Conundrum on Jinma Chippers - 6" or 8"

[grsthegreat]

i have the 6" model, and have owned it and used it every summer since Jan 2006. I finally had to replace the blades, and sent the original off for re-sharpening.

Other than that, i have had NO PROBLEMS.

best money i ever spent.

I hardly ever chip above 4" cause i use the larger wood for fireplace. but occasionally i have gone up to 6".

I used to use it on a 25 HP tractor and it worked ok. it works GREAT on the 45HP version i currently own.

This is the one I have. They've gone up a couple hundred since I got mine. Haven't had any major problems with mine. Run the machine at 540rpm even if chipping small branches. The chute will get stopped up if you don't. It needs the full air flow to keep material moving.

The flywheel now has 4 smaller blades instead of 2 like mine.

That's heavier than the Jinma, and $1,000 more.

Stay away from liberty. That's where I got mine from. They are full of BS and lies. I don't want to.be so down on liberty, jinma. But I just don't want others to make the same mistake I did. Please just spend the extra money and go Wallenstein!!!

Until I have a reason, I can't knock Liberty. The purchase included free shipping and a spare blade set. They sent the wrong blade set but no problem returning for an exchange. I'm sure Wallenstein is a good chipper and I'd like to have one too. The WoodMaxx 8" is once again the same Chinese chipper for $2189.00. Actually I'd like to have a Vermeer BC1000!

I can't justify spending too much on a chipper. I prefer the old brush eliminator method (burn pile) but for the past several years we've been under a burn ban most of the time. I've got two big piles just waiting for a rainy day.

My problem also. However with a small sawmill producing "chippable" edgings in quantity I'm looking into wood gasification Build It ｫ Gasifier Experimenters Kit .

I had a Wallenstein bx42 manual feed chipper that was a royal pain in butt to feed, sold it because it had to be tended continuously and got a 6" Jinma with mechanical power feed, did a simple mod to the feed drum and drive shaft ,made the teeth courser , it pulls pretty wide spruce branches no problem , and it works like a champ behind my MX5100, lots of hours and no problems, well worth the money in my opinion.

Did you sharpen the teeth? The only feed problems I've had was with green cedar that bunches up and the roller can't grab it. I just keep a 2" limb handy to push it on through. One other thing I might suggest to others is to spray some WD-40 or chain lube onto the flywheel at the end of the season. It keeps the knife bolts from rusting up from the tree sap. I just throttle down and spray into the hopper while it's still turning.
