ROTOR SPEED
The
WMU 210 - 230 - 265
are designed to be used with tractors with a PTO speed of 540 rpm.
On
WMU 305
, the correct rotor rotating speed can be obtained at 540 or 1000 PTO rpm.
When the tractor has a PTO speed of 1000 rpm, it is advised to use it in order to obtain the maximum power
generation.
Using the machine at 540 or 1000 rpm is determined according to the position of the pulleys.
Stop the tractor motor. Take out the ignition key. Wait until all moving parts have come to
a complete stop.
Position of pulleys
(P.T.O. 540 rpm)
Position of pulleys after having
switched round (P.T.O. 1000 rpm)
Locking bolt torque on pulley :
2.5 daNm / 20 ft.lbs
.
After reassembling the pulleys, check the parallelism between the rotor axis and the transmission axis
(see chapter tensioning the belts page 23).
Never work in stony or rocky grounds.
