Hi Grassman 177,
There is one weight per kit. Each kit does come with additional, progressively longer bolts. The more weights, the longer the bolts. There is not a "weight chart" to suggest how many weights are recommended per operator weight. The dealer will have to order a kit to see if it is adequate, then order additional as needed. The number of weights is also dependent upon the terrain being mowed. A large operator, going uphill, may require additional weights to keep the front end down.
