My friend Ray lives in the Upper Peninsula of Michigan where they get a lot of snow. He wore out the skids on his snow blower attachment to his Kubota tractor in one season. He sent me new skids and some ¼ x 3 stock. I welded the bars on the skids to extend their life. In the first picture you can see that the heel of the skid is worn almost all the way through. You will also notice that the wear wasnt even indicating that the shoe wasnt parallel to the ground.1. Worn Skid
The process that I used was:-I cut the ¼ x 3 to about 10-1/2 long. -I scribed the corner radius on the plate and cut it out on my band saw. -I cleaned up the radius on my belt sander. -I TIG welded the wear plate to the skid in four places. I used TIG because it was all set up. -I clamped the skid in the vise and heated the wear bar in the area shown below with an oxyacetylene torch with a rosebud tip.2. Heat bending wear bar
Next, I beat on the wear bar with a hammer to fit it to the skid. I decided to use the heat and beat method instead of my arbor press, because I was concerned with the bend exactly matching the existing skid. Then I MIG welded the wear bar to the skid as shown below.3. Wear Bar Welded

On my own 1983 Simplicity tractor I am still using the skid that came with it. I just weld additional wear bars on the bottom. After about four wear bars I cut them off and start over.Below is a picture of my wear bar on my tractor.7. Simplicity skid

Reply:Really good application for some hardfacing on the bottom of the skids. Mild steel wears unbelievably fast on asphalt or concrete.

Reply:Stoody 35 is a good all around rod for this. They do make wire for hardfacing as well.
Reply:Yeah, Stoody rod lays down a nice even bead with good thickness. Just be sure to change polarity. Oh, and get out your wallet, if you know someone who works on a quarry or rock processing plant a half rack of whatever they drink will probably get you a few sticks and they will go a long way for what you're doing.

Reply:Want something for severe abrasion but any general purpose hardfacing will work. Should be able to find in a small 1lb. pack for $25-$30. Lots of specialty rod suppliers have it in the small packages and sometimes the big box stores. It will last 4 times or more longer than mild steel. Some is run reverse polarity but hardfacing you aren't looking for maximum penetration. For those skids run beads parallel to the skids about 3/8-1/2 inch apart and you can put 2 layers for even more wear resistance. Clean the first pass with a wire brush and don't worry too much if you get a little porosity. As long as you get fusion it will work. 1/8" or 5/32" rods would be fine.Last edited by Welder Dave; 09-25-2020 at 04:29 PM.
Reply:Nice Job Don...I did the same for my Dads snowblower a few years ago.... personally, I wouldnt hard face it... 1/4" mild steel worked fine.... actually made him 2 sets... so he can swap out if necessary..... easy enough to make...Miller 211Hypertherm PM 451961 Lincoln Idealarc 250HTP 221 True Wisdom only comes from Pain.

Reply:Not to be critical but in that application the beads should be ran the other direction.
Reply:I don't know the first thing about snow blowers, so here comes a stupid question...Since the skids seem to wear out in short order, isn't there some way to accomplish whatever it is they do with wheels?Tim
Reply:The wheels would be outside of the sides of the blower. They would be running on top of the snow on at least one side.
Reply:If you can get some good AR 400 plate that would work too, in any case it looks good, that hardface will make it last a long time

Reply:Don, if you get AR and cut it with your torch don't start thinking there's something with the torch 'cause AR is prone to blowback when torch cutting. Use an old #2 or #3 you don't care about and turn the oxy pressure up a little.Ol' Stonebreaker "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw

Reply:So far the skid is working well. the larger area doesn't dig into the dirt portion of driveway and the hardface doesn't gouge the asphalt part of the driveway.10. Trying out skids

Reply:Ray took off the skids for inspection. Now that I know where the skids wear, I can apply a continuous pad of hardface where it will do the most good. The wear hasnt reached the base metal of the skids yet. Ray said that due to the larger size of the skids, he cant tip the skids any more to better equalize the wear.
I bought 10# of hardface rods that are 5 points harder on the Rc scale so they should wear even slower.-DonSmith Oxyacetylene TorchMiller Dynasty 200DXLincoln SP-250 MIG WelderClausing/Coldchester 15" Lathe16" DuAll Saw15" Drill Press7" x 9" Swivel Head Horizontal Band Saw20 Ton Arbor Press BridgeportLincoln LE 31 MP & Lincoln 210 MPThe last hard surfacing rods I bought were branded from Shark, they seem to work ok and were a little cheaper than the name brand ones. I've used Stoody in the past and found the 5/32 harder to work with than the 1/8, but I was welding on cultivator shovels which is thinner material than you have. I did some hard facing on the skids for the blade this year and wish I'd done more.
