Frequently Asked Questions
Why won't my hydrostatic transmission move?
Non-movement indicates bypass levers engaged in freewheel position, air in hydraulic system, failed drive belts, extremely low fluid levels, or completely failed pumps/motors. Check bypass levers first eliminating simplest causes.
How do I service sealed hydrostatic transmissions?
Sealed transmissions require complete removal, draining through vents with unit inverted, refilling with 20W-50 oil through vent whilst upright. Manufacturer discourages this; service sometimes extends life 100-200 additional hours.
What causes one side of zero-turn to be weak?
Weak side indicates low fluid in that transmission, air in hydraulic system, worn pump allowing bypass, slipping drive belt, or damaged motor components. Often signals transmission approaching end of life.
How long do Snapper hydrostatic transmissions last?
Consumer-grade sealed transmissions (EZT-type) typically last 300-600 hours before failure; commercial units with serviceable oil last significantly longer with proper maintenance. Usage intensity directly impacts longevity.
Why does transmission work cold but fail hot?
Hot-failure indicates worn internal components allowing fluid bypass when heated reducing hydraulic pressure dramatically. Fresh oil sometimes helps temporarily but typically signals imminent transmission failure requiring replacement.
