The model G2XD-4 is the most powerful gas post driver in its class it is powered by a 4 stroke Honda motor producing nearly 2 hp yet only 50cc displacement. Skidril invented gas driven post drivers back in the 1990's and the company is the world leader in post driving machines. A great product at a good price from a name you can trust.
The G2XD-4 is protected by a 3 year engine and 2 year driver part warranty and a limited lifetime warranty.
