The PST4 planter is specially designed to perform no-till or
conventional planting of corn, soybean, rice, bean, peanut, cotton with
linter, delinted cotton, sorghum and others with superior quality.
It features 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 this equipment is the wide, anti-slip, articulating
platform, that comes with an extensor to facilitate the filling process by
the side of the planter.
It has an articulating ladder with handrail that follows the NBR
standards.
This instructions 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

Fasten the unaligned double disc (A) to the seed row arm (B) using bolts (C), spring
washers and nuts.
Couple the hopper (D) that has a quick locking (E). To avoid damages to the quick
locking and seed disc locking, never overtight the quick lock adjuster (F) and leave it facing
the threaded stud of the quick lock (G). If the adjuster gets loose, fasten the thread until it
tighten properly. Overtightening it may break the quick locking and disc locking.
