Boss Snowplow -Failure after failure in The Back Drag Pro

What happens here

The reviewer highlights a critical structural failure: the X-brace of the plow's lifting mechanism, made of 2-inch square tubing, tore through. This breakage occurred without hitting any major obstruction, leading to the plow sitting at an angle. He explains that the plow is designed to break Grade 2, 1/2-inch by 4.5-inch shear pins under excessive load to prevent damage to more critical components. The repeated breaking of these pins eventually led to the failure of the X-brace itself, which was not designed to withstand the stress when stronger pins are used or under prolonged strain.

Goal: Expose critical design weaknesses and their consequences

Tools and materials

  • 1/2-inch by 4.5-inch Grade 2 Bolts N/A — The specified shear pins for the plow
  • 2-inch Square Tubing N/A — The material of the X-brace that broke
  • BOSS Drag Pro Snowplow BOSS — Showing the broken X-brace and shear pin mechanism

there's times when it just feels like that plow is a million pounds it's just there's no weight in theirs but oh no it's even even sitting in the shop at home go to leave and and it wouldn't lift no the boss has another wait a minute okay so you just said sitting in the shot overnight inside eat it building in a heated bill because I've noticed ours Tim will lift slow the colder it is the first initial lift will be pretty slow if you notice that on yours now Mike owns and runs a back drag Pro which is made by boss but Tim and I know power back straight blades the one on this black truck right here is made by snow power and is designed it to be able to pull snow or push snow it has 180 degree reversible wings the second whole blade that we own is made by short iron so I want to make sure that the different blades may see in this video and let's get it going but once you get it going though the oils loosens up loosens up and boom your operational that's like literally for us it's like two or three lifts and word ahead of your snow I got to start lifting a little earlier just the weight when you're when you're pulling up you know then to the pile like you describe your notes and of course went to the dealership and at first they didn't really have any good answers because its plows so new they haven't sold very many yep there's only been four of them sold in our town - to me and to the people that I know buddies of mine talk to boss and they said well there's a little module in there it's about the size of your phone and it lays flat are you talking about inside down inside of the housing where the hydraulic unit is okay that's where all the small wires come together mm-hmm and it's gel sealed 100% waterproof right what the problem is where those small wires connect on the module but they're saying is the salt adds conductivity to the electronics and it can crossfire between there and do goofy things and how long first one did that start to happen almost immediately so boss is fixed for that module is to mount it this way instead of flat so the water and salt will run off of it so you know I've had the module issue I've had the hydraulic hose break and then the the most severe problem that I've had the actual grace yeah that's part of the lifting mechanism you can see this is made out of two square tubing so Tim will you hold this camera actually broke so you got it talking about on the frame you're actually referring to this part of the plow itself right…
