TRANSMISSIONS OVERVIEW

The Valmet 702S features an 8-speed synchromesh transmission, complemented by a 16-speed two-speed powershift, providing versatile and efficient gear selection for varying terrain and load conditions. This dual transmission system enhances operational efficiency and improves torque management, allowing for smoother power delivery, particularly in demanding agricultural applications. However, operators must be familiar with the complexity of managing multiple gear ranges, which can pose a learning curve.

TRANSMISSION 1

The Valmet 702S tractor features a synchromesh transmission with 8 forward and 2 reverse gears, facilitating smooth gear shifting and enhanced control during varied field conditions. Its 310mm dry disc clutch provides reliable engagement but may require more frequent maintenance compared to hydraulic options. Ideal for tasks demanding versatility, the dual range transmission is beneficial for both low-torque applications like tilling and high-speed transport.

Type synchromesh
Gears 8 forward and 2 reverse
Clutch 310mm dry disc
Description Four gears (1-4) plus reverse (R) in two ranges (low/high).

TRANSMISSION 2

The Valmet 702S features a two-speed power shift transmission, offering 16 forward and 4 reverse gears, which allows for a versatile range of speed and torque management suitable for varying agricultural tasks. This design enhances overall operational efficiency and minimizes power loss during gear shifts. However, users may face a learning curve with the transition between gears, particularly in complex field conditions or when precision work is required.
