I am watching a friends home while they are away on vacation and he lent me his ancient roto tiller so I could till my garden. Kind of a policy of mine to return borrowed items in better condition than I got them, and this will not be too difficult as the thing is falling apart.
This tiller is so old I cannot find a model #, only a serial # which seems rather useless. All I really want to do right now is tighten the belts because the forward belt is so loose, I cannot even get it to till anything with more resistance than water. The only adjustment I could find was here:

But as you can see on the reverse side:

It is as low as it can go.
Would swapping the two belts make a difference? (see pics below)
Is there any other way to tighten these belts?
Is there any way to find a manual for this thing online with only a serial # so I can get new belts?
Thanks!
