2. INTRODUCTION
 This operator's manual should be considered as the machine basic equipment. 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
Arm with flail head is set on tractors with power of min (Tab. 1) 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).
Machine are designed for treatment of land drainage ditches in particular as well as mowing of
road shoulders, shredding thinner trunks (Tab. 2), 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. The
arm can be additionally equipped with adapters offered by the SaMASZ co. Arms work properly on
grass (and other plants) with height up to 1.0 m. Heads are designed for shredding cut tree branches,
mowing weeds, shrubs and grass.
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.
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.

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 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 arm is
done directly from the tractor's hydraulics (KWT 650, Camel 900 with mechanical control) by means
of telescope actuator (13), and 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. Tractor drives
along road’s edge while flail head mows grass.
Use of cylinder (14) controlled rotor (7) enables arm to be set in transport position. Working
arms are protected against overloads by gauge plate cylinder (14) equipped with sweep valve
(item 6.4.7). While head’s cylinder (4) acts as head’s rotation (6).
CAUTION:
Extension of telescopic 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 arm just above the ground.

Operating assembly of extension arm is a flail 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 flail 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°.

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.

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 flail heads Lama 121 and Lama 141
Lama 121/141 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. 20).
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 swiveled every 15° in 4 positions.
3. Swivel push-in fitting, enabling quick coupling/releasing of the head to/from the arm and
allowing the head to be swiveled 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 arm
(Subject: KWT 550/650/651, Camel 900, Koliber 400/450)
Geared pumps power two independent circuits: machine's drive circuit with capacity of
50 l/min and hydraulic cylinders' drive circuit with capacity of 11 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 arm-type
mower's hydraulic engine's drive circuit there is suction oil filter (5) with capacity of 70 l/min. On
gauge plate cylinder (8) there is sweep valve (7) mounted to protect the machine's arms from getting
overloaded (Fig. 21) – 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 arm.
