I have a 450 bushel grain tank extension, made by Dick's Welding is Windom Minnesota. It is a 4 piece extension that will fit on a 9860. If you are interested I can give you the number.
Will make total bin capacity 435 Bushels. Price is around $900 i think, i am a maurer mfg dealer, email me if you are interested and i will get you an exact price. allen
just a thoughtIJ if ya have any wheel trouble or any kind of prob for that matter, what does deere think about these mongo hopper exten.IJIJ does the warr. go out the windowIJ 435bu is alot man. wish we could raise that good of corn to not be able to make it to the end of the field lol. and maybe its just me, but i think thats the whole logic for grain carts. just my opinion mit9750
