TRANSMISSIONS OVERVIEW

The Valmet 905 features an 8-speed synchromesh transmission, providing smooth gear shifts, and a 16-speed two-speed power shift option that enhances versatility for various field operations. The advantages include improved traction and fuel efficiency during different work scenarios, enabling optimal performance across diverse terrains. However, operators may need time to adapt to the complexity of the two-speed power shift system, which can increase the learning curve for effective utilization.

TRANSMISSION 1

The Valmet 905 tractor features a synchromesh transmission offering smooth gear shifts with 8 forward and 4 reverse gears, enhancing torque management and operational efficiency. The 330mm dry disc clutch provides reliable power transfer while minimizing slippage, which is advantageous for heavy-duty applications. However, the complexity of the synchromesh system may require more maintenance compared to simpler transmission types, impacting long-term operational costs in rugged conditions.

Type synchromesh
Gears 8 forward and 4 reverse
Clutch 330mm dry disc
Description Four synchronized gears (1-4) in two ranges (low/high) plus reverse range.
