Where to Grease the 3 Point Hitch Linkage \u2014 and How Often<\/h2>\n

The 3 point hitch linkage contains more grease-able pivot points than most tractor operators realise \u2014 and most of them are under-greased in practice. The lower link pivot pins, the rock shaft arm connections, the lift rod pivot, the top link ball joints, the levelling box pivot, and the lift arm-to-check-chain connection points all carry significant loads and require regular lubrication to prevent fretting corrosion and premature wear. A hitch that is not greased regularly develops play at each pivot point \u2014 play that multiplies through the linkage geometry to produce excessive implement movement under draft load.<\/p>\n

This guide identifies every grease point on a typical rear 3 point hitch, specifies the correct grease type, and gives a practical lubrication schedule that matches how the hitch is actually used in the field.<\/p>\n

\"where<\/p>\n
The 3 point hitch linkage has up to 14 grease-able pivot points \u2014 under-greasing any of them produces fretting corrosion that develops into seized or worn pins within two seasons.<\/div>\n<\/div>\n

Complete Grease Point Map for a Rear 3 Point Hitch<\/h2>\n
\n
\n
1<\/div>\n
\n
Lower link rear pivot pins (\u00d72)<\/div>\n

The pivot pins where the lower links attach to the rear axle housing. These carry the full implement draft load and are the most heavily loaded pivot points in the entire linkage. Grease nipple typically located on the pin housing \u2014 one nipple per side. Grease at every 50-hour service interval during the season.<\/p>\n<\/div>\n<\/div>\n

\n
2<\/div>\n
\n
Lower link front pivot (\u00d72)<\/div>\n

On some tractors the lower link pivots forward to a point on the rear axle housing rather than straight back. This front pivot also needs greasing. Location varies by tractor model \u2014 check the tractor lubrication chart for the precise location on your machine.<\/p>\n<\/div>\n<\/div>\n

\n
3<\/div>\n
\n
Lift arm-to-lower link connection pin (\u00d72)<\/div>\n

The pin connecting the lower link to the lift arm or lift rod. This pin cycles through a significant arc on every lift-and-lower operation. Grease nipple on the pin housing or through a drilling in the pin itself. Grease every 50 hours or weekly during heavy-use periods.<\/p>\n<\/div>\n<\/div>\n

\n
4<\/div>\n
\n
Levelling box pivot (\u00d71)<\/div>\n

The levelling box \u2014 or right-hand link \u2014 allows independent length adjustment of one lower link for implement levelling. Its pivot points at both ends require greasing. Often overlooked because it is less accessible than the main lower link pivots. Grease every 100 hours or at seasonal service.<\/p>\n<\/div>\n<\/div>\n

\n
5<\/div>\n
\n
Top link ball joints (\u00d72)<\/div>\n

The ball-and-socket joints at each end of the top link carry significant compressive load during draft work and tension during mowing or levelling. Grease nipples are usually present on the ball housing \u2014 apply grease until the old grease is displaced from the socket seal. Grease every 50 hours during heavy draft work.<\/p>\n<\/div>\n<\/div>\n

\n
6<\/div>\n
\n
Lower link ball ends (\u00d72)<\/div>\n

Ball ends without a grease nipple rely on manual application of grease to the ball surface. Remove the implement, clean the ball end, and apply a coating of multipurpose grease at the start of each season and after any extended storage period. Ball ends with grease nipples should be greased every 100 hours.<\/p>\n<\/div>\n<\/div>\n

\n
7<\/div>\n
\n
Check chain anchor pins (\u00d72)<\/div>\n

The pivot points where the check chain anchors to the rear axle housing experience continuous fretting as the implement moves laterally in the field. Grease these at the seasonal service and mid-season if operating in muddy or wet conditions that wash grease from the pins.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Correct Grease Type for 3 Point Hitch Pivots<\/h2>\n

Use NLGI Grade 2 multipurpose lithium-complex grease or calcium-complex grease for all 3 point hitch pivot points. These greases provide adequate load-carrying capacity for the draft loads the hitch experiences, good water resistance for outdoor use, and temperature stability from cold morning starts through heat generated during extended operation. Do not use chassis grease (NLGI Grade 1) for hitch pivots \u2014 it is too soft and will be displaced from heavily loaded pivot pin-bushing interfaces under draft load. Do not use NLGI Grade 3 grease in cold climates \u2014 it does not flow adequately from grease gun to nipple at low temperatures.<\/p>\n

\nHow much grease should I apply to each hitch pivot nipple?+<\/span><\/summary>\n
Apply grease until fresh grease appears at the seal or edge of the bushing \u2014 typically 2\u20134 pump strokes from a standard hand-operated grease gun per nipple. Applying more than this does not increase protection and wastes grease. If fresh grease does not appear after 5\u20136 pumps, the nipple may be blocked \u2014 check with a nipple tester or replace the grease nipple before the next service.<\/div>\n<\/details>\n
\nCan I use WD-40 or penetrating oil instead of grease on hitch pivot pins?+<\/span><\/summary>\n
No \u2014 penetrating oils like WD-40 are not lubricants for loaded pivot pins. They displace moisture and free seized components, but they evaporate rapidly and leave no load-carrying film. Using penetrating oil in place of grease on hitch pivots provides no sustained lubrication and may actually accelerate wear by washing away any remaining grease from the pin surface. Use these products only to free a seized pin before cleaning and applying proper grease.<\/div>\n<\/details>\n
