The Husqvarna PG 530 comes equipped with Dual 
Drive Technology™. As the grinding discs are driven 
by the large motor via an internal belt, and because the 
belt is sealed inside the machine, there is no mainte-
nance regarding this drive system until a major service 
(belt and bearing replacement) is due. This is typically 
following 12-36 months of operation.

The second component to the Dual Drive Technol-
ogy™ system is the planetary head drive system which 
is    powered by the secondary or small motor and 
gearbox arrangement. This system is on the outside of 
the machine and will require routine maintenance.

The planetary drive system can be seen as illustrated

Lubrication of this system will cause dust to 
build up in chain ring and drastically shorten the 
life of both the chain ring and planetary drive 
sprocket.

Beneath the gearbox and concealed by the mounting 
brackets and machine cover, there is a planetary drive 
sprocket situated on the output shaft of the gearbox. 
This planetary sprocket engages with the chain ring 
(also      located beneath the machine cover) and 
together form the main drive mechanism for the plan-
etary drive system. This system is a dry system (i.e. it 
is not required for there to be lubrication between the 
planetary drive sprocket and chain ring), to allow any 
dust that may come into contact with the chain ring to 
fall back out again.

The chain ring and planetary drive sprocket are located 
beneath the cover of the machine, however on the 
outside of the machine, there lies the potential that they 
can be exposed to dust and other debris created during 
the grinding process. In order to prevent this as much 
as possible, a planetary seal  has been installed to stop 
dust and other particles from coming into contact with the 
planetary drive mechanism.
