A 91 Murray is an old machine and a workshop manual is likely to be hard to find.
If you have the old 42" cutting deck V belt you have a better chance of acquiring the correct replacement belt. 1. There maybe a part number on the old belt that will give you a lead to assist the service outlet in ordering a new belt. 2. If the part number is not visible on the old belt, you may have the old belt measured, to determine a replacement belt to order, with consideration to stretching and deterioration of the old belt. 3. If you can identify the cutting deck model/part number you maybe able to identify the V belt to suit.

Contact a local auto parts store, a full service one, bring in the old belt and they can match it.
