Bespoke Design

Masson are proud of their expert designers, long-standing OEM status and their continuous innovation to meet the ever-changing needs of their customers and of the industry, ensuring their range is always relevant and growing.  Masson can design and manufacture bespoke gearboxes to meet specific requirements.  If you require a unique gearbox please contact the Proteum team today to discuss your requirements.


Masson gearboxes are very easy to maintain.  One unique feature is that the clutch pack can be changed while the engine is in situ.  This greatly reduces the amount of time and inconvenience associated with general maintenance of the gearbox.  The gearbox can be changed using standard tools.

Masson have a Worldwide Service Network of over 30 dealers.  They hold a large stock of spare parts and have a dedicated In-House Qualified Team supplying technical analysis, spare parts recommendations and workshop manuals.
