I've driven 200 or more tractors. My top 3 in reverse order are:

3) a 1988 Ford 4610 with 4wd, AP cab and H pattern syncro.

2) the 2000 Case MX135 I had for 8 years

1) the 2 Massey 7618 Dyna VT's I drive at work. The main one I drive has just gone in for a "service opportunity" to sort out some age related ailments, but will doubtless come home in tip top condition and I'll likely get moaned at for the cost, but they've all had 2 tractors in the time I've had that one and it's still doing more work than their's that are double the size, so meh.
