Stormin 9,981 #2 Posted April 13, 2019 Looks good. Pity about the frame. Re-welding and plating should sort it I hope? Share this post Link to post Share on other sites

The front axle should be welded solid to the frame. The rear trans axle, fenders, & seat should pivot side to side on this tractor. It is a strange feeling at first, but this is how it should work. Is this what is going on?? Edited April 14, 2019 by Achto 1 Share this post Link to post Share on other sites

I had one of those once too and the first time I drove it around it started to twist under my legs and just about scared the crap out of me. Thought I had broken the frame pulling it out of the brush and onto the trailer with the winch Share this post Link to post Share on other sites
WHNJ701 4,165 #7 Posted April 14, 2019 have to watch with the old simplicity tractors even if they look nice they could have expensive issues with the bevel gear box, transaxle and frame issues. I had a nice 700 wonderboy once. I looked at a few 725s but passed would like to find another one someday. 1 Share this post Link to post Share on other sites

Have to wonder sometimes what people did to break things like that. I could be wrong but that doesn't appear to be a thin piece of metal to me Share this post Link to post Share on other sites
Sarge 3,463 #11 Posted April 15, 2019 That design is known to fracture over time from metal fatigue. I always wondered how many tons of force it took to stamp out that heavy frame section. They way they designed the thing there just isn't enough support for that type of joint. From what I understand, any type of rough terrain will eventually crack that area of the frame pivot.

Stormin 9,981 #12 Posted April 15, 2019 The welding doesn't look great either. Looks like it wasn't prep'd. I'd reweld it and add some reinforcing plates. Share this post Link to post Share on other sites

Is this what is going on?? yes it is the part that is welded broke it was welded together once before from a break and now has broken again, well the new weld did not take the 2 supports do not line up on is about 2 inches higher then the other the tractor now drives like a car with a bent frame, so i went to ebay and found a frame really close in looks but we when i transferred all the parts to the new frame the front was different no cut out and its a longer frame as well its going to take a while to fix it right, just wish i really had the time to put into it i have 500 into this now lol i dont wanna loose that much so ill make the time some how Share this post Link to post Share on other sites
