Motoblock Kentavr MB40-3
Description of the Kentavr MB40-3 motoblock MB 40-3 — the most affordable by price, yet fully functional motoblock with an engine power of 7 hp. It has the same V-belt drive as the MB 40-2, a tiller and a new air filter, only instead of two pneumatic wheels its kit includes one support wheel. This is very convenient in work, especially if there is no need to constantly roll the motoblock over long distances. Also not included is a bracket for the front hitch, but if this turns out to be necessary, you can always additionally purchase and install both the bracket and transport wheels sized 3.50-6 or 4.00-8. The tiller gearbox is aluminum, the handlebar has a lightened post with adjustment only by height, so it is not difficult to manage. A motoblock with a V-belt drive has a number of tangible advantages over similarly powered motoblocks with a direct gear drive. First of all, the belt drive simultaneously serves as a power transmission, a clutch and an element of the safety system. If during operation the tiller suddenly jams with a stone or a stick, the belt drive cushions the impact and prevents damage to the engine and gearbox. In addition, a belt-driven motoblock is significantly lighter in weight and cheaper in price, as well as simpler and more convenient to operate. MB 40-3-4 is the most affordable by price, yet fully functional. It has the same V-belt drive as the MB 40-2-4, only instead of two pneumatic wheels its kit includes one small front support wheel. This is very convenient in work, especially if there is no need to constantly roll the motoblock over long distances.
