Tricky gate install

Iḿ back again with another video my last gate the main gate for the property. I can almost start building the actual house can´t wait!.

The gate:

• 4.5meters wide so i can easily drive with a tractor through or other big machines.
• It will be automatic when i have electricity on the property.
• Metal tubing is all 80x40x2mm with adjustable hinges with an M20 bolt. Capacity per hinge is 200kg, you need this overcapacity in a child tries to climb or jump on it.
• Post is 100x100x4mm, 1/3th needs to go in to the concrete.
• Cost less then 250$ pure for metal, hinges and paint
