I am a firm believer in loading up on all of the extras no matter which tractor you purchase. This is the time to do it as others have said. The monthly payments [or the one payment] will rise insignificantly when compared to the benefits you will enjoy from the added features.
I prioritize as follows:
[1] hydraulic pump capacity for 'remotes'
* this is fairly consistent with h.p., but some tractors allocate varying GPM to different features. GPM will dictate what size attachments you can accomodate: grapple, auger/PHD, mowers, tiller, etc.
For example: The Kubota
B26 has a 11.2 GPM total. However, it only allocates 7.0 GPM to the FEL and BH remotes. That limits the choices with regards to a hydraulic PHD or a grapple. Don't get me wrong. I love the
B26. It is probably our next tractor.
[2] FEL lift capability
* this is the number that will determine which jobs you still have to hire out and how fast you can handle the jobs you choose to do yourself. Can you lift and carry said object or do you have to drag it on a plywood raft or something similar?
Every choice you make has benefits and trade-offs. The larger the tractor, the more it weighs. That creates issues of ruts in the lawn and/or other yard damage while working on a project. Storage is a biggie because a bigger tractor equates to bigger attachments which requires a bigger storage facility. You cannot leave this equipment outside if you want to maximize its resale value.
I think your making a great decision to factor in the consideration that you might move to a larger homestead. That's a tough variable to ponder, but it certainly impacts your planning. If that move seems likely, I would suggest planning for two Kubotas: not one.
Maybe you downsize your purchase at this time to a B-series tractor that can handle everything on your present acreage. I would think the
B7800 or the
B3030 w/ a Woods BH would be able to dig in your soil. Those are formidable tractors. Owners consistently post extremely favorable comments/accounts about their successes.
Then, if you move to a larger acreage, you can explore a Grand L at that time or a larger TLB. The
M59 is a beast. Two machines such as a B-series and [the
M59 or a Grand L] would allow you so much more flexibility in your project handling.
Just more ideas to consider ...
