There are two variants of the JX-75, early and late. This is a replacement propulsion drive pulley for the early series machine, JD part number AM107567. 3-1/2" outer diameter, 10mm shaft, 3mm key. (The newer version uses a 4" drive pulley). It is not an exact copy of the original metal pulley. It is functionally equivalent -- dimensions are tweaked to suit 3D printing.
Printed in carbon fiber Nylon (PA-CF). Supports are required as well as a little post-processing to smooth out the v-groove walls and minimize belt wear. Starting its second season of use and still holding up perfectly, even pulling up hill with a full grass-catcher.
Fully parametric. FreeCad design file included.
