Wow... I hadn't realized that 'Champion' juicers were still made.
When I was a kid, my mom had a Champion juicer... the commercial model. This juicer was huge! I remember that she kept it cleaned and 'bagged' in storage most of the time. When she got it out... was usually after she had bought a 50 pound bag of carrots (and smaller quantities of other veggies).
Then we'd spend a good afternoon 'juicin carrots'. She would have to stop about two or three times and clean out the strainer inside the juicer, as it would get clogged.
We'd get a lot of quart jars of juice - which she'd keep most, and give away some - to friends - no charge.
After the juicing was complete, we'd then spend another 30 minutes or so cleaning up the juicer, and then put it back in storage.
