PTO shaft greasing? It depends.
Firstly it depends on the condition of the shaft, whether it has been overgreased and split the seals on the spider cups or not.
Secondly it depends on the angle they work at. A straight running shaft will require greasing less often than otherwise.
Thirdly it depends on the average torque transmitted relative to shaft size.
Make of that what you will but consider that there are many shafts that don’t have nipples and others that last decades and 10,000 hours plus with greasing only annually, like my land cruiser’s propshaft. Examples that generally don’t have nipples are tractor front axles.
Sliding parts of shafts again depend on many of the listed variables, but the aim is to keep the wet to allow easy telescoping, even under load. If it doesn’t telescope then it needs less attention.

Yes, or you can get gun fillers. Most guns have filling nipples on them these days. Some people might not even be aware of what the nipple is for.

Had a gun filler from spaldings about 20 years ago, a real pain to use and slower than syringing it in, so scrapped after about 10 uses, its only good thing is you could "top up" the guns.

I’ve had one for twenty years and not had a problem. Cold weather slows it down, but as with most things, there’s a knack to it.
I'm sure more spiders die as a result of seized shaft sections than from not being greased themselves.
Changed some non-greasable prop shaft hardy spicers on Matbro a while back that have done 5000 hrs at least, and then only because shaft had to come out.

My dad would never buy cartridges ,allways a bucket of grease.remember in the 70s/80s his main man would fill the gun from the bucket by hand,then grease would end up on tractor door handles,steering wheel and gear knobs,light switches and everything else he touched.wish the chap was still about but very annoying at the time

I bought a 'speedy ' grease gun that you just push the cartridges into the head and place an easily losable plastic plunger into the base of the cartridge. The theory is that as you pump it draws the grease from the cartridge. THINK AGAIN!, Mr. Grease gun designer. If the weather is cold you end up pushing the plastic plunger up the cartridge with a piece of threaded rod or similar, this is only achievable if you have three hands. No prizes for guessing if I will buy another.

place i started work on years ago hand a gun filler think made it also was for doing tracks on dozers
any how worked great
but use cartridges now days just eazer and can have diffrent types of grease hanging about

Couple of days?.. 10 uses would be more like 6 months as some of the guns didnt have a filler on, and because of that i soon didnt bother with it.Scrapped it after only a couple of days use

Once a week here

Obviously depends what it's doing and what it is. Hay making kit will probably once a week or every 4-5 days if I remember/have time to do it properly, including the baler.
Hedge trimmer once a week. Trailer, when I remember to do it, had a bit of a mare trying to unblock a few last week, need to remember to keep doing them. Digger once a week or when it starts creak.... Flail topper once a week or every few days. Tractor front suspension, ram ends, swivels maybe every 2 weeks. I don't think I've left that too long between greasing as it's all still free and working. Rear linkage once a week or every few days.
Don't think I've over done anything as it's all still working. Think it's pretty well common sense, don't see the need to do some things every 8 hours myself.

Should try Lubeshuttle, works every time.

And a plastic plunger already in each cartridge.

We use cartridges but when I first started it was buckets, so just telling someone how to fill out of a bucket the easy way
Think that needs editing.

I remember a guy from Howard's (Howard's as in Howard Rotavator) telling me that the best lubricant for P.T.O. shafts was molybdenum disulphide grease.

The frequency of greasing should only really depends on the rate of loss of grease from the assembly assuming reasonably good materials involved. Two reasons, firstly with higher loss units the first bit of grease is used to clean the assembly as, if grease goes out quickly, then dirt comes in. Older bearings of this type should be greased until clean grease appears.
Newer fittings with better seals naturally use less and to over grease can compromise the seals long term so need much less grease.
For the last forty or fifty years grease had been good enough to not need replacing in bearings unless it is lost so I can't see how you need special grease in normal circumstances. We all have sealed bearings that have worked reliably for many many year without new grease and if you look at how little grease is in a bearing it is amazing.
I must say I prefer the bulk transfer gun filling as I always make more of a mess with a cartridge as my guns are not really designed for them.
