Proper maintenance and adjustment of Stanhay belt and vacuum planter metering units is crucial to achieve the greatest accuracy possible. We've been providing these critical services ever since the S870 was introduced in 1959.

Seed belts, bases, and other common Stanhay repair parts are readily available, and can be ordered by phone. Stanhay parts diagrams are available upon request for do-it-yourself repairs.

Both of our Salinas, CA and Yuma, AZ locations offer Stanhay metering unit and planter repair.

condition of the equipment, but an average tune-up job runs ~$235 per metering unit.

Rebuild services performed:

  • Metering unit is completely disassembled
  • Each part is cleaned and thoroughly inspected
  • Any part that does not meet the tolerances of a new part is replaced
  • Wear grooves in side plate and body are filled
  • Old paint and debris are completely removed prior to repainting according to your color choice, or with the standard "Stanhay-orange" paint.
  • Each unit is reassembled and tested for proper operation and seed belt alignment


Seed Belts & Bases

Any machine must be configured properly to achieve optimum performance. This is especially true of Stanhay planters, which must have the
correct combination of belts, bases, and repeller tires to plant at its greatest accuracy.

Our seed testing system closely approximates field conditions, so we are able to "plant" the actual seed that will be used in the field. This lets us
view the "planted" results before recommending the proper belts and bases for your specific seed.

Choosing the correct spring-base is as important as using the proper belt. If one of the standard bases doesn't meet your needs, ask about our
custom bases.
