I am definitely leaning towards a cab tractor. Also, I’m starting g to wonder if I should look at the bigger Grand L series (5060 or 6060). My reason for this is that they have more PTO hp and I do see a lot of stump grinding in my future. I have about 60 stumps right now from the ash tree blight, and probably another 50 ash trees that need to come down. I was looking at the Woodland Mills stump grinder and I think the L4060 is a couple of PTO hp shy of their minimum recommendation. The MX5400 has the PTO hp, but as I mentioned before, can’t have a cab with a backhoe.
I've owned four Kubota tractors including the two I currently have in addition to a BX25 and MX6000HST and don't miss the open station models one bit. Having owned the M6060 and MX6000 for close to 3-1/2 years and 4 years respectively, the BX25 for five years and the MX6000HST for a little over year, I'd never buy another open station tractor again, other than a project hobby tractor that would see little use.
An L6060 with cab would be a great tractor that most would never outgrow, and with a backhoe it would be a formidable choice. Of my two, the M6060 is undoubtedly the more capable tractor and the one I'd part with last, but the MX6000 is also a very good tractor that shines at so many tasks. I'm not ready for boating season to be over just yet, but I'm looking forward to being back in the MX and moving snow in a few months.
I used the "build my Kubota" tool yesterday and the MX6000HSTC sure has gone up a lot in price over the past four years.
Good luck on your choice.
