GKB Vstrong impresses again: Based in Woolpit, Suffolk and with over 35 years of experience and knowledge, Parkers Pitches added a GKB Vstrong to their range of robust and dynamic machinery, through GKB’s distributor Ernest Doe.

Parkers Pitches have a passion for sports pitches and knew the perfect partner to support their passion was the GKB Vstrong. The sports turf management company, run by hands-on Owner Will Parker, have been impressed with the performance of the machine so far, stating: “We pushed the machine very hard this Autumn renovation season with over 40 cricket square scarified in 3 directions.“

The beating heart of the machine is the CombiRotor, with its generically developed 3mm carbide scarifying blades. “The heavy duty nature of this machine has meant this year we have managed to scarify deeper and with closer blade spacings than in previous years, due to this we have seen great results with superb germination and coverage at all pitches renovated” Will adds. Thanks to the blades being rigidly attached to the rotor, the GKB Vstrong allows you to easily attain an operating depth of 5cm, not to mention it has a working speed of up to 10 kph.

Always completing high-quality work to improve and maintain surfaces and pitches the GKB Vstrong was a perfect match. Will explains “With the great results seen from a machine that is faster and cleaner than any we have previously used, we are in no doubt the Vstrong is the best machine on the market for cricket renovations and many other tasks.”

By scarifying and letting the material fly when you collect afterwards with a vacuum or a cut and collect mower, you are collecting less material. This leaves the soil behind and just takes the green waste off the top.

New SCAG stand-on mower

/in , /by

New SCAG stand-on mower: The V-Ride is a stand-on mower designed for professional use; the compact machine size, ease of manouevering and clear view for the operator have lead to the V-Ride becoming increasingly popular for intricate mowing areas. 

The Ride-On SCAG machines, because they are purpose-built for grasscutting, place the operator directly above the cutting deck, and one of the main features on the new V-Ride is that the revised configuration of the stand-on deck follows the same concept, placing the operator nearer the centre of the machine. 

New SCAG stand-on mower

The new version of the original V-Ride was announced in 2017 and had revised features that exhibit SCAG’s policy of continuous improvement and response to operator feedback, which combine to make them such a successful machinery manufacturer. 

The latest machine in the range addresses the need for gate-access: the V-Ride 32. 

The full model name is the V-Ride 32A-16FX: 

  • 32” Advantage Deck
  • 16HP Kawasaki FX
  • Electric start
  • Drive wheels: 20x6.5 – 10 
  • Fuel capacity: 4 gallons
  • New style 2020 V-Ride operator pad
  • All other features as on the 36” V-Ride

Case for the defence

/in /by

Case for the defence: The Christmas and New Year festivities are now just a lingering memory but though the days are starting to lengthen, there’s a long way to go before the onset of warmer weather.

With the turf suffering from prolonged periods of wet weather, waterlogged and weakened roots, the grass will be stressed and more open to disease attack. Deciding on which fungicide to defend your turf territory is key to ensuring a successful outcome. For winter applications, the requirement is to identify fungicides that contain ‘actives’ which work well under cool and cold conditions and, where possible, provide added physiological benefits.

Case for the defence

Particularly effective under cool, cold conditions is the broad spectrum turf fungicide Eland and applications now will provide disease protection for up to 50 days.

This long term protection is achieved through the spray deposit being held on the leaf long enough to penetrate and be held within the leaf tissue, which serves as a fungicide reservoir constantly releasing its active ingredient, pyraclostrobin, to provide long term protection.

Eland is specially suited to being applied as a preventative treatment, especially when disease pressure is high. It is very effective against all stages of the fungus within minutes of being applied and can restrain mycelial growth to provide additional curative activity.

Case for the defence

In addition to its proven abilities as a turf fungicide, research has shown Eland to have a number of additional physiological benefits.

Such benefits include improving plant health in the form of stress management under cold conditions and during aerification. This has the effect of helping the plant and root system to endure a stressful event and overcome stress through root system retention.

In addition to combating Microdochium Patch attack, a major benefit during early winter months is that applications of pyraclostrobin allows a plant to recover more quickly from root damage or surface foliar damage caused by ball mark injury.

Of course, prevention is always preferable and more effective than reacting after the event. STRI research trials prove that preventative disease control programmes outperform curative options when analysed for turf quality, colour and presence of Microdochium Patch (right).

The eight months trial compared nine preventative and three curative programmes, as well as one untreated plot. The first three programmes used purely preventative fungicides from Bayer. The rest of the preventative plots used a combination of Rigby Taylor fungicides, together as tank mixes with plant health products to reflect a more realistic approach. See bar chart, below right.

Case for the defence

In general, preventative programmes five to seven (see graph RT prog’s 1, 2 and 3) showed the most consistent results across turf colour, quality and Microdochium Patch presence by using an integrated approach with both fungicides and plant health products. The fungicides within the curative programmes (11 -13) were applied as and when disease developed to an unacceptable level, mimicking traditional control strategies. It is important to note that none of the trial plots had any cultural controls or biological practices applied prior to or during the trial, other than mowing and switching, which was carried out when necessary.

Pre-planning and control are essential requirements as it may be necessary to integrate some of the aforementioned products into the winter programme, which will enable the plant to resist or repel disease attack and be in an ideal state to advance into the spring in a healthy state.

Revolution in professional turf care

/in /by

Revolution in professional turf care: Strained sports turf surfaces are particularly stressed by the influence of walking on, playing on or driving on, which can lead to a change in the physical or chemical properties of the soil due to compaction. 

Compaction has negative effects on the vital growth of a healthy and durable grass population as well as on the functional safety due to the often highly reduced air and water permeability of the soil, a lack of water and nutrients available to plants, poor regeneration growth and changes in soil organic structure.

Revolution in professional turf care

The remedy can be found with the airter light 14160 – pneumatic soil aeration device for professionals, which loosens the lawn root zone homogeneously into a depth of 22 cm and supplies it with fresh oxygen.

This is done by steplessly adjustable compressed air in a continuous process. A football field can be completely processed in seven hours.

A total of 14 specially developed compressed air injection lances with triple jets push up to one million litres of air per pitch into the ground in an efficient working process.

The airter aerates the root zone homogeneously and with full coverage without any significant visible damage to the top surface. The penetration depth can be selected to match local soil conditions by using different lances so the soil compaction can be reduced up to 30% (verifiably tested). As a result, water flow and air circulation improve remarkably. Novokraft’s airsoftroll roller technology guarantees low ground pressure during sustainable aeration of the root zone with oxygen! Unique and unrivalled!

Advantages at a glance

• Effective and sustainable aeration of hybrid, sports and golf surfaces.
• Reduction of pesticide use and prevention of black layer through active ventilation. Efficient and biological pest control (e.g. larvae & grubs).
• Improved water absorption/storage within the root zone enabling shorter irrigation cycles and reduced water consumption, especially during the vegetation and heat periods.
• A measurable, homogeneous de-compaction of about 30% in the treated root zone layer.
• Reduction of downtime (no need for post-processing work, play areas can be walked on and played on directly, less waterlogging due to improved separating effect).
• Reduction of maintenance time (reduction of traditional aeration intervals and top-dressing needs, lower patch work and over-seeding requirements).
• Low maintenance cost (simple pneumatic/hydraulic system).
• Scientifically validated system (STRI in the UK and University of Hohenheim in Germany).
• Efficient operation (continuous operation, simple machine operation, high productivity).

The airter can demonstrably loosen the hardened hybrid turf systems. In all hybrid turf systems, the root zone cannot be optimally and professionally ventilated using conventional mechanical loosening methods (e.g. deep loosening with solid chisels).

Over time, these procedures inevitably lead to vertical compaction of the lawn base layer.

Novokraft has developed the airter to solve this problem and to professionally loosen the root zone. This prevents the formation of decomposition gases, which are toxic for lawn roots.

Practical tests on new hybrid turf fields have shown that with the loosening effect of the airter, the players subsequently felt the fields to be much softer.

Likewise, this homogeneous pneumatic loosening method massively improves all bioactivity in the soil. The airter is also ideally suited for the reliable maintenance of water permeability.

Prevention better than cure

/in /by

Prevention better than cure: Ian Robson Prosport UK & Ireland Importer/Distributor for Foley United, explains why relief grinding maximises the performance of reels by giving a factory finish every time.

Firstly, why is having sharp cylinders (reels) that are the correct shape so important anyway? The answer is obvious – unhealthy turf brings a whole host of other issues which are costly to correct. Therefore, prevention is a far more economic approach than a cure.

Prevention better than cure

A huge amount of research and development has gone into designing a cutting unit to produce the cleanest cut possible with the least amount of fraying and tissue damage to the plant.

The result is that all manufacturers of grass cutting equipment supply new units with relief ground edges.

Why Relief Grind?

Tests carried out by leading manufacturers have established that relief ground cylinders stay on cut up to three times longer than spun ground ones and require less horse power to drive the unit, resulting in greater fuel efficiency and less stress on the hydraulic power systems. In addition, a relief ground cylinder will withstand the abrasive effects of top dressing far better than one spun ground because the relief edge on both the bedknife and the cylinder allows the top dressing to clear the cutting blades easily, helping to prevent the dulling effect seen on spun only units.

Continual relief grinding also decreases the squeezing and tearing of the grass as the units get dull, and most importantly it allows the cylinder to be returned to a factory specification perfect cylinder as quickly as possible.

The overall cleaner cut achieved by relief grinding gives a better after-cut appearance, increased recovery rate due to the clean cut of the grass and reduces the stress on components because less horsepower is needed to drive the cylinder.

Horse Power Study

As a reel wears flat and loses shape (becomes coned), more stress and strain is put on the cutting systems.

Using the figures from the above study a 5-gang cutting unit with relief can require up to 4.5 HP (5 x 0.88HP = 4.5HP) to drive the cutting units therefore a 35HP engine has 30.5HP remaining to drive the rest of the traction system. A 5-gang unit which has been spun ground only, can require up to 13Hp (5 x 2.59HP = 13HP) leaving only 22HP to drive the rest of the traction system.

So, it has been established that relief grinding your cutting units saves you money not only by reducing workshop maintenance time with far fewer grinds but also through a reduction in fuel costs and replacement parts.

It is also important to acknowledge what relief grinding does for a reel. By removing metal from the trailing edge of the blade it forms a relief angle, which reduces the contact area of the cutting edges, resulting in less friction, longer wear life. Typically, when a new mower is delivered the reels will be a perfect cylindrical shape. Over time the blade naturally loses shape, and the sharp edge it arrives with becomes flat and dull, often meaning the reel is no longer a perfect cylinder from end to end. This is referred to as ‘coning’ and a natural point for grinding to take place.

The decision then sits between touch-up and spin grinding, or relief grinding. If there is sufficient relief still on the reel then a quick touch-up is fine but once more than 50% of the relief has gone my advice would be to relief grind again and remove any coning. Failure to remove the coning will eventually be seen in an uneven cut appearance of your turf.

But, the main question mentioned at the beginning comes back; how to get the most out of your workshop resources by choosing the most effective method to sharpen your cutting units. The answer is to trust the manufacturers judgement and return the reels as close to the original factory standard as possible, and for that, relief grinding is the best option. The bonus is this method also maximises performance and gives the best cut.
