"It seems there are two sides to this debate. Some farmers believe it's wise to trade every couple of years to keep machinery current and get the best return on your investment (i.e. tax strategy, increased efficiency (because of improved engines and new technologies on equipment), fewer breakdowns with newer equipment)," writes Laurie Potter, Deputy Machinery Editor for Successful Farming.

"However, there are others who believe it's wiser to avoid excessive equipment purchases," she says in a recent Machinery Talk discussion group posting.

"What are your thoughts on this topic? Do you see the wisdom in having newer equipment or is it wiser to keep your equipment purchases to a minimum?" she asks.

Farmers responding to the question argue both sides.

"I think it has alot to do with your ability or time available to do your own repairs.... If you are decent at it and have time to work on equipment you can run an older fleet," said one farmer.

Says another, "Some equipment has been a good investment because it has increased in value or even stayed the same while you still get the use out  of it."

A spirited discussion ranges back and forth across the issue. Read all the farmer reponses and join the discussion here: Machinery Talk.
