Why UK Homeowners Choose the Mountfield SP185 Li Kit

1. The SP185 You Know — Without Petrol

The original Mountfield SP185 is one of the most recognisable mowers in the UK. The Li version keeps:

• The same mowing feel

• The same 46cm deck

• The same reliability

But eliminates:

• Pull starting

• Oil changes

• Fuel storage

• Fumes and noise

Just push the button and mow.

2. 48V Battery Power You Can Trust

The high-capacity 48V 5Ah battery provides ample power for the motor and drive system. It comfortably covers lawns up to 400m², depending on conditions.
Benefits include:

• Quiet operation

• Constant power without bogging down

• Long battery lifespan

• No cables and no emissions

There is also space to store a second battery (optional) to double your mowing time.

3. Professional Cut Quality

With a 46cm steel cutting deck, the SP185 Li Kit:

• Cuts efficiently

• Handles uneven ground well

• Leaves a clean and even finish

The anti-scalp comb helps lift the grass before cutting, giving a more uniform result even on older lawns.

Six easy-adjust cutting heights let you switch quickly between a low summer cut and a longer spring or autumn trim.

4. Strong Grass Collection System

The 60-litre hybrid collector:

• Packs grass efficiently for fewer trips to empty it

• Has a light textile base for airflow

• Includes a full indicator

For longer grass, you can switch to rear discharge to keep moving without clogging.

5. Self-Propelled Convenience

The mower drives itself at a comfortable walking pace. This is especially helpful for:

• Sloping gardens

• Thicker grass

• Longer mowing sessions

It gives the same ease of use homeowners expect from the SP185 petrol version, but with far less noise and vibration.

6. Built to Last

The Mountfield SP185 Li Kit is engineered with durability in mind:

• Steel deck instead of plastic

• Brushless motor with fewer moving parts

• Ball-bearing wheels for smooth rolling

• Robust handle joints for long-term reliability

Registering your mower qualifies you for Mountfield’s long domestic warranty, reinforcing its reputation for reliability.
