Small chippers

the Honda one looks better

Of the belt drive types there seems to be two sizes, 250mm wide blades and 150mm. The extra width seems to double the weight of the drum assembly but not really gain much advantage, it will act just as a bigger flywheel

It looks capable on straight sticks, some trees are ok with this others you have to trim out every branch before you can feed it. My drum is 500mm wide, and I wouldn't want narrower because of the size Y I can just bend and stick in without cutting.

 

Edit - also the amount of small stuff I can bung in at once without it jamming.

$3499 sounds reasonable for a 1000cc machine if it doesn't fall apart after a month - are you going to import one?

Nope its too big for me to easily transport. I think the drum unit might be the same as some of the UK available 15hp machines, and being that its belt drive, would be easier to get one of those and swap engine.

Instuctions say it has a centrifugal clutch which most of these engines dont?

 

I'm thinking it would be a worthwhile upgrade for these belt drive machines, stop it stalling when over fed.

I'd say that with a little un-blocking practice, even newbie chipper operators quickly learn to listen to revs/hold/restrict larger diameter stems, to avoid stalling an engine...

 

Though I've never encountered a chipper with a centrifugal clutch (reliability/ replacement considered?), 

I'd much rather have the efficiency of a tight-ish belt on my chippers?

 

With 3 decades experience, I still might be wrong though! 

 

On a side note: 

Is it just me that finds direct chip filling of wheelie bins, a vastly more efficient way of working, in  awkward/back-garden scenario's ?

I ve not seen one either. 

The reason is it will only make chipper to block up

Still loving my gl&d titan chipper

The one in video could certainly use a bigger engine before adding a clutch but I think the small cost would be worth the time saving of not needing to hold branches back, but not to rely on it as much as the guy in video..

Not convinced it will block as the engine is still spinning at a good rate - not like trying to turn it over with stuff jammed in there.

The reason is the added cost.

 

I am happy to find out when I get one..

Hmmm...

So if the centrifugal clutch on a strimmer or saw gets bogged down, one simply lifts up the tool/cutter, revs the engine, and continues on with the cutting..

If this happens with a centrifugal clutch chipper, then I'd not be reaching down to de-bog it, without switching off, stripping guards off and restarting etc. 

 

I really don't think any 'extra cost' is the manufacturing issue here -or at least some of the more costly chipper options would be utilising the idea.

I just don't believe it will be advantageous to the user... and I'd definitely want to hire/demo it before buying, in the light of my recently burnt fingers!

Think you'll find a clutch on a chipper is a chocolate fireguard.

 

Belts are for driving pulleys as a petrol engine unless it's a brute has very poor torque, even diesels have their limitations.

 

Exception would be say a gearbox driven unit, but that's sacrificing speed for torque, with the stress controlling the feeding not the engine.
