I have 80 acres and a mile long gravel driveway. First tractor - Ford 1700 4WD. Upgraded in 2009 with Kubota
M6040 4WD.
For driveway maintenance I have - HD rear blade, roll over box blade( ROBB) and land plane grading scraper( LPGS).
I use the rear blade for snow removal and cleaning out the driveway ditches. For maintenance of the driveway - land plane grading scraper.
The LPGS has scarifiers which are used on any pothole, wash outs or anywhere I need to dig down to make repairs.
The ROBB sits on a pallet, out in the orchard, collecting dust.
The HD Rhino rear blade tries to be like a highway dept road grader - but it simply IS NOT. The geometry between the tractor and the blade just does not work like a real road grader.
For over 35 years I've tried to grade the driveway with a rear blade. Some times it will do fairly well. Most times it will turn something minor into something worse. That's why, five years ago I got the LPGS.
Just hook up the LPGS - drag it behind the tractor - driveway becomes as smooth as a pool table.
