I'll put my list in here too:
'41 Farmall A dual fuel with vacuum lift
Kubota B1600
Massey 1085 Cab
JD 4020 Diesel Powershift open station
Kubota M9000 HDCC3
Lets see, I've owned them all. Wish I still had the '41 barnyard Buick, I still have the single bottom plow in my barn, someday to be a yard ornament I suspect.
The JD, well I sold it. It was open station as well as the little Kubota which was my first of many Kubota's. Open station units don't cut it with me. I like comfort, air and a good stereo.
I still have the Massey 1085. It's a beast with the 12x12 combined multi power transmission and the 318 cubic inch Perkins naturally aspirated diesel. It's also heavy and tall but it goes down the road fast enough to get me a ticket in a school zone. I've dead yanked a few 5" diameter maples with the 1085 and never spun a wheel and they aren't loaded (I don't believe in loading tires). She is good on fuel too.
I just bought the M9000. My partner has a 105S and I fell in love with the tractor. My little 5030 was a toy compared to the 105 but the 105 is ungainly like the 1085. My alternative was the M9. Plenty of torque rise with the turbo/ata motor and a square hood with an honest to goodness hood ornament for me to line up my rows with. I had a bad time getting straight rows with the 105.
I like old iron, problem is, I use my tractors for their intended purpose and when it's time to farm I don't want to be tinkering.
Besides, I live in Deere country and it's refreshing to see silver and red or orange and grey going down the road
