Adding hydraulics to dump trailer
Hydraulic hoses can be purchased at most auto part stores, ends-to-fit. They are also avaliable on line at very good prices with NPT Fittings. You would need the fitting adapters for your Quick connects amd cylinder. The replacable hose ends are OK for emergency repairs, but not for long term use.
We add hydraulic dump to 2-ton wagons and always use 4" bore tie-rod cyliners with clevis ends. The cylinders are available about anywhere hydraulics are sold since that is also the most popular log splitter cyclinder. I would bet your wagon is set up for clevis end cyliners.
You can get everything you need at SurplusCenter. We order a lot of parts from them and they have always been great to work with.

Adding hydraulics to dump trailer
Just a clarification on cylinder capacities. The "push" capacity of a cylinder is based on the area of the 'bore', not necessarily the rod size. The "pull" on a double acting cylinder is the area of the 'bore area minus the rod area'. For force is either direction, it's the area described above times the system pressure.
To really get a feel of how much push you need to get the box started into the dump position, you need to multiply the gross weight of the box and contents by the difference in the dump moment arm and the center of gravity of the load. In other words, if the center of gravity of the box is 4 feet from the hinge pin, and the lift cylinder pivot pin is 1 foot from the hinge pin, you need 4 times the lifted weight to move the box. In addtion, and maybe more important is the angle and orientation of the cylinder under the box. If the cylinder is on a 30 degree angle, and the cylinder pin is at the same level as the pivot pin, the vertical lift component of the cylinder is only 40% of the cylinder "push capacity".
These are rough examples, but you can see that to lift 4000lbs from the examples above, you would need (4000 x 4)/.4, = 40,000 lbs. The orientation of the upper cylinder pin to the box pivot pin can change these numbers, but these are the things to look at to determine the size cylinder you need.
We use 4" cylinders at 1500psi for our 2 ton dumps.

That trailer looks exactly like the trailers made by Country Manufacturing out of Frederick, Ohio. NorthernTool has them in there catalogue. The 1 ton dump has a scissors lift system and the 2-ton has a 3traight cylinder lift.
Good little dump trailers. Make for a nice tool for hauling.
We use 2-tons, other than the staight cylinder set-up, pretty darn similar to your 1-ton. We use 4"borex24" cylinders on the 2-tons. Just fit. We have to re-build the dump hinge systems. Take a good look at yours, that seems to be the weak point of the trailers.

Amazing, it's exactly the same as the 1-tons by Country Manufacturing. Wonder if there is a relationship of some kind between the two companies.
The only difference is the color. CM paints their's red. We re-paint them Orange/Black. Call them Pumkin Wagons.
Check out countrymanufacturing.com to see the similarities. They have some pretty good pictures of the scissors lift they use on the 1-ton tandem dump wagons.
Use the heck out of them.....

Ya, your one ton dump set-up is similar to the way CM sets up the 2 ton. They use the scissor lift on the 1-ton because of the shorter box.
They are running some pretty good internet sales right now. Especially of you pick them up instead of paying the shipping.
That's about par. It's always on sale the day after you had to buy one....

I'm sure you noticed by now that you get a decent uplift at the hitch when you dump. Make sure you account for then in your ball hitch. Can't hook up to the 3-pt, have to use the drawbar when dumping.
