I thought I was good at backing a trailer (video)

That is some sort of strange trailer hitch.

I a real glad there is no video of me trying to back up with the little 8 ft trailer I borrowed.

probably helps that his front end is loaded first, then he makes the turn and loads the rear...
So when that trailer goes down, he has the weight to keep from being dragged along with it.

Nothing special with the trailer, but he is experienced, creative, and pretty good.

looked like a Pintle hitch on a 4wheel trailer....

Independent brakes on rear trailer?

I help a family with hay on their farm, and their wagons work in a similar manner. It definitely helps in small places!

I can jackknife a trailer with the best of them. Maybe not on purpose like that tho!

We Had wagon& drags from France come into our yard with that layout trailer and I had a go at just backing one up in a straight line onto a dock and that was hard enough,

(My job was yard shunter at the time)



although TBF I only had to do normal articulated trailers

Probably..... most (USA) trucks have a trolley valve mounted on the steering column that will actuate the trailer brakes independently.

My wife could back a fifth wheel trailer around the block with no trouble at all.

Guy across the street saw her backing up this log splitter we rented that was mounted on a little trailer up our fairly steep driveway and into the garage next to my 914. He came across the steet and told it her how impressed he was, and she had to ask him what he was talking about.

I think I've backed a trailer up about 3 times now. It's not neuroscience, but it's also far from easy. When I see folks that can do it second nature, I'm always impressed. I had a buddy that could drive/park a boat in ways that I thought were amazing.

Just a matter of where you grow up. Out here I've been pulling trailers with a tractor since I was 12. I can do alright with the car trailer behind the pickup

If I remenber this correctly....The 2-stage airbrake systems operate as such:

1). Supply push/pull valve air to release brakes. Red octagonal valve on the dash.
This ensures brakes lock up automatically when the tractor supply pressure is under 60 pounds(for safety!) Heavy springs inside operate the brakes automatically until they are retracted. Better to be stuck on the side of an empty highway than plowing through a line of cars.

2). Control foot brake-pedal valve operates/modulates normal brake operation at 110(?) pounds. Yellow square valve to supply.

Tip:
1). When backing a trailer(beginning in a straight line), turn the bottom of the steering wheel in the direction of the goal.
2). Only let the angle get so far, then reverse/straighten the steering wheel to keep the curve constant. An angle can get quickly out of control.
3). Slow down when in doubt. Or pull forward and start again.

That was an amazing feat! Backing a trailer with a non-steerable axle is a piece of cake, but the front steerable axle makes it a whole different ball game. I grew up on a farm backing wagons like this (I don't know why it's called a wagon when it's behind a farm tractor and a trailer when it's behind a truck) and it takes a lot of practice.
