A gravel is not that hard to maintain if you do it right. takes some messing around. the crown on a gravel drive is a must. any holes that collect water are a non, no. so when the kids dig holes when they spin there tires, run a drag and fill them in.
The "key" to plow a gravel drive, slit a piece of schedule 40 pipe and put it "over" your cutting edge. it just bounces over the gravel. messing with skid shoes isn't going to get it.
Once you try the pipe your going to kick your self for not doing it sooner.
Float works when things are level, its not fast enough. such that when you come to a bump the front end of the tractor goes up. I can use it and react fast enough. wife not so much. if you plow does not have a center pivot and your plow has angle the corners are going to dig in.
Your better off just putting a chunk of pipe on the bucket cutting edge. did it that way before on the skid steer. it has float. actually works better.
only reason we tried the plow on the tractor loader is we didn't want to have t take the loader off to put the blower on.
We bought a blower for the tractor and are selling the plow.
also, been around construction equipment for years, got out first tractor last year. They do real well pulling stuff. pushing not so much. my opinion. use a back blade with a chunk of pipe on the cutting edge for the light snow. then leave the bucket on to push the banks back and be done with it.
I my situation had to make it idiot proof, so you drive down turn around and come back. hence the blower. As you get older keep in mind about what happens when you can't run the equipment.
