1.1 INTRODUCTION
Your mower was built to the highest standards in the
industry. However, the prolonged life and maximum
efficiency of your mower depends on you following the
operating, maintenance and adjustment instructions in
this manual.
The mower is designed to bag, mulch or side discharge
the grass clippings. During the assembly process at the
factory the mower has been set up to bag the grass
clippings with grass collection baffles installed. If the
mower has been converted to either mulch or side
discharge, the grass collection baffles must be reinstalled
on the cutter deck prior to bagging the grass clippings.
See Figure 1-1 for grass collection baffle location.
GRASS COLLECTION BAFFLES
Figure 1-1. Grass Collection Bae
-IMPORTANT-
Failure to install the grass collection baffle will
result in poor bagging perfomance.
If additional information or service is needed, contact your
Scag Power Equipment Dealer.
We encourage you to contact your dealer for repairs.
All Scag dealers are informed of the latest methods to
service this equipment and provide prompt and efficient
service in the field or at their service shop. They carry a
