Remote Control Snowblower

So I have wanted to build a remote control snowblower for a long time. Standing outside in the cold, getting covered in blowing snow, and tweaking my back on occasion was enough motivation for me to finally take the plunge and build the project this year!

If your really interested you can watch the complete video build log here.







Maintenance and Insights


Maintenance
  • had to adjust cutting edge 3x so far - hitting lip in concrete somewhere
  • lost spring for chute tensioner - now zip tied
  • lost drive axle keyway after a couple tanks of gas - added lock tight to set screws
  • 120rpm chute motor went bad - bad component, used 50rpm as stand in
  • now using 250 rpm chute motor - seems like perfect max speed
  • modded left stick on controller to self center - easier to use + free channel now
  • keeping chute bearing, all chains, and drive axles coated in grease and oil to prevent rusting.


Insights
  • very impressed with machine, extremely capable and working perfectly
  • compact length and width is highly maneuverable and very controllable
  • absolutely need the ability to raise and lower blower body/cutting edge
  • upped speed on left right to 100% now that I am used to controls. way more aggressive turning and more fun!
  • glad I dont have a caster in the back for stability
  • 300lbs + tracks = never stuck yet
  • longer power connector out of electrical box would be better
  • 1:1 drive ratio from motors to tracks is perfect speed and power
  • lever from actuator to body could speed up lift
  • people cant stop staring lol
  • maintence mode: ability to jack front tracks off ground with body actuator, then lift up on back and place block under frame - perfect for maintence and testing if you need tracks off of ground. The body angle also gives you decent access to sprockets and set screws. Without this replacing that keyway might have required tear down!
  • xt-60 disconnects on the drive motors was a good call for the same reason, better for testing/maintenance.
  • any thin spots in the paint will identify themselves with rust spots..
  • maybe park it on a slight ramp to allow snow on top of skid plate to drain? moisture could end up trapped between plastic skid plate and bottom of frame..should inspect in spring.
  • reason i went with this sized blower is because it felt like a good match with the track size and suspected machine weight. I was trying to keep it all in scale with emphasis on traction and not getting stuck. I also needed something that would fit in my cramped garage and that I could park next to my car without being to big.
  • maybe I should have used two linear actuators for the body, the shaft now has 1/2in of play in it. I will tear it down in spring or when it breaks which ever comes first. must be worn threads. probably steel acme thread on aluminum nut. I have been using it hard and ramming snow banks lol. Might have to develop my own linear actuators.
  • so the ability to have the cutting edge go down far enough to jack the tracks off the ground a couple inches is important for more than easy maintenance. Today I had about 3in of hard pack where the mail man drove over the plow pile by the mail box for a couple days. The tracks were just riding over it. Putting the cutting edge at max negative angle allowed the blower to dig down through it and literally break up and spit out the chunks. Had to go slow but it was amazing it did it!Tried the same technique on roof pile and it didnt try to ride up the bank and didnt have to ram it (only 17in this time though)
