IMPORTANT: Claas forage harvesters of the types
498, which are fitted with a variable header
drive, can change the speed within the cutting
length settings. In order to avoid very high
drum speed, you cannot use the 4th gear of
the multi-speed transmission.
NOTE: When the 3rd gear is operated with maximum
variable speed, this corresponds with the 4th gear.
