Engine for the "Neva" walk-behind tractor: characteristics, features of selection and operation

One of the most important types of machinery in agriculture is the walk-behind tractor. Its main plus is multitasking. The special love of consumers both in the domestic market and abroad was won by the Russian Neva walk-behind tractor produced by the Krasny Oktyabr plant.

• weight - 99 kg;
• maximum speed - 13 km / h;
• track 3 cm;
• ground clearance 14 cm;
• turning radius - from 110 cm;
• angle of lateral statistical stability - 15 degrees.

This is the basic package. But today there are other variations, which are indicated by additional numbers after the main name, for example, "Neva MB-2K-75" or "Neva MB-2H-5.5". Basically, they differ in their "filling", which affects their capabilities. During use, you can replace equipment parts and increase its performance. In addition, any part of the mechanism has its own expiration date and when something is worn out, it will need to be replaced. There is nothing wrong with that, and even a good engine will sooner or later fall into disrepair. In this case, you can contact a specialist or deal with the issue yourself.
