but remember that they need a pit one and a half to two times the size of the root ball. They also require staking and the installation of an irrigation system. Trees can be supplied as two year old forestry transplants or as standards. The latter are larger initially but grow little for five or six years. Forestry transplants are 45-60cm tall but will grow relatively quickly. There is also the matter of price - forestry transplants are 20-30p each as opposed to £20-30 for a standard. Mycorrhizal root dips can be used before the transplant is placed in a tree tube, and we have seen extremely good results with them. Tree and hedgerow work cannot be undertaken during the nesting season from March to August but,
guard and chain brake. When the operator shuts down the throttle completely, the clutch automatically slows the chain drive and stops the chain running. If the operator pushes the finger guard forward, the chain is mechanically halted immediately. The guard must be re-set before the chain will move again. The new easy-start system
featured on the latest DCS3501 and DCS4301 models provides a spring assisted cord action, said to reduce the cord effort by 50%. Coupled with a new variable ignition timing and push fuel pump, the new easy-start system is designed to ensure efficient first time starting which eliminates the risk of operator strain or accidental machine movement whilst starting.
In operation, Makita’s 2- mass system effectively separates the grip handles from the body of the machine by mounting the handles on spring-fulcrums, designed to substantially reduce the transmission of vibration through the handles to the operator. For instance, the 50cc DCS5030 has tri-axial rating of 4.7m/sec2, reducing HAV risks.
battery powered saws offered by Pellenc and distributed by Etesia. With a power output equivalent to 30cc, the Selion Pole and Telescopic chainsaws are fitted with an Oregon chain for accurate cutting. With a lightweight design and +90°/- 45° angle adjustable head, the Selion Pole and Telescopic chainsaws allow vertical and horizontal cutting from the base of the tree. Pellenc chain guide bars are made from composite materials for torsional flexibility and to
Another approach is the
once the autumn work is finished, provides variety and motivation for greenkeepers through the hard winter months, so bringing the work ‘in house’ can have advantages which are more than just financial. While many greenkeepers will have chainsaw qualifications from their training and may have added further skills in climbing or large tree felling, a woodland management course can provide further tools for caring for golf course trees. STRI’s own course is dedicated to ecology, including woodland management, and comprises classroom training along with half a day at St Ives Golf Club, next to the Bingley headquarters, studying woodland on the course.
features a simple ‘click’ from the spring when the guide bar is fitted, providing assurance that both the guide bar and chain are correctly tensioned. The chain can be removed and installed easily using a retractable spanner integrated in the head of the tool. The retractable spanner is
In professional hands
also used when the chain needs re-tensioning during cutting. Electronic oil flow control is said to give a 30 percent saving on oil compared with a typical petrol- engine chainsaw. Benefits of the Ultra lithium battery are odour and pollution free operation and a high working capacity.
chainsaws weigh in at 2kg and less than 1.7kg (excluding battery packs) with a power output equivalent to 35cc and 30cc respectively. An Oregon chain, composite guide bar, automatic chain tensioning and electronic oil flow control also feature on these saws. The Selion C15 and M12 have a direct drive chain sprocket rather than a clutch and gearbox for efficiency and reduced weight. An electronically-triggered kickback sensor
instantaneously applies the electric chain brake in the event of a fall or kickback.
