A contractor plans to use a wheeled loader to move 5,000 BCY of soil 500 feet using a 50-minute working hour. The soil has a swell of 15%. The loader has a bucket capacity of 2.5 cubic yards. The soil has a fill factor of 1.2 and a weight of 2,500 lbs per LCY. The loader has an STL of 50% of 15,000 lbs. The loader will haul in one direction loaded at 2.5 miles per hour and return at 3.5 miles per hour. The total cost of the tractor is $55.00 per hour. It has a fixed time of .35 minutes. Remember that the loader will be moving the dirt in its loose state. 

What is the productivity of the loader in LCY per hour?
