Hooked my Deere MX10 rotary cutter to my 4707 on Thursday. Kicked the pto on at like 1300rpm, killed the tractor. Rev’d it up some more, kicked it on, tractor made a bunch of racket under the cab, threw a code, and kicked the pto off. Called the dealer, they came and got the tractor (90 miles for them) within 24hrs.
They say the mower is just too big for the tractor. Deere recommends minimum 60 pto hp for the lift type mower that I have. 40 pto hp for a pull type. I have a hard time believing that the tractor can’t even spin that mower with no load. I didn’t figure it would be ideal, but thought it would work OK for mowing approaches, and Ran it on a 3020 gasser for years with no issues.
Dealer is doing a good job of taking care of me… but this one has me scratching my head a little.
