Yes it is and also easier to dispense when you have an air operated gun and hose real.
And when the economy was good I had the perfect set up on the job for that. We worked out of a 20ft sea crate that was on oil field skids. We had a 1000 gallon fuel tank next to it. In the box we had a generator, air compressor, air greaser, all our layout/staking and gps equipment, rigging, shovels rakes etc, and all the hand tools we needed to get us in trouble if something broke.
Most of our iron was older, -5 komatsu excavators, cat H series and N series bigger tractors, newer M/N series finish tractors, G series graders, 815 and 815B packers, and terex ts14bs, or cat 627E models. For the most part, despite the high hour fleet, we had few break downs and were always productive. Generally at the end of the day the dirt moving iron would break off and head to the box. One scraper would go for the fuel tank, the other would go for grease. Those guys would switch out. Usually one guy would take off for the smooth drum to seal the site, while the other helped the rest in line for fuel. The 815 would then jump in, followed by push cats, finally the finish dozer/grader would finish out the rounds. As you got done, you helped out. Dig tracks, take care of any little items that we could do, then general bs.
