# How to Check Fluid in a Craftsman Hydro Transmission
Craftsman riding lawn mowers use a hydrostatic transmission to help the motor and other controls work properly. If you notice that the control lever or other controls in the mower start to stick or malfunction, there could be a problem with your transmission. First make sure you have enough hydro transmission fluid from the real axle of your mower.
