</font><font color="blue" class="small">( Indydirtfarmer, I have two 71's, where do I get a fiberglass planter box. Also interested in the fertilizer attachment, what does it look like, what drives it? Thanks Rodney )</font>
Deere MIGHT still have a few fiberglass seed hoppers in their system. I bought a 16 row planter with them already on it. Most people prefer the smaller ones for garden use. A pair of the fibergalss hoppers will hold enough seed corn to plant 7 to 9 acres without stopping. If you have a good set of the smaller metal hoppers, I know of a TBN member that's wanting to swap a set for his fiberglass set. PM me and I'll try to make the connection for you.
The fertilizer attachment I'm working on is a liquid system. It will be "powered" with a 12V "on demand" type of electric pump. I'm using a pair of (rectangle) 20 gallon plastic tanks mounted over the toolbar. I'm still working out the details on them.
I'm just starting to work on a granular fertilizer attachment. Lots of details to work out there.
