A well-maintained Husqvarna lawn mower is a powerful tool that can make maintaining your lawn a breeze. But what happens when your mower starts moving too fast or too slow? Frustration! This article will guide you through the process of adjusting the speed on your Husqvarna lawn mower, covering the different types of mowers, common speed control mechanisms, and troubleshooting tips. Whether you’re dealing with a self-propelled model that’s suddenly moving too quickly or a manual mower that’s feeling sluggish, we’ll help you get your mower running smoothly and efficiently again.
Overview
Adjusting the speed of your Husqvarna lawn mower involves understanding the specific speed control mechanisms implemented in your model. Generally, you’ll be dealing with either a variable speed control lever or a fixed-speed setting. This article will explore both types, providing clear instructions and troubleshooting advice for each.
Understanding the Speed Control Mechanisms
Before diving into the adjustment process, let’s understand the different speed control systems common in Husqvarna lawn mowers.
Variable Speed Control: The Lever Approach
Many Husqvarna lawn mowers, especially self-propelled models, utilize a variable speed control lever. This lever is typically found on the handle of the mower and allows you to adjust the speed seamlessly while you’re mowing.
Here’s how a variable speed control lever works:
- The Lever: The lever is connected to a cable that controls the engine’s throttle.
- Adjusting Speed: By pushing the lever forward, you increase the throttle opening, allowing more fuel into the engine and increasing speed. Conversely, pulling the lever back reduces the throttle opening, lowering the engine speed and decreasing the mower’s speed.
Common issues with variable speed control:
- Cable Snag: The cable might get snagged or kinked, restricting its movement and affecting speed control.
- Loose Connections: The cable attachment points at the lever or engine throttle might become loose, resulting in inconsistent speed response.
- Broken Cable: In extreme cases, the cable might break completely, rendering the speed control mechanism unusable.
Fixed Speed Control: Preset for Efficiency
Some Husqvarna lawn mowers, particularly manual models, operate at a fixed speed. This means the mower’s speed is predetermined and cannot be adjusted. While this approach offers simplicity, it might not suit all terrains and mowing styles.
Here’s how fixed speed control works:
- Engine RPM: The engine’s speed is set at a predetermined level by the manufacturer.
- No Adjustment: There’s no user-adjustable lever or mechanism to change the speed.
Common issues with fixed speed control:
- Engine Problems: A faulty engine might cause the mower to run slower than intended.
- Wheel Friction: Excessive friction in the wheels due to dirt buildup or worn bearings can impact the overall speed.
Adjusting the Speed on a Variable Speed Control Mower
Now that we understand the mechanisms, let’s tackle adjusting the speed on a Husqvarna lawn mower with variable speed control.
Step-by-Step Guide
Step 1: Identify the Speed Control Lever
Locate the speed control lever on the handle of your mower. It usually has markings indicating the direction for increasing or decreasing speed.
Step 2: Check the Cable for Snags and Kinks
Carefully inspect the cable connected to the lever. Look for any snags, kinks, or areas where the cable is bent or twisted. If you find any, gently try to straighten them out.
Step 3: Tighten Loose Connections
Examine the cable attachment points at the lever and the engine throttle. If they appear loose, use a wrench or screwdriver to tighten them securely.
Step 4: Test the Speed Control
Start your mower and slowly move the speed control lever forward and backward. Listen for any unusual noises or resistance. If the speed control responds smoothly and without hesitation, you’ve successfully adjusted the speed.
Step 5: Adjust for Optimal Performance
Adjust the speed control lever to achieve the desired mowing speed. Remember, a faster speed might be helpful on large areas but could lead to uneven cutting on uneven terrain.
Adjusting the Speed on a Fixed Speed Control Mower
While you cannot adjust the speed on a fixed speed control mower, you can address issues that might be causing it to run slower than intended.
Troubleshooting Tips
1. Check the Engine:
- Spark Plug: A worn or fouled spark plug can reduce engine power. Inspect the spark plug and replace it if necessary.
- Air Filter: A dirty air filter restricts airflow, affecting engine performance. Clean or replace the air filter.
- Fuel System: A clogged fuel filter or old fuel can also impede engine performance. Clean or replace the fuel filter and use fresh fuel.
- Carburetor Adjustment: If the carburetor is out of adjustment, it can affect the engine’s speed. It’s recommended to consult a qualified mechanic for carburetor adjustment.
2. Address Wheel Friction:
- Wheel Bearings: Worn wheel bearings can cause friction and reduce speed. Inspect and replace them if needed.
- Dirt and Debris: Clean any dirt or debris that might be stuck to the wheels, interfering with smooth movement.
Maintaining Your Mower for Optimal Speed
Regular maintenance plays a crucial role in ensuring your Husqvarna lawn mower runs smoothly and efficiently.
1. Routine Cleaning:
