What do you mean by heavy leather? If you're talking about things like harness leather it will sew it if you go very very slowly, but you will only be able to use thread up to size 207. The leather pieces in the picture are 1/4" thick, and were sewed on my Singer long arm 144W204 which is a much heavier machine. If you're talking about upholstery grade leather, it will handle it with ease.
