Default Hydro pump questions

I have lost a lot of forward speed and little to no reverse power at all. Should I rebuild the hydro pump or could it be a trans issue?

I would suggest you take the time to check and adjust your Hydro Linkages first before tearing into the pump.

Another suggestion would be to change the positions of the Check Valves. Switch from L to R, see if that is an improvement. If it is, then one of the check valves is bad.

My crystal ball that I consult for model and year identification of what you are working on has gotten quite cloudy today after the spring rain storms.
So a general reply would be in order.
If it is something older like most fellows here have, I would suggest a fluid and filter change if it is a 30-40 year old machine.

Now if it is something much newer I have no clue.
On a side note, the older stuff that had the sunstrand hydro's are pretty much bullet proof and you shouldn't need to have someone go inside it.
As most parts are very expensive, and don't generally go bad unless someone drug it down the road with a motor vehicle.

My crystal ball may be cloudy too but I wouldn't know because I left it in my other pants.

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.
