Confidence: Verified for PCL grease thickener types and PRECISION product line; Estimated for SWO-specific greasing discipline patterns.
| Thickener | Strengths | Weaknesses | SWO application |
|---|---|---|---|
| Lithium soap (conventional) | General purpose, moderate temp/water resistance | Limited high-temp, water washout | General chassis, low-load points |
| Lithium complex | Higher dropping point (~260°C), good water resistance, EP-capable | Slightly higher cost | The default for farm equipment — PCL PRECISION XL EP2 |
| Calcium sulfonate | Exceptional water resistance, EP, corrosion protection | Higher cost, heavier at cold start | Manure equipment, wet barn applications |
| Moly-fortified (3–5% MoS₂) | Boundary lubrication under shock load | Not for high-speed bearings | Pins, kingpins, planter parallel-arm bushings — PRECISION XL 3 Moly / 5 Moly EP2 |
| Polyurea | Long electric-motor bearing life | Not EP | Less common on farm |
Pre-season service is the single most important grease event on the farm. Every parallel arm, gauge wheel pivot, closing wheel arm, and meter drive needs attention. Common neglect: row-unit drive shafts and pivot bushings on the meter shut-off. Moly grease (3% or 5% MoS₂) is appropriate for heavy-load shock points.
Daily greasing is operator-manual reality. JD S-Series and Case-IH 8/9250 each have 40–60+ grease points. Common neglect: feeder house chain idlers, header drive U-joints, unloading auger swivels. Most in-harvest failures are bearing failures preceded by missed grease events.
Loader pivot pins, 3-point hitch linkage, PTO shaft U-joints — the most commonly under-greased point on the farm.
Calcium sulfonate grease justifies its price here. Standard lithium complex washes out of slurry tanker pump and agitator bearings within hours of exposure. Wet-barn dairy equipment is the other application where calcium sulfonate's water resistance pays back the premium.
