Top 10 Common Lawn Equipment Issues (and How to Fix Them for a Healthy New Hampshire Lawn)

problematic lawn

New Hampshire summers are short—but packed with yardwork. July is when homeowners and landscapers in the Granite State put their mowers, trimmers, blowers, and edgers to the test. And unfortunately, it’s also when the most common lawn equipment issues start to show up.

At Seacoast Power Equipment, we repair hundreds of machines every July—many with the same handful of issues that could have been avoided with simple maintenance or early detection. In this guide, we’ll walk through the top 10 lawn equipment problems we see most often, how to troubleshoot them, and what you can do to keep your lawn tools in peak condition.

Whether you’re maintaining your lawn in Portsmouth, Dover, Rochester, or anywhere along the Seacoast, this is your go-to resource for staying ahead of summer equipment breakdowns.


1. Lawn Mower Won’t Start

Common reasons include:

  • Stale fuel
  • Dead battery
  • Faulty spark plug
  • Clogged air filter

Try replacing old gas, inspecting the spark plug, and cleaning or replacing the air filter. If that doesn’t work, schedule a visit to our lawn mower repair service for professional help.


2. Uneven Mowing or Scalping Spots

This issue is often caused by:

  • Dull or misaligned blades
  • Improper deck height
  • Low tire pressure

Our seasonal tune-up services include blade sharpening and deck leveling to ensure a clean, even cut every time.


3. Excessive Vibration During Use

Vibration is often a sign of:

  • Bent blades
  • Loose hardware
  • Engine mount issues

Catch these problems early with a quick visit to our equipment diagnostics and repair shop. We handle all makes and models with same-day turnaround on many repairs.


4. Trimmer Line Keeps Breaking or Jamming

Frequent trimmer line issues stem from:

  • The wrong line diameter
  • Poor spool winding
  • Debris buildup

We carry professional-grade replacement lines and provide fast service for string trimmers. Visit our parts department or swing by for expert help.


5. Leaf Blower Loses Power Mid-Use

Gas-powered and battery blowers both experience power loss due to:

  • Incorrect fuel mix
  • Dirty spark plugs
  • Old or damaged batteries

Our leaf blower repair experts can quickly clean, flush, and replace key components to restore full power.


6. Battery Equipment Won’t Hold a Charge

Battery-powered mowers, trimmers, and blowers can fail due to:

  • Aging lithium-ion cells
  • Corrosion on terminals
  • Improper winter storage

We stock OEM batteries for Kress, Stihl, and Husqvarna equipment and can test yours before you invest in a new one.


7. Starter Rope is Stuck or Retracts Slowly

Recoil starters jam from:

  • Rusty or dry springs
  • Dirty housings
  • Fraying cords

If your pull cord isn’t working smoothly, stop by our shop for a quick inspection. We handle hundreds of small engine repairs every month across all common outdoor tools.


8. Oil Leaks Under Equipment

If you notice oil pooling under your mower or edger, the cause might be:

  • Overfilled oil reservoirs
  • Worn seals or gaskets
  • Incorrect equipment storage

Our seasonal maintenance service includes oil changes, seal inspection, and cleaning to prevent long-term damage.


9. Worn Tires or Poor Traction

You may need to replace tires if:

  • The tread is smooth
  • You experience slippage on hills
  • The tires dry rot from sun exposure

10. Depth Adjustment Issues on Lawn Edgers

If your edger isn’t producing clean, even cuts:

  • The blade may be misaligned
  • The adjustment knob may be stuck
  • The shaft could be bent

These precision issues are best left to our trained service techs, who can recalibrate your edger and get you back to crisp, clean lines.
