    How to fix Poulan Pro PB20A46 that will not start?
    • E
      Eric OlsonAug 20, 2025
      If your Poulan Pro Lawn Mower won't start, several factors could be the cause. First, make sure the fuel tank is full. If that's not the issue, ensure the engine is choked properly, as described in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other potential causes include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or water in the fuel (empty the tank and carburetor, refill with fresh gasoline, and replace the fuel filter). Also, check for loose or damaged wiring. If none of these solutions work, the engine valves may be out of adjustment, and you should contact an authorized service center.

    • J
      Jerry ContrerasAug 22, 2025
      If your Poulan Pro Lawn Mower is hard to start, consider these possibilities: The air filter might be dirty, so clean or replace it. The spark plug could be bad, requiring replacement. A weak or dead battery could be the issue; recharge or replace it as necessary. Also, check the fuel filter; if it's dirty, replace it. Stale or dirty fuel can also cause problems, so empty the fuel tank and refill it with fresh, clean gas. Finally, inspect the wiring for any loose connections or damage. If these steps don't resolve the issue, the engine valves may need adjustment by an authorized service center.

      If the mower blades of your Poulan Pro Lawn Mower will not rotate, there might be an obstruction in the clutch mechanism; remove it. The mower drive belt could be worn or damaged, so replace it. A frozen idler pulley or blade mandrel could also be the cause, requiring replacement.

    What to do if Poulan Pro PB20A46 Lawn Mower engine will not turn over?
    • J
      John ClarkAug 30, 2025
      If the engine of your Poulan Pro Lawn Mower won't turn over, make sure you're depressing the brake pedal. Also, ensure the attachment clutch is disengaged. A weak or dead battery could be the culprit, so recharge or replace it. Check for a blown fuse and replace it if necessary. Clean any corrosion from the battery terminals. Inspect all wiring for looseness or damage. If the problem persists, the ignition switch, solenoid, or starter might be faulty and need checking or replacement. If those don't solve the problem, contact an authorized service center to inspect the operator presence switches.

    How to fix Poulan Pro PB20A46 Lawn Mower poor uneven cut?
    • C
      Christopher ScottSep 1, 2025
      If your Poulan Pro Lawn Mower is leaving an uneven cut, the blade might be worn, bent, or loose; replace the blade and tighten the blade bolt. Check if the mower deck is level and adjust it if necessary. Buildup of grass, leaves, or trash under the mower can also cause an uneven cut, so clean the underside of the mower housing. Additionally, inspect the blade mandrel for bending and replace it if needed. Finally, check for clogged mower deck vent holes and clean around the mandrels to open them.

    Why Poulan Pro PB20A46 Lawn Mower has poor grass discharge?
    • S
      Sara WelchSep 3, 2025
      If your Poulan Pro Lawn Mower has poor grass discharge, ensure the engine speed isn't too slow by placing the throttle control in the 'FAST' position. If you're moving too fast, shift to a slower speed. Wet grass can also cause poor discharge, so allow the grass to dry before mowing. Check if the mower deck is level and adjust it if necessary. Make sure the tire air pressure is correct and even. Inspect the blade for wear, bending, or looseness, and replace or tighten it as needed. Clean any buildup of grass, leaves, or trash under the mower. If the mower drive belt is worn, replace it. Ensure the blades are installed with the sharp edge down. If improper blades are used, replace them with the blades listed in the parts manual. Finally, clear any clogged mower deck vent holes.
