Replacement Components for Any System

Zimmatic components — including center drives, gearboxes and electrical controls — are the preferred after-market choice when repairing or converting irrigation systems from other manufacturers.

Key Replacement Parts:


Tower Control Boxes

Housed in a weather-tight enclosure, these ultra-reliable controls maintain machine alignment during operation. Lindsay technology combined with rigorous factory testing, result in Zimmatics being known as some of the straightest running pivots in the industry. Pivot alignment relies on precision controls that operate in a wide range of environments including; rugged terrain, high winds and fluctuating temperatures. (Conversion kit required for non-Zimmatic pivots)


AT Gearbox

The industry’s largest expansion chamber reduces internal pressure and temperature. Other features include:

  • Cartridge input and output shaft seals that turn with the shaft provide extra protection from dirt and moisture. A special diaphragm design keeps internal components submerged in lubricant during operation 
  • Two large input bearings increase load capacity by 55% 
  • Operating life and increased torque consistency are achieved thanks to a super-strong, cast iron bull gear 
  • Universal mounting pattern to fit all types of machines 
  • Easy-fill design allows routine gearbox maintenance without opening the expansion chamber

Center Drive

the fastest, most durable and efficient in the industry for over 25 years

  • Operates at 480V or 380 V 
  • 43 RPM motor versus others 34 rpm motor. A seven tower Zimmatic pivot can complete a circle in under 13 hours, compared to 16 hours for a competitive motor – 27% faster 
  • Also available: 1.0 hp (59 rpm) motor, reducing rotation time by 37% 
  • Heavy-duty steel stator shell is coated to resist chemicals or corrosive water 
  • Triple reduction spur gear provides the industry’s highest efficiency
