2.8 Dangers Due To Overhead Power Lines
There are significant dangers involved when working in the vicinity of Overhead Power Lines (OHPL’s). Be
aware that some Spearhead machines are capable of reaches in excess of 8 metres (26’) and have the potential
to well exceed; (by possibly 3 metres (9’ 9”); the lowest legal minimum height of 5.2 metres from the ground for
11,000 and 33,000 volt power lines, see Figure 2.1.
DANGER! All operators must read the following information and be aware of the risks and dangers
involved when working in the vicinity of Overhead Power Lines (OHPL’s).
WARNING! Fatal electrocution can occur without contacting a power line. Due to the high electrical
potential between the conductors and the ground a flash over can occur from the power line to
any conducting medium within range. Steel cutting machines are ideal conductors.
Wherever possible the safest option is always to avoid working in areas close to OHPL’s. Where unavoidable,
all operators must perform a risk assessment and implement a safe procedure and system of work, see Section
2.8.1 below.
All operators should perform a risk assessment before operating any reach arm mower within 10m horizontal
distance of any OHPL’s. If you are unsure do not work in the area. Never put yourself or others at risk.
2.8.1 Risk Assessment
Before starting to work near OHPL’s you should always assess the risks. The following points should be
observed;
•Know the risks of contacting OHPLs and the risk of flashover.
•Always find out the maximum reach height for your machine mounted on the tractor.
•Always find out the location and route of all Power Lines within the work area.
•Always find out the operating voltage of all Power Lines within the work area.
•Always contact the local Distribution Network Operator (DNO) who will be able to advise you
on the operating voltage, exclusion zones, the minimum safe working distance and any
additional precautions required.
•Never attempt to operate the machine within an exclusion zone.
•Always work with extreme caution and plan your work ahead to avoid high risk areas.
•If doubt exists do not work in the area –never risk the safety of yourself or others
Further information and leaflets on this and other agricultural safety subjects are available on the ‘Health &
Safety Executive’ website at the following address: www.hse.gov.uk/pubns/agindex.htm
2.8.2 Emergency Action for Accidents Involving Electricity
•Never touch an overhead line - even if it has been brought down by machinery, or has fallen.
Never assume lines are dead.
•When a machine is in contact with an overhead line, electrocution is possible if anyone touches
both the machine and the ground. Stay in the machine and lower any raised parts in contact or
drive the machine out of the lines if you can.
•If you need to get out to summon help or because of fire, jump out as far as you can without
touching any wires or the machine keep upright and away.
•Get the electricity company to disconnect the supply. Even if the line appears dead, do not
touch it - automatic switching may reconnect

2.10 Guarding
DANGER! For safe operation it is essential that that all guards must be kept in position on the machine
whenever the machine is running. Spearhead Machinery disclaim all responsibility for any
damage or injury arising as a result of guards being removed, or of guards other than of
Spearhead manufacture having been fitted, or of operation of the machine other than in
accordance with these instructions.
DANGER! When hedge cutting a mesh guard must be fitted to the side window of the tractor cab. Cabs
without laminated or toughened glass must also be fitted with a laminated glass or
polycarbonate shield in addition to the welded mesh guard.
WARNING! Inspect guards twice daily or immediately damage is suspected.
Always replace guards that have damage or wear which could impair their performance.
When using the machine on a loader frame or a forward reach reach arm, the machine attachment is in front and
above the driver’s cab. This makes it necessary to always work with guarding fixed around the front and side of
the cab, a typical installation is shown below.
Figure 2.6
A machine safety cover guard covers the knife cutting area and must be kept in position when the machine is not
operating or is being transported. They are an essential part of the machines guarding. The machine must not
be transported or stored with this cover guard missing.
The cutterbar assembly itself has two fixed safety guards to protect the machine whilst operating. Knife arm
guards are fitted in front of the knives in order to protect the machine from larger objects and to spread the soon
to be cut material evenly across the machine and draw it into the cutting area. Safety end fingers protect the
most outward blade from damage in a similar way. Both of these guards are an essential part of the machines
guarding. The machine must not be operated with these guards missing.
