4.3.5 Biodegradable hydraulic oil
Biodegradable hydraulic oil quality
Use rapeseed oil and synthetic-based HEES biodegradable hydraulic oil with a viscosity in accordance with
ISO VG 32-ISO VG 46.
NOTE:
Polyglycol-based synthetic oils cannot be used.
Maintenance intervals
The oil and oil filter must be changed every 1000 running hours or every year, whichever occurs first.
When switching to biodegradable hydraulic oil, change the hydraulic oil filter after approx. 50–100 running
hours. Since biodegradable hydraulic oil acts as a solvent, any oil residue may block the filter.
Instructions for use
Biodegradable hydraulic oil is suitable for winter temperatures down to approx. -15°C.
Vegetable-based hydraulic oil may thicken in outside temperatures below approx. -15°C or if the tractor is
not used for long periods of time. After a cold start, allow a short warm-up time at medium engine speed
to ensure safe operation of the hydraulic steering and linkage. In extremely low temperatures, it may be
necessary to warm up the entire tractor.
Avoid mixing with mineral oils, e.g. with any oil remaining in the system or by connecting and operating an
external implement. This may affect the positive environmental properties of the fluid, and will make it
more difficult to dispose of (it will then have to be considered as hazardous waste).
Current legislation and the instructions of the oil manufacturer must be observed when disposing of oil.
A mixture containing more than 2% may result in alterations in viscosity and may lead to problems with the
hydraulic valves.
Special features of biodegradable hydraulic oil
Biodegradable hydraulic oil is easily biodegradable and does not effect the ground and groundwater in the
event of accidental spills.
IMPORTANT:
In spite of the high environmental compatibility of biodegradable hydraulic oil, accidental spills must always
be reported.
4.3.6 AdBlue®
General
AdBlue® is a non-combustible, non-toxic, colorless and odorless liquid that is also soluble in water.
Filling and operating vehicles with AdBlue® are necessary in order to comply with emissions regulations,
and therefore constitute part of the tractor's roadworthiness certification. If the tractor is operated without
AdBlue®, the road certificate is rendered void. The legal consequence is that the vehicle can no longer be
operated on public roads.
In certain countries this may be a punishable offence or a minor breach of the law. Benefits when a vehicle
is purchased and/or operated - such as a reduction in tax – may also be retrospectively rendered invalid.
This may be the case in both the country in which the vehicle is registered and another country in which
the vehicle is operated.
