Efficient combustion technology optimises power delivery throughout operation. More time can be spent achieving outstanding mowing results.

Smooth Self-Propelled Operation

The rear-wheel self-propelled drive eliminates much of the effort required when mowing larger or sloping gardens. Smooth traction helps maintain steady progress across uneven ground and longer grass. Reduced physical effort improves comfort throughout extended mowing sessions. Larger gardens become easier to maintain.

The advanced Dynamic Speed Control (DSC) transmission uses a conical clutch system for gradual, controlled acceleration. Smooth power delivery improves manoeuvrability while reducing sudden movements. Better traction creates greater confidence across changing terrain. Comfortable operation enhances the overall mowing experience.

Flexible Cutting and Collection

The 51 cm cutting deck delivers clean, even mowing while covering more lawn with every pass. Six adjustable cutting heights, ranging from 22 mm to 80 mm, allow easy adaptation throughout the growing season. A convenient single lever makes height adjustment quick and straightforward. Flexible cutting options help maintain healthier-looking grass.

A spacious 60-litre grass collector efficiently gathers clippings for a cleaner finish after mowing. A practical full collector indicator lets you know when emptying is required. The supplied mulching plug finely recuts clippings before returning valuable nutrients to the lawn. Rear discharge provides an additional cutting option when required.

A durable powder-coated finish resists scratches and corrosion throughout years of regular use. Quality construction ensures dependable long-term reliability.
