Alignment and calibration steps are the final stage to ensure optimal performance and safety. Begin by aligning the deck, pulleys, and belts with precise reference points or marks, ensuring there is proper belt tension using the recommended method, whether through tension gauges or deflection measurements. Calibrate the drive system by checking the alignment of the mower blades or cutting units relative to the spindle housings, and adjust as necessary to minimize vibration and uneven cutting. For steering and hydraulic systems, verify hydrostatic drive alignment and adjust linkage lengths to achieve straight tracking and responsive control. After initial startup, run the unit at low speed on a test surface while listening for unusual noises or vibrations, and confirm that throttle response and engagement levers operate smoothly. If discrepancies are found, perform a careful re-check of alignment and fastener torque, then re-test until the performance meets the established specifications, recording the results for warranty and service records.
