REDI Driver Boss 78

I was pleased it handled 3 1/2" wood posts in moderately hard soil with cobbles. The vibration dampening is so good I didn't think it was working until I realized I have driven the a post 2" into the ground. It has limits but is an effective portable option when utilized properly.

Good machine cheap parts

Machine works well. Pounds a post 3 feet into the ground in seconds. The throttle assembly is a bit cheap. The stop button doesn't function at all and came loose and fell out of the housing on first use. No reply when contacting customer service.
