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.

Voulez Vous Rota Dairon? Yes, says The Grass Group

By , March 29, 2010 3:49 pm

The Grass Group have been appointed by the French company RotaDairon as its sole UK importer.

The company’s portfolio encompasses soil renovators and stone buriers to prepare the ideal seed bed and create a fine soil surface.  Extra material, such as compost, fertiliser, sand, or fibres can be blended in, and seeding can also be accomplished with the addition of a seed box to the machine.  The rolling capacity completes the ‘one pass’ capability.

 RotaDairons’ turf seeding and turf care machines are the most comprehensive seeding and grass renovation products on the market – for not only primary seeding (construction), but also over-seeding, slit seeding, scarifying and de-thatching.  Versions are available as pushed or pulled handy seeders, as well as self-propelled seeders or 3 point hitch seeders for tractors.  Drop seeding is catered for in compact forms, and for wider applications a pneumatic air seeder completes the line up. 

 Tim Merrell, The Grass Group’s MD, is particularly pleased with the appointment as he started his career in France, “My early days as an Agronomist were spent on a farm in France where I first came across RotaDairon.  Their range of products fit very nicely within our existing portfolio and helps us to put together a complete range of equipments for the Turf Care professional.”

 RotaDairon’s products find applications in almost every turf care situation, including local authorities, landscapers, turf producers, sports grounds, golf courses and research centres.
