It’s not on Gehl it has a horn button on the wheel. I’m having trouble with transmission slipping. I thought the button might be some sort of a Clutch cut out switch but there is a Clutch cut out switch on dash. When I put it in gear it works fine for a minute but is soon as I stop and try to accelerate again the machine hardly moves. Any suggestions?Well on a jcb it's the horn button.
It’s full.Check the fluid level too. Low fluid can cause what you described.
