My front yard is about 3/4 of an acre. I have two pine trees, an oak and cherry tree to get around. It is relatively flat at the top, but soon slopes downward at a 15 degree angle. There is no flat space at the bottom. My Toro 16HP dual cylinder tractor would spin a wheel at the bottom of the hill even on gentle turns. I added wheel weights, but still chew up the yard at the bottom if the yard is even slightly moist (which it often is). I got a 97 16HP single cylinder Walker MCGHS. It chews up the yard at the bottom of the hill, and seems to struggle trying to make it back up. (I admit I need more practice with this thing) What would you pros use for this situation? I love working in the yard so "call your local lawn service to do it!" is not a good answer. Opinions much appreciated. Thanks.
