Adjust Lift Arm Down Pressure
The down pressure spring on each cutting unit lift arm
can be adjusted to compensate for different turf condi-
tions. Increased down pressure will help keep the cut-
ting units on the ground when mowing at higher speeds
and helps maintain a uniform height-of-cut in rough con-
ditions or in areas of thatch build up.
Each down pressure spring may be adjusted to one of
four (4) settings. Each increment increases or de-
creases down pressure on cutting unit by 8 lbs (37 N).
1. Put machine on a level surface, lower the cutting
units, stop the engine, engage the parking brakes and
remove key from ignition switch.
2. Remove floor plate in front of seat and open the hood
to get access to all five (5) springs.
CAUTION
Springs are under tension. Use caution when ad-
justing.
3. Put an open end wrench on hex shaft of spring brack-
et.
NOTE: Because wrench can be moved only a limited
distance, it may be necessary to use a second wrench
to hold hex shaft while re-positioning other wrench for
further rotation of hex shaft.
4. Remove cap screw and locknut securing retaining
bracket, while rotating hex shaft to relieve spring ten-
sion.
5. Move spring bracket to desired position and install
cap screw and locknut, while rotating hex shaft to relieve
spring tension.
