  Joel NguyenAug 13, 2025
  To address an engine that won't start manually on your DR Trimmer Mower, consider the following: For the PRO model, ensure you are priming correctly by pushing the primer bulb 3 to 5 times, releasing fully each time. Use fresh, clean gas, and if the gas is old, replace it, using a fuel stabilizer for storage longer than two weeks. Check that the engine has the correct amount of clean oil, replacing it if dirty, following the engine manufacturer's manual. Inspect the spark plug to ensure it is clean; replace it if fouled or cracked, and if oily, clean the cylinder. Also, ensure the air filter is clean and replace it if needed, following the engine manufacturer's manual. Finally, verify that the throttle cable is correctly attached to the engine and moves freely.

  If your DR Trimmer Mower's engine won't start using the electric-start, first check all the items listed under manual start. Then, verify that your battery is charged, either by checking it yourself or at a gas station. If the battery is low, charge it using a 12-volt, 1.5 to 2 amp trickle charger. If you only use your DR® for short periods of about 45 minutes, the battery may need periodic charging.

Why dr trimmer mower Lawn Mower trimmer head won't spin?
- C
  Connie SmithAug 25, 2025
  If the trimmer head on your DR Trimmer Mower won't spin, make sure the trimmer head control is fully engaged. Pull the bail bar back to the handlebar and push the trimmer head control lever down until you hear a click. When released, it should spring part way back, and the head will spin as long as the bail bar is held. Also, check that your v-belt is properly aligned according to the diagram in the Belt section. Ensure the belt is inside idler pulley #1, the springs on the idler pulley arm and triangular brake actuator are in place, and the actuator moves when engaging the trimmer head control lever. Inspect the v-belt for wear or fraying and replace if necessary. Finally, check the condition of your bearings.

  Angela WilliamsAug 28, 2025
  If the trimmer head keeps spinning on your DR Trimmer Mower, ensure the trimmer head control is disengaging properly. When you release the bail bar, the control lever should come all the way up against the bar. Check the sleeve on the trimmer head control cable for clogs and clean it, then spray FLUID FILM® on the cable. Verify that your v-belt is correctly aligned, ensuring it's inside idler pulley #1 and that the springs on the idler pulley arm and triangular brake actuator are in place, with the actuator moving when the trimmer head control lever is engaged. Inspect the brake pad for wear and ensure the spring is intact.

How to prevent cutting cords from breaking on dr trimmer mower Pro?
- D
  Dalton VanceAug 31, 2025
  If the cutting cords on your DR Trimmer Mower are breaking, ensure they are not dry by storing them in a plastic bag with a damp sponge or soaking them in water for a few days. Avoid trying to cut too much too fast; ease into the material, allowing the cord tips to do the work, and take small bites of tall or tough vegetation. Consider using a lighter cord. Avoid hitting the cords against stone or chain-link fences, as this will cause them to wear out more quickly. Focus on controlling the cutting pattern to avoid obstacles.

Why are the cutting cords pulling out of my dr trimmer mower Lawn Mower?
- M
  Morgan JenkinsSep 4, 2025
  If the cutting cords are pulling out of your DR Trimmer Mower, avoid moving too fast into tough, woody growth, which can cause the cords to wrap and pull out. Check the operating tips in the section on breaking cords. Ensure you are not trying to cut material too heavy for the cord; the DR® is designed for green material up to about the thickness of a pencil. For heavier material, consider using the BEAVER BLADE® attachment. Check if you are installing the smaller cord in the larger openings.

Why is parallel trimming action difficult on my dr trimmer mower Pro Lawn Mower?
- J
  Justin HernandezSep 8, 2025
  If you're finding Parallel Trimming Action difficult on your DR Trimmer Mower, check if the axle is binding when you shift into PTA mode and spray FLUID FILM® at the points where the axle slides on the frame. Ensure the self-locking nut over the bolt that holds the flat end of the PTA lever to the latch is not too tight; loosen it 1/4 turn at a time until the PTA works smoothly. Also, check if the axle nut under the frame is too tight and loosen it a bit if necessary.
