4/18/2021 – Bought 2020 LMC Fertilizer Spreader
- Model US-340
- Stock No. 303012 at SunSouth for $750 + $60 tax = $810.
- Product ID No. 20-000489
| Gear with PTO at 540 RPM | Secs for 200′ | FPS | MPH |
|---|---|---|---|
| 1H | 37 | 5.45 | 3.7 |
| 2H | 27 | 7.4 | 5.05 |
| 3H Too Fast | 18.2 | 11 | 7.5 |
| 4M | 61 | 3.27 | 2.23 |
Measured 4 quarts (1 gallon) of AGRI-AFC 15-0-15 and it weighed 6 lbs. 14 oz. Therefore, it is a “Course Grain Fertilizer” per the chart below.
When running in 1st gear High (1H)
2/21/2024 – Changed how I was calculating this adjusting the RPM to achieve the MPH rates in the chart rather than adjusting the rates to match the high RPM speed.
Tested Fergie’s run time in the Pecan Orchard between 5 trees (200) feet. Running in 1H gear at 2100 RPM she covered the 200 ft. in about 34 seconds which is 3 MPH. That is a good speed for the yard and small pasture.
At 3 MPH with the gate set on 2, it spreads 88 lbs/ac = 2 lbs/ksf. With the gate set on 3, it spreads 206 lbs/ac = 4.7 lbs/ksf.
