Cutting Unit Setup and Adjustments
The following pages will cover basic requirements for cutting unit set-up and adjustment. Always use the
instructions in the Operator’s Manual or Service Manual when working on a specific model.
Reel mower performance depends on proper set–up, and adjustment procedures. An error of .010 inch or .25
mm in height of cut, end–to–end, or from one cutting unit to another, can be visible as miss-match. Although
there are design variations in cutting units, most require the same basic procedures. A surface plate,
accurate height of cut tools, and proper instruction, are essential for setting up a cutting unit.
To Maintain Performance
Check Daily
• Bedknife to reel adjustment
• Edge sharpness
• Height of cut
Check Periodically
• Roller condition
• Reel bearings
• Bedknife attitude
• Roller Parallelism
• General mechanical condition
Prior to mowing each day there are several items
that should be checked. There are several more
items that should be checked periodically, according
to the mowing conditions and mowing frequency.
Lubrication
Greasing should also be a part of your daily
maintenance routine. Greaseable bearings should be
greased after every use and after any washing. This
not only lubricates, but purges water, which is
responsible for the majority of bearing failures on this
type of equipment.
