I need a small tractor for mowing Bahia turf and was considering a Kubota B series either the 7510 or the 7610 HSD's. Looking for any input on similar size units used for mowing with the Belly mower. Also looking for a self-powered unit to pull behind like the Swisher 60". Is the "B" series up to the task? These models are 21 and 24 hp with 4 wheel drive. Will I have enough power?
