A-B-C-D = Four Work Areas; How To Change Speed Range - Valtra T Series Quick Start Manual

A-B-C-D =
FOUR WORK AREAS
Valtra continuously variable transmission (CVT) is truly a working machine.
There are 4 working areas with 2 sweet spots per area, where transmission
efficiency is over 90%. A total of 8 sweet spots is the highest amount in any
CVT tractor in this segment!
+ Best efficiency for all tasks (save fuel and transmission)
+ Optimal transmission efficiency for every task and every driving speed
+ Best pulling ability
+ 92% of speeds with excellent transmission efficiency
It is easy to find the
sweet spot of each
range by calculating
25 % and 75 % of
the area's top speed.
