Alliance Bobcat Service or A.B.S. is good at what they do. Bobcat services include: Grading, Landscape Prep, Dirt Removal, Concrete Removal, Cleanup and other services. I used Chris(A.B.S.) once and he did a good job. He charged me $ 70/hr at 4 hours minimum, but he took off $ 40 since he was close to where I was. He does not bank hours so if your job is less than 4 hours he’ll still charge the $ 280. The job he did for me took him 2 hours. I could’ve used Chris for another hour but it was getting dark and I didn’t want think my neighbors would appreciate the noise at the time. The bobcat is a track-style drive system. It creates a lot of noise and vibrates the ground very much! The tracks also leave black marks all over where the bobcat turns. I cannot get rid of the black marks all over my driveway. Chris was driving on concrete and I noticed after he left I had a lot more cracks in my concrete than before. The machine is very heavy and broke the concrete where he was going from concrete to dirt. My driveway has a lot more cracks in it than before. I think track-style is good for off pavement surfaces but tires would’ve been easier on the concrete due to the vibrations. Overall A.B.S. did a good job but I would not use them again unless the job did not require him to drive on any concrete surface.
