OK. Does this sound correct? The charge pressure is higher than the lift pressure. On a ported pump w/ports capped the relief valve on top acts as the charge pump relief. when you add an implement lift you change the location of the charge pump valve to the side. ANYONE?

![]() I have been staring at that flow chart. Is that a typo of the implement and charge relief valves labels being swapped?? ![]() Also, the implement relief can not be higher pressure than the charge, can it? All the oil would go to the lowest relief valve in a parallel circuit!!?? Maybe when there is no implement circuit, the charge can be 200psi, when the implement circuit is added the pressures for both have to be increased. I do not know for sure, but, I would think you can not get 600psi out of a 200psi circuit. Kind of like wishing you could get 600psi at the garden hose of your house to wash your Cub Cadet when the rest of the house is 50psi. I'm lost, I think is will go wash my Cub Cadet!! ![]() |

I'm with CADplans
I didn't think the pressure could be like in the chart That's why you need to swap out the valve springs when adding an implement lift, Right?

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.
