We just bought a 2013 550 quad this spring and it has about 700hrs on it. We pulled a field cultivator with it this spring and notice no issues. Now this fall we have pulled a 30ft chisel plow with it and a 9 shank ripper and now that its under a decent load when pulling it seems to have a bad drivetrain vibration. Has anyone heard of this and what the issue is or the fix may be? It's not fun to run anymore. Thanks.
