12 foot field gate, how to stop it drooping?

[robinbanks]

A rigid bar is also an option.

Yeah except that bar is going in the wrong direction

if your gate is the same as the posted picture I dare say it'll cease sagging if you cut it in half and have two gate posts..

Do the braces attach securely (bolted through) every horizontal bar?

Depends on the design. In simplistic terms gates are structurally designed in one of 2 ways and then infilled to act as a barrier

It might be that the gate is OK and the gate post is leaning a bit more as time passes.

Photos of the actual gate are needed.

Assuming it’s on a hard standing , not much use over gravel or mud.

Other wheeled versions are available that are more suited to those surfaces...

Amazon.co.uk : heavy duty gate wheel

Thanks to you all for the help and advice, that's given me something to chew on.

To answer a couple of questions:

a) The post has in fact just been replaced, the old one had rotted just below ground level and the guy who installed it did a lousy job and didn't use nearly enough concrete. the replacement post is much better and a friend of mine has done a great job and used plenty of concrete (we even left it for a week to cure before re-hanging the gate).

b) I'd thought of putting a wheel under the gate but the ground slopes a bit in the direction that the gate opens so I guess that wouldn't be suitable?

The spring loaded version accomodates slopes and allows it to cope with a rise of surface.
