P7
flows over 70 litres/minute. Note, the higher the bypass oil flow, the higher the pressure in the Fertiliser
Spreader’s hydraulic system.
COUPLING THE HYDRAULICS
The live hose (red) must be coupled to a high pressure outlet point on the tractors external hydraulic system.
This take off point can be fitted to an existing double acting valve already fitted for farm machinery, or a new fitting
can be installed.
The return hose (yellow) must be coupled into the same double acting bank using the quick release coupling
supplied.
HYDRAULIC OPERATION
The floor-belt has an in/out clutch (including a double acting clutch ram) that is activated automatically from the
tractor seat when the hydraulic spinners are started.
To start the hydraulic spinners and engage the clutch, pressurise the live (red) hose, this will place the clutch into
gear and subsequently start the hydraulic spinners turning.
To stop the hydraulic spinners and place the clutch out of gear, move the hydraulic lever to pressurise the return
(yellow) hose for one second then place the lever to neutral.
The hydraulic spinners and valve control must be coupled to the tractors hydraulic system to ensure safe operation.
Please contact your local dealership or Coombridge & Alexander directly if there is any doubt. Note, the adjustable
control valve on the hydraulic valve block (controlling the spinner speed) is pre-set in the factory and should not be
altered.
VALVUE CONTROL SETTINGS (PRESET)
Danfoss OMP 50 Motor - running in Series = With the valve completely closed open anti-clockwise 1 7/8 turns out
for 850 RPM (then set the lock nut)
ALWAYS ensure tractor oils are kept in excellent condition. Beware when changing a Fertiliser Spreader between
different tractors, pump oil out of the hoses unless they use the same hydraulic oil.
Please contact your local dealership directly for operational support.
