Cat 0 tiller conversion to Cat 1 ....???

Hi all. I have a JD4300. I bought an older MF4850 tiller from a neighbor for basically scrap weight. I was wondering if I can convert the tiller to fit my tractor? I know I can do the pins and such, but is there anything I would need to do to the gear box or yoke? I would love to be able to use this rather than fork out $1000 for something I am just going to use for small food plots and around the yard. Thanks for the help.

Anything can be made to work with a torch and a welder. As long as you do not over load it the gear box and PTO should stand up to the use, in other words stay out of hard packed ground. Since you got for scrap, use until you turn it into scrap, may happen sooner than later but with luck you will have gotten some use out of it.

Of course you could replace the gear box or PTO if either one were to give it up.




Social media is a cesspool of questionable human behavior.

Even duct tape can't fix stupid, but it can muffle the sound!

The biggest lie I tell myself is "I don't need to write that down, I'll remember it."

Logic is most useful. If only more humans would learn it and embrace it.

Yes, fabbing it isn't the hard part. I didn't know if there was something I had to do with gear ratio or anything. Wasn't sure if my PTO would over power it?

Nah, it will be a 540 PTO speed gear box. You could break the gear box if you push it to hard into hard pan but it should stand up OK.

Tillers have slip or shear bolt protection just make sure that's in. Real cat 0 you'll need pin bushings but so long as your stabilizers can be loosened enough you should need to fab.

JD 4300 has less pto HP than some subs out there now.

Sorry if I'm chiming in late, but that that MF4850 has a PTO speed of 2000rpm. It was built for the garden tractors of that time period.
