How much did you pay for your quick attach system to use your forks that you are no longer going to use because you want to clamp forks to your bucket??
I think you already know the answer is it will take you longer to clamp the forks on by hand than just dropping the bucket and picking up the forks.
Have you ever considered, or is it possible, to put small actuators on the quick detach levers? Like linear actuators or small hydraulic cylinders.
On my PowerTrac it came with a quick attach system that operates hydraulically. I just set the bucket down, pull a valve near my knee and back away from the bucket. Drive over to my forks, pick them up, push the lever and lock it in. It litterally takes me less than 15 seconds to change implements without getting off the tractor.
I'm surprised no one has gone after the niche market of quick attach automation conversion kits. Are there kits out there?
