8.8.1 - Tractor Preparation
Proceed to a general revision in the tractor, in way to make the
planting without interruptions motivated by damages with the tractor -
Remember that your period of planting is short, and it is dependent of climatic
conditions, on which won't have influence. Like this, besides a revision in
the motor and hydraulic system, proceed to a revision of the coupling system
of three point, horizontal arms, vertical arms, tighter, threads of adjustment
of the vertical arms, above all the right arm whose size is adjustable, thread
of adjustment of the arm of the third point, pressure of the tires, there is the
necessity to do a ballasting with water in the tires to improve the traction,
etc.
Verify and adjust the gauge of the tractor (center measure the center
of the tires of the tractor), in agreement with the following rule:
SIMPLE TRACTION TRACTOR
Place the gauge (center to center of the tires) at an equivalent distance
to twice the spacing used among rows.
DOUBLE WHEELED AND SIMPLE TRACTION TRACTOR
Place the gauge (center to center of the external wheels) as near as
possible of an equivalent distance to four times the spacing used among
rows.
SIMPLE WHEELED TRACTOR AND FOUR WHEELS TRACTION
Place the gauge (center to center of the tires) at a distance as near
as possible of an equivalent to twice the spacing used among rows.
Verify the pressure of the tires of the tractor in agreement with the
recommended by the manufacturer, been able if necessary ballast the back
tires with water, given that the traction effort in certain cases is big.
As the planter goes set up in the system of three points of the hydraulic
of the tractor, it is quite natural that the front of the tractor, in certain
circumstances, tend to rise of the soil. To compensate that tendency, the
tractor manufacturers place in the front of the same one a support destined
to support weights, that are used to balance the tractor, should be retired
when they are not necessary. A practical way of being determined the
minimum amount of weights to balance the tractor, is the following: in a
scale, weigh just the wheeled of the front of the tractor, without the coupled
implement. After the coupling, place it in position of transport, in other
words, with the implement in your higher position (completely raised by the
hydraulic system) and weigh again the wheeled of the front.
It should place the necessary weights to obtain, at least, more of the
half of the initial weight.
