Why one cutting deck will not operate on my Toro 30446?
- T
  Thomas AriasSep 5, 2025
  If one cutting deck on your Toro Lawn Mower will not operate, check and adjust the system pressure to the affected deck if it's low. Other potential causes include a damaged Woodruff key on the affected deck motor (replace it), a faulty solenoid valve (S) in the deck manifold (replace it), a damaged or sticking cartridge valve in the deck manifold (repair or replace), or a damaged deck motor or gear pump section (repair or replace).

Why is the hydraulic system on my Toro 30446 operating hot?
- T
  Tiffany BennettAug 25, 2025
  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 30446 Lawn Mower?
- B
  Bobby GomezAug 26, 2025
  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 30446 Lawn Mower has lost traction power or won't operate?
- J
  James LopezAug 27, 2025
  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).

Why cutting decks will not raise on my Toro 30446 Lawn Mower?
- J
  Jessica MorganAug 27, 2025
  If the cutting decks on your Toro Lawn Mower won't raise, first, increase the engine RPM if it's too low. If the hydraulic oil level in the reservoir is low, refill it. Check for binding lift arm pivots and free or repair them if necessary. Other potential issues include a stuck relief valve in the lift/lower control valve (repair or replace), a damaged or sticking pilot valve in the lift/lower control valve (repair or replace), damaged lift cylinder(s) (repair or replace), or an inefficient gear pump section for the lift/lower control valve (repair or replace).

Why my Toro 30446 operates in one direction only?
- A
  Anthony WeaverAug 28, 2025
  If your Toro Lawn Mower only operates in one direction, the issue might be a faulty traction control linkage; in that case, repair or replace it. Alternatively, the traction relief valve could be defective, requiring replacement.

Why cutting deck stops under load on my Toro 30446?
- A
  Angela BautistaSep 6, 2025
  If a cutting deck on your Toro Lawn Mower stops under load, the relief valve in the deck manifold may be bypassing; repair or replace it. Alternatively, the deck motor may have internal leakage, or the cutting deck gear pump section may be inefficient; repair or replace these components as needed.

Why no cutting decks will operate on my Toro 30446 Lawn Mower?
- J
  Joseph HarrisSep 4, 2025
  If all the cutting decks on your Toro Lawn Mower won't operate, the gear pump or its coupler may be damaged; repair or replace the damaged gear pump or coupler.

Why all cutting decks operate slowly on my Toro Lawn Mower?
- R
  Rachel LewisSep 2, 2025
  If the cutting decks on your Toro Lawn Mower are operating slowly, increase the engine RPM if it's low. Damaged deck motor or gear pump sections could also be the cause, so repair or replace them.
