Stump grinder as a JCB attachment

[ReubenHayes]

At least I know, will now cost in an uprated digger/tractor!

pick the size of grinder you want and match the flow rate of that to the machine to drive it, job site access is normally the problem.

Cheers for that

You will run into the same problem running a grinder on a 360 as fitting a flail.The flow rate available from the machine is not all available for the attachment, flow to the attachment will drop like a stone when slewing. Unfortunately slewing is a big part of grinding on a 360.

Yup,,,,,

Justin Kingwell had a second engine fitted to a (I think) 20 tonner. It is an awesome tool but doing it with the machines own system was a hiding to nothing.

I have been down the powerpack route many years ago and they work but they have to hang off the machine somewhere which is never ideal. The best machine I have built for this was when I ripped out the six pot kubota engine from the 6 ton machine we had and fitted a six cylinder perkins lorry engine. The standard pump for the machine went on the back of the engine and a massive pump for the mulcher ran off the front of the crank, this was piped straight to the mulcher head . With this the engine did little more than idle which made the machine a doddle to drive but the mulcher was spinning at about 2500 rpm tirelessly all day , the nuts Downside was with the bigger hydraulic tank and all the guarding it looked like something out of a madmax movie

That's not a downside, that's a massive bonus!

I will see what I can find, it was before the days of the Ipad and dumping all the pictures onto photobucket but there must be a snap of it somewhere.

Yes I'd like to see some of that too, it's the best solution all round, and exactly what Menzi Muck do with their unrivalled 'Powerline' setup that simply has to be witnessed running a Mulcher.

Engine Packs are a great idea, but I've yet to see someone do it to a factory sort of finish?
