Deezl Smoke,
You've grown up around farm tractors so you know plenty about big project work.
But if you're doing projects for yourself and for some hobby money . . I'd suggest a different route . . Small project work. Think about all the developments created and are being built with 5 acre building sites. Then think how many guys arw running around with skid steers and zero turn mowers. My point is the middle ground. Just last week I watched this pretty lawn being assasinated by a landscsper's skidsteer. The job needed a subcompact tracror that could easily work on the lawn but be able to move big rocks and mulch. And neither a zero turn lawn mower or a skid steer were the good choices for it. Or clearing snow on long blacktop or concrete drivewats and sidewalks to be able to do a job moving cut down cut up log trunk pieces. Again not a good skid steer environment on lawns or blacktop driveways.
So lets talk about cockpit size.
1. Flat floor is imperative
2. Wider gap between control levers on each fender and the operator . . and more gap space with fall/winter ciats and expanding waistlines from when you wee 35 years old.
3. Leg room
4. Easy access brake pedal on the left and no treadle paddle hydro control but 2 pedals spaced for boots or feet larger than a size 9

5. Ability to have both 3pt hitch and backhoe on at same time.
6. A true Mulching deck option that has no discharge and DOES only require 55 total inches of width yet uses 6 blades.
I could list a long list of things that might include Kubota bx models . . . But the above list is for the Massey GC1700 series only.
A long list of features that allows a sub compact to act like a lawn mower in beautiful fashion yet handle the steep slopes and sidehills. Then turn around and till the ground . . Do post hole digging or haul loads of landscape block/rock/mulch/feature rock and not harm the lawn doing it.
And its easy to trailer.
Let lawn maintenance people do their thing with their zero turns and skid steers. While you can do the jobs they can't touch and still say "yes" to customers who want some standard things too.
But in the end . . You'll have a unit that does your things very well but doesn't push you into the tyoes of work that bigger tractors and skid steers have to take.
