Operate a riding mower up or down slopes , never across the face of slopes . 10DEGREES 15 DEGREES On a riding mower to determine if a slope is safe to mow : ( 1 ) disengage the blade ( s ) , ( 2 ) put the unit in reverse , and ( 3 ) try to back straight up thee slope + if you can back up the slope it is generally safe to mow . However , if you do not feel safe , or if you are not completely sure , use this guid anddo not mow a siop . ethat is greater than 15 degrees , if the riding mower is used with a pull - behind or rear mounted attachment , do not operate the umt on a slope that is greater than t0 degrees . A 15 degree slope is a hill that increases in height at approximately 2.5 feet in 10 feet . A 10 degree slope is a hill that increases in height at approximately 1 + 7feet in 10 feet . Use extreme care at all times , and avoid sudden turns or maneuvers . Follow other instructions in this manual for safety in mowing on slopes .

Torque values are derived at 3060 RPM ; horsepower values are derived at 3600 RPM . Actual gross engine power will be lowerand is affected by , among other things , ambient operating conditions and engine - to - engine variability . Given both the wide array of products on which engines are placedand the variety of environmental issues applicableto operating the equipment , the gas enginewill not develop the rated gross power when used in a given piece of power equipment ( actual " on - site " or net horsepower ) . This difference is due to a variety of factors including , but not limited to , accessories ( air cleaner , exhaust , charging , cooling , carburetor , fuel pump , etc . ) , application limitations , ambient operating conditions ( temperature , humidity , altitude ) , and engine - to - engine variability . Dueto manufacturing and capacity limitations , Briggs & Stratton may substitute an engine of higher rated power for this Seriesengine . 8 _ U _ . DB .
