: TRACTOR TURNS EASY TO THE RIGHT, BUT IT TAKES A VERY STRONG PERSON TO TURN IT TO THE LEFT. ANY SUGGESTIONS ON WHAT TO DO? Had this problem many times on the smaller machines (M, 40, 420). There is a worm gear and a yoke with one or two pins that ride in the worm gear. The worm is on the steering box input shaft, and the yoke is on the output shaft. What happens is the pins become loose, and wear an oval hole in the yoke. In the direction the machine was turning the most for many year (farmers like to turn right in the fields for some reason). The pins follow in the worm well in that direction, but the pins bind on the worm in the opposite direction. Opposite steering does get easier the farther it's turned. The solution, I've found, is to disassemble the steering box and mill out the holes in the yoke. Then, fabricate new pins, or build up the old ones and cut to fit. I use a press fit and tack weld the ends to hold them in. Perhaps new parts are still available, but since I have a machine shop I find it easier to repair than replace......
