I have probably seen new tractors being transported like that hundreds of times but never took a closer look until I walked past this one parked at the hotel we stayed at.

What is the wood blocking around the hit h plate for? Do those have that much range of motion that needs to be isolated?

Looks like the forward wood beam has the front tandem axle chained up.

I assume that they remove the axle shafts from the rear tandem axles and install a cover on the hub.

Most likely it's just the air bags deflated, either by the driver or from the air bleeding down from sitting/not running.

Pulling the axles means you're not having to spin the differentials, prop shafts and transmission gears of the towed trucks. Better mileage and minimal wear on the components of a brand new truck.


ETA: I'm guessing the small 2"x4"s on the axle are safeties for the jaws clamped to the front axle, the other blocking is to keep the 5th wheel plate from tilting. You see those rigs moving quite often but I never paid that much attention to how they're hooked up.

I've always wondered about those tow setups also.  Can the air brakes be plumbed such that the lead tractor can control braking on each rear axle of the other two?

Those tires have so much tread on them.  Most trucks I see in parking lots are running on really sketchy tires with very little tread, especially trailer tires.

Probably pulled the axles to keep the transmissions from turning. Isn't all the gear oil in the tailshaft at that angle?

You pull the axles so you don't burn up the transmission in the truck that has the engine off... No oil flow in that transmission

Saw that exact same thing as OP this past week except they were moving down the interstate.

That may be "the way it's done" but it still looks sketch as heck.

They lock the plate because there is a pivot point on the bracket under the axle.   You don't want two pivot points or it'll be really sloppy.  Chain the front tandem up so you only have to pull shafts on the rear one.

Yup, a lot of stuff is still spinning in a manual transmission even when it's in neutral unless you drop the prop shaft or (in this case) pull the axles

Pulling the axles is good but-Tow it on the rear wheels an appreciable distance you run the risk of smoking wheel bearings, hubs and axle snouts.
You are better off pulling the driveshafts- many H-D differentials have an oil pump in them to circulate oil to the bearings and axles. If the carrier/pinion isn’t rotating oil is not circulating.
Towing biggins isn’t as simple as “hook it n book it”

I bet that turns great with the 5th wheel locked at that nasty angle.  I don't know why they don't make the front axle clamp / Kingpin at roughly the correct angle so the 5th wheel is sitting level, then allow the 5th wheel pivot to do it's job, instead of forcing a twist into the frame of the towed truck when making a turn.  I suppose the front axle of the towed truck can tilt enough to allow the terrible geometry.

People get away with a lot then wonder why the kingpin is all broken up in their trailer.

ETA: I see the bracket is locked to the 5th wheel so it can't turn and give it that broke in look and there is a second pivot pivot above that allows for turning, but it doesn't appear the angle is improved on that one either.

Wrecker drivers like to tow single truck tractors from the rear (backwards, with just the steer tires on the ground) so they don't have to drop the drive shaft.

I my experience (12 years in the towing business) it’s generally not very practical to do so. Due to size you cant just turn around in the middle of the highway and snag it from the rear. You also have air deflectors and wind dams to consider.
If your doing a power swap it makes no sense (a power swap is when a tractor dies with a load and you tow out a fresh tractor and tow the dead one back)
Locking the front wheels is not like it is on a passenger vehicle where you use a tie rope, seat belts and similar.
One of the biggest factors though is steer axles just aren’t designed to take the amount of weight  towing from the rear puts on them.
Like I said in my earlier post H-D trucks are a different critter to tow.

I saw a car towing 2 other vehicles on the expressway last week , while I was heading to Florida.  Then another car towing package that was the same.  All with drive out tags.  65 south, out 0f Montgomery, surely heading to Texas.  I wouldn’t think that’s to safe, but Alabama State let’em ride, so I guess their all bueno.

That's nothing, it looks professional. If you are on the Interstate often enough, especially in Texas, you'll see a pick up truck towing a pick up truck towing a pick up truck back to old Mexico... Sometimes a suburban.

Those are wrecks sold at auction, all headed to Mexico. They put the best running one in front, the other two POS cars "In Tow" and send it. The drivers have questionable documentation/insurance but generally the police won't mess with them as long as they are still moving down the road.

Yes. On city buses, we had quick-coupler connections for "shop air" to keep them aired up in the shop, and "tow air" to work the brakes while towing.

No. Automated manual transmissions on some, still conventional manual trans on others.

ETA: Actual "automatics", while rare in heavy trucks, are somewhat more common in medium-duty trucks.

OP's pics reminded me of a Kenosha WI businessman who operated at new truck transport company. Among other shady dealings, he "persuaded" the DOT to allow an increase in the number of trucks in tow, thereby significantly increasing his revenue per trip. I met a retired truck driver in Kenosha who worked for the company, and he confirmed what I had read in the newspapers years earlier.
