I spent many an hour riding the seat of my dad's Super M-TA. For a long time it was our only tractor with a four row cultivator. I graduated to it from the John Deere B and it's two row cultivator. After a while though you began to wish it had power steering and real brakes. With a front mounted IH 461 cultivator it was a pain to turn at the end rows. The drum brakes just didn't have the strength to lock the wheel like the B would. The M-TA was a good tractor and did it all. Your pictures bring back a lot of good bittersweet memories. Dad's was a narrow front end with swinging drawbar. I spent a lot of time in June and July as a teenager in Eastern Iowa on the M-TA cultivating corn and soybeans
