Our CME 550 ATV can go virtually anywhere. With large balloon tires,it doesn’t matter if the job isn’t in a parking lot, we can get there. Although, if the job is on pavement, the rubber tires won’t damage it. The CME 550 is smaller than the Acker Soil Max but still has adequate power to do most jobs. We have upgraded many things on the 550 including the gas engine which was replaced with a more powerful and reliable Cummins turbo diesel. The 550 can turn up to 6 1/4″ H.S.A. and core rock using a large Moyno 3L8 pump. We have achieved depths of 150′ using H.S.A. with the ability to go even deeper.
