A really nice tutorial!!! I was looking for a video with a clear explanation of how does this AWD transmission work. I couldn`t understand how a variety of speed can be reached. No automatic gearbox like for cars. The engine is working on nearly constant speed. The question was how it works by pressing a handle bar only... I was shocked with this. It seems to me, the lever/handle bar provides different friction in between belts and pulleys... just by apply different tension. Wow... that looks like a kid`s toys. At least belts must be regularly changed in this case. Can you tell me whether all the AWD movers work like that or there is more smart and proper speed managing system in the world, please ? :)

My John Deere self propelled mower, after it heats up and shut off, it will not start until it completely cools down??? Have any thoughts?

No néed to take the belt drive cover off, nor the backend of the mower

I have an AWD Husky. Worst mower I've ever had. I've fixed the drive system probably 4x by various means, including fabricating parts. I keep praying for it to die completely, but alas it has a Honda engine. Maybe I will feed it some nitromethane.

for being a high quality brand it sure is poorly designed
