Chipper Jinma chippers

[chuck4389]

Good idea! I was wondering what to do with all that angle iron that came with the thing! Now what can I do with those heavy metal plates?

Originally I was going to sell the Yanmar 18hp, but now it looks to be a good candidate for the chipper. It's at the lower end of the recommended power rating but most of the work we have to do here is Palo Verde trees and Cat Claw acacia. Probably light duty compared to some of you other guys.
Then why did we go for such a big chipper? Well, we already wore out one of those homeowner style manual feed 6 HP chippers! Bought a 10hp Troy-bilt that has done fairly well, but still barely adequate for the job.

Some of the heavier angle on the base of the shipping crate might be heavy enough for braces, but I would be using 1/4" thick 2" X 2" for the base, at least. That thing is pretty heavy, and if you ever set it down hard that little angle would have lots of more angles in it, REAL QUICK !!! I cut the weld off of mine and saved it, but more for light projects.........someday...... As for that old base, take some time someday and price a one foot square piece of 1/4" thick steel sheet someday. Afterwards, you will carefully set those pieces somewhere safe and covet them for some future project, or leave in your will for your Grandkids. Steel has really went up in price lately.

The advice is appreciated. So I went and cut 4" off the bottom of the original base anyway. Guess I was too lazy to design a whole new base. Besides, after all the work my back is killing me. So I torched it off with little oxygen to spare, and welded the leftover angle pieces back on to the bottom.
May not be pretty, but it looks like it'll work.
Don't know it it's just my tractor, but I had to get a longer top link. 25" was the maximum length of the one I used when I had the box blade on it.

Tomorrow will be the final test, will it fit?

Looks like it should work fine. I have two toplinks and I had to use the longer of the two on my chipper. That chipper you have looks a lot like the ones Betst is selling on EBAY. If so, it might have the universal joint type feed roller shaft, which is a plus. Enjoy your chipper, and wear ear plugs...

I had to get a longer toplink for mine as well, due to the fact that I have a Quick Hitch.

It looks as though Jinma has made some modifications to the chipper. The picture chuck4389 provided looks like they have gone to using cable linkage rather than the rigid rod linkage that is on mine.
Have fun with it and let us know how it works for you.

OK gang! Got it running finally. Followed most of the advice here, changed the zerks, inspected, and greased everything carefully, set the cutter blade clearance to .020". That was kinda tricky because I had to remove the shields to see what I was doing. But it was worth the extra time, it's not very easy to see from the front.
Noticed that both blades are not aligned to each other, one blade has slightly larger clearance (maybe .030' more) on the outer edge. Also, the anvil plate that was installed in it was ground wrong, the bevel was in the wrong direction, so I used the spare plate that came with it.
After a bit more bending of sheet metal, tapping to restore threads, and other miscellaneous tasks, I attached it to the tractor. The weight of this monster makes it feel like the tail is wagging the dog.
We worked for about an hour and did more in that hour than we could have done with the 10HP Troy for all afternoon. So far it's working great, the wife is ecstatic. I feel like now I could write a book of advice on this thing. It certainly would be better than the manual that came with it!
It was sold as a Jinma, but there is no data plate, no name, no model no. If anyone is interested in more pictures for comparison, I can do that.
Final word of advice, get red, it matches the blood.

From the pic,it is not a Jinma but sounds like you have it working good now
Some parts will innerchange some won't.Whenever you do need parts make sure that you tell them it is a WC-06 Chipper,the Jinma is a JM-06.

Thanks affordable. I see that you stock replacement parts.
Hope I don't need them very soon, but you are bookmarked.

I just bought a used Jinma chipper, probably a couple of years old, but the seller could not find any of the documentation, which I understand is pretty minimal anyway. (He's still looking.) I'd like to get a parts diagram/list and any specs on oil, tensions, settings, etc. Does anyone have anything that they could post, email, or fax? Thanks. I've read a lot of the posts on modifications, belts, etc., which I'm going to implement.
