From the sales brochure on these pickers:

319 gathering unit (with sub-frame, axle brackets & cylinders) - 2519 lbs.

322 12-roll husking bed - 1468 lbs.

So you have right at 2 tons of steel/iron there.

And just in case anyone needs to know the weight of the rest of the attachments:

320 8-roll husking bed - 1238 lbs.

315 mounted sheller - 1167 lbs.

317 mounted grinder - 1340 lbs.

308 hopper & elevator - 622 lbs.

Hope this helps!
