Sad thing is the trucks will all arrive at the pile at the same time .... no matter what... the combination of traffic, stop lights and convenient stores...
then the driver that thinks the other direction is better...
we have several hoes... but not always available .. one the only takes 2 scoops to load to the 200 deere which is probably 6-8.. We have to load level with top of bed to keep the DOT hassle to minimum.... a royal pain .... cause if they stop one, then all your truck will be setting on the roadside...
scraper piles are general hard compacted, so one needs to make dirt while the trucks are gone... which is usually only a few minutes... loose dirt loads faster.. even though you spend a few minute between trucks you will load faster with a small hoe...
The smallest hoe I've used to load trucks 312 cat ... we had a 270 deere that went down. about 30 buckets to load tandems.... The foreman wonder where all his trucks where.. I told him he would have heard the radio traffic, if he wasn't garage selling.
