What to do if DR PRO-XL 44T engine lacks power or is not running smoothly?

  georgewaltersAug 18, 2025
  If your DR Lawn Mower engine lacks power or isn't running smoothly, check the Throttle Lever to ensure it's in the RUN position. The Air Filter, Spark Plugs may be dirty or cracked and should be changed. If the Spark Plug is oily, remove it, hold a rag over the plug hole, and crank the engine to blow out oil, then clean and reinsert the plug. Make sure the gas is fresh and clean. If the gas is old, replace it. Also, ensure the engine has the correct amount of clean oil; if it’s dirty, change it.

  Robin ThomasAug 21, 2025
  If the blades vibrate when engaged on your DR Lawn Mower, first ensure the Blade Carrier Mounting Bolt is tightened as much as possible by hand with a 1ft long 1-1/8" Wrench. Also check if a Swinging Blade is too loose on the Blade Carrier and re-tighten its mounting hardware. Replace any Swinging Blade that is chipped, bent, or broken. The Spindle Bearings may be damaged or the Spindle Shaft may be bent.

Why is my DR PRO-XL 44T Lawn Mower engine smoking?
- M
  Michael HughesAug 31, 2025
  If your DR Lawn Mower engine is smoking, start by checking the oil level and adjust as needed. It's possible you're operating the machine on too steep of an incline. Inspect the Air Filter and clean or replace it if necessary. You might be using an oil that's too light for the current temperature. Also, ensure the Cooling Fins and Carburetor housing are clean.

  If the blades on your DR Lawn Mower won't engage or disengage, the Blade Control Switch may be faulty and needs to be replaced. A low or weak battery may cause electric clutch to not engage, so check battery for sufficient voltage.
