II. TECHNICAL DESCRIPTION
USE
The SAMSON-56 dis grass cutter has been designed for mowing high grass of all
inds of grass growth. Ta ing into consideration the proper technical execution of the
machine it has been designated to serve for larger areas and is particularly suitable
for professional use.
WARNING : This machine can not be used as a mower for par treatment of
grass-plots! It has been designed to serve for mowing high grass vegetation.
On the mowing dis there are three pivoted mowing blades made of high-quality steel
provided with a hardened cutting edge by means of which the mowed vegetation is
perfectly mown.
The mown growth is thrown aside by the rotating dis . An apron preventing the
vegetation from being thrown aside forms at the same time an edge from the mown
vegetation.
DSK-316 series gear boxes driven by JM 4 - 003 and PJ - 5 driving units have been
designed to drive this machine.
It is not possible that driving units DMJ - 315 be used for the drive. The dis mower in
connection with gear box DSK - 316 and this driving unit are not balanced, therefore,
it relieves the mowing dis which then results in poor-quality mowing of the
vegetation.
WARNING : the circumferential velocity of the wor ing blade ends is
57,5 m.s-1
Solid bodies sprung bac by the wor ing blades may fly very far!
Observe, therefore, basic safety regulations when operating this machine. The
machine is fitted with a rotating wor ing dis .
While wor ing with this machine see to it that other persons are at a safe
d stance from the mach ne!

TECHNICAL DESCRIPTION :
Dr ve: the drive is a supporting component of the whole machine. The drive body is a
grey cast iron casting with machined function surfaces. The case cover is fitted on the
body with four screws. The drive shaft is mounted on antifriction bearings in the drive
body. A bevel gear wheel is mounted on the front end. On the bottom end of the bevel
pinion which is mounted in the case cover on two ball bearings and one needle bearing
there is a rotating dis provided with three mowing blades which is carried along by
means of a feather. The bottom dis is pivoted on ball bearings.
The mowing blades are pivoted on the circumference of the rotating dis . The screws
of the rotating dis s are made of high-quality high-strength steel .
Oil is filled through an oil filling hole fitted with a plug.
Cover: the drive is fitted with a cover made of ABS plastic. The cover ensures the
discharge of mown vegetation out of the machine. Rubber aprons are screwed on to
the rear part of the cover, as well as a handrail for handling the machine and a rubber
apron preventing mown vegetation from flying off between the power assist wheels.
The side apron is fitted to a holder which is fitted in a rectangular tube located on the
rear part of the machine cover and it is secured by means of two screws.
A cast iron weight with a mass of 6 g is screwed on the cover to ensure a better
balance which is necessary for a better copying terrain by the rotating dis of the
machine, particularly in cases of a mar edly uneven terrain.
