internet tells me 3005 is 27.5 hp, 3250 is 37, i wonder if the extra horse power would cover the extra width.
how do you like the KK in general? I looked at the JD, but it was almost twice as much, with the LS/KK dealer near his cost and the JD dealer holding his summer price.
I'm showing you have 6 more PTO hp and I am not powering a hydro transmission, probably a wash. With that said, I don't really have lack of power with the 5' wide though. It will till max depth the first time thru. I liked the width match to the tractor, not sure what obstacles you are going to till around. $.02
King Kutter is built like a brick, pretty sure this is the last tiller I'll ever have to buy, more than likely my kids too.
Depends on your ground. I ran a 71" on my 3520. Most of my soil is black loam so it really doesn't work like it would in clay. I moved up to the JD 681 81" tiller when I got the 3720. The 3720 struggled with it. The 4720 has no issues with it.
Your soil type and conditions will play a big part in how big a tiller you should/could usually run. I used a JD 660 (60 inch) tiller behind both my JD 970 (30Hp @ pto) and my JD 110 TLB (33Hp @ pto). Very good results and neither tractor had any difficulty to the extent that I was concerned that the pto clutch pack would prematurely wear out.
However, I upgraded to a Frontier 1270RT (73 inch) gear-drive tiller and tried it with my JD 110. Too much tiller... Not enough tractor!
Long story-short; it's better to have a "margin of power" that favors the tractor. No long term benefit to push your tractor to the max every time you hook the tiller up!
For me....tilling is a great pleasure. I have a 2520 with a 60" KK and it does great. It does too good though as it gets the job done too soon. I wish I had a smaller tiller so the job would last longer :laugh: Just get one that will cover your tracks and you'll be more than pleased and will have more seat time!
