A Quick Overview
The main reasons your lawn mower is hard to push typically stem from issues with the engine, the cutting deck, or the wheels. The mower might be struggling to power through tall grass, the blades might be dull or clogged, or the wheels might be damaged or not rolling freely. This article will break down each of these potential problem areas and offer tips on how to fix them.
The Engine: The Heart of the Matter
The lawn mower engine is the powerhouse that drives the blades and propels the machine forward. If the engine isn’t performing at its best, it can lead to a sluggish and difficult-to-push mower.
1. Fuel and Air Issues
- Old or Bad Gas: One of the simplest culprits is old or stale fuel. Gasoline degrades over time, losing its volatility and making it harder for the engine to combust properly. This can cause the engine to sputter and run poorly, making the mower harder to push.
- Clogged Air Filter: A dirty air filter restricts airflow to the engine, starving it of oxygen. This can lead to decreased power and a harder-to-push mower.
2. Spark Plug Problems
- Fouled or Worn Spark Plug: A spark plug that’s fouled with carbon buildup or worn out can prevent the engine from igniting the fuel mixture properly. This can result in a weak spark and a sluggish engine.
3. Engine Oil Issues
- Low Oil Level: Low oil levels can lead to engine damage, but even if the oil level is simply a bit low, it can affect performance, causing the engine to run hotter and struggle to generate power.
The Cutting Deck: Where the Grass Meets the Blade
The cutting deck houses the blades and is responsible for slicing through the grass. Issues with the cutting deck can directly affect how smoothly the mower pushes.
1. Dull Blades
- The Importance of Sharp Blades: Dull blades are one of the most common reasons for a hard-to-push lawn mower. They have to work much harder to cut the grass, straining the engine and making the mower feel heavy.
- Signs of Dull Blades: If you notice the grass being torn or shredded rather than cleanly cut, or if you see uneven cuts, it’s likely your blades are dull.
2. Clogged Deck
- Debris Build-up: Grass clippings, leaves, and other debris can accumulate in the cutting deck, blocking airflow and hindering the engine’s performance. This makes the mower harder to push and can even lead to overheating.
3. Deck Height
- Too Low of a Cut: If you’re cutting your grass too short, it can also make the mower harder to push. The engine will be working harder to cut through the thicker blades of grass, creating a heavier feel.
The Wheels: The Foundation of Movement
The wheels are responsible for keeping your lawn mower moving. Worn or damaged wheels can make the mower feel like it’s dragging its feet.
1. Flat Tires or Low Air Pressure
- Friction and Resistance: Flat tires or tires with low air pressure create a lot of friction and resistance, making it difficult to push the mower.
2. Damaged or Worn Wheels
- Wheel Bearings: Damaged or worn bearings in the wheels can create a rough and grinding sound and make the mower feel heavy to push.
Mowing Techniques and Other Factors
There are a few additional factors that can impact how hard your lawn mower is to push:
1. Mowing Technique
- Overlapping Passes: Always overlap your mowing passes by a few inches. This ensures you’re cutting all the grass and prevents scalping.
- Mowing Direction: Consider the direction you mow. Mowing uphill can be more challenging than mowing downhill.
2. Lawn Condition
- Thick and Long Grass: Mowing thick, long grass will naturally require more effort than mowing short, well-maintained grass.
3. Terrain
- Uneven or Sloped Terrain: Mowing on uneven or sloped terrain will always be harder than mowing on flat ground.
Troubleshooting and Solutions
Now that you understand the common reasons behind a hard-to-push lawn mower, let’s dive into troubleshooting and solutions:
1. Check the Engine
- Fuel: Start by checking the fuel. If it’s old or smells bad, drain it and refill with fresh gasoline.

FAQs
Why is my lawn mower hard to push?
The most common reason for a lawnmower being hard to push is a lack of lubrication. The moving parts, such as wheels, bearings, and blades, require proper lubrication to function smoothly. If these components are dry or poorly lubricated, they can create friction, making the lawnmower harder to push. Additionally, a dull blade can also cause the mower to push harder as it struggles to cut through the grass.
It’s also crucial to check the height of the mower deck. If the deck is too low, it can increase resistance when mowing, especially in thicker grass. Lastly, ensure the wheels are properly inflated and not stuck or jammed.
What can I do to fix a lawnmower that’s hard to push?
First, check for any obvious obstructions in the wheels or blades. Then, inspect the wheels and ensure they’re properly inflated and turning freely.
