The aim of the work is to scientifically substantiate a way improve technical, economic and agrotechnological performance indicators machine-tractor units, compiled on basis traction power equipment category 1.4, main technological operations in cultivation various crops by reducing level dynamic processes their connections. It established that elastic damping mechanism with nonlinear character...

The weight-transfer effect, consisting of the change in dynamic load distribution between front and rear tractor axles, is one most impairing phenomena for performance, comfort, safety agricultural operations. Excessive weight transfer from to axle can occur during operation or manoeuvring implements connected through three-point hitch (TPH). In this respect, an optimal design TPH ensure better...

The aim of this paper and its sequel is to introduce and classify the holonomy algebras of the projective Tractor connection. This paper analyses the Tractor connection, the various structures it can preserve, and their geometric interpretations. It then presents the projective cone construction, a linking between standard affine holonomy and Tractor holonomy, and uses it to define the complex ...

Agricultural production has clearly benefited from the development of the tractor. The tractor provides a traction device and mobile power source. However, operating large equipment with high clearance on uneven ground leads to stability and overturn issues. Around the world, tractor overturns are still a leading cause of agricultural production fatalities. This special issue of the Journal of ...

The dynamic behaviour of a vehicle (e.g. the dynamic tire forces, the suspension deflection, and the vertical acceleration of the sprung mass) can be improved significantly if the passive suspension is replaced by an active suspension with preview. Preview means that a priori information of the road surface is used in the control of the suspension. In this report, the rear wheels of the tractor...

The aim of this paper and its sequel is to introduce and classify the holonomy algebras of the projective Tractor connection. After a brief historical background, this paper presents and analyses the projective Cartan and Tractor connections, the various structures they can preserve, and their geometric interpretations. Preserved subbundles of the Tractor bundle generate foliations with Ricci-f...

A tractor losing lateral stability starts to rollover. It is a matter of fact that rollover accidents are one the most frequent causes death and injuries for farmers. Consequently, tractors fitted with specific protective structure minimize consequences driver during (ROPS). The narrow-track tractor, designed operate in vineyards orchards, category very narrow track width risk higher. aim study...

Between 1920 and 1939 a nearly six-fold increase occurred in the number of tractors on American farms, from 246,000 tractors in 1920 to 1,445,000 tractors in 1939 [5]. This substantial growth in tractor usage occurred during a period where the role of the tractor in agricultural production was changing. In 1920, the tractor was primarily viewed as the supplier of the peak power needs in spring ...
