Daddy was raised on a farm, as he never tires of telling me, and sometimes we do “farm work” together. Or at least, that’s what I call it. He calls it sitting in the yard watching Mommy work on her roses. While it’s true that his wheelchair limits the amount of actual digging he can do, I think that problem would be solved if he’d just get me a tractor. I saw one on TV and I’m pretty sure that’s what we need to get our “farm work” done faster.
I think this one should just about do the trick — don’t you?

WOW, that is some hunking tractor! Even has a planter in the front.
BB, you could also ask your Daddy to get a souped-up engine in the tractor then you could REALLY have a lot of plant digging, howing, planting, AND harvesting.
