Construction of a diesel mini hauler

The engine is from a lawnmower. The scythe was used by scythers. Silly names from other languages are not necessary for us. A diesel-powered trolley is fine. Turning the front axle is not too cumbersome? Do you have a workshop equipped like the one in the video? What is the capacity of the loading box? What is the load capacity of the frame? Was something calculated or was everything done by feel?

Has the Yato tool trolley lost its wheels yet?
Will you take a photo with the axle reversed?

The design is cool and practical. However, I have a question from a different angle. What model of shoes do you have?

The name "self-propelled storage tray" fits.

Cool, although with that kind of talent and capability I'd give an electric drive.
Although... here the advantage is that you don't have to worry about keeping an eye on the power supply though, maybe this is a better option after all. It depends where and when it will be used most often.

Scythes were used by reapers - to cut grain at harvest time, or grass during haying. Kosynierzy is the story of how scythes were re-positioned 'for the stiff' for lack of a better weapon to fight with.

There are petrol mowers and petrol scythes. The mowers ride on wheels, while the scythes are taken in hand, often suspended by braces, and swung in the same way as an old steel scythe - wide sweeps from right to left and back "idling". The smallest models, those without harnesses, for trimming around various small obstacles, are called trimmers.

No, the rules of vocabulary are clear the ending ark you add to the stem if you are forming the name of a machine. You have milling machine, drill, dryer, sharpener, loader, trimmer. The rest of the oddities are inventions of people who don't know these rules and gleefully or thoughtlessly calibrate the names.
Scythes weren't re-sharpened, they were re-shifted. After combat action, they could continue to be used by mowers to cut grass or grain.

You've probably never seen a real scythe - it can't be done as you say.



Per Wikipedia :

Typical treatments resulting in the adaptation of a utility scythe to function as a fighting weapon:

forging the blade of the economy scythe by a 90-degree angle (upright) - so that the ribs form a single line with the long spar on which they are mounted;
strengthening the handle that attaches the ribs to the spar (e.g. additional bushing, additional rivets);
reinforcement of the spar of the scythe, especially in the area of the attachment of the ribs to the spar (in order to protect it from cuts by incisive weapons);

Do you take me for a dimwit? I didn't see a scythe put on a stiletto. No one chased the neighbours in the village, the boneheads died out long ago. I have seen a scythe, my grandfather showed me how to mow the grass with it. As you can see, it's hard to equip a piece of sheet metal on a stick with a combustion engine.

Oh lord, it smokes like a two-stroke. And when changing direction I can see the exhaust going straight into my face.

I always thought a battery-powered mower was a no-go - after all, smaller petrol mowers stuck in taller grass. However, I have found that the power of the higher voltage electric mowers (36 volts) can cope even with a drive, although they cut a narrower strip. I thought an impact hammer was only for electricity. The assemblers when they were hanging PCs had a hammer on a battery and with an integrated hoover. These days it really pays to build battery-powered things. This hauler would also be much more convenient if it ran on electricity. Exhaust fumes aside - just changing direction is extremely easy.

If the author is a good mechanic, he doesn't have to be a good electronics or electrician. He could make a very nice trolley powered by an internal combustion engine and OK. As for propulsion - power is always what matters. The more power, the more the trolley will carry in less time.
A combustion engine will give you full power until the fuel runs out. An electric motor will lose power as the resistance of the battery bank powering it increases.

What capacity does it have? What if there is a need to push the trolley by hand? The worm gear does not get in the way?

with a worm gear ratio of 60:1.

Then there is the gear ratio on the chain at an eye-watering 4:1 i.e. a total of about 240:1, and with this ratio a small electric motor would work well (the main problem is 2T motor noise and exhaust). The tapered roller bearings are unlikely to be secured with a seger? The frame gives the impression of being solid, but the plating is thin (a full load of stone would be unlikely to hold it).

If the gear is going to be usable, I would change the muffler for more soundproofing and this taper roller bearing protection.

For continuous use, an electric motor is not justifiable from a practical point of view. For occasional use even more so.

I use DC motors and they meet my requirements.
The ones I have are quiet, which is critically important to me.

This is not a priority for everyone. I use electric ones too, but they are not better for everything.

Let's not kid ourselves, YT-built equipment is mainly about views, while performance is secondary. An electric drive would be boring and less spectacular (clickable) than an internal combustion engine. It's not very modern, the operator should have a platform so that he doesn't have to walk behind the machine, and this engine could probably still pull a trailer with such a gear ratio.

The peasant built himself a cart out of rubbish. I don't understand what the whining is about.

Nice trolley, aesthetically made.

One will pick up on our comments that we are picking on another will see what is worth improving/changing when building something similar.

That is, he won't build a combustion engine anymore because there will be too many views on YT. It must have a platform because then it is practical.
Practical it won't be at all then. After all, it's not supposed to be for driving, but for transporting. A platform generates extra size, because it requires a handlebar, so it has to be big. It is also impossible to stand on it when riding off-road, because the first bump in the road will make this impossible. The platform will not allow you to drive it on the road or even on the pavement (registration, homologation, approval, generator, lighting, etc.), because then it will gain the rank of a vehicle.

A colleague has understood in his own way and is defending his own beliefs by force. I suggested a platform because I know such would get more views. Instead of discussing design flaws, such as the aforementioned seger on the tapered roller bearing, we will be arguing about whether the vehicle was built to earn impressions or utility needs.
Another error was suggested by another user, which could be a problem if the engine fails.

But I am not at all saying that potential problems or oversights in the design should not be pointed out. On the contrary - they are worth discussing.
I can't find that bearing without the protection - where do you see it?

I didn't know about this seger at the bearing and have now found out.
I will select a different type of bearing - thank you for the information.

The electric motor has a disadvantage - or even two disadvantages - the first one is the need for batteries, and here either some gel batteries which are heavy or lithium-ion batteries which unfortunately require electronics And now if you drive it into a puddle, the electronics will probably die, In addition, from vibration and sand it can also die, those expensive cells discharged by leakage current of soggy bms or chargers will probably after a season of non-use have zero volts and will go to waste. The second disadvantage is, as I mentioned earlier, the motor itself and some kind of speed controller is also something that doesn't like water, unfortunately, as the example of many scooters and similar inventions shows, even manufacturers don't quite manage to master waterproofing.

And then there is power, 1 kW is a small combustion engine, but at 12 volts it is almost 100 amps of current and at higher voltages there is a greater risk of something breaking due to water, but 5 kW is an average combustion engine and almost unrealistic electric project for an amateur.

You had a lot of welding, but the trolley came out great.

And then there are the batteries . None of these work in winter in the same way as they do in an electric car

direction of travel is done by turning the front axle 180 degrees.

Super mechanism - especially when you can see in the video how you figured it out. Don't listen to the malcontents - they just envy your ingenuity.

On another note - what was the need behind the construction of this "hauler" ?

[edit]
You finished this "dumper" very carefully, as if you were going to drive it to the FSO exhibition, and yet it is probably a working tool.
