I'm wondern' if I'm having the same issue as you with your 3710. I'm familiar with the float and the bucket operation, but what mine does or does not do is operate smoothly...it's way jerky when you try to drop the bucket. I'm used to my last tractor of having a smooth transition when lowering the bucket. This tractor won't move the bucket down in a smooth motion..it's just plain jerky...
Is yours a constant problem???
Have a cab?? I think the controls are different on the cab models.
I got lazy today (between football and kid's work chili cook off. (Did you know alligator tastes just like.......chicken?)
I will get on lubing/adjusting(playing with??) cables ASAP and post the results.
