What causes mower to slow down after 45 min. of use and continues to operate after it cools down.

Joe Frias, June 2008

At the time that you suspect the machine to start slowing up, check the temperature of the engine and drive belts in case they are overheating. At the same time, check the temperature of the hydro transmission - these usually have a cooling fan built into them above the transmission and it often gets clogged with grass.
