The project site will require clearing and grubbing prior to beginning earthwork operations. to select the appropriate dozer, the following should be considered: - there are both 335-hp and 460-hp dozers available - the site to be cleared is 75’ wide by 3/4 of a mile long. - the site is generally level and poses no traction problems for the equipment. - 60% of the trees are pines, 40% are oak - the total number of trees per acre is about 300; of those: - 140 trees per acre are 1 to 2 ft in diameter - 50 trees per acre are 2 to 3 ft in diameter. - 35 trees per acre are 3 to 4 ft in diameter. - the current plan is to clear and grub in one operation, and then follow with piling-up in windrows and burning. part 1 - identify which dozer, or combination of dozers, provides the best production rate.
