Botex grab option

[Busy Daddy]

I am just about to order my new roofmount for feeding the chipper

My question is , are the biomass grabs worth using rather than the standard ones are they that much better ?

[woodworm]

Logs= Log grab

Brash = BRASH GRAB

Mixture=Brash grab.

Clarke brash grabs are superb- speaking from experience

[arbwork]

log grabs will dig more dirt, you will get less with brash grab but this will not be completely clean if feeding chipper brash grab will be better/ cleaner, in my experience you will always get some dirt or worse! when feeding chipper with crane, some are less rounded and hold less timber check out the capacity and compare, saw these at elmia this year, good luck

It is all chipwood no brash

I had a problem on sunday with lots of soil going through , it really takes the edge off the blades and more the quality suffers

I try to release the grab a bit , but dosent always work

These 4 finger energy grapples were good on brash and timber. If you want to just feed a chipper then probably worth the investment. If you want to use it as a forwarder crane too, best stick with the log grab.

Just out of interest what sort of through put are some of the bigger chippers getting through

I managed three and a half artics full in the day which I guess is about 80 to 90 tonnes if wet

Without the soil issue I think I could of managed the extra half load

Brush cutter those are the ones

It is 90% biomass I do

sorry for the derail, but which chipper do you run, and how many hp/kW?

 

thanks Rod

yea its a heizohack 8-400 with a valtra t 170 chipped with 176bhp at 1500 at the shaft , feeding with a jcb 803 (vintage) with the smaller botex grab fitted

thanks, I just had my pile chipped on Monday(similar outfit), 150 cu m of chip but quite a bit of that was on the brash pile so output was bound to be lower.

 

I stack my woodpile on railway sleepers to keep the dirt out but I could see some turf getting in from the brash, difficult to avoid.

 

Which part of the country do you operate?
