My Electric Lawnmower is having issues with the height adjustment

Quick Answer

If your electric lawnmower height adjustment is not working correctly, it is usually caused by dirt or debris restricting the lever or a stiff adjustment mechanism. In most cases, cleaning and light lubrication will restore normal operation.

Tip: The cutting height is typically adjusted using a lever that controls the position of the axle or deck.

Before You Start

Before carrying out any checks or adjustments:

• Switch the lawnmower off
• Disconnect it from the mains power supply
• Ensure all moving parts have stopped completely
• Place the mower on a stable surface

Important: Never attempt to adjust or inspect the mechanism while the mower is connected to power.

Possible Causes and Basic Checks

1. Debris build-up

Check the height adjustment lever and surrounding mechanism for:

• Grass clippings
• Dirt
• Dust or compacted debris

Build-up in this area can restrict movement and prevent the lever from operating smoothly.

Carefully clean the area to restore normal function.

2. Stiff adjustment lever

If the lever feels stiff or difficult to move:

• Apply a suitable lubricant such as WD-40
• Move the lever back and forth to distribute the lubricant evenly

This should help restore smooth movement.

How to Adjust the Cutting Height

Follow these steps to adjust the cutting height correctly:

1. Release the lever

Pull the cutting height adjustment lever outwards.

2. Select height

Move the lever forwards or backwards to choose the desired cutting height.

3. Lock into position

Return the lever to its locked position and ensure it is securely engaged.

Important: Do not use the mower unless the lever is fully locked.

Cutting Height Information

Most electric lawnmowers offer cutting heights typically ranging from:

• 25mm to 75mm
• Positions 1 to 7 (depending on model)

Always refer to your model specification for exact settings.

If the Issue Persists

If the height adjustment still does not function correctly after cleaning and lubrication:

• Stop using the mower
• Contact our Technical Support Team
• Provide your model number and details of the issue

There may be an issue with the internal linkage between the adjustment lever, rear axle, and connecting rod.

Important Information

• Always keep the adjustment mechanism clean and free from debris
• Do not force the lever if it becomes stuck
• Apply lubricant only if the mechanism is stiff
• Ensure the lever is fully locked before use
