6 inch tracked chippers

[markieg31]

Well, having run timbercub 150s for a few years I would like to move on to something newer for a few reasons, my chipper engine is sweet but the under carriage is a little crusty, the ability for the machine to pull in material is less capable than say the 230 and the forst and Jensen's I have used. Furthermore the bearing arrangement on the flywheel I find very tedious to change and the bearings imo are to small form the application. 

The 150 does the job good enough but 230 or a forst will do the trick but I have seen a greenmech arbtrak for sale. I have no experience of green mechs, are they in the same league as the other machines ?

Not the dreaded mech🤣

Well my only experience of green mech was from circa 2008, I only did a couple of railway shifts, brand new green mech and we were at it with a tw190. The other team with the GM team tried to feed a Conny in, it blocked, they spent a long time trying to sort it. It was the timber it appeared to get stuck on! Subsequently wickdamula , ken Hogan, rip, had one and was happy with it. And someone else with a arborist 130 seemingly many happy years with out fault.

I had a gm220 with the 55hp engine. 
it did block up with conny but I reckon the terrible state of the anvil was responsable. 
I’d go for the TW over a Forst any day

Well after keeping a 150ftr going i am reasonably happy with timberwolf including the availability of parts.

If you need through put go up to a 8 inch machine, 

Conifer will block any chipper up if chipper is blunt and revs drop a little, slack drive belts will cause it as well. 

Demo all machines and then choose.

I run a Forst TR6, with the older 35hp diesel, and a Jensen A540 turntable with the 37.5hp diesel. Neither of these have ever blocked the chute up, even with wet conifer. I do keep on top of the blades and anvils. Sure, there have been times where something gets stuck under the top roller seat, but often this can be encouraged to drop out by feeding a max diameter log through. Failing that, spanners out time.

While I agree that eight inch capacity gives more throughput, I would miss the option on the Forst to take the hopper off, tracks in, and get through a 2ft6 gate. There have been several occasions where domestic customers have been happy to have there large tree chipped and left in the rear garden, saving us a big drag. Horses for course I guess.

That can be a real winner.

They get a cheaper price, you avoid the drag from hell.
