Concept: Greases on the farm — PCL PRECISION line and where each thickener belongs
Confidence: Verified for PCL grease thickener types and PRECISION product line; Estimated for SWO-specific greasing discipline patterns.
Thickener types — what each one is good for
| 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 |
PCL PRECISION line for SWO farms
- PRECISION XL EP2 (NLGI 2, lithium complex, EP) — the workhorse multi-application grease. Operating range typically −20°C to ~150°C.
- PRECISION XL EP1 — winter alternative to EP2, better pumpability below −20°C.
- PRECISION XL 3 Moly / 5 Moly EP2 — heavy-duty shock-loaded points (kingpins, fifth wheels, planter linkages).
- PRECISION GP EP2 — general-purpose lithium soap, lower price tier, for less demanding chassis points.
Greasing discipline by equipment
Planters
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.
Combines
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.
Tractors
Loader pivot pins, 3-point hitch linkage, PTO shaft U-joints — the most commonly under-greased point on the farm.
Manure equipment
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.

Frequently asked questions
What grease thickener belongs on a typical southwestern Ontario farm?
Lithium complex is the default — high dropping point (~260 °C), good water resistance, EP-capable, slightly higher cost than conventional lithium. PCL PRECISION XL EP2 is the southwestern Ontario default cartridge for general farm chassis, low-load points, and most field equipment. Calcium sulfonate is reserved for manure equipment and wet barn applications where water resistance and corrosion protection dominate.
When does moly-fortified grease earn its place?
Moly-fortified greases (typically 3–5% MoS₂) are boundary-lubrication greases for high-load, low-speed applications — pin and bushing joints on excavator booms, articulated loader joints, and similar high-shock points. On a typical row-crop farm the moly-fortified SKU is a minority-volume product reserved for those joints; the lithium-complex EP2 covers most of the farm.
How should greasing discipline differ by equipment in southwestern Ontario?
Manure and wet-barn equipment needs calcium sulfonate for water-washout resistance; row-crop tractors and planters live on lithium complex EP2; high-load excavator and loader pins justify a moly-fortified SKU. The mistake to avoid is one-grease-fits-all from the same cartridge gun — it works in the short term but lets water push the lithium-complex grease out of manure-equipment bearings.
