So that sounds like you are eliminating the hydro, correct?

No- keeping the transaxle and existing tires. Electric motor to drive it.

1. The input to the hydro (i.e. the driveshaft) uses the rubber barrel type flex connector, so where is the tapered, keyed input to the transaxle that you are talking about. 2. If you are going through the hydro, that would control your speed. So why do you need a speed controller for the motor? |

I removed that rubber flex connector. There's a tapered shaft, keyed, with a 3/8"X24 threaded shaft in there.
Correct- no need for motor speed control. |

Myself and others here on this forum have used the 2000/3000 series driveshaft and couplers to modify/improve the drive system on older Cubs with the flex discs.
You might consider retaining the shaft/coupler at the hydro input and fabbing/making a coupler to adapt the driveshaft to your motor output. That would retain for you some degree of flexibility in the driveshaft, plus you could retain the mounting for your cooling fan. BTW, the inside diameter of the of the 2000 is 5/8". |

Good idea, Ironman! Perhaps you can look at the picture attached and tell me where I might find a coupler to match this hydro input to my 1/2" motor shaft?
My driveshaft is shown in the picture also. Appreciate your help! |

Maybe something like this coupler from McMaster-Carr.
You could either cut cut off one end of your driveshaft and insert a piece of 5/8 rod and bore the coupler 1/2" on one side and 5/8" on the other side, or 1/2" and driveshaft o.d. on the other side. https://www.mcmaster.com/shaft-coupl...ft-type~round/ |

Thanks again, Ironman!
Think I have the coupling issue resolved. Would you know of where I can find a complete description of the operation of that transaxle? Trying to identify the controls on it- I know the throttle, and probably the "Neutral" lever, but there's one more lever I don't know what it does. A Brake, maybe? A detailed picture of the hydro would be helpful. John |

Success! After fabricating an adapter to couple 1800 watt motor to hydro, I found it does indeed have enough power to run the machine! However, all the throttle linkages have been scrapped, so I "hard wired" the throttle rod full open (max speed), and am using the electric motor controller to control vehicle speed.
Question is- will this use damage the hydro, since it is made for constant (high) speed input, and using the throttle to control vehicle speed? I've locked the hydro in full speed ahead, and changing the motor speed to control vehicle speed. Will the hydro survive? |

One thing to keep in mind is the the hydro is designed to run in one direction. If you want reverse you need the hydro for that.

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.
