SAM tractor with front linkage

A very nice project, now to finish what I recommend a 2mm galvanized sheet and paint, it will be beautiful.

My fenders and housing are almost finished
I am wondering about the colors of the round because I have a choice of paints (black, red, yellow, gray, green). I bet on yellow, the fenders green and the frame black.
The tur was supposed to be used for another tractor, but I didn't mount it due to the poor frame.

Well, what is the capacity? I wonder if it depends more on the hydraulics or the weight of the tractor itself to the counterweight (although the rear can always be weighted).
As for the colors, it is suggested to do JCB, i.e. all yellow with a black spoon and trim, and a white inscription with a black border TMK; P

Buddy BC109B, what's the difference in naming a round, loader or lift? What is the significance of the material from which the lift is made, since it is a toy for big boys and the loads to be lifted are the weight of a full wheelbarrow, i.e. 100 kg max. A profile for such a structure, i.e. 40x60x3, is quite enough, in the rounds for Ursus, I would give a wider profile wall and a bit larger dimensions. Looking at similar constructions, I think that the material is appropriate.
Pump capacity 50l, pump during assembly, so I am not able to say what weights will lift. Even if he only lifts 50 kg, I will be happy anyway. Anyway, it's good that you ask because at the construction stage, I can change the design based on errors
Buddy a_noob, the capacity will come out in the wash and as for the counterweight, I plan to give at least 100 kg to the back, if not more
I know about hydraulics as much as, but I wonder why there is a thread on the underside in the manifold. Is it a place for a safety valve, filter or a second overflow?
Please do not ask why so many nipples, reductions and valves are needed. Everything will be fired and now, I do not have typical reductions and this creation is only used to test the lift.

As if someone asked why the spoon was not made of full sheet metal.
I do what I have :-)

A very nice design. How do you drive a hydraulic pump? A belt from a pulley or some other patent from a flywheel or gearbox? And one more question: what did you use this front leaf spring for? All very ingenious!

If the weather permits, on Saturday I will work with the pump drive by adding a second tank to the generator, or possibly to the flywheel. It will come out in the wash, the question is whether the toddler's engine will cope because I do not want to add a new engine to drive the hydraulic pump? The drive from the box comes off because it does not want to weld the differential.

Does your colleague know that TUR is the name of a loader manufactured by Hydramet? I am omitting the name of a non-existent animal species. What does this loader have to do with Hydramet products?

Tur is also a common name for such devices on the farm.
But a city mate has the right not to know.
For example, sneakers, boots, or relaxation should be closer

I don't want to foretell badly, but the V-belt drive may be a poor solution - too much power to transfer. Maybe some chain drive solution from a pulley?

I'll take this into account, but check the bar first. I have a water tank in the pump, I will also add some extra money to the generator, and if the time and weather allow tomorrow, I will inform you about the effects. And I must admit that I have already seen the pump assembled with the Fiat engine, but the tanks were equal on the pump and the alternator, which equaled the engine speed. I test with rotation and, unfortunately, the belt will not work, I will apply your advice :-)

Colleagues, what is the bottom "tit" in the divider and two blind ends for?

If I am not mistaken, there may be outputs for serial strapping (because it does not connect in parallel, because the oil will go where it will be easier)

If the belt pump drive is not from the alternator but from the main shaft, then one belt drives the alternator, the other pump. To lift 100 kg, a car power pump and appropriate actuators are enough [tested practically]

I had a moment for tests. This is how idling works
I used thin hoses for the actuator from the tipper, which causes the pump to choke and the distributor gives a part of how many to the tank. If I find time, I will exchange them
As for the lifting force, I admit that the intended goal has been achieved. 100 kg raises without adding gas and I do not even feel the power drop on the pump.
I will post new videos when I put everything together because in the field and during operation, the truth will come out whether the hydraulics are appropriate.
Referring to the power supply to the pump, I had the shaft on the pulley ready, but during assembly it broke and I had to quickly add the container to the generator. I suspect that the bearing will not twist for a long time. Ultimately, the pump will be powered from the pulley, but at the moment I do not know when.

Contrary to appearances, there are still a few evenings to complete the project, min. Wiring modifications, lights, oil and fuel tanks because these makeshift washers are not suitable and the correct hydraulic oil because I tested the old one. Lol
