People do it all the time. Just remove the rear mouldboard, etc., and it works the same.
Depending on the soil, the L3130 may struggle just a bit to pull a two bottom. Can't tell the share size from the small picture but it looks to be 16". That would be more difficult to pull than a 14" or 12" of course. Fill the FEL with plenty of weight and run in 4WD.
Thanks, he has come down on the price a bit on craigslist, I know I can't pull 3, doubt 2 (at least 16 as you say) but was thinking if it can be taken down to 2 or even 1, perhaps it would work for me...
