There are several M Series owners so maybe you will get several answers. I started to buy the JD 5410 or the Kubota M8200 and decided on the M6800SD. Kubota makes a cab for all of their tractors. The M8200 was a little longer WB than what I wanted and with a 4WD, I could pull most any implement that a 100 HP would normally handle in a 2WD system. Search on
M6800, M8200, and M9000 on this board and in the archives and you will find quite a bit written about these tractors.
I found prices kinda hard to compare as Kubota comes with nearly all options installed (except the quick connect bucket or 2nd SCV), but I had to search a little harder to get the right sized tires, transmissions, SCV were used up by the loader, etc. on some of the other manufacturers.
The loader for M8200 is a heavier duty loader and uses a 7 ft bucket holding a tad over a yard. It is a 4 Bar level loader with a fast cycle time. Kubota has good hydraulics. I did my own 50 hour maintenance and don't expect any problems from Kubota, but they seem to have a good parts supply system and service departments. The
M6800 comes with two midmounted sets of valves for the loader and one external set on the rear. You will need another one for sure. The CAB is not unreasonably priced. There are some prices at
http://www.carverequipment.com including the cab models.
I could never find as much tractor for the money with JD, but there are at least two people here with the larger JD and NH as well as Kubota. The
M6800 runs about $27K with 4WD and loader and quick connect bucket in ROPS or $32K in CAB. The M8200 with 4WD and loader in ROPS is about $29K in ROPS or $35K in CAB.
My
M6800 with tires loaded and loader is less than 8000# and the WB is more maneuverable with enough HP for most Utility tractor applications. Average fuel consumption is about 1 gallon/hour which is about the same as my last 40 HP Massey tractor got. The M8200 was only about $1500 more when I bought mine, so there is not much cost difference. The CABS are really nice, and with 102 degrees here today, I still wish I had bought one. /w3tcompact/icons/smile.gif Both should be good haying machines and a lot more.
