Mine finally broke apart. Looking to see if anyone has a knob or lever with the knob. Alternately would like to know if anyone knows of a suitable replacement know. It looks to me like the knob was is not replaceable and the military probably just replaced the whole PTO lever if the knob broke. If I can't find any thing I might have my son 3d print one or we might make a mold to mold a new one around the lever.
