AIR CUP 101

The heart of the Lockwood Air Cup Potato Planter is the vacuum valves. Poorly distributed vacuum and wasteful leaks greatly affect planting consistency and fuel efficiency. Significant gaps between stationary and rotating valve seal surfaces are a major source of vacuum loss. A good indicator of the planter's vacuum efficiency is the engine speed required to pull adequate vacuum across the machine. If the speed is too low, many tubes will skip; if the speed is too high, the tube will plant doubles.

Compare this to the RocketValve™ upgrade for the Air Cup Rotating Valve.

 

Our test client in Eastern Washington was running his tractor at 1800 to 2000 RPM to operate the potato planter. After the EIC RocketValve™ upgrade, he was able to throttle down the same machine to 1400 RPM, which is about the minimum needed to keep the tractor and implement running efficiently without stalling. This 23% - 30% reduction in RPMs saves fuel and wear on the tractor - all the while improving the efficiency of the planter.

Wear protection of the stationary valve seal surface is critical to the efficient operation of the Air Cup vacuum valve. Wear can dramatically affect the vacuum performance of the valve, requiring routine replacement of both the stationary and rotating valves. EIC's RocketCoat™ surface treatment eliminates this wear and extends the life of the stationary valve indefinitely.

The Solution is the RocketValve™ retrofit:

  • Precision machined and RocketCoat™ stationary valve
  • Precision reamed stationary valve bearing
  • Upgraded ground and polished Chromalloy shaft with bearings installed
  • Upgraded precision machined hub and backing plate installed
  • Re-machined and modified plastic rotating valve
  • Rotating end bench assembled to optimize precision and ease installation

Your Revenue Will Benefit By:

  • Reduced skips and doubles - consistent planting will increase yield
  • Reduce premature wear and part replacement
  • More efficient tractor operation and reduced fuel cost
  • Easier installation - rotating valve comes preassembled

RocketValve™ Makes You Money

The Lockwood Air Cup potato seeder is a wonderful machine employing advanced seeding technology. However, planting inconsistencies still plague many of these machines due to:

  • Stationary valve wobble
  • Eccentric and mismatched stationary and rotating valves
  • Significant gaps between the valve mating seal faces

THE PROBLEMS:

  • Inconsistent vacuum from valve to valve
  • Inconsistent vacuum within the rotation of each valve
  • Uneven wear within the valve
  • Increased required fan speed and fuel consumption

THIS CAN MEAN:

  • Double or triple plants
  • Skips (misses)
  • Premature valve wear
  • Increased fuel costs
  • Inefficient operation
  • Lost revenue

Making a good machine great: Our RocketValve™ upgrade optimizes vacuum distribution across the machine by using redesigned, precision machined components and our famous RocketCoat™ stationary valve seal surface coating. The result? Improved planting efficiency and reduced installation hassles.
