Top Bid SN Guide app for iPhone and iPad

Validate the year of manufacture to ensure a reliable value. Avoid paying too much for used construction equipment or not asking enough when selling your current equipment. An error of just one model year (2005 vs. 2006, for example) can change the price by thousands of dollars.
The Serial Number Guide is the leading source for year-of-manufacture data on all major and hard-to-find construction equipment. This means you get over 50 years of serial number information from more than 585 manufacturers representing over 100 equipment types in construction, forestry, paving, material handling and aggregate industries – FAST!
