M series tiller size

[JasonW]

Anyone have any experienced/recommendations on what width tiller to run on a M series?

Specifically a M6040. 56PTO HP.
I currently have a Terra Force YJR074, and have had several offers to buy it so I’m thinking to upgrade to a larger model.
The 74” measures to the outer edge on the tire tread on the 16.9x28’s.

Either the YJR080 or YJR090. My only concern is the YJR090 list the recommended 60-90HP.
So has anyone ran a 90” tiller on a tractor with around 56PTO HP?

If running in previously tilled soil, width isn't an issue UNTIL you go to turn.....THEN you find out 'someone MOVED that barn'.......
You should be fine with HP.

Before I purchased my Kubota M70401(64 pto hp) I operated my 6' King Kutter ll on a Cub Cadet 7360(29.5 pto hp) with no problems. I think 56 pto hp will handle a 7' rotary tiller just fine with tractor trans in lowest speed more especially on 2nd & after trips over the same area.
