FAQ

This is the secondary deck drive belt. Many John Deere 48-inch decks utilize a two-belt system, and this specific belt is responsible for the secondary drive function.
This belt is designed for 48-inch decks on a wide range of John Deere models, including the 180, 240, 245, 260, 265, 285, 320, 325, 335, 345, 335D, GT225, GT235, GT235E, GT242, GT245, GT262, GT275, GX255, GX325, GX335, GX345, GX355, LX172, LX173, LX176, LX178, LX186, LX188, LX255, LX277, LX288, X300, X304, X320, X324, X360, X500, X520, X540, X590, S2048, S2348, 1948, 2148HV, and Sabre models 1842GV, 1948GV, 1948HV, and 2148HV.
This belt measures 5/8 inch in width and has an effective length of 111.4 inches. It replaces OEM part numbers M154958 and M110313. It also cross-references with several industry numbers, including 008-700, 12077, 175-295, 230-5099, 504-00322, 7-078323, 75-295, and B1JD86.
You should inspect your belt if you notice uneven cutting, excessive vibration, or a burning rubber smell during operation. Visible signs of failure include fraying, cracking along the inner V-groove, glazing (a shiny, smooth appearance on the sides), or if the belt has stretched to the point where the tensioner can no longer keep it tight, resulting in slippage.
Before installing the new belt, verify that all deck pulleys spin freely and are free of debris or rust. Check the tensioner spring and pivot arm for smooth movement. If the pulleys are seized or the tensioner is weak, the new belt will wear out prematurely. It is also a good time to ensure your deck is properly leveled.
