Streaking conditions in swath Conditions too wet for mowing Allow grass to dry before mowing.
Blades unable to cut that part of

tain full rpm at tractor PTO, or
make two passes over material.

and cut at 90° to first pass. Raise
rear of mower high enough to per-
mit material to discharge, but not
so high that conditions listed
