I have an SR331415BVE RER I think? Those letters are below the steering wheel. 33" deck Briggs engine. I towed my fat arse at 290lbs. A towable core aerator at probably 60lbs. Think it was 8 cinder blocks at 43lbs each. Finally the wife at 120lbs. Simple math comes to 814lbs. Really put a load on her going up hill and turning the aerator. Cuts like a laser beam with only one blade. Never will sell it. Can't find a more simplistic reliable machine out there that would even compare to the old Snapper build.
