Small Engines (Lawn Mowers, etc.): Riding lawnmower engine speed, question pool, ground speed

Question
How fast should I run my 13 1/2 HP Craftsman 42" cut riding lawnmower engine when mowing?

My neighbor says to run it on max. high speed?

Thank you,
Richard Slusser

Answer
Hello Richard:

Sorry for the Delay. This Question was in the Question Pool. When Cutting Grass, Run the Engine at Full Throttle and Regulate the Ground Speed with the Transaxle. Hope this Helps. I am Here if You Require More Assistance. Let Me Know What Happens, Please. Thanks.

Good Luck
