Hello Rocks, It is similar but Not the same! The F lift system is basically a 3pt (mounted bit lower to ground) without the top link. I have set up several custom attachments to use just the lift arms & pins (cat 1) with the rear arm mounts so lifts at same angle and arc as the arms move, without the toplink to provide a parallelogram action. Not great, but OK for what I do.
The other bigger issue is PTO Speed.... the F is full engine RPM (about 2800) while a regular utility (or CUT) is 540. Have not paid attention to direction, which could be another problem.
The F is primarily a mower.... and what I mainly use it for.... the other bits I have fabricated give it additional versatility, but do not turn it into a regular tractor.... but you already have such for those duties. A number of companies do make flail mower heads which mount right up for these machines if you expected to have ongoing need for such. They not a mulcher, but can handle very rough stuff on regular basis. I would classify the standard Kubota RCK rotary mower decks halfway between a 'finish' mower and a 'brush hog or slasher'.
Our place was Very Overgrown when we bought it and I did consider such a head, but took my time and got it all mowed fence-to-fence with the Kubota 60" deck.... bit of time but no dramas .... and even with only single drive belt (vs the double it supposed to have)! And it was ROUGH!!
Good Luck!! Cheers, Rip
