McHale C430/C460/C470/C490 Bale Chopper

The C430 linkage machine should also be level and horizontal to the ground when in
the working position and this is normally achieved by adjusting the top link, keeping
PTO offset angles to a minimum. Ensure that all bolts, on both the upper and lower
linkage brackets (as shown), are tightened to a suitable torque value. (See ‘Tightening
torque values’)
6.6 PTO shaft adjustment & maintenance
(See ‘Adjusting the PTO shaft to the tractor’)
For the C460/C470/C490, the length of the PTO shaft is suitable for all known tractor
conditions. However the PTO shaft must be checked/altered to suit the tractor
combination it is being fitted to. First, fit the PTO shaft to the machine and then check
if the PTO can be connected to the tractor stub. If not, then the PTO shaft is too long
and must be altered. Typically the shortest distance on a trailed machine is when the
tractor is turned at the maximum angle from the machine. Operating on very hilly
ground can also reduce this further. The shortest distance on a linkage machine is
when the PTO stubs of both tractor and machine are aligned horizontally. (See
‘Adjusting the PTO shaft to the tractor’)
Tighten bolts Machine to be horizontal to the ground
CAUTION: Ensure the tractor is shut down
Ensure that the tractor engine has been shut down, the key removed
and the brakes applied before carrying out the following procedure.
WARNING: Measure distance between PTO stub shafts first
Never connect a PTO shaft on a new machine/tractor combination
without first measuring the shortest distance between PTO stub shafts,
otherwise severe damage can occur.
