged from the reel area, as follows:
Note:
The bar is adjustable to compensate for
changes in turf conditions. Adjust the bar closer to
the reel when the turf is extremely dry. By contrast,
adjust the bar further away from the reel when the turf
conditions are wet. The bar should be parallel to the
reel to ensure optimum performance. Adjust it after
sharpening the reel on a reel grinder.

Loosen the screws securing the top bar
