For Sale: I believe it is a 50, RD7, D7 belt pulley gear box. The input shaft was sawed off. The pulley, breather, and shift lever is missing. It turns ok. Gears have some wear, not sure about bearing condition. Good for parts or repair. $175.00 or make an offer. You pick up or possible delivery to Le Sueur. I'm in MN. Give me a call 320-654-9511
