That would be an 18hp Briggs opposed. Are you wanting to find out what kind of angle you can operate one on? Like when climbing a hill?

Yes, it is a 18HP with  plain bearing crankshaft.
I would like to know if using engine in inclination of 15 or 20% would be without risk for the lubricated organs ?

Hmm, yeah I don't know about that for extended periods of time for just a basic splash lube system. I would think it would increase wear with regular use.

I have heard that some voluntarily increase the max oil level to ensure lubrication but this does generate over lubrication of
compression rings and cylinders. Is this really a good idea?

WOW, prolong use like that, definitely not a good idea on a regular mower with a splash lube. As the engine is sitting with both cylinders pointing to the sides, one cylinder would fill with oil from the tilting while running. The rings are not designed to run submerged with oil (goes for any engine). Oil would bypass the rings and enter the cylinder while running and would smoke at first and then stall or hydro-lock the cylinder. Even aircraft radial engines have a way to drain the oil out of the bottom cylinders while running and before every start, spin the propeller to make sure they are not hydro-locked.

Maybe, and this is just a guess, have the cylinders pointing forward and backward, instead of out to the sides. Find out where the splash lube wheel is inside the motor and only drive with the splash lube wheel is on the down side when driving or submerged in oil. In theory would work but you will have limitations on how you will be driving the mower.

ok, in this case it is better for my engine that I favor the inclination of the motor in the direction of the slope like this ?
Inclination ? Hm722_12
In my case, I must favor the presence of oil to the splash lube (Left-Down quarter on picture) ?
Inclination ? Carter10
In conclusion, I have to work my engine in the downward direction of the slope ?

The splash lube wheel being in the front half section of the sump, which would be the front of the engine. Good to know this and Yes, only drive down the hills or inclines. Going up would look like it would starve the engine of oil but you need to get back up the hill to go back down. Maybe a quick run up the hill and then a slow decent when cutting, if that is what you are using this mower for. I think you are getting the right idea now. Maybe do some mods to that webbing in the sump so the oil can flow from one chamber of the sump to the other chamber of the sump. Maybe drill some holes in the webs, if the pic is of your engine part.

Having had serious problems with the old worn tires of my tractor, I decided to order new ones that I mounted with aluminum valves, I took the opportunity to clean the rusted rims

Nice cleaning of the rims. I just took apart some tires that had that Slime sealant inside the tires to keep them from going flat. Keep in mind that the stuff you put in the tires to keep the tires sealed is water based. The rims will rust up inside again if used. I'll never use that stuff again after finding this out.

Your slope idea seems like a good plan to follow. If the engine starts smoking while cutting, just increase the angle going down while cutting a bit. I would imagine that the left cylinder would be getting oil gathered up in the cylinder if it starts smoking out the exhaust and increasing the angle bit would clear out the oil in that cylinder while cutting.
