I am planning on changing the drive belt on my Exmark Lazer HP this weekend. I bought a used 02 model for my personal use and tt has about 500 hours on it. While changing my blades last week I noticed the drive belt has a lot of cracks. Time for a new belt. I have a new belt but I need some instructions on how to change the belt. I didn't get the owners manual with the mower so I'm looking for some help. Thanks in advance for any help you can provide.
