New from Sunflower is the 1800 series tandem disk harrow. The new machines combine bigger blades and wider blade spacing with larger frames to easily cut through compacted soils and thick crop residue.

There are two models, each with a variety of widths and configurations. The SF1830, with cutting widths between 22 and 39 ft., weigh between 23,771 and 37,568 lbs. The SF1810 model cuts from 14 to 17 ft., weighing between 11,152 and 13,580 lbs.

The series can be configured with 28- or 30-in. plain or notched disk blades spaced at 11- or 13-in. intervals. Some models feature spring-cushion gangs. Heavy coil springs allow the assembly to pivot. For more information go to www.sunflowermfg.com.
