PTO Shaft Safety

Maximum PTO input is specified in the Product Specifications section of this booklet. Contact your nearest dealer or 

a specialised retail outlet if the PTO must be replaced with a longer one, since this must belong to the same power 

category and possess the same characteristics. An unsuitable PTO could easily break.
 

The tractor PTO shaft length may be altered to suit the individual tractor model. When the machine is in operation, the 

PTO shaft should have a minimum 1/3 engagement as shown in the diagrams.  After the machine has been hitched to 

the tractor, it should be checked in various positions that the drive line is the correct length. If the PTO is too short and 

tends to slip out of place, it must be replaced with a longer one.

Driving Safely on Public Roads

Check the local Highway Code regulations before driving the tractor on public highways with an implement attached. 

Check the reflectors, hazard flashers and/or projecting load indicators are installed when required and efficient. These 

indicators must be installed correctly and easily seen by the drivers of other vehicles.

Bystanders must not be allowed to lean against or climb onto the machine during transport or while working. Do not 

allow bystanders to ride on the machine.

MAXIMUM TRANSPORT SPEED MUST NOT EXCEED 30 km/r (18 MPH)

TRAILED MODELS MAXIMUM SPEED IS 25 km/h

If the PTO shaft is too long, it should be shortened in the following way:

•  Set the machine at a minimum distance from the tractor, then brake the 

tractor and switch off the engine.

•  Separate the two halves of the PTO. Insert the female part into the tractor 

PTO and the male part into the machine PTO, checking that the position 

is correct by means of the fixing pins.

•  Line up the two halves of the PTO together, keeping them parallel.

•  Using a felt tip pen, match mark the place where the two halves must be 

shortened as shown. 

• 

First cut shield “1” and use part “2” as a reference to cut the splined shaft.

•  Proceed in the same way for the second half.

•  Trim and chamfer the two cut ends of the PTO and clean off all swarf  

and shavings.

• 

Grease the two profiles and join the two halves of the PTO together.

•  Mount the PTO shaft and check that its length is correct as before. 

Do not use the shaft cone 

as a step
