A comment
I bought a cultivator more than 7 years ago. All this time he has been working properly, and there are no special complaints to him. American 4-stroke engine for 6 horses. There is enough power to plow virgin lands (the land is not heavy - sandy), there are no problems at all when plowing already plowed areas.
The weight is very small, only 45 kilos, its compact dimensions allow it to be transported in the trunk of a nine, I do not dare to leave such a handsome man in the barn at the dacha. For cultivation I use 4 rotary mills. The only caveat is that the cultivator is very sensitive to stones and weeds. Periodically, it is necessary to unwind the weeds from the cutters, and make sure that the stones do not get stuck between the knives, otherwise they will bend.
Pour 92 gasoline, the same as in the car. The quantities are just ridiculous, after the winter, before starting the seasonal work I clean the carburetor. For all the time 3 times changed the spark plugs.
pros
reliable, unpretentious, powerful
Minuses
a very sharp start with habit can and miss
