Although I grew up on a 1946 Farmall M (still have it) and a big Case LA, I did drive a neighbors JD B on the hay and straw rake. I always thought the hand clutch was cool - also on the LA. A cousin was an Allis fan and had the WD, WD-45, D-17, and a little B. That B had a belly mount sickle bar mower that I rolled over with about 1957 or so, no injury, just pulled the B back up from the edge of a pond....
Our M was re-fitted with M&W Crater Head Pistons, 2-way hydraulic and widened rear rims to take 15.5X38s. Before the mod it pulled 2-18s. After the mods we went to an Oliver 3-16 with a packer. The LA pulled a JD 5-16 with packer. I spent many a night plowing with the whole radiator on the LA glowing in the dark.
Our corn planter was a pair of horse drawn 2 rows rigged up on a "double tree" to pull with the M. We later bought a JD 494A 4 row. I sold the planter about 5 yrs ago for $50 to a neighbor/collector in Indiana.
The combine was a JD 12A, 2 cyl Wisconsin engine, 6 ft bed with canvas feed. The hardest starting engine I've ever hand cranked! At least that wasn't as bad as a neighbor's Moline(?) combine that allowed only a 3/4 turn of the crank. I remember seeing it dead in the field for hours at a time....
