I feel like you are all over estimating my needs, and I probably did a bad job describing it.
The house will have a bit of a yard around it, maybe and acre. Then the sides of the driveway will be nice and groomed. Say 600 feet long. That covers my "mowing" needs.
I'll need to drag the driveway every so often to keep it in good shape.
I'll need to bush hog most of the rest of it a few times a year.
I'll probably have some garden work, like moving some soil, mulch and that kind of small scale stuff.
I'll probably have some drainage issues that need ironed out as time goes by.
I don't foresee needing to lift a ton of weight, although as we build, I can see uses for standing up walls and suck for a loader but still nothing extremely heavy.
I think the early on work of getting the land ready to build on is best left to either a pro or at least more capable equipment. I'm sure a pro with a skid steer or small dozer can make short work of what I need done.
That all leads me to thinking a 25hp tractor is enough, maybe a larger framed one as some have suggested. Like a B-series for example or B50 series.
That being said, the kid and man in me wants to go bigger. Lift huge things, knock over trees, and other fun stuff. Those types of tractors don't come with a MMM, which is what my wife wants and needs in order to do the mowing. She's not helpless and afraid of work so the comments about her not doing it and leaving it to me hold no weight, she's not like that at all.
I appreciate all the good information. Thanks
