I have never been a real fan of the new dirt scoop's dump mechanism. I rounded the corners on my dump handle latch and added a 1' extension with a piece of square tubing to give me the leverage I need to dump the bucket. I used to have to set the bucket on the ground to release tension against the latch before pulling my dump rope, but my modifications made the mechanism a lot easier to operate.
In the 1950's I grew up using a dirt scoop that had a much better designed dump mechanism (see attachment). I believe that it was a Dearborn scoop, and it's dump lever was attached to the bucket instead of the frame. My drawings are crude representations of the mechanisms. The old style scoop dump arm had a spring behind it (shown in red) and a lip that extended out under the fixed roller to latch the bucket in place. When you pulled the rope, the lift arm released and also became a handle to assist in rotating the bucket full of dirt.
I have moved thousands of loads with the old scoop and the new scoop and I prefer the old Dearborn style.
