A mathematical model of the mechanism for digging large-sized seedlings or removing stumps on the undergrowth is developed, which is based on the idea of the root system and surrounding soil, as a combination of plurality of spherical elements, interacting with each other, and the knife mechanism, as a set of elementary surfaces that interact with elements of the stump and soil. The effect of blade vibration on the stump removal efficiency with the help of the model is studied.

The paper provides description of an approach to calculate main parameters of energy-power block of geokhod computing the hydraulic motor capacity of each end user. The paper determines the effect of geokhod dimensions on capacity consumption by main geokhod systems. The shares of capacity consumed in each geokhod system are calculated.

The article describes one possibility of choosing layout schemes for geokhod systems which is the analytic hierarchy process. There is the essence of the method summarized therein. The usage of the method is considered for the analysis and the choice of layout schemes for a geokhod pumping station. Keywords: geokhod, analytic hierarchy process, pumping station, layout scheme.

Findings concerning wear process of steering gear joints of the truck vehicles are provided. Characteristics of probability of no-failure operation as a function of wear rate of steering joints and pivot connections are determined.

This article considers main systems of a prototype model of geokhod as well as their technical specifications. There are ways distinguished of decreasing the dimensions and the mass of elements of the hydraulic drive. As an optimization tool of structural and parametric parameters of the prototype model of geokhod, there is SimHydraulic simulation considered.
