Gravely® introduces the 2013 changes to the X-Factor decks. These changes have already gone into production on Pro-Turn 400, Pro-Turn 200 and Pro-Turn 100 models with a serial number greater than 20,000. New Red Gravely Commercial Spindles The spindles have had numerous interior changes to improve reliability and longevity. The new spindles are the same shape and profile as previous black commercial spindles and can be identified by their red exterior paint. These spindles are still covered by a 3-year commercial warranty. Discharge Opening The discharge opening has been increased by 10-20% (depending on deck size).This change will improve clipping dispersal, especially in demanding cutting situations. Optimized Discharge Chute Profile The chute profile has been optimized for even clipping dispersal and reduced windrowing. Standard Adjustable Vacuum Baffles Vacuum baffles will be standard on Pro-Turn 400, Pro-Turn 200 and Pro-Turn 100 models, allowing the deck to be adjusted depending on the conditions for minimum performance. Note: New spindles, larger discharge openings, and optimized chute profile are also now standard on Pro-Master 200, Pro-Master 320, Pro-Master Rapid XZ, Pro-Turn, ZT HD, and Max Zoom® models with serial numbers greater than 20,000.
