2. INTRODUCTION
 This operator's manual should be considered as the machine basic equipment machine and should
be kept for future use. If the mower is handed over to another operator, it should be in working
condition, along with operator's manual, EC declaration of conformity and its basic equipment.
 Prior to operating the machine its user must familiarize himself with this manual as well as common
work safety rules.
 The machine is manufactured in accordance with requirements of safety standards.
 Respecting recommendations herein shall ensure operation safety.
 If you have any questions related to commission and operation of the machine, please contact
the manufacturer.
 This operator’s manual is an indispensable part of any machine and is intended to familiarize a
machine user with principles of proper operation and use of the machine as well as the risks
involved.
GENERAL PRECAUTION
When operating the machine warnings and safety rules marked with this sign
herein should be respected.
CAUTION!
Operating the machine without previous familiarizing with its content as well
as by unauthorized personnel, and especially by children, is strictly forbidden.
3. PROPER 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.
CAUTION!
Use of the machine for purposes other than mentioned herein is forbidden.
Different use than the above mentioned shall be considered as improper and
may lead to revoking of the warranty. The machine should be operated,
maintained and repaired only by personnel familiarized with its detailed
specifications and safety rules and procedures. Willful modifications to the
machine may lead to revoking of the warranty.

CAUTION!
Basing on experience, upon driving onto single shrub with section up to approx.
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.
3.1. Technical data

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.

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 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).

1 - Fixed mounting, 2 – Rotary mounting, 3 – Hydraulic turntable,
4 – Mounting ground following linkage, 5 – Mowing head ground-following linkage

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. KOLIBER 400 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.
