The Dynapac DR7 Rammer is a great price to performance built unit in the Value category and those that do not use a rammer much or in deep trench/dusty settings. It may not have all the bells and whistles premium rammers offer but this one will get the job done at the right price. With Dynapac and Bomag being owned by the same parent company, this is the twin to the Bomag BVT65…again, “V” for value is how we separate these from their premium models. This model will have the smaller Honda GX100 and only a single air filter.

This model and it’s twin Bomag BVT65 (Value rammer) have been discontinued for the US market, below is the link to the DR7X with larger Honda and dual air filter.
