Guys.....I have noticed that on the Super A the planter drive (on the final drive) is different from a 140. I sold the Super A and got this 140 and now have found a planter for it. I am wondering how I can attach the planter drive gear to my tractor because the Super A had an oil seal that came with the drive once removed from the final drive. My friend down the street has a 140 and it looks like to me that the seal is built into the final drive so when you remove the gear drive it won't work....basicaly you have to leave the round gear drive stub on the tractor? Did all 140 tractors come with the gear drive stub or did someone remove mine? No wonder oil is leaking there!
