7.7 Floating Hitch
Proper setup is critical for the Floating Hitch or Floating Struts to function properly. Because every
tractor model
’
s hydraulics vary between brands and models a one
-
time initial set
-
up must be done
with the tractor model it will be operated with.
1.
Wire in the supplied harness and switch to in
-
cab 12V accessory power and plug into the floating
hitch valve solenoid. This switches the valve between floating mode (POWER ON) and standard
hitch mode (POWER OFF). *Floating Hitch Only*
2.
Hook up the hydraulic hoses to the tractor and set an approximate working height for the front
hitch using depth stops. Then set the hydraulic flow to a constant 12
-
18 GPM (45
-
68LPM) for the
Floating Hitch or 7.5 GPM (28.4 LPM) for the Floating Struts. This constant flow is required to
have oil available to extend to retract the cylinders when the tractor goes in and out of ruts.
3.
With the hydraulics turned on it is time to adjust the constant pressure supplied to the hitch or
strut cylinders. To adjust the pressure loosen the jam nut and with an Allen wrench adjust the
pressure setting. Clockwise raises the pressure and Counter
-
Clockwise lowers it. With the har-
ness plugged in and switched on engaging the float mode, raise the hydraulic pressure until the
cylinders fully extend, if they don
’
t already. Then lower the pressure until the cylinders retracts
back onto the cylinder stops. Turn the switch off, which will extend the cylinders and then back
on again noting the speed which with the cylinders retract. Continue to adjust the pressure in-
crementally lower checking the speed each time until you are happy with the speed the hitch
retracts and tighten the jam nut locking the setting in place.
Note:
Adjust your relieve valve pressure settings and flow to desired increments. More pressure
translates to more load carried by these front wheels. More flow translates to faster response time
when going in and out of divots. Set these settings to the least pressure and flow required to meet
your needs.
