The Nebraska Irrigation Department wants to determine whether they should purchase a used John Deere mini excavator or a Kubota powered rotary tiller for servicing irrigation ditches in an agricultural area of Nebraska. The initial cost of the excavator is $26,500 with a $9000 salvage value after 10 years. Fixed costs for insurance, license, etc. are expected to be $18,000 per year. The John Deere excavator will require one operator at $15 per hour and maintenance at $1 per hour. In 1 hour, 0.15 mile of ditch can be prepared. Alternatively, the Nebraska Irrigation Department can purchase a Kubota tiller and hire 2 workers at $11 per hour each. The tiller costs $1200 and has a useful life of 5 years with no salvage value. Its operating cost is expected to be $1.20 per hour, and with the Kubota tiller, the two workers can prepare 0.04 mile of ditch in 1 hour. The contractor's MARR is 10% per year. Determine the number of miles of ditch per year the Nebraska Irrigation Department would have to service for the two options to breakeven.
