Soil Compaction Comparisons
Some farmers have expressed concerns about soil compaction using land rollers.
Mandako-Agri Land Rollers with 5/8" thick, 42" drum weighing 500 lbs. /foot
* If we assume 6 inches are on the ground, then psi = 6.6 psi.
* If we assume 8 inches are on the ground, then psi = 4.9 psi.
Mandako-Agri Land Rollers with a 1/2" thick, 42" drum weighing 500 lbs./foot
* If we assume 5 inches are on the ground, then psi = 6.6 psi.
*If we assume 7 inches are on the ground, then psi = 4.8 psi.
Brillion 20" Cultipackers weighing 175 lbs./foot
* If we assume 3 inches are on the ground, then psi = 4.8 psi.
* If we assume 4 inches are on the ground, then psi = 3.6 psi.
Size 9 shoe:
* If I weigh 160 lbs., soil compaction then = 3.8 psi.
* If I weigh 200 lbs., soil compaction then = 4.8 psi.
* If I weigh 250 lbs., soil compaction then = 5.9 psi.
Size 12 shoe:
* If I weigh 200 lbs., soil compaction then = 4.0 psi.
* If I weigh 250 lbs., soil compaction then = 5.0 psi.
* If I weigh 300 lbs., soil compaction then = 6.0 psi.

Justifying the cost of a Mandako-Agri Land Roller
* Assume the price of soybeans is $11.00/bushel.
* Rental rate of a Mandako Land Roller is $3.50/acre.
* Travelling at 8 mph with a 34' roller, you can do 30 acres/hour.
* Cost of a 160 hp tractor operator at $70.00/hour is $2.34/acre.
So add $3.50 and @ 2.34 = $5.84/acre.
If you can harvest 0.6 more bushel/acre because of smooth ground (rocks, corn stalks, gopher mounds, etc. pushed down) and less sickle and machine maintenance, (save time and costs) is it worth it? ($11.00 x 0.6 = $6.60). That does not consider anything for better germination (which more than likely will improve) along with more efficient weed control.
Also, keep in mind that the flex head will be closer to the ground & harvesting the lower bean pods that previously were missed. This can increase yields and additional 2 to 4 bushels/acre. The lower pods normally produce the best quality beans, and thus, increase profits.
