Excuse me for missing the price quote earlier. Your expanded dialog was helpful though.
Have you used the hydraulic thumb enough to to see whether the preferred operation method is locking the thumb in position and moving the bucket toward it or having both the thumb and bucket move together.
You say "either the bucket OR the thumb moves by itself...". Why is this an "either" situation? Is it just the dead weight of either at a particular boom angle that makes one movement override the other? Is the override predictable? IE can you tell which one is going to move first, as in choosing where to position the boom when setting up to grab something?
