  • X-Mark Mower Deck Repair

    My customer broke off the right hand bracket that supported the mower deck. I believe that the problem was that at some point in the past 5 years he hit something hard. Figure 3 shows a force diagram which would explain the dent that I observed in the top of the mower deck. The first step was heating up the dent and pounding it out against a large piece of steel.

    The 1/4" support bracket was broken off clean and also had a crack about halfway through. I grooved and welded up this crack first so that the bracket had a chance of sitting flat on the mower deck. Next I clamped the bracket straight and pulled in the bottom of the bracket flat on the mower deck. It looks like a lot of clamps, but I added them one by one until the bracket was exactly where I wanted it and straight. I welded up the spider cracks and then tack welded the bracket in place. Next I welded up the groove in the 1/4" plate of the broken bracket to the piece still attached to the mower deck.

      I added an additional bottom plate for additional support and hopefully to help stop denting of the top of the mower deck. I added an additional weld to attach the bottom plate of the broken bracket to the sides of the mower deck for good measure. I decided to beef up the 1/4' plate that broke with a fish plate, which I set back from the edge of the original 1/4" plate by about 1/5". The last step was priming and painting it. My shop was 50 degrees F so I used my 1000 watt shop lights and my 800 degree heat gun to help the paint to set up before we reinstalled the deck on the tractor.
