Strimmers are available in petrol or electric form. Electric strimmers are further divided into corded and rechargeable cordless varieties. Petrol strimmers require a higher level of maintenance, but also tend to be more powerful. This makes them well suited to tackling tough, overgrown areas as well as everyday jobs. They have the advantage of mobility over mains-powered electric models, though you might look at a cordless strimmer for the same freedom of movement.
Strimmer features include:
- Bump feed head (manual control over amount of line; easier to repair).
- Automatic feed head (simpler and faster to use; more difficult to repair than bump feed).
- Straight shank (durable; well balanced; good for trimming under bushes, hedges and fences).
- Curved shank (cheaper; usually lighter; easily manoeuvrable; good for trimming around flower beds).
