Need to swap buckets on a 55-NX with quick attach. The bucket release lever moves a spring loaded pin that holds the bucket in place. I can pull the release lever out about 1/3rd of the way. It won't budge any more. In the past I've used a cheater bar on loader quick-disconnect levers, but this release handle is too large to fit anything around it. I've tried putting the bucket on a stump and gently nudging it forwards & back, nothing frees up the release lever. Any suggestions for breaking this free?
