Moore Unidrill’s Guide to the Ultimate Grassland Overseeder? We’ll forgive you for thinking this article might be a publicity stunt written by a company who have been specializing in the field for forty years 😉. Believe you me, it isn’t…well not entirely.
The reality of the matter is that we all know there are a good number of alternatives out there; we’ve learnt this firsthand from our dealings as a family over a long period of time in the used machinery industry. We could reel off the qualities of a Moore Unidrill once again, but below we’ve decided to name all its contemporaries and offer you useful and informative comparisons. At the end of the day, that’s the information you’re after…
Why Use An Overseeder?
If you’re an agronomist, agriculturalist or livestock farmer, optimum pasture and grassland quality is a priority. Use of a grassland overseeder ensures improved seed-to-soil contact, placing seeds directly into the soil at the correct depth, ensuring higher germination rates over against traditional broadcasting methods. This regenerative farming method will result in a higher percentage of the seed applied establishing themselves as healthy plants, leading to a denser crop, healthier root systems, better nutrient uptake and overall productivity. Where traditional tillage methods may lead to soil erosion, nutrient loss and poor soil structure, an overseeder increases soil health, leaving beneficial microorganisms intact and protecting the environment. In addition, overseeding is a cost and time-efficient method, needing only one pass for successful pasture establishment. Finally, using an overseeder also enables farmers to introduce new and improved grass varieties into an existing pasture, which is key for consistent forage supply and the health and productivity of the pasture and livestock.
What Are The Overseeder Options?
For this article, we’ve summarized the key features of several machines currently on offer in the overseeder market. Read on to find out more…
3 metres – 12 metres
Tine or Disc Drill?
The PNEUMATICSTAR is designed for grassland care, seeding, overseeding and reseeding. The seeding roller is driven mechanically via a support wheel or is electronically controlled by different sensors. The machine has a strong frame, and depending on the working width, the frame is either rigid, mechanical or hydraulic folding. The machine’s high-quality construction means that the user can put additional pressure on the six rows of tines in hard soil conditions. There are 2 versions of the PNEUMATICSTAR available; The MD Version has a mechanically driven seeding roller and the STI version has an electronically driven seeding roller, controlled by the STI terminal. The machine has a narrow row spacing of 2.5cm/1”.
Tine or Disc Drill?
£12,923 – £44,215+
This 5-in-1 machine designed for small-medium pasture regeneration aims to level, aerate, weed, sow and re-consolidate in one pass. The 12mm robust double spring tines act to aerate the soil, and seed is subsequently delivered via tubes on the back of the tines resulting in consistent successful germination, especially in initial seeding. Following the seed delivery, the self-cleaning Guttler prism rollers act to press the seed into the soil as a cloven hoof might do.
Model Name: AIR8, AIR16, AIR16E PRO, AIR8E
Working Widths: Up to 24m
Tine or Disc Drill?
£5950 (without seeder unit) £11250 (with seeder unit)
Opico’s offering is designed to accurately meter and distribute grass and small seeds evenly across the full width of the grass harrow which opens the soil, creating a tilth for improved seed to soil contact. These machines are usually fitted to an Opico grass harrow, but will also work with grass harrows from other manufacturers. The seed roller metering is driven by a land wheel on the AIR 8 and by electronic radar on the AIR 8E and AIR 16E. The 8 outlet seeders have an electric fan whilst the 16 outlet seeders have a hydraulic fan. The grass seeder seed rate can be varied from 1-80kg per hectare, according to seed type and whether the user is reseeding or overseeding. Where overseeding only specific areas of a field, electronic seeders can also be switched on or off during the harrowing operation.
Model Name: Vredo Agri Series
Working Widths: 2.47-2.85m
Tine or disc drill?
Price Ranges: £26,000 approx
The Vredo Agri Series on the market today has evolved from the original conception of the machine in 1976, with a great number of developments and improvements on the machine since. The machine operates a highly accurate mechanical seed distribution system with progressive spring guards. This is a robust machine that comes highly recommended for dairy farmers and agricultural contractors.
Model Name: Moore Unidrill Grassland Trailed/Mounted Models
Working Widths: 2.5m-3.4m
Tine or disc drill?
Price Ranges: £26,775-£38,115
This is a direct disc drill machine designed with a professional contractor in mind. Moore Unidrill have over 40 years in the direct drilling and overseeding market, making their offering a reliable and trustworthy one. Simplicity in terms of its construction alongside a high quality of machine components has resulted in a machine that will have a long working life with low operating costs. The machine uses an accord metering system, allowing the ability to sow down to the last quantity of seed with most seed types. As well as this, the machine uses a rubber arm suspension system for optimum contour following on uneven ground. This machine is available in trailed or mounted options at varying widths as well as a ‘base unit’ option (not included in the price range shown above), which may offer a considerably cheaper option for a user who wants to use the machine with an existing hopper.
Model Name: Erth Agriseeder
Working Widths: 3-4 metres
Tine or disc drill?
Price Ranges: £23,000+
This machine is a direct disc drill that allows the coulter system to move independently on rubbers and has a secondary ‘autocontour’ system to follow undulating ground. Each frame section has its own hydraulic ram, allowing pressure to be balanced across the machine along rough ground, reducing load on wearing parts and bearings and achieving better seeding depth. Keen-eyed buyers will note that this machine uses the Kverneland Accord metering system also found in the Moore Unidrills. The machine is available in three or four metre widths with 24 or 32 rows. Buyers can opt for a hydraulic fan, twin or single electric fan or an electric metering system. This simple machine is a good match for small applications and lower horsepower tractors.
To conclude, we hope you have found this guide a useful source of information in view of your purchase of an overseeder. When it comes to the best option, we advise you look carefully at the application for your overseeder; what works for one farmer may not for another. Remember that climate, soil conditions and acreage vary from farm to farm.
For overseeding, a disc drill would certainly be our personal recommendation based on our experience in the farming industry. Overseeding is by nature a regenerative farming method, as little soil disturbance as possible is the desired effect, and the harrowing action of a tine drill will be counterproductive. What’s more, removed weeds, soil and seeds will clog tines and/or rollers. A disc drill creates a narrow slot through existing crop residue that allows the machine to stitch in seeds, with minimal disturbance and preservation of soil health. Though tine drills are considered to have better flexibility, all the disc drill options shown here have contour-following technology to counter this. In the case of the Moore Unidrill and also the Erth machines, high quality components are used to give the extra wearing parts that come with a disc machine a longer working life. Though this may result in a heavier machine, additional weight on a overseeder is often considered beneficial for better penetration.
