The actuator is from Warner Electric. Could not find thier part #. It is 12" O.C. from pin to pin, closed. Extension is 4". Not sure of the lift capacity, it lifts the tiller no sweat. Not sure what the tiller weights but it is one extremely heavy SOB!!! I have Liquid in both front wheels, and two suite case weights up front and with the tiller lifted the unit can still be a little floaty up front.
One thing to take note of, and to think about if you are building your own ... take a look at the mounting location of the stock CC actuator and the aftermarket one. The CC bracket puts the top pin of the actuator quite a bit higher. This in turn puts the entire actuator in a more verticle plain and lifts closer to straight up.
If anyone wants to drive to west Michigan ... come on over and have a look.
Stay tuned for the Hiller/Tator digger I'm fabbing up out of scrounged parts .... should be too cool. /forums/images/graemlins/grin.gif
Hope this helps,
