Read ths manual completely before operatng:  follow all safety nstructons.

Implement operating power is supplied from the tractor’s PTO. Refer to your tractor 
manual for PTO engagement and disengagement instructions. Always operate the 
implement at its required PTO speed: either 540 or 1000 rpm. Know how to stop the 
tractor and implement quickly in case of an emergency. Keep children away at all 
times.

When engaging the PTO, the engine RPM should always be low. Once engaged, raise 
the PTO speed to the implement’s required operating speed: either 540 or 1000 rpm.

Check the tractor master shield over the PTO stub shaft. Make sure it is in good con-
dition and fastened securely to the tractor. Purchase a new shield if the old shield 
is damaged or missing. A tractor salvage yard is a good source for older tractors.

Tractors without a 

live

 PTO need to be equipped with an over-running PTO clutch at-

tachment, available through most farm equipment suppliers. NOTE: the addition of 
an over-running PTO clutch attachment will change the length of the PTO driveline 
required. Pay extra attention to the instructions on PTO driveline installation.
