I maintain an orchard for habitat mostly (hobby, not commercial). Both of my tractors cannot hang on to turn signals. I took em off as I got tired of spending the money every year to replace em, only to break em off in August again. My tractors very rarely are on the road, and even then the are open so hand signals work just fine.......
I have now gotten to the point where I just don't put them back on the tractor. no reason to except for looks, and these are working machines, pretty don matter.......
