12.8. The tractor pulls in the direction of ploughing:
The load transmission of the front part of the tractor
is not sufficient. See the GB standard of «hydraulic compensation
cylinder» as optional possibility to get 30% reduction of
slipping.
See chapter 9: «Adjusting on the field - second
course».
The lifting arms of the tractor are not fastened. Check if the lifting arms are fastened sufficiently on
every side to prevent the plough head oscillation.
The first furrow is too wide and deflects the tractor. Reduce the working width of the front plough bottom.
The earth is too adherent Reduce the ploughing width.
The tractor pulls in the direction of ploughing (continuation):
The tractor is not heavy enough. Load the tractor (ballast the front part, front and rear
wheels balancing, blowing up with water, talc, lime
powder).
See chapter 4: «The tractor preparation for pulling».
The penetration angel of the plough bottoms is too
big. Reduce the penetration angel at every plough bottom.
See chapter 9: «Adjusting on the field - second
course».
The tyres of the front wheels have bigger distance
than the rear wheels. Check and adjust the distance between the front and
rear tyres.
See chapter 4: «The tractor preparation for pulling».
The tyre span is not sufficient taken into the
consideration the number of the plough bottoms
(inner distance of the inner tyres). Increase the tractor span (the inner distance of the
inner tyres).
In the case of
≥
6 plough bottoms the wider the span
the better the pulling.
See chapter 4: «The tractor preparation for pulling».
12.9. The furrows are not straight:
The hydraulic adjustment of the plough on the front
staff are not in the phase with the rear plough
bottom.
There is air in the circuit. Synchronize the working width of the front and rear staff
expelling the air out of the hydraulic system.
See chapter 9: «Adjusting on the field - second
course».
The plough is not horizontal.
The tractor lifting arms are not of the same length. Check the length and blocking of two lifting arms axles.
See chapter 4: «The tractor preparation for pulling».
The plough is not horizontal
Inclination angle is not suitable. Adjust the boots of inclination angle.
See chapter 9: «Adjusting on the field – second
course».
The plough is not horizontal.
The level adjusting of the fore-and aft direction is not
suitable. Adjust the boots of inclination angle.
See chapter 9: «Adjusting on the field – second
course».
The plough bottoms are not suitably cleaned (newer
rusted ones).
The ground adheres to the breasts Clear away the paint, scrap the rust and ground from
the breasts.
See chapter 7: «Preparations of the plough before the
operation». See chapter10: «Lubrication and
maintenance».
The tractor tyres are too wide (
≥
650 mm) and tread
down ploughing.
Mount the lengthening pieces of the breast to throw soil
as far as possible.
Mount the furrow widening to the last plough bottom to
help the tractor wheels moving in the furrows.
The hydraulic securities are too often disengaged. Raise the pressure in the hydraulic accumulator.
The wheels of the central bearing tread down the
ploughing. Adjust the span of the central bearing wheels.
See chapter 9: «Adjusting on the fields».
The plough sole fasteners have been worn or
missed. Check and if it is necessary change them.
The coulters are worn and are not able to cut proper
soil pieces. Change the coulters.
