I have calculated the DRAG RATIO of my L3200 to 1.5526, based on the gear teeth in the parts manual. Does anyone know if this is really correct? It seems to work OK with the tire movement.
How about the L4600? I may want to try their larger tires / wheels someday, but am not sure about the ratios. This would be about $1300 based on EBAY prices.

According to Kubota specs the lead ratio is 1.55 on the L3200 and 1.57 on the L4600..

Thank you!
Now, according to my understanding you want the tire diameter ratio to be a bit less than the drag - or lead - ratio; you want the front tires to be trying to pull the back tires. Again, this works with the L3200.
The ratios on the L4600 work out just the opposite. The tire ratio is larger than the drag ratio! Actually, about the same for the ag tires, but over 1.60 for the industrial. Am I misunderstanding something? It must work OK in the real world....
Thanks again...
