Found a old tiller today for free

[Pete Judd]

Found it while hogging a friends back 40, It has set for over 20+ years, but all the bearings turn, took pic's but don't know how to post. Already drug it out of the woods, and starting to modify to fit my tractor.

I would spend time/money getting it operational before worrying about it fitting your tractor. It appears to missing some components? Where’s the PTO shaft? That’ll be a nice find if you can get it going.

It was belt drive to whatever tractor it was made for, I am looking for a right angle gearbox like those used on a brush hog to mount. I is a little over 4 ft wide, and had a 3 speed gearbox chain drive to the tines. I am also moving the top link mount aft on the tiller to make room for the gearbox.

I guess you have calculated rotational speed with the proposed new gear box to achieve the proper tine speed? For instance, the Maschio tiller has a tine speed of 208rpm at 540 pto speed. Not saying this is critical but changing from belt drive to shaft drive might make a big speed difference. I actually run my old Yanmar tiller in 2nd pto range on 2nd passes sometimes just to fluff the soil a little more. Looks like an economical project to me. :thumbsup:

The simplest and most available gear boxes I know are rear differentials out of cars. A small rear wheel drive Toyota or Nissan from the early 80's may just fit that frame w/o much work. All this assuming the rotation is correct that would need to be determined first obviously.

Post hole diggers used to be made from old diffs all the time in the old days.

The one side axle hub can be the mount on that side using one of the wheels cut down and welded to the tiller frame and a gear could be attached on the other hub and a double width chain could be used to attach the gear thats there now to the axle hub.

Just an idea and since you have a Yanmar you probably have a multi speed pto so making the tiller spin at the right speed shouldn't be a problem.

Now here is a guy that KNOWS how to tinker!!:thumbsup: That tiller look pretty heavy duty, probably worth the effort.

Thanks for the nice words sir I always give it my best!

Some see an iron pile as junk I see it as a gold mine of opportunity.

Similar: Before the era of OSHA - something I used to see locally was hay bale tossers made from differentials. The operator sat up on a seat like a backhoe. A laborer on the ground would set hooks on a bale, the operator would stomp on a brake remaining on one end of the differential, and a cable wound around the other end would toss the bale up on the haywagon for a laborer there to stack neatly. Fun to watch, and obviously the operator needed great skill to use this efficiently and safely.

Does anyone have a photo of one of these?

They have a few, i have the catalog right in front of me and see a few that may work. :thumbsup: Sweet find, your tiller is in much better shape than mine was.:ashamed::laughing::thumbsup:

I have been looking at the Argi Supply brush hog gear box, rated 40 hp, for $119 plus shipping, 1:1.47 ratio, which would put the output speed at 790 rpm. I have not yet counted the teeth on the tiller to get the speed of the tines to around 200 rpm. But also got a line on an ex importer in the area that may have yanmar tiller parts.
