RotaDairon RX Stone Buriers

By , October 20, 2017 9:24 am


Stones, clods, grass and debris present major problems when constructing or renovating sports fields and recreation areas or preparing ground for turf production. Quality and safety of all sports surfaces from golf fairways to sports fields are affected by surface stones. Germination rates and levelness of ground are also affected by clods and organic trash. The Dairon Company, in association with members of the golf and turf industry, has developed a wide range of machines which bury all debris to leave a surface free of stones, clods, and trash:

SINGLE DRIVE : RX 130 & RX 180
DOUBLE DRIVE : RX 220 – RX 250 – RX 300

The roller frame supports the rotor by means of two depth control screw jacks. The reverse rotation rotor is equipped with special non panning blades which throw all the soil and stones against the selection grate. The stones, clods and debris land at the bottom grate of the cultivated dept to be covered with a blanket of fine soil 2 to 4 inches (5 to 10 cm) deep. The finishing roller packs and levels the soil surface ready for perfect seeding or sodding.

RotaDairon Factory Visit

By , May 8, 2017 10:49 am

A few of the team here at TGG have just returned from a visit from the RotaDairon factory in France. Although it was raining, it did not dampen our spirits we had a fantastic time. When you enter the building the first thing you see is the very first Dairon machine to be made, a reminder of how much history this family business is steeped in.

The factory set in stunning grounds in the middle of the race track at Mulsanne has always been in poll position when it comes to quality. The passion and innovation of Michele Dairon the Owner is – as ever – clear to see in every aspect of the business. He knows absolutely every detail of what goes on within those walls and he shows no signs of slowing down anytime soon. He is very much stuck in with the day to day problem solving and creating ideas for the next generation of Dairon machines.

The detail that goes into manufacture is immense, these machines are not just knocked together to make a quick buck. Every single element is thought through in great depth and detail resulting in the fine quality machines that RotaDairon produce today.

The factory is immaculately kept and currently in full swing production working through the mass of orders they have coming through the doors.

From design to production it is clearly a happy place to be. The excitement and passion of Michele was clear to see during our tour of the factory. Every chance he got he was on a machine to demonstrate the processes behind many of the parts that make up the Dairon machines, he literally lives and breathes his business. He and the team there are busy continually generating new ideas and developing processes to ensure the customer gets the best result possible.

Purchasing a Dairon machine is an investment, without a shadow of a doubt the best money you will spend. Whether you are looking for a self-propelled Seeder, a Stoneburier (various options available), an Overseeder or a Stabilizer – Dairon is 100% the product for you.

Springtime Scarification

By , March 14, 2016 10:07 am

Coming out of this year’s long wet winter, there is now an ideal window of opportunity to boost turf health once growth gets underway this year. Well timed scarification can encourage healthy growth, tackle disease and make the turf less susceptible to attack by pests. Greenkeepers and groundsmen can also save on chemical and fertiliser costs through these practices.









By getting  into the turf with a scarifier in the spring and take out the dead areas and moss that has grown, the fresh cleaned-up  turf will then make overseeding more effective, and ensure that fertiliser and top dressing can get into the sward. New growth can then infill as the season progresses, making for a harder-wearing, more resilient sward. A clean sward makes the best use of nutrients, water and air throughout the growing season. Scarification can have a dramatic effect on turf at a key time of year as air gets into the plant, stimulating vigorous growth.” Thatch can also harbour pests such as wireworms and chafer grub eggs, whereas strong spring growth means they have nowhere to go so making best use of fertiliser, and minimising the need for pesticides not only helps cut costs, but is also better for the environment, Selecting the right machinery as always depends on the area to be treated and the amount of material to be removed. For greens and tees, light and compact machinery is needed to protect the fine turf. The ATT TMSystem offers the ideal opportunity to make the most of machinery – greenkeepers who have the cutting units can quickly and easily swap for a scarifying reel. The options range from the pedestrian INFiNisystem unit which is the ultimate lightweight turf maintenance unit, to cassettes for greens triples and fairway mowers.








Tractor mounted options for greens and tees include the Rotadairon ED130 dethatcher from the renowned range of maintenance equipment, which also offers the versatility of use as a spiker. The ED130 can work to 60mm deep, rapidly clearing out dead material into an optional collector.The industry is being encouraged to move away from quick fixes and expensive potentially damaging chemicals and make a return to good regular methods and clearing out the turf in the spring is an excellent example of this.

Why choose a RotaDairon Stone Burier / Soil Renovator for your budget?

By , February 4, 2016 4:07 pm

There are now many brands of stone burier machines available on the market today but the RotaDairon is the original reverse tillage machine specifically designed and constructed to tackle all types of soil and achieve a quality seedbed in one pass.The machine works in a reverse tillage operation, the stones, clods, old turf and debris are centrifugally separated out and thrown to the bottom of the soil profile. A screen at the back of the machine gradually releases the renovated material with the finest soil at the top, this then passes under the levelling bar, seeding unit (if attached) and mesh roller.Favoured by many golf course, turf growers and landscaping professionals these high quality, rugged machines cultivate and renovate the soil, burying stones and debris providing the perfect finish for quality grass seeding results.









Designed to minimise damage to soil structure and compaction problems these machines will truly achieve optimum seedbed conditions.RotaDairon machines are built to last with specially designed rotors, blades, heavy duty construction and legendary reliability. Precision seeder attachments also enable us to cultivate, stone bury, level, roll and seed in one pass. This translates into a more efficient and cost effective machine that will give years of reliable service. For further details about the range available, contact us.


Cricket Renovation

By , August 17, 2015 9:07 am

As we near the end of the cricket season it is important to look forward to cricket pitch renovation. It is necessary to perform such a task very shortly after the last match so as to prevent the square from looking too sparse and to allow optimum regrowth before the next season.

Here at The Grass Group we have compiled some suggestions for renovating your pitch.


If you are looking for a complete renovation fraise mowing may be necessary.

The GKB Combinator is an apt machine for such a task, removing the top layer of grass and thatch accumulation.

For a slightly lighter approach, you can use the tractor drawn ED130 which uses its brush to collect as it scarifies. Alternatively, aggressively brushing the pitch to remove soil and debris can begin the process of renovation.



Aerification of the soil in a linear vertical, horizontal and diagonal fashion is optimal. Lots of smaller little holes tend to provide the best results. It may be necessary to flood the pitch several times in order for the ground to be soft enough for a sarel spiked roller. Our ATT TMSystem range has a sarel spiked roller perfect for the job at hand! If you use a different type of aerator, CTI tines could be complementary.


Next comes the OverSeeder. The small holes made during aerification have prepared the soil for the even deep spreading of the seed.

If there are particular areas that have been affected then applying a light coating of loam would be beneficial. OverSeeding can be done on a larger scale using the RGD140 or on a   smaller scale with the Seed Car.



As always, there are many different ways to renovate a cricket pitch and it is dependent on your preferences, pitch and weather conditions.

The toughest time of the year

By , February 9, 2015 9:13 am

For most Winter sports and golf,  the winter months are the toughest time for pitches and trying to keep the impact of wet, frozen and other harsh conditions to a minimum is a balancing act with teams needing and wanting to play whenever they can Saturated turf can lose strength and become slippery and grass cover can easily be lost. The physical properties of your soils will dictate how well your pitch can drain; sandy soils drain well, whereas heavier clay soils tend to be slower draining and even hold water.









The skill of a Groundsman especially on a tight budget is challenged at this time of year and all the pre work you have done throughout the other seasons will now come into play it is the work you do in the spring (renovations), and subsequent summer maintenance (regular mowing) and autumn (aeration) work, that prepares your surface for the winter.When ground conditions are reasonable, try and get some air back into the soil profile; this will help improve gaseous exchanges and help water drain from the surface.Mowing heights may vary depending on local conditions, type of course, course expectations, sward type and mower type. Soil temperatures should soon begin to rise towards the end of February/early March, enabling the grass plant to start to recover and speed up growth. From then on drainage should be less of an issue and spring plans can be put into action.












December and January turf maintenance

By , December 22, 2014 10:19 am

As the weather finally changes, Frost holes may be required on some greens in the morning as this will provide protection against any inappropriate wear. Don’t forget to slit tine aerate on a regular basis and keep your aeration programme working. Over the festive period maintain the greens height in accordance with course standards using your ATT Cassettes. This will usually be no higher than 8mm. If you haven’t already finished topping the fairways, this will most likely be the last occasion for a few months before you give your Progressive mower its winter service. Keep up the ongoing battle to remove leaves on a regular basis using your Trilo machine to prevent the turf being smothered.






For Bowling Greens earthworms may now be a problem so drag brush daily. Aerate to keep the surface open and to improve surface drainage and drying. This may also help to reduce the effects of earthworm activity.Look out for Fusarium patch disease during mild damp spells. Sulphate of iron applications can help to reduce the chance of disease attack. Sulphate of iron can help to harden the grass against this disease. Keep the grass topped at about 10mm to 12mm high as this will reduce the chance of disease attack. For Football and rugby, divoting is a key task at this time of year as growth is very slow. Repairs need to be made in order to maintain a reasonable surface for as long as possible. A regular brush and/or harrow if conditions are suitable will help to protect your surface. Overmarking should not be neglected. In order to determine a suitable overmarking programme, consider the weather conditions and how many games have been played especially with the extra matches across the Christmas period.Slit tine aerate the pitch but be prepared to stop if conditions are found to be unsuitable, you can cause more harm by continuing and also don’t forget to sand worn areas as required and overseed as required after matches using the RotaDairon SeedCar.


The last thing to remember is to enjoy a few days off and have a happy Christmas from all the team at The Grass Group.
