Didn’t know about a tensioner or greasing. Have to check that!

It’s grease point E on mine .. The 220 is pretty much the same lay out as the 235 so don’t know if your big machine will be the same or an upsized version…. Do you keep the clutch fluid changed regular mick , I was told that was the only thing to be religious on them with.

Yes, everything is greased and moving freely. Its as if the top pulley which connects to the drive shaft of the chipper flywheel has sheared a pin, if thats how it drives the flywheel?

[MattyF]

I would say clutch then… but I would definitely speak to overland tomorrow to confirm, I’ve found there mechanic spot on to speak to and talk you through repairs if you have any issues or need spares.

Don’t know the machine but is there a key way on the flywheel shaft that could of gone? If the clutch is engine end and the belts are turning I would guess the problem is at the flywheel end. Does the top pully turn with the belts?

[TGS Landscapes]

Yeah will give them a shout tomorrow.

Yes Will, the belts turn the top flywheel too.

So the clutch is on the end of the cutting fly wheel and not the engine  , it allows it to spin down when the engines turned off unlike say a Timberwolf which comes to an abrupt stop when the ignition is switched off which puts a lot of force on the bottom end. 
If the belts are turning from the engine and to the clutch the rest is doing nowt I would say clutch. 
I’ve circled it in red for you 🫣to make it a bit clearer that it’s not off the engine block itself !

So is that a big oil filled sprag clutch bearing?.

 

Would explain why it all free wheels but won't engage under power as the rachet mechanism is knackered.

Hope you get it back up and running soon, they are pretty agricultural chippers so relatively easy to fix.
