I'm getting ready to put a new wire harness in the 782 so I switched the 44c deck over to the 982D for mowing duty. It went much faster than I thought. I just had to change the positioning of the undercarrige and lift links and check the side/side and front/back level. That diesel just sips the fuel while mowing. I also ordered new heim joints/rod ends for the steering from mcmaster to replace those worn out junk oem parts.

Isn't that the truth. I'll be hard-pressed to use up one tank full by Fall.

Had a few limbs to haul. We had a bad storm last night with some hail. My wife snapped some pics.

Got my hydraulic/ power steering pump mounted and tried it out. I hooked up a gauge and flow control so I could check the pressure output of the pump. It got up to 1200 PSI before the belt rolled over on the pulleys and trashed the belt. It was a junk China belt from TSC. Gonna try to find a good belt next time. I think 1200 PSI is a little too much so I'm gonna try to shim the relief valve in the pump to lower the pressure a little. I'm thinking 7-800 PSI should be more than enough.

Does anyone know what kind of pressure the hydraulics normally put out on a Cub?

I still need to find a valve and some cylinders but I think I know a guy who might have some I can use. I'll check with him next week.

Sorry guys, no pics yet. I dropped my camera a couple weeks ago and killed it.

You would need to remove shims to reduce the pressure. I think my manual says that 782s are set at 600-700 psi, and the larger 982 at 7-800 psi. I wouldn't go a lot higher than 800, either.

Thanks Matt.
I found a site that talked about increasing the pressure on a GM pump by removing shims to increase pressure on the relief spring and thereby increasing pressure output so I'm going to add shims and try to get it down around 700-800 PSI.

That must be backwards of the way the hydro pump reliefs work.

Either that or whoever wrote that is wrong...I can't envision how you would make a relief valve in which you would remove shims to increase the pressure. That seems counter-intuitive. If the relief valve is a plug with a spring and cone- or ball-shaped plunger under it, you will need to remove shims and not add them.

Now you've got me really curious as to how the relief valve in it is designed.

Do you have a GM pump or some other brand? I googled around and found that a lot of other PS pumps have a relief valve more like what the hydrostatic pumps use, where you'd remove shims to decrease the pressure.

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.
