5.4.1 Shortening the PTO length
Both machinery and tractor must be parallel to one another. 5.4.1.1
Pre-assemble the PTO shaft and check that the drive tube overlap is not less than 150mm, see Figure 5.4.1.2
5.5 and Figure 5.6 a.
Check that the minimum overlap of the shaft guards is not less than 75mm, see Figure 5.5. 5.4.1.3
If the overall PTO length is likely to reduce during operation then ensure that at its minimum there is at 5.4.1.4
least 40mm movement left between the guards, see dime
nsion ‘A’ in Figure 5.5.
If the PTO needs to be shortened, cut both tubes as both halves must be shortened equally, see 5.4.1.5
