Slice through the toughest brush or edge with this rugged yet surprisingly lightweight and easy-to-use trimmer. Equipped with a powerful 31cc, two-cycle engine, it features dual piston rings and a chrome-plated cylinder for longer engine life, improved performance, and lower emissions. (In fact, the engine is C.A.R.B.-approved to pass stringent California air-quality standards). A professional-style straight shaft trims under shrubs and low branches, while the head rotates and locks at both 90 and 180 degrees to deftly execute complicated decorative edging. A full 17-inch cutting swath allows you to trim more grass in less time using a 0.08-inch diameter dual line.
The 790AST also comes loaded with convenient features to make yard work easier. The EZ-Start system mean no more relying on brute strength--just flip, prime, and pull without having to adjust the choke. The EZ-link attachment system accepts all 18-inch TrimmerPlus multi-task attachments for unparalleled versatility, allowing you to transform your trimmer into an edger, blower, vacuum, cultivator, and more. Simply slide the shaft of the attachment into the connector until it clicks to lock--no tools are required. The speedspool line replacement system lets you replace line without removing the spool from the cutting head or taking the spool apart, while an adjustable J-shaped handle is safe and comfortable for both left- and right-handed use. This trimmer measures 12 1/2, by 40, by 12 2/5 inches, and weighs 18 1/2 pounds when shipped. --Mary Park
