Gravely is acting up. This is my second season using my Gravely 36" gear drive just bought it new at the start of the year. im using a sulky on it to. But my problem is that ever time the right gear seems like it gets stuck i let the lever down to engage it so it starts moving the left one starts going but the right one doesnt kick in. i have to mess around it to get it going like giving it alittle puss to go.
