2.3
PTO speed
The SA spreaders are fitted with a reduction gearbox (i = 2.31:1) as standard equipment. With this
gearbox the broadcast disc speed is approx. 234 rpm at a PTO speed of 540 rpm (
WB
spreader
model with a gearbox i= 1.25:1).
For the maximum spreading width a PTO speed of 540 rpm must be maintained (broadcast disc
speed = approx. 234 rpm with
SA
spreader models or 432 rpm with the WB spreader model).
The broadcast disc is fitted with vanes for rotating to the right as standard equipment.
Important
PTO speeds over 540 rpm (broadcast disc speed: approx. 234 rpm) must be
avoided, particularly when spreading gravel. This will increase the wear on the
stirrer cover and hopper floor.
2.4
Hydraulic drive (optional accessory)
The hydraulic drive (instead of PTO drive) requires a single-acting control valve and an oil return
line to the tractor.
Caution
The hydraulic system is under high pressure!
When connecting the hydraulic system make sure that the hydraulic hoses are
correctly connected. (Hydraulic hose with non-return valve = return line).
When connecting the hydraulic hoses to the tractor hydraulics, make sure that
the hydraulic systems on the tractor and on the spreader are unpressurised.
