hubs and zerks

why dont front hubs have grease zerks?
seems i have to pack the bearings by hand.

They don't have zerks because they don't need them and shouldn't have them. If the seals are good, the grease in the hubs will last a long time, especially on something slow like a tractor. They shouldn't have them because people then tend to put in too much and the wrong kind of grease. Go ahead and grease your wooden boxings and your simple cast iron bearings because they need it. Leave your tractor hubs alone.

Depends on the model. The hubs on the front wheels of my 3 cylinder '73 4000 have grease fittings, as do the barrels of the spindles. I hit them with grease once a year till I see clean grease coming out around edges and clean off all of the old dirty grease that ends up being pushed away form the joint. I use the same moly grease in those that I use in all of the pivot points of the loader, backhoe, steering and hydro pedal linkage on my Kubota. The loader and backhoe get grease very 10 hours as per the manual and the rest of the Kubota gets grease once a year, which is more often in terms of hours than the book recommends, but I'd rather spend a little on grease every year than a lot on replacing parts down the road.
