Abstract：Inordertoaddresstheisseofpoortraficabilityandthesubstantial sizeof pickingand handling machinery inhilly orchard plantingareas，asmallcrawleragricultural chasis with goodadaptabilitytothe working environment was designed. The stabilityanalysis ofagriculturalchasis ramp driving and the ANSYS finiteelement simulationofchasis frame were carried out. The findings indicated that the power chasss was capable of operating on slopes of 30∘ ，fulfilling the requirements forramp driving stabity.It was foundthatthe maximum displacementoftheframeunderfulload conditions was 0.55mm ，and the maximum stress was measured at 95.44MPa . The structural design was confirmed to meet the strengthand stifness requirements.The first six natural frequencies of theframe fell within therange of 28.63Hz to 118.65Hz ，which did not coincide with the excitation frequency applied by the engine to the tracked chasis frame，nor with thevibration frequencyaplied bythegroundtothewalkingmachinery.Consequentlyresonancecould beavoided.Inthe normal operating stateof thechasis，itwas ensured thatthe frame would notsufferdamage due toresonance.The chassis was recognizedforitsstrongclimbingability，goodstability，anditscapabilitytooperate freely inorchardenvironments with 1.2m betweenrows，thusadequately meeting therequirements for fruit handling after picking innorthern hilly orchards.
