How to fix slow cutting unit lift on Toro Lawn Mower?
If the cutting units on your Toro Lawn Mower lift too slowly, it could be because the rear camshaft is misadjusted; adjust the camshaft. The #1 spool travel may be restricted by the mow/lift switch, so adjust the switch. Alternatively, the lift check poppet in the #1 spool section might be stuck partially closed; remove the lift check and repair or replace it.
Why is there no #1 or reverse speed on my Toro 04351?
If your Toro Lawn Mower's hydraulic system has no #1 or reverse traction speed, but #2 speed is normal, it could be due to a damaged or missing disc seal between the #3 and #4 valve sections; remove the valve bank and replace the disc seal. Another possibility is that the poppet inside the #4 spool is stuck open or off its seat; in this case, remove the valve bank and repair the #4 spool section.

If the cutting units drop during transport, a lift cylinder may be leaking internally, the lift check plug seals in the #1 spool body could be damaged, a detent stud may be loose in the #2 spool, or the #1 spool might be loose in the valve body. Raise the units and block them up. Remove the lines from the brazed tube and remove the blocks. The line that leaks fluid is attached to the bad cylinder. Repair the cylinder. Replace the o-ring assemblies. Tighten the stud with a screwdriver. Replace the spool valve assembly.
