OPERATOR’S MANUAL
2. INTRODUCTION
❑This operator's manual should be considered the machine's basic equipment and should be kept
for further reference. If the machine is handed over to another user, it should be serviceable, and
include this operator's manual, CE declaration of conformity and its required basic equipment.
❑Before operating the machine its user must familiarize himself with this manual as well as current
work safety rules.
❑The machine is manufactured according to international safety rules.
❑Respecting recommendations herein shall ensure use safety.
❑Should you have any questions relating to the operation and service of the machine, please contact
the manufacturer.
GENERAL PRECAUTION
When operating the machine warnings and safety rules marked with this sign
herein should be respected.
NOTE:
Operating the machine without reading the contents of the manual, and by unauthorized
personnel, children in particular, is strictly forbidden.
3. INTENDED USE
The extension arm can be equipped with mowing heads offered by the SaMASZ co. Machine are
designed for treatment of land drainage ditches in particular as well as mowing of road shoulders,
shredding thinner, small shrubs, weeds, etc. of moderate concentration as well as mowing road
shoulders, slopes, counter-slopes and ground at tractor's right side. Moreover the mower can be used
to trim hedges both in vertical and in horizontal position. Extension arms work properly on grass (and
other plants) with height up to 1.0 m.
Extension arms are mounted on tractors of adequate power (Tab. 1, Tab. 2, Tab. 3). Mounting
the arm is performed on rear 3-point linkage, with which are farming tractors equipped as standard.
Rear PTO must be set on 540 rpm (upon special order 1000 rpm). When operating a tractor with 1000
rpm PTO shaft adjust the rpm so that the shaft rotates at 540 rpm. Thus the operation becomes
economic.
CAUTION!
With such setting make sure the PTO shaft rpm is no higher than 540 rpm.
WARNING!
Do not use the machine for purposes other than those listed in this manual.
Otherwise it will be classified as misuse and could release the manufacturer
from responsibility for any damages. The machine should be used, serviced and
repaired only by personnel familiar with its characteristics and with safety
regulations. Tampering with the machine may release the manufacturer from
responsibility for any resulting malfunctions or damages.
CAUTION!
Basing on experience, upon driving onto single shrub with section up to approx.
1 in / 2 cm, the tractor should be stopped for a while, until the machine shreds
the shrub at the ground, and then slowly with intervals drive forward, so there
occurs no cutterbar locking.

Fig. 11.Overview of KWT 651 extension arm
Extension arm is equipped with independent hydraulics with oil cooler and oil tank (9). Rotor’s
drive and extension arm control is possible owing to own hydraulic pumps assembly driven by multiplier
(10), transmitter’s shaft without coupling and tractor’s PTO. Controlling extension of telescopic
extension arm is done directly from the tractor's hydraulics (KWT 650, CAMEL 900 with mechanical
control) by means of telescope actuator (13), and extension arms are moved with hydraulic actuators
(1and 2).
Controlling operation of extension arms is performed from tractor’s cabin with use of control
panel (15), equipped with a cylinder control handle and a joystick (1, 2, 4 and 14). With use of
corresponding handles, the operator can set position of machine’s movable assemblies.
Use of cylinder (14) controlled rotor (7) enables extension arm to be set in transport position.
Working extension arms are protected against overloads by gauge plate cylinder (14) equipped with
sweep valve (item 6.5.7). While head’s cylinder (4) acts as head’s rotation (6).
CAUTION!
Extension of telescopic extension arm causes shifting of centre of gravity of the
set (tractor, machine) what may cause alternation of its stability. It is
recommended to extend the extension arm just above the ground.

3.2.2. Mowing head
All mowing heads (KW, LAMA) adjusted to operate with extension arms have similar
construction. Construction scheme of mowing head is provided in Fig. 15.
Operating assembly of extension arm is a mowing head (6), which comprises flail bar (20) with
flail knives (21) for different purposes (item 6.4), screwed with mounting bolts (knife type depends of
kind of surface mowed (grass, bushes, hay, cornstalks). Flail shaft (20) of mowing head is driven by
hydraulic engine (23). Ground following bar (22) features mowing height adjustment function
(item 6.3). It is protected with metal sheet guards from each side. Cutterbar can be rotated in relation
to linkage axis by approx. 230°.

LAMA 121/141 head comprises flail shaft (20) with flail knives (21) of different application
(Section 6.4) mounted with mounting screws (knife type depending on type of material cut: grass,
shrubs, straw, corn stalks). Flail shaft (20) of mowing head is driven by hydraulic motor (23) through
belt gear (24) with v-belt. Ground following roller (22) has mowing height adjustment function.

LAMA 101P (Fig. 17) –mowing head with ejection comprises flail shaft (20) with flail knives (21)
mounted with mounting screws. Alike KW and LAMA heads, the flail shaft (20) of mowing head is driven
by hydraulic motor (23). Ground following shaft (22) has mowing height adjustment function (Section
6.3). Ejector (19) comprises a fixed and a movable part, and the latter is controlled with hydraulic motor
driven directly from the tractor's hydraulics.

KW 111/126/141 (Fig. 18) –mowing head consists of flail shaft (20) with flail knives (21)
dedicated for various purposes (flail type depends on the type of cut material: grass, bushes, straw,
corn stalks). Machine is equipped with adjustable counter-knife (25). Flail shaft is powered by hydro-
motor (23) and power is transferred through speed-belt gear (24). Slide bar is a part of the machine and
the plate mount (27) can be easily adjusted. Ground shaft (22) has a cutting height adjustment function.

3.2.3. Mounting mowing heads
LAMA 121(HD)/141 and KW 111/126/141 heads are attached to an extension arm with a
standard single or 4 optional types of fittings available, which enable different manners of mounting
the head (Fig. 19).
Fittings are of the following types:
1. The basic is a rigid fitting, simple and light, attached to an extension arm with 6 screws M14
(SaMASZ-standard).
2. Swivel fitting, mounted with 6 screws M14 (SaMASZ-standard) to an extension arm, enables the
head to be swivelled every 15° in 4 positions.
3. Swivel push-in fitting, enabling quick coupling/releasing of the head to/from the extension arm and
allowing the head to be swivelled every 15° in 4 positions.
4. Mounting for ground-following linkage, connected to extension arm with 6 bolts M14.
5. Mowing head ground-following linkage. Extension for mechanical ground following with 260mm
travel. Mounted on extension arm with 6 bolts M14 (SaMASZ standard).

3.3. Characteristics of hydraulics of extension arm
Cable-type steering
(Subject: KWT 550/650, CAMEL 900, KOLIBER 400/450)
Geared pumps power two independent circuits: machine's drive circuit with capacity of 100 l/min
and hydraulic cylinders' drive circuit with capacity of 21 l/min. In machine's drive circuits wires have
16 mm diameter, while in cylinders' control circuit 10 mm. Control of oil circulation is possible
owing to hydraulic distributors (3, 6). Oil tank (4) of adequate capacity. In extension arm-type mower's
hydraulic engine's drive circuit there is suction oil filter (5). On gauge plate cylinder (8) there is sweep
valve (7) mounted to protect the machine's extension arms from getting overloaded (Fig. 20) –applies
only to KWT 550, KWT 650 and CAMEL 900. KOLIBER400 and KOLIBER 450 instead of gauge plate
cylinder (8) both have overload breaker. Hydraulic cylinders (8-11) with throttle choke valves (12)
control the extension arm.
