Aftermarket John Deere D140 Parts

When we help customers source John Deere D140 parts, the same problems come up: intermittent no‑crank after storage, blades that won’t engage, sloppy steering, and deck belt slip under load. The John Deere D140 is a non-road lawn tractor, so dust, heat, vibration, and moisture are constant. Small electrical and linkage parts often fail before major components do.

This category focuses on high-demand repair items such as the 12V 30A 5‑terminal relay GY20437, neutral safety switch GY20157, PTO switch GY20939, and positive battery cable GY21749—the parts that restore reliable starting and engagement. To browse by brand first, use aftermarket John Deere parts and aftermarket John Deere tractor parts.

The John Deere D140 parts here commonly list fitment across D100/D105/D110/D120/D125/D130/D140/D150/D155 and sometimes D160/D170, plus select LA and X series shown per item (examples: LA130/LA155, X140/X165/X166/X167). We also include service items like gasket LG690970 and chassis bushings M123811, where they match these platforms.
