in another thread you posted a picture of the wieght kit for them, and it looks nice and i thank you for that. i have a question though. my dealer has priced them for me, but shipping weight is about 17lbs. is the total kit with all wieghts 17lbs? or are each individual wieght 17lbs? i need to know if the kit is one weight, or all three wieghts pictured, and total weight of each individual weight etc. trying to discern if i buy the kit, then if i have to purchase additional weights or all of them come with it? and how much total can be placed on the mower?
