@MDA : do you have an extra spring on the seed firmer ? As standard they are not stiff enough, especially at high speed.
The other thing on them is that they do wear, and with a lot of acres/year on the drill they will need to be changed every other year (as seen on precision planters equiped).
When you say seed firmer, do you mean our spiked closing wheels at the back? Originally we pinned them into a fixed position behind the disc but it soon became apparent that they needed to articulate in their own plane separate from the disc to do a consistent job of following the seeding trench. The weight of the wheel and linkage on its own seems to be enough for them to do their job in good to average conditions. We tried adding ballast weight last week to a few but they dug in too much and created too much disturbance. We may try again with less weight or even an adjustable spring loaded linkage. Our spiked closing wheels are designed hopefully to remain effective as they wear, will be easy to change and will be cheap compared to other types of closing wheel. Made from hardox, you should get pretty good wear rates!
