All SAM Sprayers are powered by Deutz water-cooled industrial diesel engines. These engines meet all
current E.U. Emission Standards. Power ratings are matched to the gross weight of each machine plus any
extra demand required (e.g. air stream fan).
Two engines cover the Horizon range of SAM Sprayers which are:
Horizon 3000, 3000E, 3500 - TCD6.1 140Kw (188HP)
Horizon 4000, 4000E - TCD6.1 160Kw (212HP)
Horizon 5500, 6000 - TCD6.1 180Kw (242HP)
These are DIN rated outputs and will be approximately 15% more powerful than similar SAE-J rated engines.
This digital engine has been filled with a high quality, fully synthetic oil approved by Deutz. Any oil used in this
engine must be fully synthetic to the same specification. Please refer to the Deutz Operating Manual for oil
specification or contact SAM.
The first Oil & Filter changes are due at 500 Hours.
The radiator header tank is fitted with a level sensor and may produce a low coolant level during the first few
hours of work as the engine cooling system expels air and absorbs water. Check levels and top up as
necessary. The radiator Header Tank is located on top of the engine and accessible without removing guards.
CAUTION- risk of scolding when removing the tank cap!
Behind the left hand Guard are two belts. The wide poly 'V' belt drives the fan, alternator, water pump and
diesel pump. The smaller 'V' belt drives the air-conditioning compressor. The condition and tension of these
belts should be checked according to the maintenance schedule. If a belt slips, it becomes glazed and will fail
to drive correctly, even after it has been correctly re-tensioned. Should this occur then the belt and possibly
the pulley will have to be replaced.
From the Left hand side of the machine the dipstick, oil filler cap, oil filter and fuel filters are available for
service in accordance with the maintenance schedule. The oil filter is located behind the Guard.
Particular attention should be paid to the ‘cooling pack’ located above the engine. Not only should it be
cleaned thoroughly but it should also be 'back blown' to remove any debris wedged between the cooling fins.
The Oil Cooler is thermostatic in operation and will maintain the hydraulic oil temperature above 50C.
It should be noted that hot oil in excess of 80 deg C would severely damage the hydrostatic system causing
unnecessary expense. The regularity at which the engine/oil cooler is cleaned will depend entirely on the
working conditions. When working in oil seed rape for example, it may need cleaning more than once daily.
Only the operator can decide.
A visual inspection should be carried out daily.

The Steering and Self-Levelling Suspension Systems run from the Load Sense Hydraulic Circuit. The
Pressure Relief Valve in the steering unit is pre-set to 170 bar (2450 psi).
