70 yo female here Great video. Clear picture and sound Clear step by step instructions.Finally a guy that knows what he's talking about!! Thank you.

Thanks for a great instructional ,clearly spoken video. this is the 1st time I have worked on a drive like this and the original belt was gone so your vid was priceless. Only different way I did it was with mower deck on and hoisting the machine to a 30 degree angle to have better access.

Thank you for the video! Also important to note: The pulleys are flat or V-shaped and the belt has a flat side and V-shaped side. I just realized now that john deere delivered my mower with the belt flipped so the V-shaped was on the flat pulleys and the flat part of the belt was on the V-shaped pulleys! The belt worked for 5 years like this but started to shred. The new one I installed thanks to your video is on the correct way.

nice see the run of the belt, but no need take the deck out

Unfortunately My X350 deck is different.. This vid did not have the same pulley arrangement for my yellow 48" deck.

How about a video for the 42"? Thanks!

I need to replace worn John Deere u-bend Pin M173440. How do you remove and install them?

The hardest part in removing the mower deck on my X350 is removing the J-pins. You make it look so easy with those brand new mowers, but this is always a hassle for me. I lower the deck all the way as in the video, but then it's a struggle getting those pins to release all the way. I have all sorts of scrapes and bruises on my hands fighting with those pins. Any suggestions? Thanks.

What size belt is the bottom one

What size belt is this? I got the M169500 which seems to be the belt online but it doesn’t work.
