Honda power for substantial domestic lawns

Broad cutting performance with a proven Honda engine.

The SP51H pairs a 51cm powder-coated steel deck with Honda GCVx145 power and rear-wheel self-propulsion. It is intended for larger domestic lawns, slopes and uneven areas where traction, working width and easy height adjustment reduce effort.

Ownership planning

The purchase decision continues beyond the specification sheet.

Check suitability →
01 Property fit

Substantial lawns

The 51cm deck reduces passes across broad areas and is better suited to open lawns than very tight spaces.

02 Terrain

Slopes and rough sections

Rear-wheel drive and larger wheels reduce effort, but safe operating limits in the manual still govern slope use.

03 Servicing

Honda and Mountfield schedules

Follow the engine and mower maintenance requirements and retain servicing evidence where warranty terms require it.

04 Support

Use MF-2L0536133/MC and the serial number when requesting manuals, parts or warranty assistance.
