Oil - cutterbar
The following operations must be carried out in a safe and secure way. During all
work near the cutting discs of the machine the tractor engine must be stopped and the
PTO shaft disconnected.
Check the oil level daily in the following way:
● Place the machine on level ground - check the position of the cutterbar with a level as
shown at (A). The bar must be level in this direction. Check also that the cutterbar is level in
the driving direction, shown at (B).
● Remove the oil filler plug. It is situated between the second and third disc on the left hand side
of the machine. Wait for 3 minutes (if the oil is cold: wait for 15 minutes) and check the oil level
using a steel tape measure as shown in (C). Amount of oil from minimum to maximum is about
1 litre (33.8 ozs.) which equals 3 mm (.11”) difference in depth.
Amount of oil: Model HM2007 = 3.5 litres (3.7 qts.) and for following oil change approx. 3.1 litres (3.3 qts.).
Model HM2008 = 4.0 litres (4.2 qts.) and for following oil change approx. 3.6 litres (3.8 qts.).
Model HM2009 = 4.5 litres (4.8 qts.) and for following oil change approx. 4.1 litres (4.3 qts.).
Change of oil: First time after about 10 hours operation and thereafter every 200 hours of opera-
tion or at least once a year. The drain plug for oil is situated on the left hand side
of the cutterbar.
NOTICE
The amount of oil must never exceed the maximum stated. Otherwise the oil will be overheated
and may damage the bearings in the cutterbar.
Oil - bevel gearbox
Check the oil level of the gearbox daily. The gearbox must be level.
Oil level : Plug (D).
Amount of oil: 0.3 litres (10 ozs.).
Change of oil : Change the oil after about 10 hours of operation and thereafter at least once a
season. The oil can be drained through level plug when the cutterbar is in vertical
position.
NOTICE
This transmission rotates at high speed - about 3000 rpm. Therefore, it is important to use
the correct type and amount of oil. Otherwise overheating will occur and damage the trans-
mission. Damage of this kind is excluded from Bush Hog warranty.
At the back of this manual, page 46 “lubricants” are shown. Only use oil types marked (H) for
transmission with such high working speeds.
