Chipper Chinese Chipper Review

[TonyC]

No problem, you're not butting in. We share in everything here!

DIYGuy who started this thread is using it on a 22 HP tractor. When I ordered mine they said that 20HP was the absolute minimum. Of course, the more HP the better. My tractor is 31 HP at the PTO so I can't offer a good reference. You should also consider the weight. I believe it weighs in at 800 or 900 lbs.

I can ask my supplier for more info and let you know. Stay tuned.

Good luck!

Howdy,

I am a recent purchaser of this chipper and find it meeting my expectations. I really love the mechanical feed as it minimizes the amount of required material pushing. One question that I do have for the "seasoned" owners of this fine chipper...how does one easily change the blades. I have only done this once and it required another person to help. I would like to figure out how to do this myself.
thx,
Mike

My tractor is 22 hp, and almost 3000lbs. This is the heaviest thing I can imagine attaching to my tractor.

I think a 2000 lb. tractor is really too small for the chipper.

DIYGuy,

Read the articles before I got the chipper. They where very helpful in getting the chipper assembled and PM'd for use. The problem I am having is how to reach the allen bolt and the nuts at the same time. Does one disassemble the chute to be able to reach both sides of the blade? I must be missing something simple as I can't believe that the designers of this chipper would develop something that required two people to maintain.
thx,
Mike

DIY Guy,

The last post made me start thinking about tractor size. I have a 7234 Cub, 23 HP and it is listed as 20 HP @ the PTO. It weighs around 3300 # with the loader on it. I would assume that would handle the chipper. How many HP is your Jinma at the PTO?

Thanks.

DIYGuy,

Just got done using the chipper for 8 hours or so. When I was doing the 8 hour grease and belt tightening maintenance, I noticed that the drive pulleys are not aligned. The top set of pulleys seem to be about 1/4 to 1/2 inch forward (towards the tractor) than the bottom set. How do you go about correcting the alignment as the belts are groaning as they are.

thx,
Mike

If you look at the bottom set of pulleys, the shaft is held in location by two rings with set screws. You should be able to move the lower shaft by loosening both set screws. This is the shaft that is connected to the PTO Drive and has 5 drive belts to the center shaft that drives the flywheel.

The two set rings are visible in this picture: PTO Shaft Bearings

I have not done this procedure myself, so I can't tell you if this is easy or not.

Posting a question on the CTOA may get a more experienced response from one of the many chinese dealers that inhabit that site.

As soon as it warms up here (i.e.) gets above 15F, I'll pull the blades and get some additional photos.

I believe the allen head can be accessed through the side of the unit with a socketed allen key and a universal joint, and the the nut side with a deep (17mm I think) socket. Secure the allen head and remove the nut. Be careful not to drop HW into the flywheel shroud.

A 12" bondhaus allen key should also do the trick.

Pictures to come as soon as I can.


Second Note, I don't know what the 224 is rated for at the PTO, however, given the drive line, I don't think it drops off too awful much from the engine. (Direct mechanical drive)

DIYGuy,
Finally warmed up enough to go out and play. Found the set screws (4) and even after loosening them, couldn't get the shaft to move. Tried "liquid wrench" and still no movement. Tried running the chipper with the screws loose thinking that the belts may move the shaft, but still no movement. I will post over at the other forum to see if I can get some resolution to my problem.
thx,
Mike
