How It Works
Pressing the foot switch sends electrical current through
it to the hydraulic valve. The valves inside open so that
uid ows to the hydraulic cylinder causing it to lower the
tines. Releasing the switch causes uid to run in reverse
order pulling the tines from the turf and back into the
transport position.
Testing
1. Disconnect the switch from the wiring harness.
2. With the button pushed there should be continuity
between the two connectors. With the button not
pushed there should be no continuity.
Foot Switch
Purpose
The foot switch engages the hydraulic valve which
allows uid to ow to the hydraulic cylinder and lowers
the aeration tines for use. It returns the hydraulic cylinder
to the transport position when aerator tines are not
needed.
Location
The foot switch is located on the platform assembly
nearest your right foot when standing on platform (Fig.
225).
