ProdunkHoops said "The system being installed here is the Pro Dunk Platinum which does require a 4 foot hole. The Silver and Gold models require only a 3 foot deep hole. hope that helps!" Platinum instructions say to dig a 24" by 48" hole. No way is that a 24" square hole in this video. Get ready to buy about thirty-two 60lb bags of concrete to fill that 24" by 48" hole.
This might be under warranty. Please send in a photo of your basketball goal along with your order number to support@produnkhoops.com and we'll get you taken care of.
