3.3.2 Description of the machine and its parts
Drum mower Agatha (
Pict.2
) is built on a steel frame, to which all important parts of the machine are attached. All controls 1 , 2
and 4 are placed on the handlebars. Handlebars are attached to the frame with a bolted connection 3 and their height is adjustable
into 6 positions. Handles 12 secure a firm grip and machine handling during work. On the left side of the handlebars, there is the wheel
drive clutch lever 2 which controls the movement of the machine in forward direction. On the right side, there is lever 1 of the disc
drive clutch for turning the cutting disk drive on (off). Both control levers return to their original position when the handlebars are released
in a critical situation and disconnect the engine power transfer. The cutting disk is equipped with an automatic brake
80
which stops the
disk. Engine speed is controlled with an accelerator lever 4 . The wheel drive is controlled by worm-gear unit with a belt clutch which
provides fluent power transfer onto the wheels 15 (the machine does not start with a jump). The gearbox and clutch are covered by a
plastic gearbox cover 16 . There is the cutting disk 7 with four steel blades 8 in the front part. The attendant is protected against
flying parts of the cut stand by cover 10 and 9 . A detachable side screen 6 , which is attached with a bolted connection 5 ,
controls the line spacing.
3.4 User guide
3.4.1 Assembling the machine
As part of the pre-sale servicing, ask your dealer to unwrap the machine and give you a brief training on
how to use it!
Places for holding the cutter while removing it from the box (see
Pict.1
): by the cutting disc in the front 4 , by the machine frame tube
in the back 1 .
3.4.1.1 Assembling procedure
Use the following procedure for assembling the machine:
(It is advised to assemble the machine with a second person’s assistance)
1) According
Pict.1
- take the disc cover 3 , bag 6 , side and rear screens 7 and a screen holder 2 out of the box. Pick the
machine up by its lift points in front 4 and back 1 and take it out of the box.
2) According
Pict.2
- dismount the bolted connection 3 on both sides of the frame, take off the handlebars, turn them around
and put them on the frame as shown in the picture (choose one of the 3 holes in the handlebars to set their height). Re-tighten
the bolted connection firmly with your hand. Control lever cables must not be crossed - this shortens their lifetime!
3) Take the draw bands out of the bag and tighten brake cables to the handlebars where the upper bending of the handlebars
tube ends. Two pieces of draw bands are sufficient for cable tightening.
4) Dismount the self-locking nuts
81
M5 (2 pieces) and washers, mounted by the manufacturer, off the frame and set the disc
cover on the machine so that the holes fit in the screws in the frame, and the narrowed part of the cover is pushed in under the
engine plate. Put the washers and self-locking nuts M5 back on the screws and tighten them.
