Here's a photo of my first tumbler.
No crank, it easily rolls on runners on its base.
Also the base is a reservoir for the compost tea that leaks from the barrel.
Has a hookup for a hose...so you can get tea whenever you want.
I use the tea very diluted for my orchids and other house plants now instead of storebought fertilizer.
As you can see, it is VERY low profile and right now is hidden behind 2 holly bushes behind my garage.
In the summer I tumble it about 2-3x per week, and in the winter, maybe once a week.
If you want to move it, just simply roll it off its base, and then roll it to wherever you want it.
I have 2 of them now, the other one I ordered in dark hunter green, to be for my 'grren' batch. (not composted yet)
The black one is not for my ready to use batch.
