I got my self propelled Ego mower and the 15" string trimmer today along with one regular charger and one quick charger, one 7.5 Ah and one 2.5 Ah battery. I didn't want the blower they had in stock (480 CFM), so they're ordering the 530 CFM blower for me. But . . . . I got about .75" of rain Saturday, 2.15" Sunday, and .3" so far today. So I haven't used the new equipment yet, but I'm sure the yard will need mowing as soon as it gets reasonably dry.
Apparently The Home Depot is the major dealer for Ego, but I decided to go with Ed's Lawn Equipment in Addison, TX. Same price as The Home Depot.
Adam, I guess you know any of their batteries, 2.0 Ah, 2.5 Ah, 4.0 Ah, 5.0 Ah, and 7.5 Ah, will work in any of the tools, but there's a difference in the weight and the length of time they'll run the tool. The 7.5 is the standard in the self propelled mower, while the 5.0 is the standard in the push mower, and the 2.5 is the standard in the 15" string trimmer, while the 2.0 is the standard in the 12" string trimmer.
Another odd thing is that the mower comes with the bag, as well as the plug if you want to use it as a mulcher. But if you want the side discharge chute, you have to request it from the company after you buy the mower, which I did this afternoon. The only problem is that they say 2 to 8 weeks to get it.
