Adding an engine to a pto chipper

[Matthew Storrs]

Depends how big the chipperis you could always get a tractor stripped down to the basics of engine and gearbox and mount that on the trailer with the chipper, trouble is a 70hp engine and box weighs around 1500kg, add a trailer at 700kg and a PTO chipper at 700kg and you can see that's a fair bit of weight for an 8inch chipper - adjust accordingly for size of chipper.

 

I certainly wouldn't bother:lol:

Find an old trailed claas forager with its own engine! usually circa 100hp straight six ford engines complete with starter, rad, fuel tank all guages controls etc etc. By far the easiest way of doing it........engine is suited to the type of work, you dont want to be dicking around with taking old engines out of lorries etc..... ballache

 

That's a big engine if he was planning on a 6 inch chipper

Easily done apart from 1 major point no ones mentioned...

PTO will normally run at 540rpm, hence you will need to gear it down using a reduction gearbox and that would be a big factor getting that sorted as much as anything.

 

Make that 2 major points

 

PTO shafts turn in the opposite direction to an engine aswell

You don't need the gearbox, most of it will be redundant anyway. Chuck it away and gear it direct from the flywheel with pulleys

Firstly, that is an awesome avatar pic. Love it.

 

 

If you have a PTO unit its not beyond the realms of possibility to build it into a chassis and add an engine.

 

If you are thinking of buying a PTO unit to convert I would think the aggro and cost would be prohibitive.

 

Second. Agreed, what's the point in all the Aggro of doing all the convention when you could easily sell the pto chipper and buy one that is already built for purpose????

 

A lot of time spent in a workshop and effort of your own time, for a machine that will most probably fail, not that I'm judging the op"s engineering skills but if you put a shaft in somewhere and it's not balanced or run a belt system and the pulleys are not perfect or up to the job the could self destruct putting you and or your workers or other people at danger.

 

Not worth the risk IMO.

Hey guys

Firstly thanks for all the replies it's made fascinating reading.I can certainly see now why it's not a commonly done practice and I don't think I'll be trying to change that. I do love a challenge but at the end of the day it's got to become a tool for work so reliability is a major factor, it's all well and good proving something can be done but for the outlay involved it would need to be more than that.

Thanks Tucky

took the words i was going to say it will be running i asume at 540rpm or 1000rpm think the first. then what power do you need to run chipper. you can then work out what size engine you will need a reduction gearbox to gt it to run to 540rpm and some way of stopping feed to chipper.

as other posts can be done a saying my old father in law use to say give me the tools and the knowhow and i will make it for you.sounds a good challenge. may be worth going on BFF workshop section and asking allways making things

JD 9630 Rich (530hp). Utube it. They do a 9630t which is the tracked version.

Bit big to run a chipper lol.

bit of buggerin round with timing you can run some diesels backwards of course

Yeah I have the die cast tracked one in the shelf.
