Farm equipment lives a hard life. Loader pins carry shock loads, baler bearings spin in dusty heat, and three-point hitches sit in mud and rain all season. The wrong grease washes out, pounds out of the joint, or hardens in winter, and then a five dollar fitting becomes a failed bearing in the middle of harvest. Choosing a grease built for high load, water, and temperature swings is one of the cheapest forms of insurance on a farm.
We pulled the most trusted greases used on tractors, skid steers, augers, and implements, then judged them on load carrying, water resistance, pumpability in a grease gun, and how well they stay put under vibration. Below are seven products we would actually run on our own equipment, ranked best first, with honest notes on where each one falls short.

1. Lucas Oil X-Tra Heavy Duty Grease: Best Overall
Lucas X-Tra Heavy Duty earns the top spot because it does the one thing farm grease has to do, it stays where you put it. On loader pins, bucket pivots, and PTO slip joints it forms a stringy, tacky film that shrugs off vibration and shock loading instead of squeezing out the side of the joint. The lithium complex base gives it a high dropping point, so it does not run out of hot bearings on a long day of baling or augering.
Water resistance is where it really separates from cheaper general purpose grease. We hosed down greased fittings and it held its film instead of turning milky and washing away. The honest weakness is the tack itself, it can sling off fast-moving parts and make a mess, and in genuine cold it gets stiff enough that a hand gun takes real effort. For a year-round all-rounder on mixed equipment, it is still the one to beat.
- Heavy tackifier holds to vertical pins and pivots under vibration
- Strong water washout resistance for muddy and wet field work
- Pumps cleanly through hand and pneumatic grease guns
Pros: Excellent stay-in-place tack on loaders and hitches; Holds up to shock and high pin loads; Resists rinse-out in rain and washdowns
Cons: The heavy tack can sling onto nearby surfaces; Very stiff to pump in deep winter cold
2. Mystik JT-6 High Temp Grease: Best for High Heat
Mystik JT-6 is the grease a lot of farmers have run for decades, and for good reason. As a lithium complex multi-purpose grease with a high dropping point, it is happy in hot wheel bearings, PTO shafts, and any chassis point that sees real temperature. If you want one tube and one cartridge that covers nearly everything on the place, JT-6 is the safe, proven answer that simplifies your shop shelf.
Its mechanical stability is excellent, it does not soften and pump out under continuous working load the way some budget greases do. The trade off is that its tack is moderate rather than aggressive, so on slow heavy pins exposed to driving rain it is a small step behind the stickiest options here. For heat and all-around reliability, though, it is hard to fault and easy to find.
- High dropping point for hot wheel bearings and PTO components
- One grease covers chassis, bearings, and implement points
- Good mechanical stability under sustained load
Pros: Handles heat without thinning or running out; Genuinely multi-purpose across a whole fleet; Long, trusted track record on farms and fleets
Cons: Tack is moderate, less grabby than dedicated sticky greases; Not the absolute best in standing water
3. Valvoline Crimson Grease: Best Water Resistance
Valvoline Crimson is built for the wet end of farm work, the loader that lives in the feedlot, the implements parked outside all winter, and anything that sees pressure washing. Its standout trait is water washout resistance, it clings through soaking and hosing where ordinary grease emulsifies and disappears. The corrosion inhibitors are a real bonus for equipment that sits in damp storage between seasons.
It also carries heat well thanks to the lithium complex thickener, so it is not a one-trick grease. The honest downsides are cosmetic and minor, the deep red dye gets on everything and never fully scrubs off, and the feel is a touch less stringy than a dedicated tackifier grease. If your biggest enemy is water and rust, this is the one to reach for.
- Outstanding washout resistance for wet and marine conditions
- High temperature stability with a strong dropping point
- Corrosion inhibitors protect pins and bearings in damp storage
Pros: Excellent in standing water and washdown environments; Strong rust and corrosion protection; Stays consistent across a wide temperature range
Cons: Red dye stains hands and clothing; Slightly thinner feel than the tackiest options
4. Lucas Oil Red N Tacky Grease: Best Value
Red N Tacky is the workhorse cartridge you see in shops everywhere, and it delivers genuinely good performance for its qualitative value. The texture is smooth and stringy, so it grabs onto pins and pivots well and resists slinging better than plain general purpose grease. It also pumps easily, which matters when you are working through a long list of zerks on a tractor and a couple of implements by hand.
Because it uses a standard lithium thickener rather than lithium complex, its heat ceiling is lower, so we would not lean on it for the hottest wheel bearings on a heavily loaded trailer. Its water resistance is fine for general use but not in the same league as the marine-grade reds above. For everyday chassis and implement greasing where you want solid results without overthinking it, this is the smart pick.
- Smooth, stringy texture that grabs and holds on pivots
- Easy to pump in both hand and air-powered guns
- Reliable everyday protection for chassis and bearings
Pros: Great tack for the value; Pumps easily, even in cooler weather; Widely available and trusted
Cons: Standard lithium base has a lower heat ceiling; Less washout resistance than premium picks
5. Mobil 1 Synthetic Grease: Best Synthetic
If you farm in country that swings from hard winters to baking summers, Mobil 1 synthetic grease earns its place. The synthetic lithium complex base stays pumpable when conventional grease turns to a brick in the gun, and it holds its film at high temperature without bleeding out. That wide window makes it a strong choice for wheel bearings and high-stress points on equipment that works year-round.
It also tends to last longer between applications, which slowly pays back the higher value through fewer greasing cycles and longer bearing life. The catch is simply that it is more grease than many routine farm points need, on a slow, low-temperature pivot a conventional grease does the job just as well. Save the synthetic for the bearings that actually punish a lubricant.
- Synthetic base flows in deep cold and holds in high heat
- Extended service life reduces re-greasing frequency
- Strong load carrying for high-stress bearings
Pros: Excellent cold-weather pumpability; Wide operating temperature range; Long-lasting film cuts maintenance intervals
Cons: Premium grease for a premium application; Overkill for low-stress, low-temp points
6. Sta-Lube Moly-Graph Extreme Pressure Grease: Best for Extreme Pressure
Moly-Graph is the grease for the brutal, slow-moving joints, the loader and backhoe pins, u-joints, slip yokes, and bushings that see heavy shock and sliding rather than fast rotation. The molybdenum disulfide and graphite provide a solid sacrificial film that keeps protecting metal even when the oil film gets pounded out by impact. For extreme pressure points, that moly content is exactly what you want.
The flip side is that moly grease is generally not recommended for high-speed bearings, where it can interfere with the rolling action, so this is a targeted product rather than a do-everything tube. It is also black and messy, the kind of grease that finds your sleeves. Used where it belongs, on the heavy articulating pins of a farm, it is excellent and worth keeping a tube on the shelf.
- Moly and graphite add a sacrificial film for shock loads
- Extreme pressure additives protect slow heavy pins
- Good adhesion for u-joints and slip yokes
Pros: Excellent for high shock and sliding loads; Moly film protects when oil film is squeezed out; Strong on u-joints and pin-and-bushing joints
Cons: Moly is not ideal in high-speed bearings; Black grease is messy to handle
7. Super Lube 41160 Synthetic Grease with PTFE: Best Clean Running
Super Lube fills a different but real niche on a farm, the clean, lighter-duty points where you do not want black or red grease everywhere. Think latches, linkages, conveyor and grain handling components, and food-contact areas where the NSF food-grade rating matters. The synthetic base with PTFE gives smooth, low-friction operation and it stays translucent, so it will not stain a clean implement or product.
Be clear about what it is not, this is not a heavy shock-load or high-pin-pressure grease, and trying to use it on loader pins would be a mistake. Its strength is clean, consistent lubrication on lighter mechanisms that need to stay tidy and food safe. As a specialist that lives alongside your main heavy-duty grease, it is genuinely useful and rounds out a complete farm grease kit.
- PTFE adds low-friction protection on light and clean points
- Translucent and non-staining for tidy applications
- Wide temperature range with synthetic base oil
Pros: Clean, non-staining and food-grade rated; Low friction from PTFE particles; Resists hardening over time
Cons: Not built for heavy shock or high pin loads; Lighter duty than the lithium complex picks
Frequently Asked Questions
What NLGI grade of grease should I use for farm equipment?
For most farm equipment, an NLGI 2 grease is the standard, all-season choice and is what nearly every tractor and implement manual specifies for chassis points and bearings. It is firm enough to stay in joints under load but still pumpable through a normal grease gun. In very cold climates where grease stiffens, some operators drop to an NLGI 1 or a synthetic NLGI 2 for easier winter pumping, while extremely hot or high-speed bearings can occasionally call for a higher grade. When in doubt, follow the equipment manufacturer’s recommendation, but NLGI 2 covers the vast majority of points on a typical farm.
Can I mix different types of grease in the same fitting?
It is best to avoid mixing greases with different thickeners, because incompatible types can react and either harden or turn soupy, which destroys their ability to protect the bearing. Lithium and lithium complex greases are generally compatible with each other, but mixing them with calcium, polyurea, or clay-based greases can cause problems. If you are switching to a new grease, the safe practice is to pump fresh grease through the fitting until the old grease is purged out, then stick with one product per machine going forward. Standardizing on a single quality grease across your fleet avoids the issue entirely.
What does moly grease do and when should I use it?
Moly grease contains molybdenum disulfide, a solid lubricant that forms a sacrificial film on metal surfaces. That film keeps protecting parts even when shock or extreme pressure squeezes out the normal oil film, which makes moly grease ideal for slow, heavily loaded sliding joints like loader and backhoe pins, u-joints, slip yokes, and bushings. The catch is that moly is generally not recommended for high-speed rolling bearings, where the solid particles can interfere with smooth rotation. Use moly grease on the heavy articulating joints and a standard lithium complex grease on wheel bearings and faster-spinning points.
How often should I grease my tractor and implements?
A common rule is to grease chassis and implement fittings every eight to ten hours of operation, or at minimum daily during heavy seasonal use like haying or tillage. High-stress points such as loader pins and PTO joints may need greasing even more often, while sealed bearings need attention far less frequently. The honest answer is that re-greasing intervals depend on the point, the load, and the conditions, so always check your operator’s manual. When working in mud, water, or heavy dust, grease more often, because contamination shortens the life of any film no matter how good the product is.
Is water-resistant grease really necessary on a farm?
For most farms, yes, because so much equipment works and is stored in wet, muddy, and washdown conditions. Ordinary grease can emulsify when it meets water, turning milky and washing out of the joint, which leaves bare metal exposed to rust and wear. A grease with strong water washout resistance, typically a lithium complex or marine-rated product, holds its protective film through rain, mud, and pressure washing. If your equipment lives outdoors, sees the feedlot, or gets hosed down regularly, water resistance is among the most important properties you can choose.
