Center Drives Engineered for Reliability

Valley Center Drive…engineered for reliable service

The Valley Center Drive is built stronger, lasts longer and uses less energy than other irrigation drive motors. The standard-speed motor has the lowest power requirements in the industry. The high-speed motor has a nine-hour rotation. Valley Center Drives are designed for easy maintenance in the field.

Center Drive Features Center Drive Benefits
Steel gears Provide more strength than powdered metal
Aluminum finned housing Runs 20º F cooler for a longer motor life. No paint to chip, scratch or corrode
Internally vented junction box Prevents moisture and contaminants from corroding the wire connections
Crop guard Protects shaft seals for extended life
Integral pinion gear Eliminates coupler, improves reliability
Helical gears More tooth contact than spur gears, providing more torque capacity and quieter operation
Special motor windings for high-torque applications 40% higher operating torque than the competition
  • Large 1 3/16” motor shaft
  • Pinion gear — integral with motor shaft
  • Extra-large intermediate gear bearings — assure longer life
  • 25º tooth angles — provides 40% greater load capacity and wear resistance than other manufacturers’ 14 1/2º  tooth angles
  • Double output shaft seals
  • Built-in crop guard over U-joint — prevents crop wrapping in or near oil seals
  • Double reduction gearing — requires fewer gears, shafts and bearings for greater reliability and efficiency
  • Stator — can be replaced independent of rotor, and is held in place with corrosion-resistant, stainless steel bolts for easy maintenance
  • Extra — large motor bearing
  • Exclusive coating — applied to internal surfaces to prevent corrosion
  • Watertight seal — between housing components
  • Finned aluminum housing — for cool-running efficiency. Operates at temperatures 20° F (11° C) lower than comparable motors with steel housing, because the Valley aluminum housing and fins dissipate heat more effectively. This doubles insulation life and increases motor life
  • Case-hardened steel helical gears — more teeth meshed at all times for smoother power transmission.
  • Drain plug — easily accessible, extra large
New!  VS-7000 Center Drive


VS-7000 Drive Train is Now Available

The VS-7000 drive train is a lower priced option on the 7000 series pivots. VS stands for Valley Specified performance. The VS-7000 will provide a substantial savings per drive unit. It is important to note that the VS-7000 and Valley drive trains cannot be mixed on a given pivot. The first span selection determines which drive train choice must be used for the entire machine.

The VS-7000 drive train consists of:
• New 34 RPM & 68 RPM center drive assemblies
– .6 HP  or 1.2 HP Baldor motor with a corrosion resistant painted steel housing
– Current Omni helical center drive gearbox
– Same amp draw as current Valley helical center drives
– Same torque rating as current Valley helical center drives
– Assembled and tested at McCook

• New wheel gearboxes
– Front and rear individual input worms (not dual input)
– Mounting is the same as Valley gearboxes
– Ductile worm and cast iron bull gear for longer life
– Made in China by Omni to Valley specifications

VS-7000 Warranty
• Six (6) years or 6000 hours, whichever comes first
– Parts, labor and travel same as Valley gearbox
