Unimog/chipper questions

[Le Sanglier]

Hi there,

Bloke over here got a unimog a while ago which is handy as he's a mortgage consultant (yeah I know!) anyhow he has brought a pto chipper for it, here it is with him, as he knows next to nothing about them he asked me to come over and cast an eye over it.

Its olds as you can see but seemed sound enough,blades not bad, anvil reasonable, rollers not worn at all really, we start it up and it's really disappointing, chute blocking balking on the sort of stuff that my TW eats.

So in an effort to get it working properly (cos it should be awesome) some questions.

1 what revs should it run on?

2 presumably it goes on the fast setting on the PTO

3 it has 5 belts between the shaft and the wheel how tight?

Other observations on this old girl would be welcome.

Here's another pic, if this is the wrong way round I give up!

I used to run my to 200 in the 1000 speed for pto at about 2000 rpm the belts want to be tight!are they slipping?

[nick channer]

You might have the mog in 540 pto speed and not 1000..

This caught me out when I went from a rear mount green mech which was 540 pto to a front mount schliesing which unknown to me at time had 1000 pto..

That kept blocking.

check your pto speeds, also check its not for a front mount as the pto rotates the opposite way

[Le Sanglier]

The 540 1000 thing caught me out at first but then we realised, interesting point about the rotation of the wheel I will go over today and check it.

I am pretty sure that's not a front mount. Its a Ganadini chipper badged as a Turner which now trades as Greenmech, Pete B will be able to give you chapter and verse on it.

 

Its a good chipper, the one I owned was bomb proof.

Yes, thinking about it the wheel was turning the right way.

It wasn't blowing the chip out properly it was just rolling it around like a cement mixer, and some very ordinary pieces were slowing it down. The blades seemed reasonable, but I guess the first thing is to get those done and try again.

What gap do you have between the blades and anvil?

It needs to run at 1000 rpm or it wont work at all

 

The blade anvil gap needs to be a couple of MM, as with all angle feed machines.

 

If the gap is too big it will take thin branches and "sliver" them before chucking it into the outspout to block it.

Ok, cheers.
