Any crop producer who does not enjoy planter maintenance and cares about consistent seed placement and depth (which = higher yields). QEM parallel arms wear quickly. You can either replace the entire arm (expensive and does not fix the root issue), buy a kit and rebuild them yourselves (which is a total pain) or upgrade your current parallel arm through our upgrade program which offers an improved, longer lasting bushing and sleeve design.

The general rule of thumb is to replace the arms when there is 1/2" or more play when you lift up and down on the rear of the row unit. If someone is using an Automatic Hydraulic Downforce system, we generally recommend replacing them a little quicker since these systems are using a load cell to control them, and the more vibrations that the row unit has, this will diminish the performance of the downforce system.

A carbon alloy steel which is hardened and given a protective coating in order to protect against corrosion.

When there is over 1/2" play in upgraded arms, because of the bushing design, it should be only the bushing at first that needs to be replaced. In theory the sleeves will also wear eventually, however these are also replaceable. So as with our solution, you should never have to replace your arms again.

Get in touch with anyone in parts or sales at Regier Equipment and we will get your upgrade scheduled. The machining of the arm requires a very particular machine and skillset that we have set up with a local machinist. We will get your upgrade scheduled (the sooner the better).
