Then Cub Cadet used the Hydro-Gear hydro pump on models like the 1440, some 1541's, 1641, 1861 & the 1863's. I believe those machines were priced a little cheaper than models with the Sunstarnd pumps when new.

One can change the Sundstrand output shaft gear, but it requires disassembly of the hydro.
There is one tooth difference between them, with the super having one tooth less than the non super models, as it makes up for the larger rear tires on the super making for the same in overall speed of the tractors.
