I just bought a Standard Kingkutter 4' and I had the same problem with the lower plug on the gearcase, Manual says to add oil to the plug hole, good luck with that! Well I had to use the dipstick measure also. How easy was yours to mount on your 3 point? I took off upper 3 point to get it mounted and they are spread as far as they will go, On my 5' blade i was able to turn the pins inward which was easier to hook up.
