Trailer into pto chipper

[tree-fancier123]

so what would be the worst thing to happen if you just welded it straight on to a bit of the above mentioned splined shaft?

was having a nose around at the company concerned (Midland) as they have a few bits in auction, but also seem to be into Bulgarian property, and saw a petition for wining up the company or something ,maybe they owed the revenue, seems some of these outfits that buy and sell at auction are nearly legit

I converted an older Ganadini to PTO when the engine dropped a valve in.

 

The job was pretty simple. The flywheel shaft was parallel (as most are). I simply removed the drive pulley and had an adaptor collar made to go over the shaft and bored out and key'd on the other end to take a PTO drive shaft. Don't go welding the input shaft. it would be an arse to get straight and would always be a weak link

 

The PTO shaft had a friction overload clutch with a built in over run so the tractor could be powered down and allow the chipper to coast to a stop.

 

I fabricated a stand to make the best balance of the PTO angle and in feed height so it all worked out neatly.

Closest reply to my thought process on doing it, not heard of an overload clutch I guess it's just some sort of friction slip plates so if you overfeed the chipper but the tractor can take it something won't go bang.

Overrun clutch definitely as takes a lot of stress of stuff as you drop the tractor revs.

You don't by chance have any picks of collar so when I go to fabricators I can show them what I'm on about?

 

Better get set on pulling it all apart and get some pictures up as we go.

The only problem with direct dive on flywheel shaft is you only got 540rpm or 1000rpm which may not be fast enough.

Depends how it was done. At best you are welding what ought to be a bit of med carbon steel to something unknown (the chipper) that is probably mild steel (low carbon)

 

The weld would have to be face to face between the flywheel shaft and the splined shaft which is inch and three eighths dia.

 

Worst case the weld fails, the shaft spins out of control flailing around on the UJ while the slide end comes off and flies through the air looking for mischief and mayhem

540 is to slow for the flywheel but, while some chippers may have an input speed of 540, they are geared (pulleyed) so the flywheel is doing 1000.

 

1000 is more than fast enough

have a look at an older square baler if possible to see the driveline, as it is a good example of overrun clutches and slip clutches.

I've had a old quickchip 222 in the back of the yard for a few years now with the intention of rebuilding it with a better engine but the more I look at it the less it seems worth the bother as engine is knackered, turntable is seized, hubs brakes and tires need replacing and draw bar is well knackered.

But the chipping chamber, hopper, spout and rollers are all fine so today started thinking of slicing it apart and building it up on a frame to become a handy pto machine to go out with the valtra, hopefully carrying it on the front to site with the botex behind then swap over to work.

 

Question is........

To attach the pto do I get a shaft welded directly onto the pully and run a overrun clutch pto shaft onto this or fabricate a bairing mount to keep some way of running the 3 drive belts it currently has to gear up the speed from the engine.

 

Any pictures of how other people's machines are set up appreciate or links to sauce any parts.

I think you'll find its gearing down, the engine will run at around 2500rpm, the flywheel will normally chip at about 1000, if you know what the flywheel speed will be you can just go directly on with the pto assuming its around 1000 rpm. The TP's run the flywheel at 1000 so they can be run direct off the PTO.

How will a home made/modified chipper conform to the new stricter E.U regs for safety?
