Tiller Help needed for selecting right size tiller

[dixie306]

I am planning to purchase a KK rotary tiller, but not sure which size to get. I have a Kubota L4400 which has 37.5 PTO h.p. and the manual recommends a 5' tiller with a max weight of 770 lbs.

The KK 60" is 690 lbs. and rated for 25-40 PTO HP and the 72" is 780 lbs. and rated for 35-50 PTO HP.

I use a Pat's easy change hitch which adds some length to the 3 pt. so I am concerned about the max weight, but with a 72" tire width, I really would like the 72" tiller.

Not being that experienced, what would you all recommend? Thanks.

Go with the six fter, I can't remember who said this, but he was right, the tractor co's are very conservative with the ratings, my JD is appox the HP as your tractor {yours is higher rated than mine} and it handles a six ft KK tiller just fine, I had a five fter KK and it would "push" the tractor
