Mowing Alamo AC-60 Flail on JD 790

[TommyJD790]

I have a lead on a used ALamo AC-60 flail mower that I plan to use on my John Deere 790.

The tractor is rated at 27 hp, probably around 25 at the PTO and the mower is 60 inches wide.

Does anyone have this set-up or something similar that could comment on whether the horsepower will be adequate and will I be able to maintain a comfortable mowing speed.

Any comments would be appreciated.

Thanks,
