Introduction
This document explains the features of all SRES/Monosem planters and the specific features of the SRES modifications in each family series, the “Advanced” Series and the “Classic” Series. This comparison will help make it easier to decide which planter will be more compatible with your existing needs. The Classic series can be upgraded to include all of the features of the Advanced Series planter.
Accurate Seed Singulation
All SRES/Monosem planters are well-known for accurate seed singulation. Each planter utilizes the Monosem vacuum metering system, which holds the seed gently onto the holes of the seed disc. The flat surface of the heavy-duty stainless steel disc accepts a wide variety of seeds, regardless of size or shape, without loss of accuracy. The Monosem patented metering box contains a single adjustment lever that adjusts the height of the seed scraper and the vacuum pressure at the same time. The scraper aligns the seed to the hole and eliminates doubles and skips.
Accurate Seed Spacing
As the seed disc turns, a brass ejector block assures that the seed is dropped at a consistent angle, reducing seed bounce inside the tube and resulting in precision seed spacing every time.
Consistent Depth Control
The double disc openers are flanked by independent, large-depth gauge wheels that are engineered with an equalizing rocker bar. This assures uniform depth control, even in “cloddy” or rocky field conditions.
Good Seed-to-Soil Contact for Germination
The Monosem planter provides good seed-to-soil contact for superior seed germination in any soil condition. The popular V-press wheels are independently mounted and are adjustable for shallow, medium, or deep planting.

| All SRES planters are based on the Monosem NG Plus commercial planter or the Monosem MS mini-seed planter. The SRES Advanced Series, the Classic Series, the Monosem MS and the Twin Row planters all comprise a full line of planters and give researchers an excellent choice to address virtually ANY type of research planting need. | |

Advanced Series
Big John computerized control system |
Classic Series
One button programmable logic controls with variable settings |
| • Up to 9 preset populations, variable from plot to plot |
• Seed population is controlled by transmission sprockets and seed plate holes |
| • Pre-field set-up - most settings can be entered into the computer prior to going to the field - settings from prior operations can be saved in a data file and re-used |
• Planter settings are changed in the PLC in the field as needed |
| • Infinite seed spacing capability |
• Seed spacing is controlled by transmission sprockets and seed plate holes |
| • Setting for number of seeds to be planted in a given plot length, or by seeds per acre |
• Seed spacing is controlled by transmission sprockets and seed plate holes |
| • Display showing seed drop, no. of seeds being dropped, seed spacing, and alley display |
• A "Dickey John" display is optional - seed spacing is controlled by transmission sprockets and seed plate holes, alleys are determined by field marking |
| • The plot length is preset assuring consistent (non variable) row and alley length throughout the field - also assures cleaner alleys so trimming is not necessary |
• Alley lengths are affected by tractor speed, manual intervention and timing. Shorter alleys may be defined by slower speeds or stopping in the alleyway. In some cases, the alley may be one or two seeds off, requiring minimal trimming. Because plot lengths are controlled manually, they may be varied from plot to plot. Number of ranges is infinite |
| • Number of ranges to plant, is preset depending on field length and plot length (if data capture is required) |
| • Field mapping capability |
• Field mapping not applicable |
| • Built in help screens to assist operator to understand various functions |
• A decal has been applied to the PLC showing different settings and how they can be used. |
| Self-contained electrical system with alternator and battery (standard) |
Self-contained electrical system with alternator and battery (optional) |
| Vacuum chambers for collecting excess seed (standard) |
Vacuum chambers for collecting excess seed (manual or automatic) |
| Air compressor system may be used for additional functions other than the planter (standard) |
Air compressor system may be used for additional functions other than the planter (optional) |

More thoughts on choosing |
| The Advanced Series has full function and is fully programmable to allow for the needs of the researcher requiring more complex planting methods. This planter may be justified because there is no need for alley trimming, thus miminizing manual labor costs and time. Because shorter alleys are feasable without stopping or slowing down, it is ideal for putting in large numbers of plots in a short amount of time. While this planter is quite capable of planting rows of any length, it was designed for best efficiency with plot lengths in the 50 to 15 foot range. |
If initial cost and simplicity of operation is critical, the CLASSIC is a good choice because of "Upgrade-Ability" – low cost, comparable to a cone planter, but may be upgraded in steps. This planter is simpler to operate, while still possessing the accuracy and reliability of the "Advanced". The planter was also designed for planting lengths of zero (feet) to infinite plot length. Commercial hoppers may be used to plant small increases to production fields. |
