I've had the CCM hydraulic toplink on my L4300 several months now and think it's great. Just started using it with my new Woods 65" Boxblade and noticed a problem.
When I go to extend the toplink while holding the BB off the ground with the 3pt. hitch, I hear a deep vibrating groan that can be felt as well as heard. This doesn't occur if I extend the link while the BB is on the ground or while retracting the link, BB on the ground or not.
I figure the weight of the BB is causing the cylinder to try to overrun the hydraulics and the checkvalve is rapidly opening and closing to prevent this....and that the checkvalve action is the cause of the groan. If I've got this right, there's not much that can be done about it; but I'm wondering if someone else has a better answer. I did a search but didn't find anything...may not have used the right terms.
So, has anyone else experienced this? If so, Are there any solutions other than simply lowering the implement to the ground before extending the link?
Thanks.
Bob
