There are a couple of different axle weights so it would depend on which ones you have. There is an axle weight that is basically a horseshoe shape goes over the axle and hang down a bit below the axle. These I can't give you a price or weight because I have not owned them. If you are talking about the weights in the photo I have several sets and have sold sets. I usually sell for $200/$250. The flat top weights usually weigh 150/160 lbs each. The round top weights are 170/180 lbs each. They are all aftermarket. I've had some that had the Farm hand tag on them. The flat tops are more common. If you have the ones with the indentations on the bottom (on left in second photo) they are made to also fit later models such as the hundred series and thousand series. Indented to sit on top of the axle nuts on the end of the trumpet. Since they will fit the N models and the later models they could be a bit higher in value. Usually most people are looking to add weight in the winter, at least in my area, so it might bring a higher price at that time good luck with your sale. Of course prices can vary depending on your location.
