Checking the rpm
The swivel gear's rpm can be checked in 2 ways:
The swivel gear is factory-fitted with a sign that gives the tractor's PTO
shaft rpm.
• If the sign shows 1000 rpm, the machine must run at a rotational
speed of 1000 rpm.
• If the sign shows 540 rpm, the machine must run at a rotational
speed of 540 rpm.
Maintain the rotational speed on the tractor PTO outlet
It is dangerous to connect a tractor with PTO = 1000 rpm to a
machine intended for PTO running at 540 rpm. The machine is not
designed for this speed. It can result in damage to the machine
and be dangerous to any persons in the vicinity.
The swivel gear can be switched to 2 modes, so that both
rotational speeds, 540 rpm or 1000 rpm, can be used. The
machine is factory set to be adapted to tractors with a PTO outlet
running at 1000 rpm.
Whenever possible, one should always aim to run the PTO outlet
at 1000 rpm. It is especially recommended that tractors with power
above 70 kW (90 hp) on the PTO outlet run at a rotational speed
of 1000 rpm, as high rpm exerts less load on the PTO shaft.
