I just took position of my first Deere, a 2520 with the 200 CX & 46 BH. The dealership did "in my opinion" a poor job in going over the tractor upon delivery. To me, after all the reading on this tractor I have very little power when it comes to the loader & backhoe. Are there certain rpm's needed to use the loader or bh? Any thoughts or suggestions or tips would be greatly appreciated. Also, looking to add a thumb to the bh, but i do not see one from JD.
