We have Tons of Heavy wet snow to plow- comparing snow pushers

What happens here

Lucas elaborates on the importance of the poly blocks in the Arctic design. He explains that older models had thinner blocks, which caused problems, but improvements have been made with thicker, more dependable blocks. He clarifies that the poly blocks are designed to be the 'failure point' to protect more expensive components. If an operator hits an obstacle too hard, the inexpensive poly block will break instead of damaging the plow's frame or the machine itself. Replacing a poly block (costing $50-60) is a quick infield fix with an impact gun, avoiding costly shop repairs.

Goal: Understand the role of poly blocks in preventing major damage to the snow pusher.

  • Impact Gun N/A — Quickly replacing poly blocks in the field
  • Poly Blocks N/A — Acting as a sacrificial failure point in the snow pusher design

What they say

pile of frozen snow the failure point is designed to be the PI block if you're talking about a block that costs fifty to sixty dollars okay and it can be change out very quick especially with these new electronic impact guns you can get from Home Depot something you got to bring back the shop okay so that's the sectional but you have ones that don't have that design right right yep so this is your top of the line this top shelf now where are we what are we looking at now this is more of a typical design yes so this is more of your typical origin design where it has a solid one-piece moldboard but where we differ is we still employ our patented and trademarked slip pitch to allow the pusher to travel independently on the pavement from the machine and this reduces drag because the weight of the machine is now resting on video the shoes okay it's resting on its tires and then the plow weight is resting on the shoes and then that allows machine to just work on pushing the weight of the plow and the snow and not itself so you can go a lot faster you have a lot better traction and better fuel savings but you can't notice on this butcher we do have a independent sectional trip edge for that steel cutting edge so you
