The Ryobi RY40780 is the complete kit version of Ryobi's 40V HP brushless 8 in. stick edger, bundling the RY40708BTL edger with a 40V 4.0 Ah lithium-ion battery, a fast charger, and a blade wrench. The upright stick edger design keeps operators in a comfortable standing posture throughout the job. The brushless motor pairs with both a variable speed trigger and a 2-speed switch for precise blade speed control. A 5 in. adjustable rear wheel handles uneven terrain, and 5 depth positions span 0.5 to 2.25 in. for flexible cut depth. The spindle lock allows quick blade swaps, and the included blade wrench ensures you always have the right tool on hand. At 13.3 lbs., the kit is one of the lighter 40V edger configurations available.
What is included with the RY40780?
The RY40780 kit includes the RY40708BTL 40V HP Brushless 8 in. Stick Edger, one 40V 4.0 Ah lithium-ion battery, one 40V fast charger, and a blade wrench. The blade wrench is a useful bonus that the tool-only SKU does not ship with separately.
How does the RY40780 compare to the RY40760 9 in. edger kit?
Both are 40V HP kit-level edgers that ship with a 4.0 Ah battery and charger. The RY40780 uses an 8 in. blade and a stick (upright) handle design, weighing 13.3 lbs. The RY40760 uses a 9 in. blade with a 3-wheel rolling design and a rotating handle that supports trenching. The stick edger is lighter and easier to maneuver for standard sidewalk and driveway edging, while the 9 in. model handles heavier cuts and landscape bed definition.
What is the difference between the RY40780 and the RY40708BTL?
The RY40780 and RY40708BTL use the same edger platform. The RY40780 is the full kit that includes a 4.0 Ah battery, fast charger, and blade wrench. The RY40708BTL is the tool-only version for buyers who already own Ryobi 40V HP batteries and want to avoid paying for redundant battery equipment.
How much does the RY40780 weigh?
The assembled weight of the RY40780 with battery installed is 13.3 lbs., making it one of the lighter full-kit edger options in the 40V HP lineup and easy to handle for extended edging sessions.
Can I use higher capacity 40V batteries with the RY40780 for more runtime?
Yes. The RY40780 edger accepts any Ryobi 40V lithium-ion battery. Swapping the included 4.0 Ah battery for a 6.0 Ah or 7.5 Ah battery will increase runtime per charge proportionally. The tool's weight will increase slightly with a larger battery, but performance and compatibility are unaffected.
