Land is pretty much a purely speculative investment.  The only way it works is if you assume it will appreciate.  I have only seen a few short instances where land would actually earn enough to pay it's own way.  Machinery, on the other hand, is really a consumable.  You assume it is going to be used up.  The key is to use it to make money faster then it gets used up. 

The way I look at it is that the machinery is the part of the business that makes the whole faming deal possible.  Machinery management is the area where we feel we have been able to rise above the competition, if you want to look at it that way.
