How to make a heavy gate self-closing?

[cludelessdiwhye]

We have a large and heavy gate, that opens inwards on our property. We are keen for it to be self closing due to not wanting the dog to escape.  I would estimate the gate would weigh approximately 80+ kgs.

We have added springs to it to make it close, but it is just too heavy (they made no difference).  I am aware of the self closing hinges, but again the gate is too heavy for them.

I have thought of having a counter weight (like this https://www.youtube.com/shorts/5UQ2rx0SOPw), but given the gate swings inwards to our property, it would mean that the device would have to be on the streetside (which would not look great).

I was wondering if anyone had any ideas?

Which reminds me...

I need to replace that unroadworthy castor wheel before I get booked by the council.

I had to mount the bracket like that...

Because when the gate is fully open there is only a narrow space between that and the rock border.

I would deconstruct your fence @cludelessdiwhye.

Get rid of those pickets.

Reconstruct the gate with two sides hinged - new post on the right. This will be the smaller gate for you and your garbage bin.

Self-closer for that gate.

Open both for a vehicle.
