New aluminum crutches were dirt cheap, maybe a wheelchair is too, thanks for the insight... I have very good handrails to get up & into combine cab and I'm going to strap on a knee pad too. I've got a heated seat, I've always used it all day on low, does wonders to keep from cramping up. I've built up a lot of strength in my arms & left leg the last month, lost more than 15lbs too which is good.
