I purchased the EGO 56V 21" Self-propelled mower with the 7.5Ah battery nearly 1 month ago. It worked well on deck level 2. I was able to cut just under 7000 sqft of lawn on one charge. This month, not only can I not finish the same amount before my battery dies, I cannot even finish with the 2.5Ah battery after. To make matters worse, my mower also no longer shoots all the mowed grass into the grass catcher bag. It regurgitates much of it back on to my lawn. Does anyone else have this problem?
