I bought a 45" double row disk harrow for my Kubota BX2350. I have messed with it a little and plan on using it a great deal as soon as the weather breaks. Has anyone used a harrow such as this one and had to add weight? I know I will need to add weight on order to get it to dig into the ground appropriately but do not want to add too much and damage the disk or overload my hydrolics.
