Currently using a 48 Bobcat, looking at buying a used 98 48" Giantmow. Looks a little newer than what I'm using. Wondering about the cut quality, it's got the Kohler 15. I like the idea of having more than one speed, just not sure if it's going to cut better than what I have now. I'm mowing about 3/4 acre, lots of turns and obstacles. Any feedback appreciated.
