    Default Snow Plow Blade Repair

    The concealed damage under the scraper blade wasn't obvious until I removed it. As you can see in the picture "Damage on Bottom Box Beam" the bottom surface of the box beam was bent over backwards and no longer supported the bottom of the scraper blade. The front surface of the box beam was also more than half gone. This meant that the bottom of the scraper blade bent backwards when it contacted the snow. If I had realized this in the beginning I would recommended replacing the blade as opposed to repairing it. The top repair also took more effort than I originally estimated. My process to repair it was the following:

    1. Clamped a 1 x 3" bar on the back of the top of the blade to straighten in out and then welded up the cracks.
    2. Removed the clamps and added the sheet metal to cover the holes, clamped it again and welded the sheet metal to the blade.
    3. Removed the clamps and added the angle iron clamped it again and welded on the angle iron.


    This process involved more fooling around then I estimated.
    I usually don't like to spend more than half of the cost of a new product to repair it. I was well into the job at the point when I discovered this, so I had to tough if out and finish it. I am hoping that it will last 3 to 4 more years. Typically light duty blades like this only last about 8 years here in Michigan, due to our heavy use of salt.

    Default snow plow repair

    don our doing a good joy on a tuff repair,during the summer re-enforced the back of your plow with maybe 3/8 x 2 inch bar. add to what you have. Shape it the same as the blade itself. take a piece about 3 inches x 3 and weld on the bottom ends of the blade,faceing out not under . That is were it takes blows, in the snow and force to felt the most.
    a little hint.you know antie splatter, or some times wd 40? before the season starts next year spray you plate and do it, ever now and then, it gives a good coating and protects the blade from salt.
    keep up the good work your doing great.

    That reminds me of a pair of plow blades I fixed up back in 07. Both were in decent shape, but had worn thin at the top of the curve at the top of the skeleton. I had lots of time to kill and got paid by the hr...I was a maintenance guy at a warehouse at the time... I ended up cleaning them up and welding the cracks up, but the blade was so thin it took 22 passes on one blade and 13 or so on the other, the longest was probably about 36" long or so.. Weld, cool, weld, cool.... After a couple coats of paint they were good to go, and I know the last time I saw the trucks, about a year ago they were still going strong. I wish I had some pics, but the facility did not allow cameras inside.

    Nice job. I know what it feels like to be into a job & realize you should of just cut it apart & started over. It happens to most of us at one point or another.

    We had another snow storm today so the snow plow got another work out.
    Attached is a picture of the plow mounted on the truck.
