Alimites on Kubota 326?

I have been looking in my book for where they are at?
I found the ones on the deck... How do you get to the ones on the universal joints are there any tricks?
Book shows there are 2 under seat by throttle. I can't find these 2.
I don't find any on the frame.. Guess I'm getting old
any Ideals on how and where to find these

There a three on the shaft that drives the deck. I rotate the blades until the front fitting is straight up. Grease the front u-joint and the slip joint. Raise the seat and the third should be pointing up under the transmission filter. The driveshaft between the engine and the transmission also has three fittings. The front u-joint fitting is the second one under the seat and is accessed by lifting the plastic cover in front of the radiator. What I do is rotate the shaft until all three fittings are pointed straight down and lube them from below.
