I have a similar setup. This past summer being the first one with my Landroid, I tried running a wire between the cracks of the sidewalk that run every two feet or so. While I love my Landroid, I wouldn't recommend running the wire to that area.
Due to the area in front of my house being narrow, the Landroid would often bounce around off the permitter wire excessively. Also, the curb between the street and my parkway is rounded. It took many readjustments before I was able to reach the point where it wouldn't slightly slide down the curb and my phone would start beeping "Outside of Permitter Wire".
I bought a cheap, lightweight electric Black & Decker Three-in-One Mower, Trimmer, Edger that I primarily use as my trimmer around my fence line. Next spring, it is unlikely that I will lay the perimeter wire to that small area and instead, I'll just quickly trim it with my electric trimmer. For me, it is much less of a hassle.
I do use a weed whacker sometimes, I have a rechargeable one that is lighter, but can only do it for so long before my arm gives out. I found this at Amazon based on a redditor suggestion: Cordless mower.
This little compact mower was made for epople like you:
