Please forgive me for posting in this forum -- I usually post in the Homeowner forum, but I'd really like the help of some people who have experience with slopes like BushHogBoy and Hoss65 (I don't think BHB patrols the Homeowner forum too much). Anyway, our front lawn is about an acre on a 15 degree slope. There is no flat ground at the bottom of the hill -- instead, there's a retaining wall. I have an Exmark Lazer HP 52". For me to mow across the hill is no problem. But I understand from this site that it's best to vary your pattern. I've ruled out mowing vertically, because it's impossible to turn back up the hill on the slope. But I've been trying to mow diagonally (one direction one week, the other direction the next week). At the bottom of the hill (where the retaining wall is), I've tried coming to a complete stop, and then making a zero-turn back up. But I get lots of slippage (and it's scary! ) I've also tried this: at the bottom of the hill (in this direction: "/"), straighten out ("-"), then back up, and then turn back up the hill ("/"). This works better, but I still tear the turf. The last thing I've tried is to choose a square of ground to come down the hill diagonally, then across, then up diagonally -- working my way to close in the square (actually a parallelagram). But in this case, when going across, I'm going over the same area over and over, which defeats the idea of relieving compaction. Any advice? Thanks in advance!
