I just obtained my late father in-law's Toro personal pace mower. He used it for probably 10 years. Mowed 1/3 acre every other day until he was 90-91 years old. I mowed it once in a while when he wasn't feeling well. Then they got a lawn service and he passed away about 2.5 years ago. So it sat in their shed unused for 4.5 years. I ran it out of gas when I put it in his shed and that's all I did to it.
I brought it home last weekend, checked the oil, put gas in it, and honest to goodness it started on the 1st pull.
I really like the personal pace feature. It self-adjusts instantly to your walking speed. You just hold the engine kill bar down, rest your hands on the handle and start walking. It takes off on its own. Slow, fast, doesn't matter. You feel nearly no resistance. It's like going for a walk.
