Tools for pruning radiata pine

If you have decided to prune, then use the right pruning equipment. The
two most common methods of pruning are with manual loppers and saws, or
a petrol-driven top-handled chainsaw. Most plantation forestry pruning
is still done using loppers. However, there has been an increase in the
use of top-handled chainsaws in recent years.
There are pros and cons for both methods, but generally pruning loppers
produce a better job. A branch that is pruned with a clean cut will
heal over faster and cleaner. Other advantages of using loppers and
handsaws is the low cost of buying and maintaining the equipment
compared to a chainsaw.
On the other hand, using a top-handled chainsaw usually means increased
productivity and less physical effort from the operator for each
pruning lift. Chainsaws can be expensive to buy, as can the necessary
safety gear, as well as the maintenance. Chainsaws are also noisy, and
the risk of branch collar damage is generally more of a problem.
Finally, there is a higher risk of injury associated with the use of a
chainsaw while perched on the top of a ladder up a tree. Extreme care
needs to be taken. It is important that you check the safety
requirements from information supplied by OSH.
Minimum equipment
The choice of equipment is a personal decision. If you decide to prune
using manual equipment, then the bare minimum in equipment that is
needed is –
- Forestry pruning lopper
- Forestry pruning saw
- Epicormic knife
- Holster to carry the above tools
- Ladders, generally a 2.4 metre ladder for your second prune and a
4.2
metre ladder for further prunes
For chainsaw pruning, as a bare minimum you will need –
- Top-handled chainsaw with a 250 mm to 300 mm bar
- Earmuffs grade 4 or 5
- Mesh goggles or a visor
- Chainsaw chaps
- Chain safety guard
- Belt hook to secure the chainsaw while manoeuvring up and down
the
ladder and between trees
- Fuel and oil containers
- Ladder
Other equipment includes safety boots, harnesses, safety lanyards and
hydration packs whether manual or chainsaw pruning.
It is strongly recommended that you learn the techniques of safe and
efficient pruning from an experienced pruner. This will markedly
improve your productivity.
Finally, make sure you contact or visit a specialist forestry equipment
supplier before you start pruning. Having the correct equipment for the
job will save a lot of time and anguish in the long run.
