working position ( 1…6 ). The maximum setting is 6. If the setting is increased above 6, the
feeding conveyor speed will not be further increased.
Density of spread material depends on numerous factors: conveyor speed (regulator setting),
blades setting (spread width), travelling speed of the sand spreader, composition of spread
material mixture and its physical properties such as weight, humidity and other. Spreading
density can not be adjusted precisely. This is caused mainly by difficulty in maintaining
constant humidity of spread material as well as various grain size and degree of mixing of
sand-chemicals mixtures.
Figures ( 4.4A ), ( 4.5A ) and ( 4.6A ) show the diagrams presenting relation between spread
material density and the sand spreader speed and setting of spreading adapter blades.
ATTENTION!
While reversing, the sand spreader drive must be disengaged.
Do NOT leave the tractor cab, when the spreading adapter drive and the feeding
mechanism drive are engaged.
Use of the sand spreader with damaged shields is forbidden.
Proper density of spread material can be determined on the basis of presented diagrams. For
example, when blades are set in position (I) – figure ( 4.4A ), in order to achieve spreading
capacity of 200 g/m
2
, set the regulator in position (3). Travel speed of the sand spreader must
be 10 km/h. With such settings of blades and regulator, spreading width will be 2.6 m.
If you want to achieve the maximum spreading width, e.g. 3.8 m with the same output
(spreading density) – 200 g/m
2
, set the blades in position (II) - figure ( 4.5A ). Change the flow
regulator setting to position (6) and increase the sand spreader travel speed to approximately
14 km/h.
Measurements of spreading density were made by Pronar personnel during tests of the sand
spreader and they are the basis for determining operating efficiency of the machine. Results
given should be treated as approximate ones and settings should be selected on the basis of
experience of sand spreader user, taking into account type of spread material and its
properties. Fine sand of medium humidity, without chemicals, was used during the tests.
Switch on the orange beacon light in the tractor before you start spreading. Conveyor belt
and adapter discs are started from the tractor driver's cab, with the aid of the manifold lever.
