My drive belt keeps slipping off. What size do I need to replace. It's Sunday so Lowes and HD were not much help.

Got the serial number off the back of the deck?

Honda did issue a Service Bulletin way back in 2002 for some HRS models where the transmission could pivot too far, allowing the belt to come off. There is a special stopper kit (3 washers) that can be installed that will limit the movement and help keep the belt in place. Not all HRS models will benefit from this kit, so need the serial number to consider it. Some HRS mowers came with no washers, some came with 2, and others may need to use 3:

The affected range is 60000001~6099999.
