This past weekend I was digging swales with my tractor mounted backhoe in a bowl shaped depression that's on a few acres of my property. To get into this area, I need to drive down a slope that is about six feet high with about a 35 feet of run (basically, a 5:1 slope). While the tractor had no issues going down, the tires spun out when I tried to go back up. Admittedly, the ground was a bit soft and eventually I was able to get out by driving up a 45 degree angle to the slope, but I would prefer not to do that again. While I was contemplating ways to winch the backhoe out of the depression I came to the profound realization that “I have a backhoe” and in a few hours could just dig a ramp with a shallower slope (I know, quite profound).
Anyways, does anyone have any tips or tricks for turning a steep slope into a shallower ramp? Currently, the slope rises about 6 feet in a 35 foot run, but I am thinking I could dig out a ramp that has the same rise spread out over 70+ feet for about a 10:1 slope. Tractor is a 40 hp 1967 Massey Ferguson with a backhoe having a 24” wide bucket and a front end loader. My current plans are to aim for an 8 foot wide 70 foot long slope with a few feet of steeper slope/sidewall on either side of the ramp. I would probably to start off using the backhoe to make a rough version of the ramp followed by the loader bucket to smooth things out.
Has anyone done something similar? Thanks for any suggestions!
