Well, I disagree. With loaded tires, this tractor and FEL is around 5000lbs, WAY more than a Kubota
B3030. The
B3030 is a 30hp tractor and with FEL comes in around 2800 - 3000lbs. You need a little extra hp, IMHO, to move the extra 2000lbs the OP is talking about. 3-8 hp makes a difference, and, having the CK30 myself, I wish I'd gone for the CK35, and I've yet to use an implement on the PTO.
By the way, the free loader program has been going on for YEARS. It wasn't running last winter for any of the models, but came back in March (that's when I bought mine). I can't guarantee anything, but it'll be back on all the CK models again in the spring if you can wait.
