A contractor plans to use a crawler tractor that is being used to move 5,000 BCY of soil 500 feet horizontally in a 50 minute working hour. The soil has a swell of 15%. The tractor has a straight blade 10 feet long and 4 feet high. The average width of the base of the soil pile in front of the blade has been measured to be about 5 feet. Assume that the tractor travels in first gear forward at 2.2 miles per hour and returns in a second reverse gear at 3.4 miles per hour. The total ownership and operating cost of the tractor is $55.00 per hour. Use a fixed time of .10 minutes. Remember that the tractor will be moving the dirt in its loose state. What is the productivity of the tractor in LCY per hour?
