Hi everyone,
I recently inherited a 1250 IH cubcadet hydrostatic (75' I think.) it's in ridiculously good shape and obviously well maintained. It sat a my uncles house for 3 years before I was able to pry it away from him. It started right away and purrs like a kitten. The problem- it won't drive. Let me elaborate; it will creep forward a few feet then stop. No reverse. It is 'trying' to move. Checked the hydro fluid; full and pretty clean. I would love to get this gem up and running as it is nearly 15 years older than myself! Is there a tran bypass I'm not seeing? Should I replace hydro filter? It rolled relatively easy when we pushed it a short distance to the trailer. It also rolls when the engine is running. Again it sat for nearly 3 years (or more) Thanks a bunch! |

Your hydro valves sound like they are bad. I would change them or get them fixed. A hydro fluid and filter change would help also. I know that there is a guy that makes them or something like that on here. Hopefully some one else can help you with that hook up.

First, welcome to OCC.........
![]() The first thing I would check, is to see if there is a broken "spirol pin" at the Hydro Transmission Input Shaft to Drive Shaft Coupler. See image. These are known to break. What is typically seen, is the drive shaft spins normally but the input shaft to the hydro unit either spins slowly due to friction or not at all.

Make sure it keeps turning when you try to move it. You have to look at the pump shaft. If the key is sheared, the driveshaft will always turn.

You weren't kidding, that thing looks great.
The filter can be seen from the bottom side, coming from the hydro pump, with the top facing the front of the tractor. Hard to miss, unless it's covered in dirt/oil sludge. It looks just like an automotive oil filter but it's not. It's a hydro specific filter and can be found at places like NAPA. Google your Cub model for the hydro filter number, or someone will be along shortly with the number fresh off the top of their head! ![]() |

That is one nice looking Cub for sure. I would lean toward the spirol pin too, but I am far from an expert.

Your situation will most likely be, the Spirol Pin failure or a plugged Hydro Filter. Either will cause a lack of fluid to travel throughout the Sundstrand Hydraulic Unit.

If its not a broken pin I'd go ahead and change the fluid/filter, seems like when they sit the fluid gels in the filter which causes all sorts of issues.

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.
