Every Swisher product has a model and serial number on a silver decal. For the majority of our units, the model number will describe the traits of the machine. Large units, such as trail mowers, log splitters, Zero-Turn Riders, etc., start with one or two letters. These are the classification of the unit (e.g., T for "Trailmower", ST for "String Trimmer"). The next set of numbers is usually the engine size (e.g., T14560 has a 14.5 HP engine). Finally, the last numbers generally describe the size of the product (i.e. ZT18542 has a 42" cut, or LS10528 is a 28 ton log splitter).
Serial numbers are VERY important for choosing the right manual as this will identify the year of production. Serial numbers after 1999 began using a system that most of the manuals in this section follow. They'll start with the letter L and then a single number. This just shows which assembly line they were produced on and does not affect the manual. The next two numbers show the year. There will be a dash, and the next three digits are the Julian Day Number of the year the machine was made. The final set of numbers is simply which numbered unit it was on the production line that day. As an example, a serial number showing "L204-123097" would tell us it was produced on Line 2 in 2004, the 123rd day of the year, and was the 97th machine produced that day. Machines from 1997 and 1998 do not include the L# and just display the year. Older serial numbers used a different system, so please contact us at 800-222-8183 for assistance.
