You've done a great job getting your 1864 up and running! A tractor with "sentimental value" makes it all worth while to restore!
The 1864 is a wonderful machine in the CCC/MTD family of tractors...especially with features such as power steering, hydraulic lift and an excellent Sunstrand hydro transmission. Please check out the pictures of restorations I have done to 2 - 1641's and my favorite, the 1864!
Scroll down and click on "CCC/MTD built tractors", then click on "Let's see your CCC/MTD cubs". From there select "last page" and you will find my pics on page 60 and 61. When you see these pictures, I know that you will be inspired to fully restore (take completely apart and reassemble) a really great machine.
My Cub Cadet restoration ventures all started with the restoration of my Dad's 1641. Then another 1641 and my latest, an 1864. I bought parts from dealers on this site as well as partstree.com, Jackssmallengines.com, ebay, my local Cub Cadet dealer plus parts from friends, tractor shows, and craigslist.com. I had so much fun on my daily searches, hunting for the parts I needed to restore these tractors to the best of my ablilty! And now, I am having so much fun using all my equipment!
If you like restoring mechanical things, Cub Cadets are the way to go. The only cub cadets.com website will give you a wealth of information on everything you need to know to do the best job possible. You will be rewarded by your effort, gain knowledge about these machines and make some nice friends along the way!
Wishing you the best of success with your 1864!
