The firm also reduced its price target to $80 from $94 on shares of the Moline, IL-based agriculture and construction machinery company.
The downgrade is due to the drop in corn prices, which have fallen to $3.40 per bushel from $4.40 per bushel since June, according to the analyst note.
The lower prices mean that farmers will have less money to spend on farming equipment, thus limiting Deere's sales. Corn prices will most likely not increase because of less than ideal weather conditions along the U.S. corn belt, UBS added.
Th firm expects Deere's farm income to remain under pressure and negative sentiment on the shares to continue, the Fly noted.
Earlier this week, Deere's rating was downgraded to "underweight" from "neutral" at Piper Jaffray due to falling corn and grain prices and their anticipated negative effect on consumer demand for machinery.
