Self closing farm gates

I have seen only one design in my days.

It consist off a tall metal pole. The gate is welded to a pipe sleeve that will slide up and down on the metal pole.
It also has 2 cables that are mounted to the top of the pole; wrapped around the pole; and then hook to the top of the gate.
When you open the gate 1 of the cables is shortened because of it wrapping around the pole in the correct direction.
The other cable works in a swing to the opposite direction.
This shorting or wrapping of the cable on the pole makes the gate ride up the pole.
With gravity allowed to work the gate closes releasing the tension or wrapping of the cable.

Does this description make any sense????? ???

So I have only seen a few of these and never really used one myself.

Please give me some pointers of things to look out for; different designs that work better; ect.
Or should I just tell him to get off his fat duff and close the gate himself.

Thanks

• Push and drive over gate

My grandfather would always carry a "kid" with him that would swing on the lifetime gate to close it.

Still got the liftime gate, but the "kid" is now too heavy to swing on it.

Go with the "fat duff" option. :>)
