Operating Instructions34RECOMMENDATIONS FOR MOWINGDANGERDo not mow around overhanging treebranches or bushes at the same height asthe operator’s torso and head where inad-vertent contact may cause injury.Avoid Low Hanging BranchesIMPORTANT: Operate the engine at full throttlewhen mowing, to allow the engine to produce fullhorsepower and to increase efficiency of the enginecooling system.• Keep the mower deck and discharge chute clean.• Mow with sharp blades. A dull blade tears thegrass (resulting in poor lawn appearance) and usesextra power (slowing the mowing speed).• It is preferable to cut grass when it is dry and nottoo tall. Mow frequently and do not cut grass tooshort. (For best appearance, cut off 1/3 or less ofexisting grass height.)• When mowing, operate the engine at or near fullthrottle for the best cutting action and performanceof the grass handling system (GHS). Mowing with alower engine RPM causes the mowing blade to notcut clean and tear the grass. The engine is designedto be operated at full speed.• When mowing in adverse conditions (tall and/orwet grass), mow the grass twice. Raise the mowerto the highest setting - 4 in. (102 mm) - for the firstpass and then make a second pass cutting to thedesired height.• Use a slow setting on the FSC for trimming op-erations.• Make sure the mower is leveled properly for asmooth cut. Refer to Deck Leveling in Assembly Instructions.• Use an alternating stripe mowing pattern forbest appearance and vary the direction of the stripeeach time the grass is mowed to avoid wear patternsin the grass.• Avoid damage to the grass by slipping and skid-ding of the drive tires. Use smooth control move-ments of the steering levers since the hydrostatictransmissions are “power boosted controls” and jerk-ing the levers can easily slip the tires. For sharp turns,do not allow the inside wheel to stop and twist ongrass; pull inside steering lever into reverse for asmooth “rolling” turn (one wheel rolling forward whilethe other rolls backward).
