    I think I'd take it to a shop and have it done professionally.

    how did that get broken? severe abuse, or an accident?

    I don't abuse my equipment, it just broke. It's strange because I had it sitting outside. The broken part of the frame was rusted. I was thinking on welding it myself using a piece of angle to fix the problem.

    i'd weld it myself, and fishplate both sides. i'd be more concerened why it broke in the first place. tubing doesnt usually just break like that. if you're not a welder, dont mess with it. let someone else do it. im guessing maybe 2 hours?

    I'm starting to think vandalism. I live in a bad hood. Still not sure why it would break. metal fatigue?

    That will have to be plated on both sides of the break to be welded. not too big a deal as long as there's enough roon to get the welder in there.

    First thing I would do is grind all the paint off then butt it back up and use a 6011 3/32" rod with the welder set around 60 and weld it back up. Then unbolt the frame from the power unit and grind the weld smooth on the inside and outside then cut a couple pieces of 1/8" flat bar (as mentioned above) the same width about 4" long and weld them on the top and bottom edges with the same size rod, There is more strength welding on the corners of the tubing than in the flat surfaces with angle and it will give you a small groove area to fill in for a little larger deeper bead.

    Did the weld itself break or did the metal beside the weld break? If the weld was good then the metal will break before the weld. If the weld was weak then it will break first. I am seeing more and more "cold" weld on mowers now days. People not knowing really how to weld and not having the heat up enough or something and the weld just laying on top on the base metal and not really how much if anything. Any way before you do any welding you need to disconnect the battery and voltage regulator or the charging system may be damaged. And on a engine that have a computer (ECU) it too must be unplugged or it will be damaged. I can not tell from the photos but that looks like a week spot to me any way. It should have been reinforced. I think is some one wanted to mess up your machine they would go about it a little differently. I think it just got tired of holding, nothing more, nothing less.

    That was another thing I have thought about. A week spot. If you see the first photo, there's a weld with verticle steel for the bracket. It broke in front of that.

    I mentioned it to my dad the other day, he seen it. He told me this: Use the 110 lincoln welder, set it on 105 if needed, 115 or 120. Use 6013 welding rod and smoth all areas before welding. Weld the angle on the backside smooth the weld and place a piece of flat bar on the outer side.

    scrub all areas well before re-welding because if something called slag. Then paint with primer to avoid rust.
