Chipper Jinma chippers

[JerryK]

Dougster, still working my 8". I'm ditching the yallar device mine came with to disengage the feed roller. I'm going to put a pull cable around the mouth of the chipper, just behind the sheetmetal lip so branches probably won't get to it. I fab'd up a latch that the cable will operate to lock the roller when the cable is yanked. Pulling on the cable [or pushing] will disconnect the feed roller, and it will re-engage if you don't pull the cable far enough to lock it. Anyway, helps pass the time. Have to come up with some way to unlock the devise after a panic stop yet, and paint, etc. Got lots of time, and most of the metal I am using is just hacked up parts that came with it.

WOW

I didn't mean to set off anything I was just curious. I very much enjoy hearing the bad but also wanted to hear some good if there was any (and there seems to be ) .
I have 22 acres of pines with several large brush piles left from the last clear cut that I would like to make go away with out setting them on fire so naturally I am looking into chippers and other methods of disposal.

Please continue on with the documenting of your chipper repairs and successes.

Guys

I have followed this thread with great interest as I too am looking for a chipper.

This may not be a good question to ask but as it has been going on for quite some time and I was wondering has anyone actually chipped any brush yet

Sorry about this just had to ask .

And thanks for sharing your trials and tribulation before we all bought one.

Why yes I have... I'm glad you asked Jack. I'll go out to one of my chip piles and get a photo (or two) for you, tomorrow.

Okay Jack, here are the promised pics:

Building the brush pile with my Bull Grapple.


Brush pile partially reduced.


Size of chips when knive to anvil distance was about 1/4".


Size of chips when knive were set 0.02" (book says 0.01-0.03")


If possible, don't chip green wood (especially pine). A friend did that and had to basically take the chipper apart to clear the needles that had really gummed up his chipper. I had an old Christmas tree in that pile and the chipper sucked it up with no problem.

One other thing I've done is coated the knives, anvil and chute with "Fluid Film". That stuff works great at keeping the tree sap from sticking. Even with the Fluid Film applied, I would still recommend against chipping green wood. It just avoids a lot of gumming up the works, that's all.

When I first started building my brush pile, I was intending on burning it and wasn't careful about mixing dirt and brush. Now that I've STOPPED THE BURN, I'm having to shake out the dirt and debris as well as possible to avoid dulling the blades.

Quote From Will: As for the modification of the feed roller drive shaft "U-joint", I had to replace one end of mine w/ a 1/2 inch impact wobbly.
So far so good with about 4 hrs of use.


I did this too. I used a wobble impact socket. Works well and will probably last forever, but Im having trouble fastening itto the telescopic shaft in a lasting fashion. I have adhered it into the original socket that stripped out. It breaks loose occasionally on max sized stuff when the roller hits its upper stop. How did you fasten the two sides of the swivel?

Thanks for the pictures Mad I am very encouraged and impressed with the results.

Dougster, more pictures of my feed roller lockout for your amusement. Got some real USA equipment yellow paint on it. I put a 1/4 20 bolt on it that sticks up thru the slot in the original equipment guard to unlock it after it gets locked up. I welded on the ball bearing cable guides onto the corner of the chute, too. [with all this free time I have, send me your chipper and I will fix it up for you. I PROMISE I will send it back, someday.........]

Dougster, having fun with your weddings? I'm cleaning up the mess in the barn, and getting ready for the big 'setting of the knife gap' ceremony tomorrow. Today is 'watching of the NASCAR race & barley pop sampling day'. Here's updated pictures, don't let the big 5 1/2" feed roller scare you, it's hundreds of miles away....

Hi Jerry - Great pix! I'm saving them all for future reference. And that boom pole seems to be coming in very handy! Must be a really heavy-duty one for that load!

My family weekend activities are almost all done... Thank God... but I'm staying out of this thread anyway. Please don't be offended if I don't reply... I've just got nothing more to contribute here.

How did you fasten the two sides of the swivel?

On the drive shaft end;
I took a sacrificial 1/2 drive impact socket, cut it in half.
Welded the square drive 'half' onto the end of the drive shaft.(old swivel was removed)
Topped it off with a large washer for the spring.

With that done, the impact wobbly 'plugs' into the end of the shaft.
The other end of the wobbly fits over the original 1/2 square drive stub on the drum.

(if this don't make sense, I've got pics)

Yup, I'm done here, too. On to the 'replacing of the oil lines to the filter/cooler ZR2 project' in a couple days. Trying to get my inside stuff done while it stays cool out in the barn. Have a great summer, Jerry.

 

[mrutkaus]

Dumb question: anybody tried BURNING chips in a wood stove? Is there any advangage?

Howdy, John ran across the chipper in EBAY that had the driveshaft in it...

eBay: Wood Chipper 6"dia. WC6 Cat.1 3pt 25-45HP Rating (item 170110767493 end time Jul-09-07 09:39:00 PDT)

The company that sells it says it has parts on hand to sell, so I would contact them. There is already a link somewhere on this site to a video on U-Tube of a chipper that was modified with a stronger/longer driveshaft than what is on this unit on EBAY, something simular to what you want to do. You're right, the farther you can get away from the roller the less angle you end up on the universals. The mod that is on U-Tube has an idler pulley to keep the belt from rubbing on the old gearbox platform, but I plan on cutting the old platform off and will make my own farther out, maybe someday...............

Hello Guys,
That company (BETST) had on one on ebay "Buy now ($1349)" or "Best Offer", so I offered $1200 and they took it. Shipping to Jacksonville Fl. was $345 so all was $1545. Not bad considering everyone else wants $1500 and up for them. Also as far as I'm concerned (my oppinion) they are all the same units with minor changes.

Keith at BETST said they been getting them from china for about 15 yrs and the manufacturer has made design changes on requested from BETST. I think people are miss interrupting the they clam the they designed the whole chipper rather than just the improvements.

Anyone looking for one I suggest trying "Best Offer" on ebay with this company on ebay.... who knows maybe thay will take less?

I'll give an update when I get it.

I've got one from Bestco also, and although I was ready to deal with the driveline and blade adjustment issues I found that their version already comes with a two universal joint feeder driveline instead of the ball and socket thingie. It also has a big lever that raises and lowers the feed roller to facilitate taking bites of different sized stuff. That lever can be pressed down to increase pressure of the roller on the material whenever it is slow to draw the stuff in. I welded on an extra foot or so to make it easier for my wife to push the lever down, but that was just a personal touch and wasn't necessary to the machine operation.

I did have to adjust the blades.

I removed the footpedal and the overhead bar that disconnected the driveline, and put a handle on the operating lever for that that is easier to find and use.

YES, it chips!! It's eaten everything we've fed it including branches, blackberry vines, brush, and various other yard mess. I've had to stop for a few short periods to clear wet vinelike material from around the feedroller drum and it's been a piece of cake each time.

Overall it's just awesome.

This thread has been rather quiet for the past month. I just bought a Jinma
chipper on ebay through Globe inc. I am going to LA tomorrow to pick it up. I'll keep you posted on how things progress, and thanks in advance for the helpful inputs.

 

[chuck4389]

Well, got the chipper home in my Dakota pickup. It fit with a few inches to spare but it sure did make the truck squat down. 350 miles later at home it took all three tractors to unload it. the Kubota on one side, Yanmar on the other and the Deere grader blade resting on the 3PH of the Yanmar for ballast. We were able to lift it up just enough to clear the bed of the truck, then I drove the truck out from under it. It took the wife & I about 5 hours to assemble it, could have been less if there were any coherent assembly instructions. The assembly manual, as previously noted, contains mostly safety notices.

Now the problem. . . . the power input shaft is about 4 inches higher than the pto shaft on the tractor. Looks like the only thing to do is to torch 4 inches off the base of the chipper.

Does anybody have any other ideas?

I would save the original heavy sheet metal base pieces and build me a new one out of angle iron and treated wood [skids, couple pieces of old RR timbers or something like that]. You could make it longer than the original [extend it under the chute some]so it would keep the unit from tipping. There is no problem making it lower, as long as you keep the pully/belt assembly up off the ground. Lower would also make it a little easier feeding the bigger pieces. Good luck ! , Jerry

PS: I just used mine to chip the tops of three trees last week. It works pretty good and chunk/chunk/chunk/chunks stuff up pretty fast. But nothing like a commercial drum chipper, where you throw a big limb in and 'eeeeeeaaaaannnnt', it's gone. Fast enough for us old retired guys...

 

[JerryK]

Here is a picture of a 65' [most of mine are 80'er's] beech I pulled down with cable/chains/come-along last week. I chipped up everything smaller than about 4".

Which tractor are you trying to use it on?
