Greasing isn't really necessary. The swivel aren't under any constant load or are swiveled that often.
You can use a spray white grease and give the swivels a good shot. I've done this with a very old (no idea of the brand, but wouldn't be surprised if it's older then I am) rear blade I've had for years...still swivels.
If these implements are left outside, it probably wouldn't hurt to spray them occasionally (prevent rust).
Good evening, Roy --
I just bought a CountyLine 7' landscape rake (made for TSC by King Kutter, and same as King Kutter) this past Friday. Since that time, I have used it approximately 12-15 hours from Friday through Sunday and I would respectfully disagree on both the lubrication and the amount that it is swiveled!
The first couple of hours (before greasing) it was a pain in the butt -- hard to move positions and the "securing pin" had to be hammered out each time because it was binding -- so much so that I was considering welding a new one with a "T" on top. I finally took a break, put the tractor in the stable, jacked up the rake on the swivel with a hydraulic jack and coated it *liberally* with lithium grease (tube type), then let the jack down so the swivel would "take in the grease. Did this on both sides, also coated the "adjustment plate" liberally on both sides, and coated the securing pin liberally with lithium grease.
Difference in "performance" is phenomenal -- the rake adjusts with ease and, no matter how rough the most-recent use, the securing pin never binds -- can be easily pulled out by hand.
You are probably wondering why I spent so much time with the rake. We have a horse stables and here were the things that I did with the landscape rake:
1. We just had a large dressage arena (~60' x 200' + 10' borders) leveled by a grader two weeks ago. Lots of loose rocks (generally 3" or less) floated to the surface. Spent about 4-5 hours "de-rocking" and breaking up soil clods and moving excess to a storage area. Ended up with four pretty large mounds of rock-filled dirt.
2. Grader also graded the roads on the property and I raked the roads thoroughly to ensure more uniformity of remaining rocks (primarily pea gravel-sized now).
3. Moved "oversized rocks" (mixed with some pea gravel) from roads to stable to put in parking lot.
4. Raked some accumulated leaves from under oak trees.
Great implement, should have had it several years ago.
By the way, congratulations on the new 4400!
