We have a John Deere 450 and have track - drive sprocket coordination problems after we purchased a new track. The new track is approximately 6.125" spacing center of pin to center of pin, and the drive sprocket is approximately 6.0". The result is that the track rides up on the pins as there's a 1/2" gain every four drive sprocket teeth and then there's a snap when the chain goes over the top of the teeth. This obviously is going to create a lot of wear and tear on the track (and sprocket). Does anybody have experience with 6.0" 450 drive sprockets? Thank you, and have a good day.
