Saw this in my Northern Tool magazine anybody have any experience with or heard of this seems too cheap but figured I'd ask. Plate dimensions 21 1/2"x16 1/2" /compaction force 3527lbs: 5600 BPM. Engine is a Robin ex-17(this is my main concern my current stone has the honda 5.5 and it has been trouble free for 3 years). price is $899.00. This would be my backup tamper for a second crew that I currently have enough people for but not a second tamper. Wouldn't get used everyday, but is something I could use.
