Chipper WC-6 Chipper Photos

[3RRL]

Last year, exactly a year ago when we bought Loretta's Jinma along with Scott's tractor purchases, we ordered a bunch of implements. One of them was the WC-6 Chipper which is similar to the Jinma Chipper so many of you have. It was literally half price of the ones we could buy here since our freight was already paid. Anyway, we just put it together and tried it out a little.
First photo is the one on the brochure and the other 3 are what it actually looks like assembled.

Nice looking machine.

What does the flexible cable that runs out of the picture do?

Those cables are for the hand and foot operated clutch release for the feed roller. I have some photos of it coming up.

Since this is Loretta's new toy, she was responsible for helping assemble and also taking most of these photos. After reading the assembly instructions, she started to grease all the pillow block bearings. There are 2 that support the main drive and 2 smaller ones for the feed roller. It's best to grease them before bolting the base and cover on. Ken mentioned draining the gear box oil and re-filling it, but I could not find where to do that?
Can you tell me where that is?

This unit has 5 main drive belts and a swinging safety cover over the opening. I should've taken the photos while the cover was off, but you can see 4 of them clearly and one just starting to show. The last photo is of the clutch "box" and the lever which attaches to the cables. The black handle on the left of the feed chute is to lift up the feed roller if it gets clogged. The skinny yellow handle above the chute is the hand operated clutch release for the feed roller.



Below are better photos of the hand and foot clutch disengage for the feed roller. All those linkages needed to be adjusted so the clutch engaged and disengaged the feed roller properly. There was a lot of slack to take out of the cables, so it took a little tweaking on some of the brackets as well as adjusting the cable nuts. You can also see the Chinese rubber cable covers starting to crumble. I don't know what it is about Chinese rubber parts like that, but all of them go bad very quickly like on my Kama. Anyway, no big deal, it has been sitting for quite a while and I'll just replace them later.
The foot operated feed roller release is pretty handy because you can put it on either side and move it around.

Fitting the chipper to the tractor and getting drive shaft to be in almost a straight line was a trick.
I think they recommended not having more than 15 degrees angle on the PTO drive shaft while operating it. We originally intended the chipper to be on Loretta's 284. It turns out that this WC-6 Chipper sat way up too high on the 284 Jinma so we fit it to my 55hp Kama. You can see even in transport that the PTO drive shaft is not to steep an angle. It's hidden by the lower lift arms. Once it's on the ground ready to operate it was almost level. The sloping ground we were working on makes it look worse than it really is, but it's almost level. I fired up the Kama and used the 720 PTO speed. Then I throttled up to 1700rpm which will spin the PTO at around 540 recommended PTO speed.



We had a small pile of branches to try it out on. It should be able to take 4" saplings and branches but the larger branches we had were all seasoned Oak for the wood stove. We did throw a couple of 2-1/2" branches in for the photos though. Anyway we got a chance to run the chipper and crush some brush. We were happy to see it working correctly and will give it a work out next week. It was good to see it operate even on a small pile of brush.
Here are a few shots of that.

Rob, your starting to sound like me, waiting a year to put a new implement together. This is not a good thing. Hope that all is well.

Congrats on getting your Jinma, Son of a Jinma, Grandson of a Jinma chipper up and running. It looks just like mine with a few additions.

I had to replace a few zirks on mine due to non-standard size or difficulty getting the grease gun on because of another part in the way. 90º zirks can really make a difference.

The only change I would like to make to mine is a round transition on the discharge chute so I could spread the chips a little better without moving the tractor. But if you decide to do the same thing, please post the mod since you're pretty good at fabricating just this sort of thing.

Rob:

I was going to ask what your first modification to the chipper will be; but I'd say putting 90-degree zerks on those pillow blocks will be the at the top of the list.

That sucks about the rubber boots crumbling already.

Rob -- looks like a nice shop ya got -- I guess "tent city" is a thing long past... It was certainly a grand looking tent city though.

 

[3RRL]

Hahaha, you guys remember the "tent shop" then?
Yeah, that's now empty and most of that stuff is in the barn/shop now. What a difference!
The first mod I'll make is to have the chute swivel around. Maybe limit it 180 degrees right to left but not back towards the tractor? When I get to that, I'll try to make it as easy to do and post it.

We're going to chip as much as possible since we are scared to death about burning here. Even when it's burning season, there is so much timber and brush it could still get out of hand. Some of the older piles we will burn for sure, but the new stuff we will most likely chip up now.
So how are you guys liking your Jinma chippers?
It's raining today so I'll wait until next week to chip a bunch of large branches from some Oaks I took down about 3 months ago. Do you guys save the chips? What do you use them for?

The other thing is drill some large holes in the base so I can get to the grease fittings underneath and also use them for inspection holes.

What about that gear box Ken was talking about?
I don't remember seeing anything like that in my instructions? There is the clutch box assembly for the feed roller. Are there gears in there?
Is that where to drain and add new oil?

Rob,
Great photo and a great suggestion for greasing and inspection.

Could you describe more about the cables that control the feeder drive? Is that about the same size as the ones used on push lawnmowers? From the picture, it looks bigger but it might just be the perspective. As you might guess, I'm thinking about another mod.

I'll try...
You do have a lever or something that disengages the feed roller, a clutch box or worm gear drive thing? My lever have 2 cables going to it. I could reach over and pull the lever too if I wanted and that would disengage the feed roller.
All those cables on mine do is attach to that lever. One is connected to the small yellow handle located above the feed chute. When you push that handle down the cables pull the lever to disengage the feed roller. You are right, the cables are like those on a lawn mower, but really more like a clutch or throttle cable on a motorcycle. The don't need to be very heavy duty but need that adjustment where you can take up the slack. I guess a bicycle brake cable would do it?



The other cable connected to that lever goes to the foot pedal. When you step on the foot pedal it does the same thing ... disengages the feed roller. It's a secondary device in case you can't reach the lever on the clutch box or the lever on the top of the feed chute.



These are the only other photos I have of the cables.



I saw on another forum where Larry added a foot pedal to lift the feed roller when clogged. It's in addition to the lift handle on the left side. Another good suggestion I got was to add hinged covers to replace those held down with all those little nuts and bolts. That would make it a lot easier for servicing, greasing and inspection etc.

One thing I forgot to post is that the first thing we did is sharpen the feed roller teeth.
Loretta was able to get the 4" angle grinder inside and put a sharp edge on every row of teeth. No need to take the roller out on this model. It was easy to do. I rotated the flywheel using the PTO drive until each row was in the same place. We got the same angle on each row that way. Plus, the roller itself was held steady for grinding purpose.

Thanks Rob, the cable description helps. I'll refrain from any comments about getting my wife to crawl into the chute of a chipper with a grinder.

There is a guy that we have worked for in the past not that far from us that puts most of his wood chips on his dirt roads. Says that it works out good for him.

Funny you mentioned that Brian,
Today it rained so the ground got pretty muddy and soft. Loretta and I were walking over to the barn and she walked over that small pile of chips we made. She commented how that spot was pretty good ... not muddy or soft like the surrounding area.
Makes a guy think???

 

[mjncad]

How about using the wood chips for heating your house and building?

We have been using wood chips on the roads around our farms and in some parking areas. I will caution you that if they are not driven on regularly, they will start to rot, and the ground will get very punky and soft. But the roads we drive on all the time seem to stay fair.
