Why is the cutting height uneven on my Toro 74945?
Uneven cutting height on your Toro Lawn Mower can stem from several issues. Start by sharpening the blades. If a cutting blade is bent, install a new one. Ensure the mower is level from side-to-side and front-to-rear. If applicable, check that the anti-scalp roller is set correctly and clean the underside of the mower deck. Finally, verify that the tire pressure is correct.
How to fix a Toro Lawn Mower engine that loses power?
If your Toro Lawn Mower engine is losing power, it could be due to several reasons. First, check if the engine load is excessive and reduce the ground speed. A dirty air cleaner can also cause power loss, so clean the air-cleaner element. Ensure that the oil level in the crankcase is adequate, adding oil if necessary. Additionally, inspect the cooling fins and air passages above the engine for any obstructions and remove them. Lastly, the vent hole in the fuel cap may be plugged, so clean or replace the fuel cap.
What to do if my Toro 74945 engine does not start?
If your Toro Lawn Mower engine doesn't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel-shutoff valve is open. Check that the oil level in the crankcase is sufficient and the throttle is positioned midway between the SLOW and FAST settings. Also, a dirty fuel filter or air cleaner can cause issues, so replace or clean them as needed. Inspect the spark plug, adjusting or replacing it if it's fouled or improperly gapped, and verify the spark-plug wire is securely connected. Finally, check the seat-switch indicator, replacing the seat if necessary.
Why Toro 74945 blades do not rotate?
If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken mower deck belt; in this case, install a new deck belt. Also, check if the mower deck belt is off a pulley and install the mower deck pulley, checking the idler pulley, idler arm, and spring for correct position and function. Inspect the pump drive belt for wear, looseness, or breakage, and check the belt tension or install a new belt. If the idler spring is broken or missing, replace it.
Why does the malfunction indicator light (MIL) come on in my Toro 74945 Lawn Mower?
The malfunction indicator light may activate for several reasons. It could be due to the engine overheating, in which case you should shut it off and allow it to cool. Other potential causes include using old fuel (replace with new fuel), a fuel-shutoff valve that isn't fully open (open it completely), a dirty air cleaner (clean or replace it), a discharged battery (charge or replace it), low battery voltage (ensure you're using a fully charged 12V battery), or a blown fuse (check and replace any blown fuses).
What to do if my Toro 74945 machine does not drive?
If your Toro Lawn Mower isn't driving, it could be because the bypass valves aren't closed tight, the pump belt is worn, loose, or broken, the pump belt is off a pulley, the idler spring is broken or missing, or the hydraulic oil level is low or too hot. Try tightening the bypass valves, changing the belt, replacing the spring, or adding hydraulic oil to the reservoirs or letting it cool down.
What causes my Toro 74945 to vibrate abnormally?
Abnormal vibrations in your Toro Lawn Mower can stem from several sources: bent or unbalanced cutting blades, a loose blade mounting bolt, loose engine mounting bolts, a loose engine pulley, idler pulley, or blade pulley. To resolve this, install new cutting blades, tighten the blade mounting bolt, tighten the engine mounting bolts, and tighten the appropriate pulley. For issues related to a damaged engine pulley, bent blade spindle, or a loose/worn motor mount, contact an Authorized Service Dealer.
What to do if Toro Lawn Mower clutch does not engage?
If the clutch on your Toro Lawn Mower isn't engaging, several things could be the cause.

Low voltage supply at the clutch can also be a factor, so check the coil resistance, battery charge, charging system, and wiring connections and replace parts if necessary. If the coil is damaged, replace the clutch. Inadequate current supply can also cause this, so repair or replace the clutch lead wire or electrical system, and clean the connector contacts. Finally, if the rotor/armature air gap is too large, remove the shim or replace the clutch.
