Since it took off, the rat rod trend has been under more scrutiny than most custom car scenes, especially in Canada, where road laws can be a little harsher than they are Stateside. In fact, the potential illegality of a full-size rat rod is what drove one Ontario man to build this radical rat-rodded 1960s Viking mini-mower instead. Every dark cloud has a silver lining, right?
Even the dark clouds emitted by the 10-hp Yanmar L100 single-cylinder clone driving this thing. Chris “Doc” Smith of YouTube channel Sprocket’s Garage told HOT ROD he built the “Diesel Weasel” using the Viking’s stock hood and frame but with a wheelbarrow tub for a body; a custom front dropped axle; a front bumper made from trailer leaf springs; a one-inch go-cart drive axle; Yamaha brake parts; and the aforementioned diesel one-lung engine.
Best of all, this “mow-kart” – with a top speed of 80 km/h (50 mph) – has a separate tank to feed raw fuel into the exhaust, making this wild weed-whacker a flame-throwing fire hazard, too. (Probably not a feature you want to use on large swaths of grass.)
