Have any of you guys tried this type of set up? How well does it turn, is there 6 way lockers as an option. Is there a problem turning out of field drive ways with less weight on the front end?
I would imagine it would be great weight distribution on soft dirt roads.
Also are some units with a pusher axle a better option , so you can raise it up when not needed?
I was thinking of going this way instead of boxing a tri axle truck. I like the way most tri axle trucks are set up with a 18 speed, 600hp and heavy front axles and wide front tires. It seems more difficult now to find highway tractors spec ed out as a heavy duty farm semi.
Also alot of tri axle trucks dont have near as many miles on them although I bet they are used in rough conditions hauling logs.
Thanks ahead for any advice.

I've never run one but I do see the odd guy with one at the elevators and have talked briefly with them. While part of the goal they had was to carry a bit more, it was also a matter of traction to make it up such and such ice covered hill they dealt with constantly or to move in less than ideal field conditions in the spring while filling a drill or in the fall at harvest time. Of course they can only be used in front of a trailer that has a dolly to king pin distance that will work and more tridem trailers these days are set up for that. They do not turn well though, the turning circumference is not good and those three axles want to track ahead and poor steer tire traction is compounded by the characteristics of a tridrive. Also a tridrive when manoeuvring around in a yard with a load, my god do they rip. I get fuel delivered mostly by a tridrive body job and they are a bit of a beast. As to the lockers, I could be wrong but I believe that most of them you will find will have 6 way lockers, the two power dividers for axles 1 and 2, and then all three with the side to side lockers. Never even attempt to turn if the side to side lockers are on and your loaded !. One would need some decent approaches or wide roads for sure to be running that combination. Sure are a lot of tridrives up here in the Peace country for both forestry and the oil patch, fuel delivery and propane trucks etc.

Few guys around here have that combo. They will go anywhere you want as long as it’s straight.

I don’t think pusher axles are recognized in western Canada area they? As far as tridrives go, have a few friends with them, haul a little extra, they are heavy empty, turning just ok.

There are a couple grain trucks around here with tridrives, whenever I see them, I just think cumbersome. Not sure but I still think that the steering axle would be the limiting factor for allowed weights. Our corners on municipal roads would make a tridrive truck and trailer near impossible.

Long wheelbase truck it’s hard to get weight on the steer axle. Tri drive it’s harder to do.
The tri drive straight truck would be like a tandem trying to not overload the steer axle.
