You are operating a Cat D$7$H dozer with a straight blade. This dozer

has a maximum ideal production of $200$ lcy$/$hr$.$ You are pushing a dry

non$-$cohesive material weighing $2000l\frac{b}{c}y$ in its loose state, $250$

feet uphill on a $10\%$ grade. The operator is of average skill, slot

dozing, and the work will be done at night. The superintendents

expect a $45$ minute work hour. Using the information above calculate

the productivity LCY$/$hr $($nearest value$).$

the material weight factor is $\frac{2300}{?}$ soil unit weight

TABLE $7\mathrm{.}2$ Caterpillar job condition correction factors for estimating dozer production

"Note: Angling blades and cushion blades are not considered production$-$dozing tools. Depending on job

conditions, the A blade and $C$ blade will average $50-75\%$ of straight$-$blade production.
