I have 40 acres of woods with old trails that need maintenance. 1/2 acre garden. 100 fruit tree orchard. 1000 ft. gravel drive. 6 stall horse barn with 5 horses. 2 acres lawn. I'm shopping for "new" tractor and have been shown things around 30 hp by the big 3. Kubota B3300SU and L3200 for example. There is a used Kubota 5040 with 400 hrs going for around the same price, maybe 2-3 K extra. What are the drawbacks to going with the much larger tractor?
