I need a new mower to mow 15 acres, currently using a zero turn. The zero is great for speed and does most of what I want but some of the areas get a little swampy and the zero make tracks or gets stuck on occasion and gets tricky on hills. The terrain is mostly flat but does have some hills and uneven terrain and the Ventrac looks nice but is very expensive and slower and attachments are high. F2690 with 4wd looks like it would be a good fit but dealers in the area do not stock one or seems willing to get one for demo. I am not sure about getting a 60" deck or a 72" the large deck would save a lot of time but I'm worried about scalping. The zero is 9 or 10k, F2690 about 17K, Ventrac with 60" finish deck 27K. I was hoping to get some ideas and suggestions comparing the three.
