Cursing-machines usually have a starter motor to pull the lure. Starter motors have about 2shp - enough power to accelerate a men with 160lbs to a speed of 50mph and more.

We are not shure if you really need so much power, because we pull a lure (fox tail) with a weight of 3-4oz.

Because of this we decided to use a smaller engine, with less power consumption but able to accelerate the lure to the same speed.

Our engine is harmonized with power needed to pull the lure.

To control speed the old-fashioned coursing machines use two different methods. The first method is - switching power on, that means always max. power and to regulate the speed by using a brake. Nobody is driving a car in this way. The second way is switching the machine on, and if the lure gets to fast switching it off and on again and so on. Electronic power control would be possible but to expensive because the starter motors a to strong and need to much power.

We use an electronic power control system, because our engine is not oversized and needs less power. That means we control the speed exactly all the time to maintain the same speed the dog is running or to accelerate to a higher speed when the dog is shorten the corner of the course. So no power is wasted.
