I live in rural SD. I mow about 1-2 acres weekly. I have a fair amount of slopes, uneven terrain, and trees to mow around. I am wondering if the hustler fastrack 48, or the hustler super duty 42 would be better for my yard. Mostly wondering about the slopes, I test drove a minifastrack 36 yesterday from a friend. It handled the slope pretty good, but I'm wondering if the wider/heavier 48, or the heavier/bigger tired super duty 42 would handle better for the money. They are both around $4999 here locally. I am leaning towards the superduty, I think the bigger tires would benefit me and the width isn't real critical. I currently mow with a snapper 21" push! Which takes forever. Thanks for any input.
