Welcome to the group Kenneth.
The 3021 is a very new model and the factory has released precious little information about it. However, the new models are very similar to the models that preceded the one you own. The entire line of tractors has been based on the patented hydraulic drive system going back to 1962. Over the years, improvements to the frame design and other parts have been made but there has not been anything all that radical. What you read on this site in the Tech Library that pertains to the old Colt tractors, the later Case-branded tractors and then the Ingersoll-branded tractors will mostly apply to your tractor. This site has the most comprehensive library of information about the entire lineage to be found anywhere on the internet.
Whatever questions you have, some of the answers may be found in the FAQ's section. Other questions can be asked in the main forum. If you do not have an Operator's Manual for your tractor, then that would be an excellent place to start. One of our dealers can sell you that manual and send it by mail.
