Just found a guy with the same idea. Until we get some snow, so I can try mine, here's his gravity weapon...
I've actually got 2 designs for the bizness end of the poles. Trying just the blue rake "hoe" types to start. My rig is a lot lighter, with a smaller tractor, than that guy's set up in the vid. He was smart to put wheels on his rake. Also have started a 4' wide version of the avalanche type of snow rake... slides in under snow, and pulls a strip of slippery tarp material behind it, that the snow easily slides down. That will have 2 small wheels on it. I want to see how well the rakes do first.
First flight today. The snow on the roof was pretty frozen but was able to get some off the garage shed roof. Didn't break or bend anything... the rake's handle flexibility made that happen. If it was a cabled stiff arm all the way out, I'd have snapped cables left and right. Gonna be a steep learning curve as I deal with the tractor moving on uneven ground, while trying not to tear the blue heads off the roof rakes. The main frame worked great with support cables (instead of stiff arms)... just the right amount of down pressure from it's weight, but still lifts up when I drop the bucket too low... which I did a lot. I can see this rig will be useful with the right snow conditions. Sure beats lifting a roof rake and then pulling snow off. When we get some snow, will work on a video.
As a former 4 decade roof raker, (but no more, as I just had metal roof put on) to say, that I am turned on, at the least, is a understatement. That's roof raker porn right there.
... yeah, last year's two 18" dumps of snow really got my attention. Had to try something. Thinking the avalanche type of roof rake might work better and be easier to deal with. I'll give the blue scoops a chance tho.
Yea, but those 2x4's will probably be less forgiving on a roof. Watch for sun roof, exhaust fans, chimneys, and stink pipes. Other than that, your golden!
