| Box options |
Two-bin capable of 50/50 or 60/40 split |
| Conveyor |
Dual conveyors (left and right) with stainless-steel chain |
| Oiler |
None |
| Gate height physical adjustable range |
2.5-5.3 cm
1-2.1 in.
NOTE: The gate is set from the factory at 3.8 cm (1.5 in.). It is not recommended to adjust the gate height below 3.8 cm (1.5 in.) as operators may experience conveyor performance issues such as belt stalling or it may affect rate accuracy. |
| Controllable conveyer rpm range |
Bin 1 and Bin 2 running separately: 2-70 rpm
Bin 1 and Bin 2 running at the same time: 2-40 rpm |
| Conveyor application rates |
56-1345 kg/ha
50-1200 lb per acre
*Assuming 16.1-km/h (10-mph) vehicle speed, 1041.2 kg/m3 (65 lb/cu ft) material, and 3.8-cm (1.5-in.) gate height. This also assumes CFR 0.2758.
NOTE: 1345 kg/ha (1200 lb/acre) is the maximum rate between all bins with the assumptions listed above. 56 kg/ha (50 lb/acre) is the minimum rate from a single bin (1 or 2) with the assumptions listed above. |
| Controllable metering rpm |
Bin 3 (granular bin): 3-61 rpm |
| Metering application rates |
6.7-139 kg/ha
6-124 lb per acre
*Assuming a yellow metering roller, 16.1-km/h (10-mph) vehicle speed, and 1041.2 kg/m3 (65 lb/cu ft) material. This also assumes a CFR of 0.0442. |
| Volumetric flow rate |
Less than 0.74 m3/min
26.1 cu ft/min
NOTE: Plugging of booms may occur if the sum of the flow rate of all bins is greater than spec. NOTE: To calculate the volumetric flow rate per bin: volumetric flow rate (cu ft/min) = (rate (lb/acre) x speed (MPH) x 0.1414)/density (cu ft). Constant of 0.1414 assumes 21.3-m (70-ft) spreading width. |
