Tatiana:”Мой отзыв о мотокосе Shtil FS38 полностью положительный. Родители купили для скашивания лишней растительности. Я не ожидала, что от этой косилки может быть столько пользы. Заводится легко, косит вообще без проблем. Правда, трава летит во все стороны, поэтому косить лучше резиновым жуком. Косилка заправляется смесью бензина 1л + масло 20 мл. Полного бака хватает на 6 соток. А главное, стоит она дешевле газонокосилки и такая же эффективная. “” width=”421″ height=”710″ />

owner reviews

Tatiana: “My review of the Shtil FS38 power tiller is completely positive. My parents bought it for mowing unnecessary vegetation. I didn’t expect that this mower can be so useful. It starts up easily and mows without any problems. But the grass flies in all directions, that’s why it’s better to mow with a rubber bug. My mower is filled up with petrol (1 L) + oil (20 ml). A full tank is enough for 6 acres. And most importantly, it costs less than a lawnmower and is just as effective. “

Sergey: “The impetus to buy the mower was the overgrown ditches of the neighbor’s property. The engine starts after the first pumping. In the beginning the vibration was noticeable, but by the end of the season it was gone. It is possible to put grass up to 40 cm, if it is higher, there will be difficulties with spilling on the mower. Have been operating for 2 seasons now, no significant mishaps so far, except for the spoon, which became a “pain” to refuel. “
