Chipper Stop The Burn!! (New Jimna Chipper)

miltrade · Feb 7, 2007

I just got a new Jinma 6 inch chipper from Ranch Hand Supply in Chesapeake, VA. I drove down to pick it up from Northern VA. Brought it back in my pick-up. I am running it on a John Deere 4200 tractor. I verified with JD customer support that the tractor will indeed run the chipper prior to getting it.

Ronald from Ranch Hand Supply got the machine ready so that I could immediately get it running when I got home. There are apparently a lot of things that the Chinese don't do to get it ready and they assume that you will know to grease every fitting, tighten all the bolts, and generally do things that they should have done. Ronald also created and gave me a spacer so that the blades can be kept at the proper distance from the hopper (although he had done this prior).

I had to replace the Chinese belt that runs the feeder drum, as it was fraying and wouldn't tighten. Ronald from Ranch Hand Supply sent me an American-made belt that works great.

I haven't used it too much, only a few hours, but it has operated great and has easily eaten everything I've put in there, up to 5 or 6 inches in diameter.

All in all, I'm happy after having spent $1800 versus the $3400+ for another brand of 6 inch chipper.

I am new to both this site and to tractors. I am hoping to buy both a tractor and a Jimna chipper inthe near future. I am concerned obout the weight of the chipper and would like some advice on how large of a tractor needed to safely move something this big.

I have six acres of hilly woods. So educate me so I can pick the right tractor

It is heavy, I have a 24 hp Kubota 2150 with a loader for counterbalance. With loaded tires, I am in the 3000 to 3500 lb realm. It handles it well, but is about the max weight I would ever put on that tractor and I am cautious when transporting.

Redball,since the Jinma chipper weights around 800 lbs,I would stay in the 25hp-35hp tractor range.That size tractor will pull 5'shredders,box blades,ect.
and not be too big for your 6-acres.

I have been reading, and reading, and reading the various posts about the Chinese chippers, and cannot find any reference to the problem I currently have with my chipper. It is identical to the chipper in the Chinese Chipper Review post by DIYGuy way back when....just different paint.
The problem concerns the feed roller. It is now elevated off the shute about 1 1/2 inches on the left side(looking down the feed shute)and up about 2 inches on the right side. I have greased every zirk I can find, added a bit more tension on the right side, and even used a come-a-long hooked to the arm by the roller bearing and the bottom of the frame to put some up and down 'bounce pressure'(if that makes any sense) to maybe loosen up the pivot points under the open end of the shute. To no avail.

Does anyone have a clue to what I am describing?
Does anyone have an ideas to fix this? At present, the roller will only grab limbs about 1 1/2+....and then I have to usually force feed it, and I do not like that (visions of Fargo haunt me every time my hand enters the shute....)
Thanks....I do appreciate your thoughts.

Redball, Most tractors of 20 and up HP would ballance this machine easily. 800lb is not that much on a 2000# and up tractor.

That being said, I would stick to the 30hp and up tractors in order to RUN the chipper. The chinese will say 20+ will do, but it bogs my 40 hp tractor down to chip 4.5" hardwood. It also bogs down on 6" cedar.

I do love my chipper though.

I just had mine apart because it was jamed for about a year -- my fault and I was too stupid to try to manually back the shaft to free it up. Anyway its working fine now but I did take all the yellow part off as you need to remove these to grease it. Have you looked at taking them off? There are two springs that pull down the roller. These attach to the bottom of the chipper. Under the yellow cover were the little drive shaft is for the roller, there is a place for adding oil and some other parts... see if there is a build up of chips.

Thanks for the feed back guys. Right now I think I have narrowed my choices down to a Hinmoto N249D (28hp and around #2500 plus loader) or a Yanmar FX 22D (26 hp and also #2500 plus loader) I also have another option for the chipper. My local Kubota dealer has a used Patu DC 40 for under $2K its a 4 1/2" and weights half what the Jinma does. Now If my other house would just sell so that I had some money.

My *&%#@$ contractor got my house ready to occupy six month late so I missed the super hot real estate market .

There is no problem that can't be cured with adequate applications of brute strength and ignorance

I would look at three things:
First as already mentioned by SOS check your two tension springs under the feed chute.
Second: On the right side, looking into the feed chute, there is a stop (flat bar stock) welded to the side. It stops the feed assembly arms from dropping too low. If there is a piece of wood or something on top of it it will hold the feed roller up.
Third: Something is bent.
