John Deere LX173 Riding Mower Parts
The John Deere LX173 riding mower, likely produced in the mid-1990s, was a popular choice for homeowners. These mowers typically featured a Kohler engine and were known for their reliability and ease of use. They were often equipped with a 38-inch or 42-inch mowing deck, making them ideal for medium-sized lawns.
The John Deere LX173 was part of the LX series, introduced as a step up from the lower-end models in John Deere's residential lawn tractor lineup. The LX173 typically featured a Kohler Command single-cylinder engine, often rated around 15 horsepower with a displacement around 426cc. Power was delivered to the wheels via a hydrostatic transmission, providing smooth and variable speed control. Available deck widths included a 38-inch and 42-inch option, providing users a choice based on their yard size. Key features of the LX173 included electric blade engagement (PTO), making starting and stopping the mower deck simple, and a comfortable operator seat. It was primarily intended for residential use on lawns ranging from smaller suburban plots to larger properties around an acre in size. What distinguishes it from other models in the lineup was it's slightly larger engine compared to models such as the LX172, and overall improved features for homeowners seeking a dependable riding mower.
