My hydraulics keep going sometimes when using a attachment sometimes it will keep hammering real hard in reverse with my preperator or breaker and sometimes they wont even work at all i have to keep shutting the machine off and restarting it. The dealer is so busy i hate for the machine to be down that long i think its in the electronics in the handle. If anyone has any suggestions on what it might be i could use the help. Its a 2005 s 185 Bobcat
