Quick Answer
If your cordless lawnmower motor speed changes during use, this is completely normal. The mower uses an automatic variable speed system that adjusts power based on grass conditions to optimise cutting performance and battery life.
Important: No manual speed control is required for normal operation.
Overview
Your cordless lawnmower is designed with intelligent motor control. This system automatically adjusts power output depending on the load on the blade.
It helps to:
- Improve cutting performance in different grass conditions
- Extend battery runtime
- Reduce unnecessary power use in lighter cutting conditions
Normal Motor Speed Behaviour
During use, you may notice the following:
1. Motor speeds up
- Occurs in thick, long, or damp grass
- The mower increases power automatically
- This helps maintain cutting efficiency
2. Motor slows down
- Occurs in light, short, or previously cut grass
- The mower reduces power to conserve battery
- This improves overall runtime
3. Automatic adjustment
- Speed changes happen in real time
- No buttons or settings are required
- Operation is fully automatic
Important Information
- Variable speed is a normal function of the mower
- It is not a fault or performance issue
- The system balances cutting power and battery efficiency
- No user adjustment is needed
Important: The mower is designed to adapt automatically to grass conditions.
Frequently Asked Questions
Is changing motor speed a fault?
No. It is part of the mower’s normal operation system.
Can I turn off variable speed?
No. The system is automatic and cannot be manually disabled.
Why does it sound different in thick grass?
The motor increases power automatically, which changes the sound level.
Does this affect battery life?
Yes, but in a positive way. It helps optimise runtime based on cutting conditions.
