Why Toro T4240 loses power after starting?
- D
  Dawn MorganSep 4, 2025
  If your Toro Lawn Mower loses power after working fine initially, the cause may be a worn pump or motor (replace parts as needed). The hydraulic oil level could be low (fill the hydraulic oil tank to the correct level). The oil in the hydraulic system might have the wrong viscosity (replace the oil with the correct viscosity-grade oil). A blocked oil-filter element (change the filter element) or a malfunctioning pressure relief valve (have the relief valve cleaned and pressure checked) are also potential causes. The system may be overheating (check the cylinder-to-bottom-blade adjustment and reduce the work rate by increasing the height of cut or reducing the forward speed). Finally, check for leaks on the suction hose and tighten the fittings, replacing the hose if necessary.

What causes excessive hydraulic noise in Toro T4240 Lawn Mower?
- C
  Cindy RileySep 6, 2025
  If there's excessive noise in the hydraulic system of your Toro Lawn Mower, identify and service or replace any malfunctioning pump or motor. Air leaking into the system can also cause noise, so tighten or replace the hydraulic fittings, especially in the suction lines. Check for a blocked or damaged suction strainer; clean or replace it as necessary. Cold conditions can cause the oil to have excessive viscosity, so allow the system to warm up. A low relief valve setting (have the relief valve pressure checked) or low hydraulic oil level (fill the hydraulic oil reservoir to the correct level) can also contribute to the noise.

Why my Toro T4240 won't move?

  If your Toro Lawn Mower isn't moving in either direction, start by checking if the parking brake is engaged and release it. Ensure the oil level is correct by filling the reservoir. Verify the reservoir has the correct type of oil; if not, drain and refill. Inspect the drive pedal linkage for damage and replace any worn parts. Other potential issues include a damaged transmission pump (have it overhauled), an open transmission bypass valve (close it), a broken drive coupling (replace it), or a blocked transmission filter (replace it).

How to improve contour following on Toro T4240?
- J
  Joshua JuarezSep 8, 2025
  If the cutting units on your Toro Lawn Mower aren't following the ground contours, check the hose routing and hydraulic fitting orientation, ensuring there's no tightness when moving the cutting units. Tight pivot points can also be a factor; release and grease them as needed. Make sure the machine isn't being operated in the ‘hold’ position; switch to ‘down / float’. Finally, if the weight transfer is too high, reduce it.

Why is one Toro Lawn Mower cylinder rotating slowly?
- B
  Brittany LeeSep 9, 2025
  If one cylinder on your Toro Lawn Mower is rotating slowly, it could be due to a seized cutting cylinder bearing (replace the bearings). Check if a motor with incorrect rotation was installed and replace it if necessary. The motor integral check valve might be jammed open (have it cleaned and checked). It's also possible that the cutting cylinder is too tight on the bottom blade (adjust the setting), the motor is worn (replace the motor), or the diverter valve is only partly open (free off and lubricate or replace the diverter valve).
