I am going to have to deal with dads collection soon and I don't know where to start. He has 3 or 4 dozen old deeres from a spoker D through most of the two cylinders and then into the1010/1020/2010/2020/3010/3020/4010/4020 standards in gas and propane with a few diesels thrown in. Some are very rare, some are not except have consecutive serial numbers so they caught his eye.
He thinks I should sell them off over a few years but I don't even know how to start most of them let alone what to ask. Plus I dont want to be dealing with this for a decade.
Any suggestions of where to find the value?
