Relief Valve Differences????
I need some teaching about what the difference is on a 1250 and 1450 hydro relief valve?
My 1250 hydro valves have manual relief which typically is used by pulling the bar on the right side of the console. It’s been broke off for years so manually pushing the button allowed us to push the tractor freely I’ve recently purchased and upgrading my hydro pump with a 1450 ported pump so I can add the hydro lift. The 1450 relief valves no longer have the manual button on them. How do these values work without the button on the top ? Are they self reliving when the system is not charged? Trying to learn more about these

During the Quietline series IH made a switch from Manual Relief Valves to Automatic Relief Valves. Tractors with S/N <597244 had manuals and S/N 597245> had automatics.

Unless you can find NOS, the Manual Type of Valves are NLA from Cub Cadet.

FWIW:
Do remember unlike the manual valves, automatic valves will allow the tractor to roll on an incline when the engine is not running. You don't want it running off in the bushes and leak liquids, or worse

I have NO clue why someone would want these Manual operated valves verses the Automatic ones.

Well I see 2 reasons possibly, why a person would prefer the 1st design.
One would be it keeps the tractor stopped or almost stopped on an incline with the engine off. Sort of a safety for someone not familiar with the equipment. The other would be if one was a purist, and wanting everything down to the last nut, washer and bolt to be as it left the factory, like is done on say one seeking a perfect "100" at a Corvette restorers gathering. Possibly other reasons I've not thought of.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
