Early ZD's did have problems with mowing side hills with the hydro's. Kubota did offer a kit at the time to increase the oil reservoirs to eliminate the problem and it seems to work. Hour limits on many of them are well beyond many, we have a ZD323/60 over 7,000 hours and we have more in the 4,000 to 6,000 hour range professionally used with no component failures.
