Here’s my opinion.
I would get a 48-50” ZTR for what you describe. Yes a MMM is more Swiss Army knife but tractor mowing a lawn is the most cumbersome to all the ways mentioned. Especially under tree limbs.
I have two Dixie chopper ZTRs (bought used with low hours), a jd gt240 rider(came with the place), and my Kubota
l3301 with a finish mower or a Mott flail with finish blades on the back. And an old 22” self propelled push mower (that refuses to die).
We mow about 8 of the 10 acres every two weeks in season. It is overkill I know but it’s became a kinda adult family get together for which we all enjoy.
So to the point(s).
The Dixie with the 50” cut does the best job and is hands down the fastest. The Dixie with the 60” cut will scalp on uneven ground and has to be ran slightly slower to get the same quality of cut.
They both will tear up the ground during sharp turns without a little finesse used during turning.
The tractor is more relaxing and good for one handed driving and by playing with the 3 point to offset the mower behind, it gets into and under the brush borders around the place. I like it for the wide open area drive around in a rectangle thing. It isn’t allowed on the lawn area due to compacting ground ruts as I have ag tires.
The two swales I cut with the push mower on a 25-30 degree or so side slope.
The John Deere rider will do it if conditions are perfect but it is a white knuckle edge of the uphill side of the seat event. It isn’t hydrostatic so shifting, clutch, and brakes are involved on that one like the old days.
The ztrs will try to kill you on them. Either run off side hill or flip a wheelie uphill. Even with weight on the front.
The tractor will try to lift a wheel.
And somehow, I always seem to end up doing the weed eating and push mowing while everyone else is riding!
