Hi, being new to the tractor world and Kubota I was wondering how to tell the model year of a Kubota BX1880? Is it depicted in the serial number? Do these tractors depreciate like vehicles do from year to year. So being 2019 year now if a dealer tries to sell you a new tractor that is actually a 2018 for the retail price that is quoted on the Kubota website now in 2019 that will certainly affect the value of the tractor when it is resold correct?
