What to do if the hydraulic fluid foams excessively in my Toro Groundsmaster 3280-D Lawn Mower?
- DDr. Sharon ChambersAug 25, 2025
Excessive foaming of hydraulic fluid can stem from several causes. The hydraulic fluid level in the reservoir may be low, the system may contain the wrong type of fluid, there may be an air leak in a pump suction line, incompatible hydraulic fluids might be mixed, or there could be water in the hydraulic system. To resolve this, fill the hydraulic fluid reservoir to the appropriate level, change the hydraulic fluid to the correct type, inspect and repair the pump suction line for air leaks, drain the system and refill with compatible hydraulic fluid, or drain the system and remove the water.
