1 Motor mower Brielmaier
1.1 Description
Motor mower description The machine is a single-axle attachment carrier for use on steep and flat
terrain.
A 4-stroke petrol engine drives a triple gear pump, which supplies oil
engines for the wheel and mower drive using valve technology.
Each wheel is individually driven by its own hydraulic engine.
Available attachments Various attachments can be fitted to the machine and driven via the
hydraulic connections, e.g.
– Mowing units
– Mulcher
– Rake tedder/rakes
– Snow blowers, snowplough blade
– etc.
All attachments are fitted with a quick-change system.
NOTE
For information on the attachments, refer to the instructions of the
respective attachments.

1.4 Machine elements
1.4.1 Basic configuration
Transport lugs
2
1
The transport lug on the handlebar mounting (1) and the transport lug on
the rod trunnion (2) are used to hold the machine securely in place for
transport.
Rod trunnion
The attachment is coupled and uncoupled at the rod trunnion of the
machine by a quick-release coupling.
Hydraulic block
1
The hydraulic actuators are installed in the hydraulic block.
The hydraulic block includes the proportional pressure control valve "PCV"
(1). It has been fitted as standard since 2019 and enables a soft start as well
as the oil pressure on the attachment to be adjusted.

10 BA Motor mower S250 (Version 2021/09)
Hydraulic oil expansion
tank
The hydraulic oil heats up and expands during operation. The larger
volume is absorbed by the hydraulic oil expansion tank.
NOTICE
Damage to equipment if hydraulic oil is filled in incorrectly.
Filling hydraulic oil into the hydraulic oil expansion tank may cause
damage to equipment.
4Never fill hydraulic oil directly into the hydraulic oil expansion tank.
Steering bar
The control panel and grips are located at the top of the steering bar. The
steering bar can be placed in different positions and individually adapted
to the operator:
– Vertical inclination
– by 200 mm in length
– Upper part of handlebars - bar angle
Combustion engine
The machine is powered by a petrol engine and started by an electric
starter.
Fuel tank
The fuel is filled into the fuel tank:
Super 95E5 (ROZ95)
For filling quantity and specifications, see chapter Technical data [}101].

Brielmaier Motormäher GmbH Motor mower Brielmaier | 1
BA Motor mower S250 (Version 2021/09) 11
Air filter housing
The air filter is located in the air filter housing. The air filter prevents dust
particles from entering the engine.
For cleaning instructions, see chapter Cleaning the intake manifold and
engine oil cooler [}82].
Oil mist separator
The oil mist separator collects the oil droplets captured when the
crankshaft is ventilated and returns the oil to the engine. The air
containing exhaust gases is mixed with the combustion air via the air filter
housing.
Toolbox
1
2
The toolbox (1) contains a tool bag (2) with a selection of the required
tools, the connection plug for charging the battery, the diagnostics
connector, the connections for the radio remote control and electrical
fuses.
Battery
The battery is located in the battery compartment below the toolbox.

Parking support
In order to park the machine safely without an attachment, it is equipped
with a parking support. The parking support can be folded up and down.
NOTICE
Risk of overloading the support foot!
If the support foot is overloaded by lashing, there is a risk of damage to
equipment.
4Do not use the parking support to lash the machine on a loading area.
1.4.2 Options
Tyres Different tyre variants are available depending on the location and
deployment of the machine.
For variants, dimensions, and weights refer to chapter Technical data
[}101].
Spiked rollers
Pneumatic tyres
Terra tyres

Quick-change system for
dual tyres
Different quick-change system models are available for dual tyres.

Work lights
Two work lights can be mounted as a unit on the upper part of the
handlebars.
The work lights are mounted on a magnetic plate. This can be removed
without tools if the lighting is not required. The headlights are connected
via a plug-in contact.
Running board
To ride on the machine, the running board option can be installed below
the handlebars.
The running board is foldable and can also be folded up while driving with
your foot. It does not have to be disassembled to run behind the machine.
Radio remote control
All important functions of the machine and attachments can be controlled
from a distance of up to 100 metres using the radio remote control. If the
radio remote control features a display, the machine's status data is
presented.
NOTE
For more detailed information on the radio remote control, see chapter
Operation with radio remote control (optional) [}69].
Support wheel
The support wheel prevents the machine from tipping backwards when
using the radio remote control. Combination with the folding running
board option is possible.

Handle guard
To protect the hands, an optional handle guard can be mounted on the left
and right of the handles. The handle guard can also be retrofitted on older
machine types.
Fuel pump protective cover
Optionally, a protective cover can be mounted over the fuel pump. This
protects the pump and sensitive components such as cables, connectors and
hoses from mechanical damage.
Intake manifold-
extension
Optionally, an extension piece can be mounted between the intake
manifold on the engine and the air intake grille without tools. Due to the
raised position, the intake grille gets less contaminated.
Underride guard
An underride guard can be fitted as an option to protect against damage
from below. The underride guard can also be retrofitted on older machine
types.

Intermediate plate for the
catch tray offset
1
2
When using spiked rollers with a large diameter, the quick-release coupling
(1) on the attachment must be moved up. When using an extended
mowing unit frame, the quick-release coupling on the attachment must be
moved down. An intermediate plate (2), which is available as an option, is
required for both mounting methods.
Proportional control valves
The standard proportional pressure control valve (PCV) is the right fitting
for most applications.
The proportional pressure control valve (PCV) should only be exchanged for
the proportional flow control valve (FCV) after consulting the
manufacturer/specialist dealer if:
– the speed should be adjustable on the attachment.
– the oil volume of the motor mower (approx. 32 litres/min at 3600 rpm)
is too large for the attachment.
Both proportional control valves allow a soft start of the attachment.
NOTE
We do not recommend a proportional flow valve for attachments
designed for other oil flow rates. Instead, we recommend replacing the
oil engine in the attachment.

1.5 Description of the controls
1.5.1 Basic configuration
Battery disconnector
The battery disconnector is used to disconnect the earth connection
between the battery and machine. To start up the machine, the battery
disconnect key must be inserted and turned 90°.
– Only operate the battery disconnector when the engine is switched off.
– Make sure that the battery disconnector is turned on to charge the
battery.
– If the machine is parked for a long time without charging, switch off
the battery disconnector.
