Simpleton question. Why do some timber haulage companies favour wag and drags over artic and trailer?
I have no idea 
They’re off road vehicles. But I’ll take a punt
Grip, capacity and perhaps stability
I imagine it would be to carry two different lengths of timber,maybe 24ft.on wagon and 30ft.on drag which wouldn’t fit on a trailer?Just a guess.never done it.
Or accessability. As we use up the easy to access timber we may be having to go round tighter corners to get to it. A wagon and drag is a beaut for that because you go in truck only, collect a load, trans-ship to the trailer and go back for more. That needs a HIAB though, I don’t fancy handballing that sort of load.
The wagon n drag grips far better in any conditions ,will get in places artic can’t get forwards or backwards, but needs a field to turn round In.
Wag and drag doesnt need too much room to do a 360 turn

Like this fella?
Snap!
I can’t see my lorry & trailer getting round there 
Only with an A frame I’d say.
Lower ground pressure than an artic on fragile forest roads. I’ve heard of a forest local to me that stipulated wag and drags only and with TPMS fitted (Tire Pressure Monitoring System, computer controlled system to allow driver to let air out of tyres from cab to reduce ground pressure). Not seen a UK timber operator use A-frame as in clips above, only ever seen tri axle drawbars.

This^^^ . Wag and drag hardly leave a mark on forest roads. They can be a pain to turn in some cases but can get into jobs artics haven’t a hope of reaching. There is/was a guy from over N/East England who had an A frame drawbar,we tipped side by side in a small local mill and once empty he turned it in the length of its self beside me whereas I needed the usual 20 odd shunts to get round
Just 20? Must have been a good day! Was just reading this and remembered that job that I got sent to round the back of Newton Stewart. Wagon and drag only. Nearly ended up with me being upside down!

I think the Welsh forests are trialling (or have been) the tyre pressure stuff. Mandatory I think now, in Wales. Accessibility is an interesting point - I’ve heard some people say artics can get into places W+D can’t, and vice versa. But traction benefiting W+D makes sense.
The military used to love the a frame turntable trailers, and I suppose manoeuvrability is why! Must take a lot of practice to learn to reverse with two pivot points though!
I used to drive an A frame wagon and drag for Alstons of Ipswich and yes the can be a ■■■■■ to reverse but little movements of the steering is the way to go.

Can’t remember now. It was a white topline cabbed scania

Lol… I wondered if someone would link to those videos, as I was going to as well. Skillful driving
