Sumo deadlifting in comps

hey, was wondering if sumo deadlifting is sometimes not allowed in strongman comps? if so, why and how do they judge it to be one or the other?
need to know as i hope to compete eventually and need to see which one i prefer.
thanks in advance!

It's NEVER allowed in SM comps

Try doing a car or farmers deadlift sumo.

If your hands are inside your feet then it's a sumo deadlift - There is probably a more technical definition somewhere but this should see you right

Dose every comp striclty forbid sumo technique?

As above though, good luck doing some of the odd deadlift variants!

Every comp I've competed in or spectated on, yes mate

Cool. I was wondering whether it was traditional/assumed as much as anything. My wondering is over!

cheers! good to have a definate answer! and i can see the point about deadlifting cars and so on.

do any of you strongman competers do sumo as part of your training anyway?

I know Mick does them on the very odd occassion, but certainly not with any regularity

i once saw a guy at a comp doing a sort of half sumo thing, one arm inside his leg one outside, he done well from what i remember
