Why won't the wheel motor on my Toro Groundsmaster 3505-D Lawn Mower hold load in neutral?

If the wheel motor on your Toro Lawn Mower will not hold a load in neutral, it could be because make up fluid from the charge pump is not available, or the hydrostat ball check valves are damaged. Ensure make up fluid from charge pump is available and inspect and replace damaged hydrostat ball check valves.
