Industry Leading Performance

The Chapman FM PRO features industry-leading Fuel Injected 23hp Honda Fuel Injected iGX700 V-Twin Engines, which offer unparalleled power and performance in their class for the best results.

The FM PRO models are fitted with forged hammer flails as standard, proven to cope with the most demanding growth, with a cleaner, more reliable cut.

When reliability meets intelligence

The Honda iGX700 offers excellent fuel efficiency due to the electronic control system which continually monitors and adjusts the engine’s air to fuel ratio according to operating conditions and engine load while maintaining optimal performance.

This results in excellent fuel efficiency and low emissions – so good, that in product trials the fuel efficiency was typically 10-12% better than the previous model.

Lower fuel consumption & better efficiency

The FM PRO is paired alongside with Honda’s legendary quality and reliability, the upgraded engines minimise starting issues in a range of conditions and are less susceptible to poor quality fuel, making them even more efficient.

This means lower fuel consumption, less maintenance costs and less downtime – important factors when choosing which machine is right for you making it perfect for commercial and heavy duty users.

Hand Built in the UK

Heavy duty construction and strong attention to detail is the number one priority –  designed for a long lasting life and unrivalled performance against competing machines.

The FM PRO range are fitted as standard with a centrifugal clutch, allowing for safe & efficient operation from the towing machine.

The centrifugal clutch gives automatic drive engagement and disengagement, and combined with the automatic tensioning assembly reduces maintenance by compensating for belt wear and belt loading.
