  If the hydraulic fluid in your Toro Lawn Mower is foaming excessively, causing leakage from the hydraulic tank breather, consider the following: The hydraulic fluid level in the hydraulic tank may be low, so fill it to the proper level. The hydraulic system might contain the wrong type of fluid, in which case you should replace it with the correct type. There could be an air leak in one of the pump suction lines, so inspect and repair any leaks. Incompatible hydraulic fluids might be mixed in the system; drain and replace the hydraulic fluid to resolve this. Finally, there might be water in the hydraulic system, so drain and replace with dry hydraulic fluid.

  If the wheel motor on your Toro Lawn Mower doesn't turn, consider these potential causes: The brakes might be binding, so inspect and fix them. Alternatively, the piston (traction) pump bypass valve could be open, so check, repair, or replace it. Lastly, the piston (traction) pump or the wheel motor itself might be worn or damaged; in this case, inspect and repair or replace the affected components.

  If the steering on your Toro Lawn Mower is inoperative or sluggish, there are several things you can check: worn or binding steering components (inspect and repair), a binding steering cylinder (inspect and fix), a low fluid level in the hydraulic reservoir (fill to the appropriate level), a stuck or damaged steering relief valve (inspect and repair or replace), internal leaks in the steering cylinder (inspect and repair), a worn or damaged steering control valve (inspect and repair or replace), or a worn or damaged gear pump section (inspect and repair or replace).
