Instead of a "whole raft", list the JD loaders you want specs on someone may post them. Give us a chance to help.
The manual for my 640 lists them, I also have old brochures with many models and their specs.
Well I guess I am looking for the 300 series. Not sure how many models there are but I would like to compare them to the Kubota loaders that go on their 30-40hp tractors.
