Fall and winter seasons are good for trimming trees, such as, oak. Using an automated saw for it, saves time and physical efforts one would require to expend, manually.

Choosing the right time to trim trees in your garden is of great importance. A variety of trees are pruned and trimmed to maintain its neatness and increase the overall decor of the place. The most commonly trimmed ones are the Oak trees. Pruning an oak tree during April and July is as good as sending an invitation to sap beetles to infest it. This insect is a known carrier of oak wilt fungus which can infect a oak tree within no time. Naturally, Oak trees fights the fungus, but a freshly trimmed one is exposed to it at the site of cuts received during the process. Late winter and early spring is the right time to trim deciduous trees.

Trimming an oak tree is not an easy task and if you have planned it in near future, going through the equipment that you can buy or use, will be helpful. Among the automated equipment, chainsaws are the most versatile form of tools. When employed with climbing ropes and fastening harnesses they make your job easy.

Types of Saw
The decision of whether to use a small chainsaw or a large one depends on the scale of the job at hand. The type of chains used in the chainsaws depends on the hardness and thickness of the trees to trim.

• Gasoline-powered Saw: These chainsaws are most useful for regular use. However, these are noisy and best suited for working in areas in the open or where noise is not an issue.
• Electrical-powered Saw: The noise level is tolerable while working with these chainsaws. These are light in weight and don't pollute the environment. These are low maintenance, cheaper chainsaws that can be used for light-work, around the backyard. Before buying one of these saws go through some electric chainsaw reviews first and then decide which is most suitable for your needs.
• Pole Mounted Saw: Pole saws are necessary power tools for tree trimming close to the ground. A pole saw, as its name suggests, sits at one end of a metal pole and is essentially, small in size. It is raised to the desired height during a trimming operation by raising or lowering the metal pole. The height they can reach, can be increased by attaching an additional metal pole. These can be raised to the height of 13-21 feet. Pole trimmers are light in weight and easy to handle, and are one of the must have trimming tools for your garden.

Trimming Saws Used by Professionals
Chainsaws, used by professionals, have specially designed heavy-duty chains that can handle large amount of wood cutting work. They are also built to withstand the fast pace of the professional work. The term 'Kickback' is applied when the movement of the chain is obstructed and the chain starts moving in reverse direction. It is something that a novice to these chain can handle easily which highly increases the chances of his getting hurt. In short, leave this baby in care of experienced ones. Professional trimmers are trained to handle such situations. In addition, the instincts they acquire through the daily handling of this tool gives them the knack of using it with a deft hand. A task involving cutting down of trees, especially when they are big ones, can be handled in a better way with the use of these saws.

Consumer Saws for Trimming Trees
The chains in consumer chainsaws, which are used by non-professionals carry an "ANSI B175.1" federal designation. These chains are low-kickback chains and are well designed to reduce the 'kickback' to prevent an injury while using them. For the purpose of trimming or removing the limbs of trees, these chainsaws that are small in size are useful.

Tree Trimming Tips
If you need information about the rules for tree trimming, check with the local area authorities. When indulging in gardening, a fact to remember is that the owner is responsible for maintaining the clear side-walks and corners bordering his property. In case of trees under overhead electrical wires, the owner should inform the local authorities which can take proper action.

• While tree shaping and trimming, make sure that the main lead branch is maintained on the young trees, so that they grow up into a tall and robust tree.
• In case of small trees, trimming the multiple lead branches is all the pruning you should do.
• Over-trimming will reduce the leafy area and affect the growth rate of the tree.
• As a rule of thumb, cutting large side-branches of trees is not recommended, however, if the need arises, do not use flush cut to do so. It hinders the tree's natural healing process.
