I sent them an e-mail & got this reply:
[FONT=&]Your tires, 11.2-28 hold a maximum of 27 gal per tire. At 27gal of Rim Guard you will be adding 289lbs of weight per tire.[/FONT]
[FONT=&]You don’t have to put that much in each tire, but we do not recommend putting any more than that. 27gal gives you a 75% fill rate.[/FONT]
[FONT=&]Each dealer sets their own pricing, but average cost per gallon is about $3. Might be closer to $2.75 in your area.[/FONT]
Sounds like a plan, maybe for next fall. Hopefully it's something where I can just go to the nearest dealer (Valpo, IN) with my pickup truck & get a bunch of barrels or something & have that stuff put in by the tire shop down the street from my house.
And I'm thinking about also going with car tires for the front instead of those skinny blade-type things. It'll make it harder to steer, but whatever. I once backed an 18 wheeler into a dock without power steering, so how hard can it be?
BTW I was able to do all the plowing today. The snow was melting just enough that the water dripping down onto the ice below turned the ice to slush, and I was able to get just barely enough grip to get some work done.
The couple times I did get stuck, I just raised the bucket as high as it would go because as the bucket goes up, it also goes aft, transferring weight to the rear, or at least removing less. I figured out quickly that tilting the bucket down to keep it level is a good idea so it doesn't dump 1000 lbs of snow on me (quit laughing, I'll ban your ass

).
I also FINALLY got around to checking the generator voltage after I turned it down. It used to fry the batteries til I either discovered, or somebody told me (can't remember) that there's a screw on the back of the generator for adjusting it's output voltage.
After sitting overnight in the barn, it's battery was showing 6.32 volts and after I started it, it was showing 8.01 volts. Good enough. It's basically like a 12 volt system running at 14 volts. The fender lights were dim as hell when I put it in the barn last night though. They used to be really bright. Methinks those lights are 12 volts and somebody turned the generator all the way up to make them brighter.
