I've plowed the driver 2x already (actually never stopped) Did it once and once again.
My two stage ariens stopped working. The handle that I press to drive forward or reverse is all loose. Right before that it would engage the wheels as soon as I touched it, now it's loose, has no resistance at all.
Got it fixed up. After that I finish my neighbors driveway (that's when it broke) and did a final pass on mine.
There was a metal pin like bolt that held together this arm and a spring that would move with the hand lever, through a big rod, into this thing with a spring.
Not sure what it's called (cotter pin?) same thing as on spindles on cars got somewhow lost and the bolt / pin holding the assembly came loose. Took me a bit to figure out the right angle etc.
