blackberries and various other weeds.
Any use of this riding mower, which is not described in this user's manual and which
goes beyond the use here described is considered to be in contradiction to its
intended purpose or use. The manufacturer of the machine is not responsible for damages
arising from such use; the risk is borne by its user. The user is also responsible for adhering
to the conditions prescribed by the manufacturer for the operation, maintenance and repairs
of this machine, which may only be used, maintained and repaired by persons that
know these conditions and have been informed about possible dangers.
Only accessories, which have been approved by the manufacturer may be connected

1.2 MAIN PARTS OF THE RIDING MOWER
Riding mower models AC 92-18, AC 92-20 or AC 92-23 4x4 consist of the following basic sections:
(1) Hood with storage space
The hood is a combination of plastic and metal covers, which contain the storage space for
the battery.
(2) Frame with a bumper
The frame with the bumper serve as a bearing element for most of the main parts of the
machine.
(3) Front axle with wheels including steering*
The front axle enables the wheels to turn. The wheels are turned by the steering wheel by
means of a comb mechanism.
The AC 92-23 4x4 machine is equipped with front-wheel drive. All-wheel drive is activated
automatically, with power distributed to the individual axles depending on the current
traction conditions and the travel mode (forward or reverse).
(4) Mower deck
The mower deck mows the grass. It is located under the machine. It consists of a cover,
1.2
main plate, blade holders and two massive mowing blades. The deck is powered by the
machine's engine through an electromagnetic clutch and a V-belt.
(5) Engine, gear box including rear-wheel drive via a by-pass
The four-stroke petrol engine is mounted to the frame in the rear part of the machine. The gear
box with hydrostatic power transmission serves to change gears while driving. The by-pass lever is
located on the machine's rear plate. It serves to activate and disable the gear box for the rear wheels.
(6) Folding frame of the machine
The folding frame is intended to prevent the machine from rolling over by 180° if for any
reason it loses stability and rolls on to its side.
(7) Driver's location
The comfortable seat enables easy access to all control elements on the machine. The seat
used ensures safe and comfortable operation.
*ATTENTION: The AC92-23 4x4 machine does not enable for construction reasons the
disconnection of the front axle drive – the hydraulic system is not equipped with a by-
pass valve, which significantly limits the option of moving the machine when the engine
is not running. During such movement the front axle is significantly overloaded and may
be damaged. The by-pass lever on this machine is primarily used to bleed the hydrostatic
system. The machine must not be used (gear shifted into drive) if the by-pass lever is in the
disengaged position - there is a danger of damage to the transmissions!!
