Press Wheel wear checks

Firms the soil onto the seed for even emergence. Here's how to tell when it's done.

Press Wheel

Grab the press wheel with one hand and steady the arm with the other, checking for any left-right play or a knocking noise. Either means the bearing is starting to collapse and should be replaced promptly. Spin the wheel and listen: a dry rumble means the bearing internals are worn, and a wheel that spins too freely with no resistance points the same way. Check the tyre for wear, warping or brittleness, and make sure no dirt is getting between rim and tyre and walking the tyre off the rim. Worn bearings or tyres give inconsistent firming and poor seed-to-soil contact.

Press Wheel Spring

Springs lose tension and set over time, and a tired spring won't hold the downforce the wheel needs to run true or firm the furrow. Check for cracks, corrosion and any permanent deformation, and compare free length against a new one. Replace in matched pairs where left and right work together, so downforce stays even across the opener.
