Good call! A "purpose built" and dedicated implement will be far more efficient and convenient than an "all-in-one" tractor can do. I use the heck out of my 60" belly mower with several acres to mow and maintain. It does a great job, but there are tradeoffs that I put up with. I would love have a zero turn to mow instead! Man... having a mower with a suspension sure would be nice! Actually, In hindsight, I may have even preferred a 3pt mounted flail type mower over the belly mower, plus be useful out in the brush as well.
Tradeoffs:
Poor ground clearance with mower deck left on and susceptible to damage when doing other work with the tractor.
PITA putting mower deck on and off. Yes is is a "drive over" but still a wrestling match rolling around in the dirt with the PTO shaft, Pins, Height and suspension mechanism.
Belt drive system is somewhat exposed and susceptible to damage from debris, sticks and branches.
Mower deck must be completely removed and suspended to service the oil in the gearbox. I sharpen the blades at the same time anyway.
Proprietary (expensive OEM) wear parts. Although I will say the deck, blades and design is very heavy duty!
The tractor cooling system is prone to over-temp due to grass fodder in the air plugging the grill mesh/ radiator screen and radiator.
I was drooling over the Bad Boy Zero turns a while back.
