The vertical position of the Grass-Pak ® switch is
critical to make sure the catcher box does not over-
fill causing the delivery chute to clog. The vertical
position can be adjusted by bending the mounting
bracket for the Grass-Pak ® switch.
1. Position the discharge chute so that it is point-
ing straight back.
a. Turn the ignition switch ON and move the
blade clutch to the ENGAGED position
(engine not running).
b. Open the catcher back door and monitor
the spout position (as it oscillates) and
move the blade clutch to the DISENGAGED
position and turn the ignition switch to the
OFF position.
