Mandako Landrollers
Leveling, not Packing!
- Push down rocks with full drum weight
- Level ground receives similar weight to your footstep
Soil Compaction Comparisons
Some farmers have expressed concerns about soil compaction using
land rollers. Take a look at the following information to get a clear
look at what our land rollers actually do.
Mandako Land Rollers with 42 in drums that are 5/8” thick weigh
475lbs per foot.
- If we assume 6 inches are on the ground, then the psi = 6.6 psi.
- If we assume 8 inches are on the ground, then the psi = 4.9 psi.
Mandako Land Rollers with 36 in drums that are 1/2” thick weigh
400lbs per foot.
- If we assume 5 inches are on the ground, then the psi = 6.6 psi.
- If we assume 7 inches are on the ground, then the psi = 4.8 psi.
Brillion 20 inch Cultipackers weigh175 lbs per foot.
- If we assume 3 inches are on the ground, then the psi = 4.8 psi.
- If we assume 4 inches are on the ground, then the psi = 3.6 psi.
Size 9 Shoe If I weigh 160lbs then psi = 3.8
- If I weigh 200lbs then psi = 4.8
- If I weigh 250lbs then psi = 5.9
Size 12 Shoe If I weigh 200lbs then psi = 4.0
- If I weigh 250lbs then psi = 5.0
- If I weigh 300lbs then psi = 6.0
Justify the cost of a Mandako Land Roller
Assume the price of soybeans is $9.00. The rental rate of a land
roller is $4.00 per acre. Traveling at 8mph with a 34-foot roller, you
can do 30 acres an hour. The cost of a 160 hp tractor and operator at
$50.00 per hour is $1.67 per acre. So add $4.00 and $1.67 = $5.76 per
acre.
If you harvest 0.7 more bushels per acre because of the smooth
ground (rocks pushed down, etc.) and less sickle maintenance (save time
and costs) is it worth it? ($9.00 x 0.7 = $6.30) That does
not consider anything for better germination, which is more than likely
to improve.
Mandako Landrollers are heavy-duty units designed to give you uniform packing pressure across the entire width of the roller. Available widths are 12’, 15’, 20’, 30’, 40’, 45’, 50’ and 60'.
Why Mandako Landrollers?
- Achieve better soil to seed contact for better germination.
- Increased yield can pay for the cost of the machine.
- Less sickle maintenance from rock impacts.
- The wings are designed to float and the 2-point adjustable hitch ensures uniform packing pressure in uneven terrain.
