Heavy-Duty Aluminium Gearbox

This model features a commercial-grade 3-speed gearbox housed in a tough aluminium casing. Internal components are made from hardened steel with solid gearing, ensuring precise control and long-term reliability under heavy use.

Twin Blade Overlap Technology

With its 77cm cutting width and overlapping twin blades, this mower significantly boosts efficiency—offering up to 45% greater productivity compared to standard 53cm machines. The deck design enhances grass collection, mulching, and side discharge performance.

Independent Cutting Height Adjustment

The mower allows separate height adjustment for the front and rear, offering 15 cutting positions between 17mm and 129mm. This flexibility makes it suitable for everything from fine lawns to more natural grass finishes.

Efficient V-Belt Drive System

An optimised V-belt layout ensures smooth power transfer while reducing wear. This design improves durability and helps minimise maintenance downtime.

4-in-1 Mowing Capability

The Virtue 77 TBO offers multiple mowing options:

Rear collection
Rear discharge
Side discharge (ideal for longer grass and rough areas)
Mulching with included baffle and blades
Enhanced Wheel Design

To support its increased size and weight, the mower features larger, wider wheels. This ensures even ground pressure, helping to protect lawn surfaces from damage or marking.

User-Friendly Operation

Designed with operator comfort in mind, the controls include durable rubber grips, integrated safety levers, and easy-access throttle and speed controls. A built-in parking brake provides added safety when stationary or during transport.

Simplified Maintenance

Routine servicing is straightforward, with easy access to key components such as the oil dipstick, spark plug, air filter, and oil system—reducing downtime and keeping the machine running efficiently.

Reinforced Deck & Front Bumper

A sturdy front bumper protects key components from impact and also serves as a convenient lifting handle. The rolled steel deck edge adds extra rigidity, ensuring long-term durability in tough working conditions.
