Now this isn't the most exciting or complex project on here, but though some people would like to see it. I don't usually think to take pictures while I am doing stuff but figured I would try it this time. Sorry if it isn't very complete.

My tractor with wide turfs doesn't cut it in the snow. I really need chains, but for now I figured I would do this since it cost me nothing but electricity and a couple welding rods. The material was all old parts and scraps from work that were getting tossed. My goal was to keep the weight out of the way of anything I might need to get at, and minimize ground clearance loss, so I decided to mount some plates under the tractor.

This is one of the plates. It weighs 202#, is made out of 2"x8" and is about 27" long. The plate welded on top is 1-1/2" thick. These were originally machine pads that were never used.

This is the view from the rear, for the brackets I used 2 1/2" x 3/8" flat stock. I used an existing threaded hole in the rear drawbar hanger.

Here is how the front attaches, it mounts to an unused hole that hangs below the loader bracket.

I used 1" schedule 80 pipe between the plates to hold them together, this is how it looks underneath. It doesn't block anything from moving, and also gives me access to the drain plug.

This is the whole thing together off the tractor, flipped upside down to finish a couple welds that I couldn't get to. Now it just needs paint!

You will have to excuse some of the welds, many were done in place as this thing got heavier I got less ambitious about handling it and welded things where they were. The pipes were probably the toughest welds since I was welding relatively thin metal to very thick metal, all while trying to go in a vertical circle. Some of the welds I was able to tack in place then drag it out to finish the welds. There was lot of raising/lowering with the floor jack and repositioning.

Like I said, probably not the most exciting thing on here but it was fun to build. I estimate with brackets and everything it weighs around 420#... not a lot and probably not enough to make a difference, but for free I guess I'll give it a try. If nothing else I probably have the worlds thickest skid plates! :laughing:

Great build! Not only did you add weight for traction, but down there you're also lowering your center of gravity. I really like it, and don't remember ever seeing ballast added this way - that is, underneath the tractor like that.

I realize it doesn't add weight behind your back axle for counter weight for loader work, but that wasn't your purpose. For traction (and side tip angle stability as a bonus), this is really neat!

Looking good to me too.
Has that ballast also a function of the sub-frame?

Thanks guys, I guess you are right though- maybe ballast isn't the right word.

I don't really understand what you are asking. Please elaborate.

While saying sub-frame I mean optional reinforcement structure fixed to the tractor's underneath for backhoe, heavy duty dozer blade, crane or any kind of heavy equipment to be attached down in the middle or at the back. I was guessing, maybe the ballast you are attaching plays also the role of tractor reinforcement along with the weight.

I've seen in YouTube a case of a tractor split up by the tractive force of another tractor/helper, while towing a loaded trailer-tank when it stuck in the mud. Thought maybe it wouldn't happen if that tractor would be equipped with a sub-frame.
OK, but that's not your case :).

Awesome build! Like was said, it puts the weight below the center of gravity.

I would have to say that it may add a slight amount of strength, but very little. While I imagine it is very stong, the brackets are not rigid enough and will probably allow enough flex that the castings of the tractor would be able to break before this actually started to do anything strength-wise. If reinforcement was my intent, I am sure I could have designed it differently to achieve this since the weights used would have had that ability. I used what was laying around to get the things hanging, and really only made it strong enough to reliably hold the weight without any thought of reinforcement.

Nice work! Don't forget to grease the zerks on the linkage tubes when you're back under there installing it for the final time!:thumbsup:
