Cutting Height Adjustment - Webb WERR19 Operator's Manual And Parts List

Cutting height adjustment.

WARNING! Turn mower off before adjusting cutting height lever.
Your lawnmower's height adjustment is positioned on
the rear left side. There is a single 6-position lever
that adjusts all four wheels at the same time.
The lower the level, the shorter the cut. For very thick
or moist grass, you should select a higher setting than
usual to avoid clogging and stalling the lawnmower
under the extra cutting load.
