The faded picture of the 1450 was also a gift from the company. I appreciate everyone's thoughts about the blueprints. Maybe Kraig can post a couple pictures of the prototype Hydrostatic Original.
Congratulations, Marlin! I want you to know that reading your posts on this forum a few years back is what gave me the courage to finally open up my 15U last spring and replace the trunion seal (which had leaked since I bought my 782 from my Mom back in 2004. So, here's a long belated thank you for all the information you shared. Good luck in your new job - enjoy the fewer hours and less stress on your body. You've certainly earned it!
By the way, did John Deere source hydrostatic transmissions from Sunstrand for the John Deere 318 lawn & garden tractor? When I was growing up, Sunstrand had a great reputation for their hydraulic power products.
Besides my all-mechanical CC 100 tractor, I also have a JD 318 (bought new) and it still works totally great!
