If the cooling fan on your Toro Lawn Mower always rotates at a fast speed, inspect the proportional relief valve (PRV) for faults and replace it as necessary.
Why is the hydraulic system on my Toro 30479 operating hot?
If the hydraulic system in your Toro Lawn Mower is operating hot, there could be several reasons. First, increase the engine RPM. Ensure the brakes are not applied or sticking; release or fix them if they are. Refill the hydraulic reservoir if the oil level is low. If the hydraulic oil is contaminated or incorrect, replace it with the correct type. Other potential causes include an open or damaged piston pump bypass valve (repair or replace it), a cooling system not operating properly (fix or replace components), low charge pressure (check and adjust), incorrect traction circuit pressure (check and adjust), or damaged pumps or motors (repair or replace them).
Why is hydraulic oil in reservoir foaming in my Toro Lawn Mower?
If the hydraulic oil in the reservoir of your Toro Lawn Mower is foaming, it could be due to a low oil level in the hydraulic reservoir; if that's the case, refill it. It may also be caused by using the wrong type of oil in the hydraulic system, so replace it with the correct hydraulic oil. Another possible cause is air leaking into a pump suction line, so seal any air leaks in the pump suction line.
What to do if my Toro Lawn Mower has lost traction power or won't operate?
If your Toro Lawn Mower is losing traction power or won't operate in either direction, start by refilling the hydraulic reservoir oil if the level is low. Other possible causes include an open or damaged piston pump bypass valve (repair or replace it), low charge pressure (check and adjust), low traction circuit pressure (check and adjust), or damaged front wheel motor couplers (repair or replace them).
