Na most mentem le hídba. Lehet, hogy a zseniális X-TORQ motor ZENOAH ???

Husqvarna, 150BT, Pro/Commercial Grade Backpack Gas Blower, 50CC, 2.1HP, 2-Cycle X-Torq Engine, E-Tech II Emission Control, Maximum Air Speed 180 MPH, ...
Ennek  REDMAX motorja van, ha igaz, amit írnak.

"My understanding Husky 150Bt is Redmax EBZ5100. But when I inquired Husky through email, they claimed it is the same but 150Bt have more power. It is 495cfm and 180mph."

"I know the motors on the backpacks are part for part the same as redmax. We've used husky part numbers to repair redmax blowers...."
