Horizontal and vertical convergence distance :
Horizontal and vertical convergence distance
Horizontal convergence distance :
Horizontal convergence distance Important for the horizontal stability of implements.
If the horizontal convergence distance is too large, the lateral stability of directional implements is decreased and leads to uneven furrow
If the horizontal convergence distance is too short, non-directional implements, such as harrows, easily find equilibrium positions somewhat asymmetric to the tractor and leads to poor quality of work.
Slide 9:
Experience shows that most implements will function well with the following horizontal convergence distance:
Category 1: 1,700 mm to 2,400 mm
Category 2: 1,800 mm to 2,400 mm
Category 3: 1,900 mm to 2,700 mm
Category 4: 1,900 mm to 2,800 mm
Vertical convergence distance :
Vertical convergence distance The vertical convergence distance is important for stable working conditions and makes it possible
to reduce the influence of tractor movements on connected implements;
to provide for wide interchangeability of tractors and implements designed by different producers.
To achieve these properties for a linkage, it is recommended that the vertical convergence distance is not less than 0.9 times the tractor wheelbase.
