DF9.9T/TH “K8” (’08) MODEL 12-31
SHOCK ABSORBER CIRCUIT
This incorporated safety feature is for protection of the gearcase and prevention of internal PT pressure
build-up in the event of an impact.
(1) The pressure from a sudden impact will make impact relief valve J open, allowing oil from the upper
chamber D of the tilt cylinder to flow into the area between the tilt piston and the lower chamber F. The
tilt rod will then extend.
