My neighbor who had recent knee replacement asked for my help changing his deck belt on his Z920m.  I watched this video and BAM -- easy as pie.  Thank you very, very much.  (Now I want pie)

I have  Z model 48 inch and i found out the plastic pully covers ( made for looks and safety) were rubbing against the deck belt and eventually shredded it . Rather than trying to cut away sections of the covers , i just took them off . Your microphone is working great by the way . Nice tattoo also 🫡

Thanks for doing this video. You explained everything very well.  I also need to replace my drive belt and blade adjustment spindle and you have video's on both. I glad I found your video's and have already subscribed.

Rather then remove the spring, you should just use a 1/2" ratchet in the pulley that is what that square hole is for. You see it on tensioner belts in cars
