thanks.that sounds like good advice. i have never used a crane fed system yet , but hope to in the future to speed up jobs. im going about sharpening my infeed rollers as the bottom one is very blunt indeed, didnt realise how bad it was. also have learned that the hyd ram is used for crusing to grip on the down direction and up when its infeed needs to be at max. as top roller might not be able to open when presented with large logs.the rollers work spring loaded when ram is not needed.might fit one. it depends on how it gets on once the roolers are built up and sharpened.

would a jackhammer power pack do the same job. not sure what size engines they have. but they are ready to go.

its a jensen A041 chipper, with its own engine . and has around 12" x 16" opening. it has difficulty taking in brash at times. the rollers slip alot and where there is a joint in a branch.i will sharpen infeed rollers, but recon it should be capable of taking in brash alot quicker for its size. im thinking of getting a crane to feed it if thats what it takes to speed up the process.but am aware disk chippers should not be crane fed.

im hoping to fit a hyd ram to my woodchipper top infeed roller ,but not sure how to hose it.as iv never used on im not sure what to expect. (1) first of all how does this system work in the first place. is it usually spring acctuated until the rollers slips. and then you press down the ram. (2) also is a hyd ram system much better then a spring tentioned top roller in the first place? (3) is it a single or double acting ram used. (4)do i place my spool valve between the pump and the roller motor.if so do the rollers stop turning when i move the ram.

i have a az40 shredder.its 1996.i want to use it for chipping branches but it has problems at times getting a grip on the branches.if anybody is familar with this machine .any tips on using it would be appriciated.thanks.
