Notes

John Deere's S100 entry lawn tractors are designed for routine suburban mowing with familiar tractor controls and broad parts availability. A representative new price is based on John Deere's published S100-series list pricing for the base S100 configuration.

The "plastic transmission gear failure" scenario can be a tipping point: if the transaxle is damaged internally, replacement of the full transaxle assembly and related linkages may be required, which can quickly exceed the 40% threshold-especially on an older tractor. Repair is more reasonable when the problem is external (shift linkage, belt, pulley) or when the tractor is relatively new and otherwise in excellent condition.

Replace is more compelling when the tractor has multiple concurrent issues (steering play, deck vibration, corrosion) or if the yard size has grown and you're already considering a larger-duty platform.
