If your going to mow 40 acres, I would consider an 85-90 pto hp tractor with MFWD (40-50K) and 15' batwing mower (14K). It will still take several hours.JWB53 said:i've been looking at bobcat toolcat to mow 40 acres, but 50,000 is a lot, is there another uv that i could consider, i do like the 90 inch deck option on the toolcat but will consider pulling a deck to save $ thanks
