How the ‘Zammoth’ creators fulfilled a lifelong dream

Tusky waves a Mammoth flag atop the Zammoth, a Mammoth-themed Zamboni for fans, after the Mammoth defeated the Edmonton Oilers 6-5 in overtime of an NHL game held at the Delta Center in Salt Lake City on Tuesday, April 7, 2026. | Isaac Hale, Deseret News There’s hardly a vehicle under the sun that David “Heavy D” Sparks and David “Diesel Dave” Kiley haven’t driven. Thanks in large part to their TV show and their significant social media presence , the “Diesel Brothers” been able to experiment with monster trucks, boats, helicopters, semi trucks, heavy machinery, hover crafts and everything in between.

But until recently, one particular vehicle had evaded them. “I think I speak for all men everywhere when (I say) it’s our dream to drive a Zamboni,” Kiley said at a media scrum during the first intermission of the Utah Mammoth’s game against the Edmonton Oilers on Tuesday, where the “Zammoth” made its debut. The Zammoth is essentially a Mammoth-shaped party bus that parades eight fans around the ice surface at the Delta Center at a time.

The Mammoth commissioned the Utah-based Diesel Brothers to design and build it, and they got to take the first lap around the ice, firing the T-shirt cannon and cheering with the fans. The Zammoth in all its glory #TusksUp pic. twitter.
