Wheelbarrow...300lbs, dolly...300lbs, The extended dolly, Cylinder holder, Rock mover and plant mover are each 80lbs., Trailer mover 100lbs tongue weight and trailer weight 1,000lbs, bag holder...40lbs. I work mine pretty hard and I have used all the attachments. It is SOOO much better than a wheelbarrow except for the fact that the handles are low and I find pulling it is easier on my back and I am 5'5". I use this so much more than I really thot I would. Moving rocks and flower pots is SOO much easier and the fct that it doesn't tip is awesome for hauling any load. Hope this helps. Merry Christmas!!
