The section 179 bonus depreciation expired January 1st. That allowed a bonus depreciation of up to $500k (50% of investment) in addition to the normal accelerated depreciation schedule.
I would expect that many of Deere's small customers accelerated their purchases into 2013 so I wouldn't be surprised if the 1st couple of quarters of 2014 show a slowdown for producers until things level off.
One of our divisions had a hectic 4th quarter and a slower than normal 1st quarter. Things are getting back to normal but those deliveries won't occur until later this year.
