KOMATSU is introducing "significant upgrades" to one of its harvester heads – aimed at boosting productivity and user experience

Key improvements on the C124 include a redesigned valve block and enhanced hydraulics for the feeding system. 

According to the manufacturer, feedback from test customers has been overwhelmingly positive, particularly noting the head’s smooth operation and efficient feeding.

The new head is due to launch in 2025. 

Key enhancements
The most notable upgrade is the introduction of a new valve bank, which offers improved durability, reduced wear, and lower energy losses – resulting in fuel savings.

Additionally, the pressure control for the front and rear knives has been refined for greater precision, with adjustments now fully managed via software. 

This allows operators to easily control settings like the knives’ opening pressure from inside the cab. The hydraulics for the tilt functions have also been improved, resulting in smoother operation and potentially higher measurement accuracy during processing.

Advanced Length measuring is the new standard
To ensure high and consistent measurement quality, advanced length measuring is now standard on the C124. This update includes a stronger cylinder and a modified mechanical stop to reduce wear.

New saw unit and feed system
The saw unit has been redesigned with additional clearance between the saw bar and frame to prevent collisions. A reinforced, curved base plate enhances durability while reducing the unit's ground footprint. The updated design also provides more space around the saw motor, making daily maintenance easier and more accessible.

The new feed system features high-flow motors that enhance performance and reduce energy losses. The upgraded system also includes improved hose routing for easier servicing and extended service life. An optional reinforced hose protection layer is now available to further increase hose longevity.

Additional Options and Improvements
The 2025 model introduces the “Find End” option, which automatically resets length measurements without requiring a new cut, reducing waste. The option has been updated with a protected lens and debris-resistant design for longer service life. 

Other enhancements include improved centring for small stems, stronger bushings with better sealing for front delimbing knives, and new feed rollers with spikes for better grip and measuring accuracy in challenging conditions.

A statement added: "These upgrades collectively make the Komatsu C124 more efficient, durable, and user-friendly, offering operators greater control, reduced downtime and improved productivity even in the most challenging environments."
