This is a flat rate manual, or service pricing guide (SPG-1023) and does not give any actual service information. It gives you a time schedule telling how long it should take to complete a job on the John Deere 130, 160, 165, 175, 180, and 185 Lawn Tractors. This manual would be helpful to verify the hours you are being charged for labor, or to figure how many hours to charge for a job you are doing.
