6.2.2 By the manner of unitizing with the tractor, agricultural machines are divided into the
following types:
MOUNTED
—
fixed at three points to the joints of the HL upper and lower rods.
The
machine weight of in the transport position is fully borne by the tractor. Components of the
machine in the transport position have no contact with the supporting surface. When
transferring the machine from working to transport position, the point of junction of the
machine with the tractor is moved forcedly to a new height.
SEMI-MOUNTED
—
is fixed at three points to the joints of the HL upper and lower rods
or only two points to the joints of the HL lower rods.
The machine weight in the transport
position is partially borne by the tractor and mostly by own road wheels (usually one or
two). When transferring the machine from working to transport position, the point of
junction of the machine with the tractor is moved forcedly to a new height. The two-point
joint coupling is done by attaching the connecting fingers of the suspension axle of the
machine with the joints of the HL lower rods (the upper rod is not used). The option of
using a cross-beam supplied with the tractor or the machine is possible.
SEMI-TRAILED — usually attached at one point through a drag ring to the TC.
The
option of a two-point joint connection with the HL is possible (without using the upper
rod). The machine weight in the transport position is partially borne by the tractor and
mostly by own road wheels (usually two or more). When transferring the machine from
working to transport position, the point of junction of the machine with the tractor does not
change its position. To semi-trailed machines, also various general-purpose and special
transportation tools belong such as: general-purpose semi-trailers, tank semi-trailers, dump
semi-trailers and semi-trailed special vehicles for mechanization of processes in agriculture.
A particular example of semi-trailed machines are technical tools unitized with used of
saddle-type coupling devices.
TRAILED
—
usually attached at one point through a drag ring to the TC.
The option of a
two-point joint connection with the HL is possible (without using the upper rod). The
machine weight in the transport position is fully borne by its own running gear, the coupler
of the tractor (TC or HL) bears only the weight of the machine coupling device. When
transferring the machine from working to transport position, the point of junction of the
machine with the tractor does not change its position. To trailed machines, also various
general-purpose and special transportation tools belong such as: general-purpose trailers,
tank trailers, dump trailers and trailed special vehicles for mechanization of processes in
agriculture. When unitizing mounted, trailed, semi-mounted and semi-mounted machines, it
is allowed to fasten their individual elements (SAK panels, markers, limit rods, fasteners,
brackets, etc.) subject to observing all guidelines in the operating manual.
