Modifications to a Jinma chipper

[weldingisfun]

Here are a couple of modifications that I made to my Jinma chipper:

First is a storage cart. It is a dumpster diving special. I could not have asked for a more perfect fit. I would consider this type of cart an absolute "must have" for anyone that owns this chipper. The chipper itself weighs about 800 lbs and is impossible to safely move when not on the 3 point hitch. When the chipper is on this storage cart it is effortless to move it in the garage on the concrete floor, and a simple matter to hook it up to the 3 point hitch lift arms. Highly recommended!

I completely agree wth Beau. You must have a dolly if you own one of these monsters. Since I was not as lucky as Beau to find one, in a dumpster, that looks like it was built for the job, I had to build one. Just finished it tonight and want you guys to take a look at it for some constructive criticism.

The T-bar is to prevent the chipper from tipping over. The feed chute tends to make it little unstable.

There is one more mod to be made to hold the PTO shaft. I marked it on picture 04. It will be a piece of 2x2 angle welded on, as shown, to form a cradle for the PTO shaft.

My wife moved this around inside the shop with little effort.

Picture 02: The dolly by itself showing the T-bar.
Picture 03: Chipper mounted.
Picture 04: Future mod to hold PTO shaft.

That is a nice addition having everything you need in one location. Saves the trip back for extra items. Why does it feed slowely with pine needles ? I have alot of them to chip and this is the first I have heard of this problem. The closest dealer is about 65 miles away and he is going to call when he gets a chipper in. This will be a good test if it can handle pine branches. Do you run out of power or will it simply plug up ? This is very interesting, thanks for the info.

We keep the woodchippers in stock along with all the replacement parts,and ship these chippers all accross the USA.Make sure you dealer has some of the common parts in stock in case you need anything,

Rather than start a new thread, I'll just add my list of Jinma chipper mods here. Please let me know if anybody wants further explaination or detail.

1. Milk crate for holding stuff. Just sits right there and is secured with bolts and fender washers (bottom and back)
2. Custom top link adapter for quick-hitch hookup. This works surprisingly well and I don't ding up the sheet metal when hitching up. It's removable so I can remove the pulley sheild if needed.
3. Chainsaw scabbord. It's quite possible this will only work Stihl saws. I use a bungee to hold it in place (not shown)
4. A place to hold long handled tools (like a pole pruner). The key there is the tool handle fastener available at Bailey's.
5. Skids. 4x6 PT boards, about 42", each bolted with 2, 3" peices of 2x2 angle iron.

Other mods still on the 'to-do' list:

1. Foot actuated feeder control.
2. Grind the teeth on the feeder
3. Welding on a 'lip' where the chute meets the chipper. This one's harder to explain, but it will make sense when I do it and post pictures. However, it won't be until I need to service the blades.

I think I know what you mean by a lip. I put a piece of 1" metal on each side of the chute where it meets the chipper. I pitched them towards the chipper. I did this to keep the honey suckle vines from wrapping around the feed roller shaft. It works well.

Hi gang, just ordered one myself, and will be doing the "servicing" to get it ready to use I hope this weekend.

The 2 X6's under the bottom are for added stability I am guessing?

Can someone explaing the "lip" mentioned above, or have a picture? I will be taking mine apart somewhat and looking it over close, and I imagine that would be the time to take care of stuff like that.

I am off to read some of the one million other threads on these machines.

Hope I am doing the right thing

An earlier mention in this post was asking about branches clogging up while feeding them. This happens a lot on most any chipper. If there is so much green stuff that has short small little stems the the feed roller or or cutting blades don't catch them and pull them in. They will build up and clog the inlet. I have a Vermeer Tow type chipper that this happens to as well. I usually keep larger branches in reserve to shove the small branches through. The feed roller can capture the "fluff" and pull it into the chipper. So it is common on 6" and smaller chippers. Just keep your cotton picking hands out of that chute!

Yes, very much so. In addition, it raises the height by 3.5" and keeps it off of the dirt. Additionally, I can use it to haul/store stuff in the back.

I used pressure treated 4x6s, but I suppose a 2x6 could be used as long as it doesn't extend too far.

The 'lip' that I was thinking about was to counter the effect where the sheet metal flexes and larger stickes with square ends get stopped by the anvil (see the side view, and the lip in red)

I like the idea that Kays Supply mentions. On each side of the roller, there are places were small brush & vines and miss the roller and get wrapped around the shaft. I've tried to draw my understanding of this in the top view.

I went through a pine plantation chipping 4-5" trees and a ton of branches to open a path. My 9" Bearcat never plugged or hesitated. The heavy 4 knife rotating assembly sure works fine. I may have to get the hydraulic feed because it sure can wear a person down dragging and feeding.

srjones You drew the lips like I did it. The " lip" to span the gap where the anvil sits is next on my list. I have hangups there too. I don't want to grind the anvil , that would waste one turn over for a fresh sharp anvil. I would be kind of unhappy if I didn't have a few things to improve on it. I have chipped pretty much every limb I can find.

The foot control on the feed roll really helps alot!!

And the plates that attached to the 3pt lift arms were made of cheese on my unit. Replaced with some real steel and no more bending. Otherwise pretty good.
