~ Standard 30" Spinner Assembly​​  ~​​​​​​​​​​​​​​

The adjustable spinner assembly is operator friendly and has predefined settings, that take the guess work out of spreading lime and fertilizer.  The adjustment arm, on the spinner assembly, eliminates the possibility of costly repairs due to jack or electric actuator freeze up.  The spinner assembly, along with the material divider, work together to spread material as far, as wide, and as consistently as any known spreader on the market.
The spinner drive features
a jackshaft assembly that minimizes the troublesome maintenance of the hub style spinner.  The seal is designed to last for the life
of the machine with proper maintenance.

The user friendly spinner  assembly by Force Unlimited, produces a spread pattern and spread width that is unsurpassed and does not vary when using multiple bins.
