Set-up instructions
Preparing the tractor
Before starting the operations, prepare the tractor and equipment appropriately.
Check the general conditions of the tractor, especially the good functioning of the
hydraulic system that must be in flotation mode.
The addition of water ballasts on the tires or a set of weights on the tractor front part
or on the rear wheels are the most used ways to increase the traction over the soil and to
assure a greater stability of the set.
The front and rear wheel gauges must be equal (consider a measure from the center
of the tires).
The reservoir fill-up process must be always done after the daily working period.
This avoids that the air humidity that is inside the reservoir condenses. If filled up, the air
volume inside the reservoir exits through the breather.
The operator must known the tractor operation commands to assure safety,
preservation and integrity of the tractor, as well as to allow an efficient and correct operation.
The PTO activation and deactivation must be done keeping a low rotation speed.
Use equipments which are compatible with the PTO rotation speed.
The option to choose the hole on the third point on the control rod (A) is related to
the type and humidity of the soil and the depth actuation of the equipment. For soils that
have smooth texture and light equipments, use the upper hole.
When working over harder soils or to reach greater depths, the sensibility must be
lowered in order to avoid that the control itself prevents the equipment penetration.
Follow the instructions on the tractor and equipment manual to assure the good
functioning of both of them.

Marchesan Implementos e Máquinas Agrícolas “TATU” S.A. PHT FLEX
For hitching, choose a place as flat as possible.
Drive the tractor slowly in reverse gear to the planter direction and be ready to brake.
When close enough, use the lever to control the hydraulic position, leaving the left lower
arm in the same level of the hitch pin.
1) Hitch the right and left arms, which features ascent and descent movements through
the arm adjuster and place the lock pins. At this moment, the extension thread of the upper
arm can be used to approach or put away the planter to facilitate the hitching.
2) Place the upper arm (third point) and lock it using a lock pin. For a perfect hitching,
the planter must be centralized with the tractor, which is done as follows:
• Align the third point of the planter with the third point of the tractor;
• Totally raise the planter;
• Check if the distances between the lower arms and tires are the same on both sides
(as in "A"), being both in the same level (as in "B").
