Weight defines what a tractor can do. HP just lets you do it a bit faster.
I'm on 5 acres & do some side work as well, mostly mowing & driveway grading, some post holes. I have a
L3200 that has served me well. Its 32hp & the same frame as the
L2501,
L3301 &
L3901. I hear the
L2501 is actually the same engine as mine, just derated to get under the 25hp emissions limit & actually punches above its weight. The 3000 series is a good comprimise between size, power & manuverability.
I am about to sell mine though. I'm upgrading to a cabbed machine. The
L3560 is double the weigth of my
L3200 & under powered. The
L4060 &
L4760 are even bigger. I'm debating between the underpowered
L3560 that is a bit smaller & the better power to weight ratio on the
L4060. They are double the price of the economy ones you are looking at & I'm replacing, but I want to not freeze my *** off or get icesicles in my beard.
Any of the economy Kubotas will do you pretty well. If you are going to be doing a lot of mowing, PTO work or roading, get a higher HP machine for the weight. My
L3200 wheezes a lot roading up hills & running my tiller, not to much mowing unless it really heavy brush or grass. If you aren't in a hury the
L2501 will do the same job, just a little slower & save you some cash & emissions gear to wory about.
