GREASE COMPATIBILITY
All greases are not compatible. Grease incompatibility will decrease the lubrication ability
of the grease, and can cause premature part failure.
Grease can have mineral or synthetic base oils and thickening agents such as lithium,
calcium, barium, sodium, or aluminum
What We Use:
- Progressive uses Shell Gadus S2 V220 2
- This grease has: - A mineral oil base
- A lithium-12 hydroxy thickener (“lithium” thickener)
- Extreme Pressure additives (EP)
- An NLGI Grade 2
Recommended Grease Properties
The grease you use for this machine must have these properties:

NLGI grade 2

Lithium thickener (NOT LITHIUM COMPLEX)
1

Kinematic Viscosity at 40°C is no greater than 220 cSt

Dropping Point Less than 400° F

General Purpose Grease, Not Heavy Duty

No MOLY (molybdenum disulphide) additives in the grease
2

No synthetic grease
3

No High Temperature Grease
4
Notes on grease compatibility:
1) If a thickener other than lithium is used (including lithium complex), the existing
grease will be contaminated and the lubrication properties may be lost leading to
component damage.
2) Molybdenum Disulfide (Moly) is an additive used in slow moving, extreme load
applications. The particles in the “Moly” grease can actually increase bearing wear
in a high speed mower application. Generally speaking Moly based greases will be
grey in colour or have a metallic sheen.
3) If synthetic base oil is used rather than mineral base oil, the grease will be
contaminated; the lubrication properties may be lost leading to component damage.
4)
We do not recommend the use of “High Temperature” greases, mower component
temperature should never reach temperatures above the level at which general
purpose greases can operate. “High Temperature” greases may contain thickeners
that are not compatible with Lithium-12 Hydroxy based thickeners.
Grease with these features is considered to be a “General Purpose Grease”. Use on all
grease point locations on your Progressive Mower. Check the properties of the grease you
wish to use with your supplier prior to use.
