I was in Cortland NY at a Yamaha dealer and noticed this dragline pulling gravel out of the pond. The valley here is mostly gravel that is full of water, dig a hole, and it fills with water.
Start pulling bucket before it hit bottom , track should be facing water to back aeay when needed. I did same job as this one working 11 years digging material from water to pile .
I was impressed with his casting the bucket. I played with a dragline for a few minutes once when the boss had his for digging farm ponds, would have taken me quite a while to get anywhere near that good.
