Slope Grade Profiles

A - 9% Grade (5 degrees)

B - 18% Grade (10 degrees)

C - 27% Grade (15 degrees)

D - Flat Ground

1910 Air Cart Rear Hitch	Capacity	9979 kg (22 000 lb)

For the unlisted seeding tools use the following rules:

For slopes up to 9% Grade (5 degrees) (A):

• Total weight of towed implement must not exceed the rear hitch capacity on the air cart.
• Combined weight of the loaded cart plus the towed implement must not exceed the rated capacity of the rear hitch on the seeding tool.

For slopes from 9% to 18% Grade (10 degrees) (B):

• Total weight of the towed implement must not exceed 0.5 times the seeding tool weight or exceed the rear hitch capacity on the air cart.
• Combined weight of loaded cart plus the towed implement must not exceed 2.5 times the seeding tool weight.
• Combined weight of loaded cart plus the towed implement must not exceed the rated capacity of the rear hitch on the seeding tool.

For slopes from 18% to 27% Grade (10—15 degrees):

• Total weight of the towed implement must not exceed 0.5 times the seeding tool weight or exceed the rear hitch capacity on the air cart.
• Combined weight of loaded cart plus the towed implement must not exceed 2.0 times the seeding tool weight.
• Combined weight of loaded cart plus the towed implement must not exceed the rated capacity of the rear hitch on the seeding tool.

For slopes above 27% Grade (15 degrees) (C):

• Tow-Behind carts are not compatible with slopes above 27% grade.

The tank fill levels for road transport are less than field fill levels. (See Calculate Maximum Commodity Weight for Road transport.)
