Combines 1020 pully size from 1 5 to 3inIJ

There are actually 4 different pulley sizes available. You need to look at the pulley at the rear of the header that runs the wobble box. If it measures 9-5_8" OD, it runs the cutter bar at 460 rpm which is only for the 1.5". The 3" sickle takes a 10-1_2" pulley for 500 RPM. There is an optional pulley for the 3" sickle that runs 600 RPM which measures 12-1_2" OD, but I think it is pretty rare and probably puts extra stress on the wobble box. I suggest ordering the 10-1_2" pulley (1316047C1) for use with the 3" sickle. It uses the same belt as the 9-5_8" pulley (247428A1).

I have 3 differant used pulleys for a 1020 .let me know what size you need and i'll see if I have it . located in central Il. steve
