I've never hit my leg on it that I can think of.
I use a short section of rope, with a stopped knot at the end as a tether, too. Its tied to the triangle gusset on the tongue. If I like, I can redirect it through the handle for a horizontal, rather than with a tongue-lifting effect. Its easier to move with one guy on the handle, and one guy on the rope, rather than 4 feet and 4 arms in the same area. Haven't tried it with 2 ropes.
When someone is pushing from the rear, they are generally rotating the tongue down, too. The rope at the bottom at the front/ tongue-end counteracts this.
