Well gang, here is a topic that I haven't seen a lot about on the internet. There is tons of information on rear ballast, but front ballast is just not talked about at least not in depth anyway. And it just so happens I have been doing research on it as well as applying it. First of all let me tell you how this all started. After using my 3pt sprayer, 3pt spreader, box blade, and tiller I felt that I was on the edge of improper ballast for the front. Yeah, chores were being accomplished but was I really safe and efficient? My conclusion was no and thus I quickly ordered up my two extensions and seven weights as that is what the Deere info. said they would hold. At the risk of looking foolish, I will let you know of my blunder, though in the end it turned out OK. After my rush to place the order, I THEN consulted the manual and to my surprise I found that the front of the machines will accept the weights without the extensions. The frames already have the bracket and the holes for the lock rod. What I found was the 2305 will hold 5 weights and the 2520 will hold 3. By adding the extensions I will be able to add the full seven weights to both machines, though I probably would be OK with five on the 2305. I know why most people do not add these weights and extension, the $$$$$ adds up quickly. The extension alone is $180 and each weight is $52. Now for the 1000 series, apparently, per the manual you CAN NOT ADD FRONT WEIGHTS WITHOUT THE EXTENSION.
Before bolting on the extensions I had a concern, would they work with the front quick attaches without interfering. As you can see, they can not. So, what I decided is that the extension would probably be on in the summer and the Quick hitches will be on in the winter any way. Somewhat of an inconvenience but it is only a couple of bolts. I have attached excerpts from each of the manuals as well as some helpful photos. Also, it looks like the same bracket (part number LVB25363) is used across the 1000 and 2000 series machines. The attached photos are of the tractors without the extensions.
