Jinma chipper - I had to....

[KML]

Have been wanting more chipper (power feed for sure) than my little Troy-Built for a few years now but it hasn't made it far enough up the priority list to justify the cost.

Well, was at my local Rural king and ran across their branded Jinma marked down to $899! It was "no tax Saturday" so they give you a discount equal to the sales tax, I was out the door for $895! Don't know how that math worked out but I didn't complain!

I was really holding out for a wallenstien but at this price I had no choice!

Now that I have it I know there are some things to address before using it.

Bought quality replacement belts
Tighten every bolt on it
Adjust and torque the blades
change the oil in the feeder gear box
put 6mm set screws in the feeder drive shaft

Anything I'm missing?

Grease job. The Chinese grease is too fibrous for my liking. Zerks are
1. tractor end of PTO shaft
2. chipper end of PTO shaft
3. beneath yellow main drive shroud (2)
4. gear reduction box (under feed driveshaft shroud)
5. left feed roller axle (under feed driveshaft shroud)
5. right feed roller axle
That's all I've found so far on mine.

That looks like the PTO shaft that came with my Liberty. Too short. I did an upgrade on mine by adding a slip clutch which in turn made up for the too short shaft. I don't know if it's necessary but it might save the belts or even my independent PTO clutch.

I'm guessing you didn't notice that the lower lift bars on the chipper are adjustable. The amount of fore and aft adjustment permits the chipper to be moved closer to or further from the tractor, to optimize the working PTO shaft length

The horse is already outa the barn regarding that slip clutch, because it was an unfortunate waste of money. Slip clutches were never intended for small belt-driven implements. By design, rubber belts smoke before slip clutches slip.

Yep, I have the lift bars back as far as they will go. The shaft would barely reach but as soon as I lifted the chipper the shaft pulled apart.

The clutch extended it just right and didn't cost any more than a longer shaft would have. I'll let you know if it doesn't slip. :laughing:

The L-shaped stop bracket can be reversed as well, permitting a further 2" or so of lift bar travel.

Also check that the spacing between the blades and the anvil is no more than a dimes thickness.

A Overrunning clutch works great at extending a short pto shaft.

You made a good buy. Ive used mine for 5 seasons, and love it.

I got rid of the chinese oil when it arrived.

I twisted my arms so I straightened them and added a piece of angle to stiffen them. I just took a small grinder and sharpened the teeth on the feed roller. That really helped it feed. I also found that the pulleys on the main shaft were not alighned. I had to move a pulley and put a shim on the shaft to hold it in place. I have had mine for several years and as long as I don't try an do more than it was designed for, it works great.

Thanks for all of the suggestions! I will replace all of the oil and grease and I think I like the Idea of the overrunning clutch even if the shaft isn't to short. That is a heavy flywheel to ask the PTO brake to stop often.

Hope to get it out and working this weekend, it's been sequestered in the barn to keep it out of sight. The wife was not too happy to see it come home so soon after the tractor upgrade. Something about me retiring next year and us having a 3 year old...too much money on toys, or something like that. I didn't catch it all There is an upside to having hearing aides..and taking them out
