The Diesel Weasel Mow-Cart Rat Rod Lawn Mower

The Diesel Weasel Mow-Cart

Canadian road laws inspire Ontario man to build flame-throwing “mow-kart” instead of full-size rat rod…

The whole Rat Rod trend has been under more scrutiny than most custom car scenes, especially in Canada, where road laws can be a little stricter than here in the states.

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.

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 50 mph – has a separate tank to feed raw fuel into the exhaust, making this wild weed-whacker a flame-throwing fire hazard, too.
