ZDE, LLC has purchased the defunct AMW-CUYUNA Engine Co.

The new company, CUYUNA Engine, LLC, goal is to provide support to engines in the field with the manufacture of spare parts as well as develop new and inovative products. ZDE, LLC has the largest inventory of CUYUNA/2SI engine parts in the world.



Established in 1989 as a lawn and garden dealer, Zerkle Diversified Enterprises, LLC has evolved into a diverse power equipment retailer.

Founded in 1989 by Roger Zerkle, educator, author, and Aircraft Mechanic, ZDE has always had an interest in Sport Aviation. In the early 1990's, ZDE became the exclusive distributor of Cuyuna and 2si engines for the recreational market, supplying OEM's dealers, and end users around the world. When the AMW-Cuyuna engine company suspended the manufacture of recreational engines in 2003, ZDE became the world's largest source of Cuyuna/2si engine parts. 

We also are dealers for LS Tractor, IHI compact excavators, Hustler zero turn mowers, Paddle King Pontoon boats, BOXER mini-skids, Tohatsu outboard motors, Harman Pellet stoves, EGO battery powered equipment, Green Mountain Grills, Red Max, and decorative metal animal art objects.
