Why is my Husqvarna 7021R Lawn Mower losing power?
- E
  Erika MarshallJul 26, 2025
  A loss of power in your Husqvarna Lawn Mower can stem from several causes. First, check if the rear of the mower housing or blade is dragging in heavy grass and raise the cutting height. Also, ensure you're not cutting too much grass at once, which also requires raising the cutting height. Other potential issues include a dirty air filter (clean or replace it), a buildup of grass under the mower (clean the underside), too much oil in the engine (check the oil level), or walking too fast (reduce your walking speed).

  An uneven cut with your Husqvarna Lawn Mower can be caused by a worn, bent, or loose blade; replace the blade and tighten the blade bolt. Also, check if the wheel heights are uneven and set all wheels at the same height. Lastly, a buildup of grass under the mower can cause this issue, so clean the underside of the mower housing.

What to do if the starter rope is hard to pull on my Husqvarna 7021R?

  If the starter rope on your Husqvarna Lawn Mower is hard to pull, it could be due to several reasons. Make sure the engine flywheel brake is not engaged by depressing the control bar to the upper handle before pulling the rope. Also, the blade might be dragging in the grass, so move the mower to cut grass or another hard surface before starting. Finally, a broken blade adapter can cause this issue; in that case, replace the blade adapter.

Why is my Husqvarna 7021R Lawn Mower so hard to push?
- D
  David JohnsonAug 7, 2025
  If your Husqvarna Lawn Mower is hard to push, it could be because the grass is too high or the wheel height is too low; raise the cutting height. It could also be that the rear of the mower housing or cutting blade is dragging in heavy grass; raise the rear of the mower housing one setting higher. Another reason may be that the grass catcher is too full, so empty it. Finally, the handle height position might not be right for you, so adjust it to suit.

  Jeremy MurrayAug 17, 2025
  If the grass catcher on your Husqvarna Lawn Mower is not filling, it could be due to a few reasons. The cutting height might be too low, so raise it. The lift on the blade could be worn off, so replace the blade. Also, the catcher might not be venting air, so clean the grass catcher.

Why is the drive speed slowing or lost on my Husqvarna 7021R?
- M
  Mr. Jake WilsonAug 21, 2025
  If you're experiencing a loss of drive or slowing of drive speed on your Husqvarna Lawn Mower, the issue might be caused by belt wear, so check and replace the drive belt if necessary. It could also be that the belt is off the pulley, so check and reinstall the drive belt. A worn or broken drive cable can also be the culprit; put the belt on the pulleys or replace the belts if broken. Finally, a loose drive control system may be the cause, so adjust the drive control.
