I volunteer as a ranger and occasionally drive a MF 5455. I would love some advice about the correct use of the speed shift function. I know it changes the transmission gearing but the manual says it should only be used for short periods when the tractor needs more draft. But as I don’t do any cultivation work (only use the tractor with a tree grab and for flail moving) I am not sure what that means. Others who use the tractor just keep it oermantly in the higher gear speed shift option, so ‘faster’ on the road. But is that correct / OK?
