A ton of advice...as usual. A lot of good points. It's your tractor and you can work at your pace. Sometimes it will be worth hiring/renting something bigger or more featured (like a rock rake to prep for grass). 90-96" snow plow is a fair size. A box blade for counter balance is helpful. You may find a good use for a grapple. I'd keep my eye out for a decent used snow blower for larger storms if you get them. I also have 60" forks,
chipper, York Rake, and a rock rake (Harley rake). I have a post hole digger (PHD) which the
M7060 will run and use it on my excavator (I have a plate to run the SSQA tools). From what I have rear don't get overly excited about the PTO PHD as the exciting is erased when you get an auger stuck. They make units which will run on either tractor you are looking at. The tools all have their uses and picking the right one can make the job go a lot quicker.
I have a
L4240 no cab which I am trading for a
M7060 with cab (was looking at the
M6060, but its a no brainer to go up to the
M7060). I think cab a non debate topic. Next is size...I wish I had a heavier tractor for plowing. My tractor weighs about 3500 lbs. (The
M7060 is over 5000 lbs) plus loaded tires and I normally have a box blade with weights and chains (good Tyrgg chains) for plowing. Straight is good, but cornering is not so good. I run R1 tires and will run the radial R1 tires on the
M7060. I have some heavy pallets of 42" wood for my outdoor boiler...with wet wood they max out my loader. The radial R1s will be nice for this, otherwise I would run R4 tires if I stayed with a Grand (looked at the
L6060).
My Dad has a
B3000 with a cab. Nice tractor which he uses on a small area. It definitely is no where near the
L4240. The
L4240 is my 3rd tractor and I find myself maxing out the loader often enough that with the desire for a cab is also the opportunity for a stronger loader.
I would think that you would be happy with the
L4760 and find the HST very useful. It sounds like your space may find the
M6060 not as smooth to run. In the case of the L Grands I think I would run the R4 tires as the R1 tires are pretty small. I run my chains year round. With the
L4760 you get the larger loader (I have the larger loader for my era of tractor). The difference with the
M6060 is not huge, but will make a difference if you want to handle pallets or large rocks. Mine does pretty good with loading logs for the sawmill, which is my more common loader work.
I found the PTO power to be sufficient. I find the 3pt hitch to be sufficient (I would like a little more tractor size for the logging winch, but it is ok). I have enjoyed the Kubota a lot, just looking for a cab and a little larger loader capacity. I would recommend a reversible cutting edge on the bucket and a removable toothed bar they make a difference while digging and the edge helps with the strength of the bucket.
Good luck,
Mike
