Pitch renovation

By Grassgroup, May 7, 2015 3:01 pm










As well as these tasks you will also need to at some stage to think about weed control.  At some stage you will need to consider where your weed killing programme fits into the picture of your pitch renovations.

If the list above is taken as a sequence of events, then you won’t go far wrong with your renovation, though you may need to give some further attention to goal mouth and centre spot areas which will be covered later.

Scarifying: however you achieve it, you will need to clean out the surface, removing the remnants of old divots etc. and to get rid of the build-up of dead organic matter accumulated over the winter months. Thatch can build up particularly on the wings of the pitch, away from the more intensively played areas in the centre and goal mouth areas. Before carrying out this task you will need to reduce the height of cut. This will not only help your grass to establish better, but will help your machinery to carry out the work without struggling the TM System from ATT fitted with Thatchmaster cassettes can give you a really good finish and remove matter without too much disturbance.






A tractor drawn Trilo scarifier with either a three point linkage or a large vacuum collection model, are probably the most traditional methods, and most likely within the means of most clubs and schools, allowing the job to be completed in one operation. This method can be advantageous as the scarifying tines can leave a grooved surface, ideal for ensuring over sown grass seed is buried just beneath the soil surface and in contact with the soil. Whichever method you use, you will be aiming to achieve a surface that is short and clean with a finished mown height of 13mm to 20mm that will give your grass seedlings time to grow and establish without competing too much from the existing grasses.

Fraise Mowing with the GKB Combinator is an operation that is becoming popular to those that can afford it (mostly Premiership clubs fall into this bracket). Topping is extremely efficient at removing the top organic layer of the pitch however; you will effectively be starting again with a newly sown surface so your seeding rates will need to be higher.







Relieving compaction is important, and spiking as deeply as possible is required. There are several ways this can be achieved and to a depth of 250 – 300mm. Pay particular attention to your goalmouth and centre spot areas, and don’t forget too the off pitch areas where your linesmen and spectators stand.

Fertilising: A good pre-seeding fertiliser, typically one low in nitrogen and high in phosphorus and potash, will provide the young seedling with the essential nutrients to root quickly and to resist disease. This should be worked into the surface, brushed or drag matted in. Water in if rain is not expected.

Seeding: Obtain a good quality rye grass seed mixture for your renovation. Fresh seed is important as old seed will not germinate as greatly or as well as new. Look at the STRI list for the range of recommended cultivars, listed by fineness of cut, resistance to disease etc. and choose a mixture with the characteristics suited to your needs and situation.

The roller can be lowered on the final run to firm the surface and ensure good soil to seed contact. Alternatively the use of seed drills will help to bury the seed into the surface and at a depth where it won’t be subject to drying out. This method will produce a linear seeding pattern and it is best to complete two passes or more at a slight angle to the first.

Topdressing: Chosen wisely for compatibility with your current root zone is an essential ingredient to ensuring good surface levels. If you employ the services of an agronomist then he will have advised you of the best topdressing for your situation. This may typically have been a medium to fine sand and of a quantity of 60 to 80 tons per pitch.

Low areas in the pitch can be concentrated on. Minor dips and hollows that collect water, noted during the winter, can be further spiked. A slightly heavier topdressing spread than the surrounding area will help to raise these areas, though be careful to ensure the topdressing is worked into the holes and into the base of the sward. The topdressing should not be thick and left covering the top of the grass, as this will only lead to a weakened sward. Repeat the operation if necessary and check it with a straight edge.

Goalmouth and centre spot areas: At this time of year how much grass is still around in these areas depends on a number of factors, and is a combination of the condition of the sward at the start of the season, number of games played, the conditions that they were played in and finally the adopted post match and winter maintenance regimes. Suffice to say that the wear can range from minimal with some pitches sustaining little loss of grass in the goalmouth area to an area or strip if you like running the whole length of the pitch completely devoid of grass cover.

Some goalmouth areas may even have lost both grass cover and soil, where the soil has migrated out of the area. In these areas it is important that they receive more concentrated effort to relieve compaction and to bring the surface levels back, by importing and incorporating new material compatible to your native soil or by using something like the GKB Cultirol to break up and level the soil.

Summer Scarifying

By Grassgroup, June 13, 2014 10:27 am

The importance of scarifying during the summer is vital for the health of your grass. If you keep the plant in good health and take the dead material out by scarifying the water and fertiliser will get to where you want it to therefore improving the condition of your playing surface.

The removal of thatch also ensures air gets into the sward, enhancing the plants natural defenses against disease. The Rotadairon ED130 TS de-thatcher that can work to a depth of 60mm, or a machine such as the Trilo VCU scarifier can rapidly clear out dead material. Some fairways can produce as much as 20cu.m of dead material so a scarifier collector from the Trilo range might be the answer.

Trilo in Orlando

By Grassgroup, February 22, 2011 2:18 pm


I have been involved with Trilo for over 20 years and have sold over 1000 machines.  I have also been closely involved with the factory in the initial sales and distribution of machines on the West Coast of the USA.  So it was good to see Peter van Mispelaar, whose company ,Vanmac,  now produces Trilo, at the Golf Show in Orlando with an SG300 vacuum sweeper, BL960 and the full range of VCU scarifiers.  The Trilo range is distributed in the USA by STEC Equipment of South Carolina.

As in Europe the vacuum sweepers and scarifiers are used for grass cuttings, leaves and litter but also on US golf courses they are used when the summer grasses go dormant.  The greenkeepers scarify the fairways heavily prior to over seeding with temperate grasses which will remain green throughout the winter.  The heavy scarifying removes huge amounts of material and all the fairways have to be done in a very short period making the Trilo with its awesome power and cavernous capacity invaluable. As the warm season grasses start growing again in the Spring they compete out the finer temperate species and the whole cycle starts again.

As well as having machines on courses such as Augusta National and Jupiter Hills,    Trilos are also used on US sod farms and by the worlds largest refuse company, Waste Management.

Scarifier extends The Grass Group’s professional machinery line

By Grassgroup, March 29, 2010 3:15 pm

The Grass Group presents an exciting new product from renowned turf machinery manufacturer Trilo at BTME.


Greenkeepers are well aware of the benefits of scarification on fine turf, where it removes thatch and tidies up unwanted lateral growth.  The operation encourages healthy growth and maintains the appearance of greens and tees throughout a busy playing season.

 The process also improves surface penetration by water and enhances airflow around the plant which minimises the potential for disease.

 Finding the right machine can be tricky – pedestrian scarifiers make it a time consuming job and can suffer from wear and tear with a heavy workload. On fine turf, tractor mounted machines can be heavy and cumbersome.

 Trilo’s new VCU 120, however, has a working width of 1.2m – ideal for greens and tees – and weighs in at just 225kg, teaming up ideally with compact tractors. A slightly offset design allows working right up to the edge of the green or tee without risking damage by the tyres.

 Spacing for the rugged tungsten tipped blades is 50mm as standard, but can be swapped to 25mm for greater intensity and working depth is to a maximum of 50mm, for effective, clean scarification that will be an asset on any golf course.

 The Grass Group’s Progressive Pro Flex 120 rotary contour mower is another winner for golf. Ideal for producing a fine finish on fairways and surrounds without the risk of scalping, the Pro Flex 120 shares its PTO shaft, running gear, blade spindle assembly and drivetrain with the renowned Tri-Deck Series.

 With a high blade tip speed for a top quality cut, the mower decks are equipped with shock absorbers to prevent the deck bouncing and allow cutting as speeds up to 10kph. The full frame design allows cutting to continue while reversing, further boosting productivity.

  Individual decks hug ground contours, floating fore and aft as well as side to side, giving a superb cut on the most undulating course. Outer wings fold for transport, and with the two exterior decks raised, the remaining three can continue to cut, allowing more restricted areas to be maintained.

 A great finish is assured by the use of adjustable discharge deflectors for an even spread of clippings.

 Cut width is 3m for high workrates, reducing to 2.44m in transit and cut height is easily adjusted to meet requirements from 2cm to 8.25cm.

 The Grass Group continues to focus on innovative new machinery to make the greenkeeper’s life easier.
