DC motor with speed control????

I am trying to put a DC motor on my lawn fertilizer spreader. Here is my problem. I need to be able to adjust the output of the motor for the “throw” distance. I am thinking about 1/3 HP motor. Does anyone know if I can use an AC light dimmer for this control?, Probably not, that would be too easy. If you have any suggestions please let me know. Thank you

1. Use R/C car parts. Board with reciever and control for the motor.
2. No you can not use an A/C dimmer. You need to go to your local Radio Shack and they will help you get what you need!!!
3. a rheostat is a rheostat and it should work but I don't know for how long because of ohm's law. Simply put it states that your current times your resistance = your voltage---your voltage divided by your resistance = your current--- your voltage divided by your current = your resistance A rheostat is a variable resistance device if your current doesn't get to high you will be okay
4. You can get a DC controller for fractional horse power motors pretty cheap at an industrial electronics store.
