You're comparing apples and oranges unless the Branson uses the exact same components. That's like saying my old Ford 300 six went 500,000 miles without a problem so my Yugo should as well. Sometimes a clutch and gearbox is a better option than a hydrostat especially when it comes to repairs. Depending on the machine if a hydrostat goes out it can be worth more than the machine to fix. Hydrostatic transmissions are very pression components and 1 spec. of dirt can destroy them. If it's hard to find a filter, how hard is it to find other parts or people who work on them?
Ty....I assumed that hydrostatic transmissions were much simpler then those that used clutch, gears. The hydro pump on my Terramite seemed to be very simple and reliable.
