It's been a while since I last posted and I've created a new account. I currently own a 3720 (300CX, forks, rear remotes, mids) w/ 60 hours and I'm struggling with whether to go larger with the 4520. I have about 120 acres with about 20a in CRP and waterways to mow, 30 acres of timber to deal with, about 2-3a of food plots to plant/manage, and about 1/4 mile gravel drive to maintain. When I bought the 3720 I thought it would be plenty of tractor and I had some clearance issues with overhead openings in buildings that would've required I fold the ROPS on the larger tractor, so I went with the 3720. Originally I started out with an 855 and the attachments that I bought for it (5' BB, 6' rake, 5' cutter, 5' tiller) were probably too big for the 855 and are now probably on the small side for the 3720. I still have the 855. The issue is whether to move up to the 4520 with the larger/heavier frame and get a larger cutter and maybe a bigger BB to work the driveway. The dealer is offering a trade of the 3720 plus 10k for the 4520 (w/equal setup). Moving some large sections of cut timber recently with the forks made me wish I had the larger platform and I suppose I could handle the low door openings by folding the ROPS on the 4520. If I were to be really honest about things I like the looks of the 4520 better and maybe that's what is driving me to think about doing this. Could somebody help me sort through this because I'm starting to go crazy trying to figure this out! Sorry about the length of this post.
