Factors such as price, performance and durability are important considerations in choosing garden tools and power equipment, but, if a tool or machine is uncomfortable or awkward to use, you will regret buying it. The interaction between you and the tool or machine is called ergonomics.
“Ergonomics is the application of scientific information concerning humans to the design of objects, systems and environment for human use. Ergonomics incorporates elements from many subjects including anatomy, physiology, psychology and design. Ergonomists apply their diverse knowledge to ensure that products and environments are comfortable, safe and efficient for people to use. Ergonomic design is a way of considering design options to ensure that people's capabilities and limitations are taken into account.” (from The Ergonomics Society Web site)
Another way of looking at this is that a tool or machine should fit you and be natural to use; you shouldn’t have to adapt to the tool or machine or be uncomfortable using it.
Examples of Ergonomic Problems
These are all examples of ergonomic problems. Some of these problems continue as long as you use the tool or machine. Others become less of a concern as the operator learns to accommodate them. Ideally, the operator should not have to learn to accommodate the machine; the machine should be designed to accommodate the operator.
Examples of Good Ergonomics
Considering Ergonomics in Your Purchases
Probably the best way to evaluate the ergonomics of a tool or machine is to spend some time operating it. Even then, some ergonomic problems will not show up immediately. For instance, the string trimmer wrist strain problem may not be noticed until the tool has been used for 15-30 minutes. It is seldom possible to operate a new tool or machine for a significant length of time before purchasing.
An alternative is to talk to other owners and discuss their experiences using the equipment. Even if you can’t operate the equipment prior to sale, at least handle it and try all the controls to be sure they are comfortable for you. If they aren’t comfortable initially, they will probably feel worse after substantial use.
Ergonomics is valid concern when purchasing a tool or piece of power equipment. Many manufacturers work hard to provide good ergonomics; others do not. If you plan to use a tool or machine for hard work, you want it to be comfortable and efficient to use. Most of all, you want a tool that fits you, not a tool to which you must adapt.
