Introduction
PST DUO FLEX and PST DUO FLEX SUPREMA planters were specially
designed to work on rough soils that have level curves and also to work on
broad-based terraces, assuring a greater uniformity in the depth of the row
units.
They feature depth control, that along with the unaligned double discs,
provides a soil compaction with higher efficiency and a better flow rate of
straw. It can be adjusted without using any tool.
Equipped with a fertilizer metering that has an auger with internal coating,
which ensures a greater precision and uniformity in the metering process.
Another advantage of these planters are the wide, anti-slip, articulating
platform to facilitate the filling process.
The self-lubricative bushings technology on the row units assures a better
performance.
They have an articulating ladder with handrail that follows the NBR
standards.
They also have independent and sequential hydraulic markers, which
have length and disc angle adjustments.
This operator's manual contains the necessary information for the best
performance of this planter. The operator must carefully read the entire manual
before working with the equipment. Also, read and understand the safety
recommendations.
For any further explanation or in the case of technical problems that
may arise during the service, consult your dealer and the Technical Support
department of the factory. They can ensure the fully functioning of your TATU
planter.
