T-Mech 4-Stroke Gas-Powered Post Driver

The T-Mech 4-Stroke Gas-Powered Post Driver is a heavy-duty petrol-operated tool designed to drive posts, fence posts, signs and stakes with efficiency. It features a high-impact hammer action and rapid post-driving performance, making quick work of tedious manual hammering.

Powered by a 37.7cc single-cylinder, air-cooled four-stroke petrol engine, this post driver delivers reliable power for demanding jobs. Maximum power is 900W (1.2HP) at 6,500 rpm, with torque up to 1.3 ft-lb at 5,500 rpm. The unit provides an impact frequency of 700–1,350 rpm and impact energy up to 41 ft-lbs. Fuel is 86 octane unleaded petrol or higher, and the engine uses a manual hand-pull start.

Designed for user comfort and control, the tool includes side handles for secure operation and a relatively compact, portable form. It weighs approximately 21.9 kg and ships with a durable carry case with wheels for easy transport and storage. The post driver also features a hand-arm vibration rating of 13 m/s², highlighting the importance of using appropriate protective equipment during operation.
