I've been running hydro cubs since the late 60's starting with a 105 my dad bought from a neighbor ,still running with no issues at all with the hydro. It's plowed gardens,plowed snow ,rototilled,cultivated & mowed acres of grass by myself and my sons cutting lawns in their teens ! I like the hydros because you have constant speed control,every manual tractor I've had usually needed a clutch at some point, or wanted to jump out of gear, and for mowing it always seemed 1st gear was to slow and second to fast ,just my thought but I like the hydro's !
