Christian Livingstone shares his zero-turn mower re-powering project, going from a 12 HP Single cylinder motor to a 20 HP Twin cylinder overhead valve motor, to compensate for a larger mowing deck installation on his 1995 Dixon, model 3304. The video is somewhat lengthy, at about 78 minutes, so there may only be genuine appeal for the true riding mower enthusiasts. But, there is quite a bit of welding and fabrication demonstrated, including a custom, aluminum, diamond plate gas tank, along with a conversion from a vacuum actuated fuel pump to an electric fuel pump. An exhaust modification is made. Best practices for the bending of aluminum sheet to minimize cracking is shown. Some novice wiring and troubleshooting is done. A pulley ratio is changed, along with increasing the engine's top no-load speed to a seemingly modest 3100 RPMs, giving the mower a faster travel speed without outrunning the ability of the blade speed to give a finished cut. The application and use of pre-emergent herbicide is touched upon, along with some brief mention of incidental topics and views, too. A recap is given with rationales for most of the actions taken. On a couple video segments Christian is assisted by a neighbor/friend, who may be the first person in human history to TIG weld for the first time while having someone else doing the filler metal deposition. Otherwise, Christian humorously frames the project as a “Poor Man’s Jay Leno’s Garage: Dixon Mower Re-Power & Mods”.
