A two wheel drive tractor, weighing 15.84 kN with a wheel base of 2160...
° above the horizontal through the hitch point.
To find the horizontal and vertical components of the pull force, we can use trigonometry:
horizontal component = pull force x cos(12°)
vertical component = pull force x sin(12°)
We don't know the value of the pull force, but we can find it by considering the equilibrium of forces on the tractor. The weight of the tractor acts downwards through its center of gravity, which is located at a distance of 1080 mm from the rear axle (since the weight is divided in a 30:70 ratio). The weight creates a moment (torque) about the rear axle, which is balanced by the moment created by the pull force about the same point:
weight x distance from rear axle = pull force x distance from rear axle
15.84 kN x (0.7 x 2160 mm) = pull force x (120 mm)
pull force = (15.84 kN x 0.7 x 2160 mm) / 120 mm
pull force = 211.25 kN
Now we can calculate the horizontal and vertical components of the pull force:
horizontal component = 211.25 kN x cos(12°) = 203.57 kN
vertical component = 211.25 kN x sin(12°) = 46.59 kN
The horizontal component represents the force that propels the tractor forwards, while the vertical component represents the force that lifts the front wheels off the ground. The ratio of these two forces is:
force ratio = vertical component / horizontal component
force ratio = 46.59 kN / 203.57 kN
force ratio = 0.229
This means that for every 1 kN of force that propels the tractor forwards, there is 0.229 kN of force lifting the front wheels off the ground. In other words, the tractor is not very well balanced for pulling, and may have traction problems if the ground is not level or has uneven traction.
To find the horizontal and vertical components of the pull force, we can use trigonometry:

pull force = (15.84 kN x 0.7 x 2160 mm) / 120 mm
pull force = 211.25 kN
Now we can calculate the horizontal and vertical components of the pull force:
horizontal component = 211.25 kN x cos(12°) = 203.57 kN
vertical component = 211.25 kN x sin(12°) = 46.59 kN
The horizontal component represents the force that propels the tractor forwards, while the vertical component represents the force that lifts the front wheels off the ground. The ratio of these two forces is:
force ratio = vertical component / horizontal component
force ratio = 46.59 kN / 203.57 kN
force ratio = 0.229
This means that for every 1 kN of force that propels the tractor forwards, there is 0.229 kN of force lifting the front wheels off the ground. In other words, the tractor is not very well balanced for pulling, and may have traction problems if the ground is not level or has uneven traction.
