Abstract：The cuting device is the core component of the riding-type dual-disk lawn mower，playing a crucial role in the qualityandreliabilityof itsoperation.This paper designs a riding-typedual-disk lawn mower that mets operationalrequirements basedonthe actual needs of modern lawns.Through static simulationanalysis of the mower blades using ANSYS Workbench，the study shows that the maximum stresson the blade is 63.34 MPa，which is much lower than the allwable stressof 35O MPa for 65 Mn，meting the operational requirementsand ensuring operationalsafety.Modalanalysisof the mowerbladesreveals thatthelimitrotational speedcoresponding tothefirst-order natural frequency is 7611.6r/min ，while the maximum working rotational speed of the blade is 3000r/min ， far below the dangerous rotational speed range，thus preventing resonance.Kinematic simulation using ADAMS shows that the maximum contact force whenthe blade contacts the weeds is225ON，whichis much higher than the cutting shear force required，indicating that the cutting components can eficiently complete the mowing task under normal working conditions.The research results providea data foundation and new ideas for the optimized design of the cutting device in the riding-type dual-disk lawn mower.
