I have one that is very quiet. My others all make noise to one degree or another. As the gear teeth wear, they tend to develop a whine. Some tractors will have a loud whine in one gear but not the others. This is usually because the tractor spent many years on some specific job that used one gear (for example cultivating or mowing). Although I wouldn't call the whine "normal", many people do. It certainly is common and generally harmless.

Other noises may sound like a click, grind, screech, growl, or whatever. These noises are cause for concern. They usually indicate problems like bad bearings etc. and should be fixed before the damage gets worse. Having them pop out of gear is another indication that a repair is needed.
