I was considering putting the pto, hoist, 2 speed rear end, and deluxe 5 window cab on the 4100. I don't have a title for the 6400. I think I could fight my way through the Iowa legal system and get a title for it but the 4100 already has a good title. What do you guys think. The 6400 has a 235 with inserts and full pressure. The 4100 has a 216 and babbitts.
