Between the two videos you should be able to replace the belt.

I would believe the mower is ran off a belt and the belt has stretched to the point and needs replacement. Raise the mower up and look under it and see if the drive belt is sloppy or loose.

comment on what you call a tensional drive belt

What are you working on, and what is a "ground drive belt"? Sounds like something on a lawn mower. This is the car and truck section.

Ljcmy. I would love to help you but what vehicle are you referring to? The more info you give the better answer you can get...I am going to assume you are talking riding mower..so if you are..you can go into the web to Lowes,Home Depot,Sears or any of the bigger store sites..and go to their home and garden or mowers etc..and click on parts then drive belts..just put in the name and model of your mower...they have plenty of different ones. I am sure you can find yours...also if you have a eBay account you can get them much cheaper just do the same put in the name and model and drive belt.....good luck..

You can reuse it. But you need to find out why it was thrown off. Check all the pullies by grabbing them and checking for side to side movement, With the exception of the power steering pump pulley (which has some in and out play) they all should have no play. Just turn in nice smooth circles. Sorry I don't have the diagram, but there should be one under the hood. Sometimes on the bottom of the hood.

timing belt and most drive belts are good for 70,000miles, i think the mechanic trying to take you for a ride, as for the drive belts inspect them if there is any cracking ware marks etc replace them but seriously if they look like new which they should with only that many miles would not need replacing.
