Hey everyone. Looking for some help here. My trolls seem to more often not work than work. When I power the machine up and go test, I can hear the 'buzz' of them trying to engage, but they don't raise. When I go inside the cab and jostle them around a bit then go back to test they will then raise and lower. Thoughts? It is almost like they may not be getting enough power? Was also thinking an alignment issue, but given both are not functioning right, I doubt that. Thanks for any insight.
