Determining Tow-Behind (TBH) Commodity Cart/Seeding Tool Compatibility
|
Total cart weight with product needs to be calculated and compared to seeding tool weight to determine if they can be operated together in either flat or sloped operations.
-
For slopes up to 18% Grade (10 degrees), total weight of the cart plus material should not exceed 2.5 times the seeding tool weight.
-
For slopes between 18%-27% Grade (10-15 degrees) total weight of the cart plus material should not exceed two times the seeding tool weight.
-
For slopes above 27% Grade (15 degrees), Tow-Behind carts should not be used.
|
IMPORTANT:

1.
Locate cart size/model and approximate weight in the chart.
NOTE:
Grain weight of 60 lbs-per-bushel was used for calculation. Fertilizer calculations used 77 lbs-per-bushel. Your product density may be different.

NOTE:
If seeding tool is not listed on chart, or was not manufactured by John Deere, refer to your seeding tool operator's manual for weight.
2.
Multiply seeding tool weight by 2 or 2.5, depending on operational slope grade (degrees) to determine if cart weight exceeds allowable maximum.
NOTE:
Example uses a John Deere 9.5 m (31 ft) 735 Seeding Tool and 195 Bushel Tow-Behind Cart with fertilizer in both tanks.
-
For slopes up to 18% grade (10 degrees):
Seeding Tool Weight x 2.5 = Maximum Cart Weight 5625 kg (12,400 lb) x 2.5 = 14,061 kg (31,000 lb).
-
For slopes between 18%-27% grade (10-15 degrees):
|
Seeding Tool Weight x 2 = Maximum Cart Weight 5625 kg (12,400 lb) x 2 = 11,249 kg (24,800 lb).
3.
Based on the calculations, example machine combination can be used on slopes up to 18% grade (10 degrees), as the actual weight of the cart with product 10,439 kg (23,015 lb) is less than the calculated maximum weight 14,061 kg (31,000 lb).
This machine combination can be used on slopes between 18%-27% grade (10-15 degrees) as the cart weight with product 10,439 kg (23,015 lb) does not exceed the maximum allowable weight 11,249 kg (24,800 lb) for this operating condition.

|
When cart weight with product exceeds calculated maximum weight, product level will need to be reduced to lower cart weight into compliance. Take
|
a density reading of the product in use, determine kg/L (lb/bushel), and reduce percent-of-fill accordingly.
