The tractor shakes less, but in the second summer it started to smell the engine until suddenly it blew up (obviously the warranty had expired).
It's not worth its money, maybe it happened to be defective.

Just do yourself a favor and don't buy it. It is completely poorly made. As soon as I assembled it, with great care since its materials are fake, it started shaking, creaking, and making noises like a tractor. I should have never bought it.
