Curious if anyone has traded there SDX for the new precision disk drill with the parallel linkage? After owning a sdx drills for 10+ yrs the new drill opener assembly seems dinky in comparison. How does the new seed tube scraper work? Does it plug in wet conditions. Straw plug it up etc? How is not having a seed firming wheel option? Possibly leaning toward a 50' when available or maybe finding a lower acerage sdx40 and rebuilding.

Case-IH SDX vs Precision Disc 500

Curious if anyone has traded there SDX for the new precision disk drill with the parallel linkage? After owning a sdx drills for 10+ yrs the new drill opener assembly seems dinky in comparison. How does the new seed tube scraper work? Does it plug in wet conditions. Straw plug it up etc? How is not having a seed firming wheel option?

The move from 22" blades to 18" blades is wonderful (less hairpinning), unless you routinely seed at 5" depth. The P-500 boot/scraper is much improved and gets the seeds to the bottom of the furrow rather than scattering them everywhere like the SDX did. But the loss of the seed-lock wheel is a disaster. Although we at Exapta have an upgrade kit for the P-500 drills to do in-furrow seed firming with a Keeton & Mojo Wire. Exapta Solutions :: The Thompson closing wheel and bracket for CIH Precision-500 drills and Exapta Solutions :: Mojo Wire stiffener for Keetons
and Keeton Universal Kit, Dry From what we hear from former SDX owners moving to the P-500 with our upgrades, they are extremely pleased with seed placement. The P-500 has amazing ability to cut heavy thatches of straw, cut the furrow to a precise depth, and get almost all the seeds to the bottom of the furrow. Too bad Case-New Holland dropped the ball on the seed firming. And they are scrambling to improve their furrow closing too, by changing the angle of the packer wheel.

You ahould be able to get the parts from case ih still. Pin, spring, arm, wheel bushins. The bushins are a PITA to put in. I made a tool to install them. Also put a grease fitting in there while I was messing.
