The annoying story of the fluid drives

Once you get used to the fluid drive and recognize its limitations, it’s useful. Once in third, you can leave it there and not use the clutch or shift.

Smooth operation in a field while hauling hay. Smooth operation in stop and go traffic. Smooth operation on long, slow back road drives.
Easy to see why it was popular in old cabs. Just don’t park carelessly on inclines.
