Well i started that land clearing job i posted about 5-6 weeks ago. I rented a deere 450lgp dozer for a week to do some work on that job. I never ran a dozer before. I hoped right up in it when it got dropped off and made a fool of my self on it before i handed the keys over to my foreman. Seems like a dozer is alot harder to operate efficently then a excavator.
