Thanks for helping. It's a front mount 47 inch blower I bought with a 2018 tractor in early 2019. The manual shows a center zerk on the drive shaft, but doesn't show how to get to it. They have the plastic shroud removed on the illustration in the manual. I have never taken the blower off of the machine since I only use it for snow removal here in the mountains.A photo might help. Model of blower? Front or 3 point mount? I have the front mount 47" blower and I don't have any center zerk on my drive shaft.
Give us a bit more info and we will be able to solve your issue.

You have to rotate the joints bending the connection for a few of them. What year is the blower tractor? Just don't put in to much grease, otherwise they can lock the joints on certain years. Then you must remove the zerk to let out the excess grease to free it up. Usually happens at a double cardan joint, not on a regular universal.Very good. I'll try going to the rear PTO setting and rotating the snow blower by hand to see if I see the center Zerk under the plastic. I've never had the front mount 47 inch snow blower removed so I am trying to grease it on the tractor if possible. I did remove the drive shaft from the PTO to get to the end zeros. I agree about the small diameter coupler. I tried one of the locking type and it was too big for most of the drive train zerk areas.
Hi, The snowblower was delivered on my tractor. It's a 2018 that was delivered early in 2019. The snow blower is a front mount 47 inch. Thanks for the tip about not putting in too much grease!You have to rotate the joints bending the connection for a few of them. What year is the blower tractor?

Steve - I never k ee this...and it seems the last 3 years my snowblower seems to girate a bit when it is in the 'UP' position.....I wonder if that is why?If you remove the drive shaft from the tractor and the shaft from the blower it is much easier to grease them. Now if you do remove them when you put them back make sure you time the u-joints or you may induce a vibration when running the blower. If you have run the blower and not had a vibration problem they are probably timed. To time you have 4 universals 2 on each shaft. On each joint one u-joint side end is welded to the shaft. Call this the fixed half of the joint. Put the the shaft on the tractor first. Then when you put the shaft on the blower make sure the fixed ends of the two shafts are at 90 degrees from each other.

Thanks so much, Steve! I will check out the video....I am so glad you posted this. I just added a 60 inch plow to my arsenal and have that loaded on right now to try it on our next snow....but have the main drive shaft installed should I want or need to switch to my blower for a heavier snow.....I will be sure to get the shafts properly aligned if I swap back to my blower. Thanks again! Have a great Wednesday!Yes that is correct. The U-joint part that is welded to the drive shafts should be at 90* to each other.
If you notice the U-joints on either shaft are welded 90* to each other to prevent vibration when under power. And the vibration gets worse as the angle between the two d-hafts increases. So in the up position the vibration (your wobble) would be more noticeable. There is a video on the i-net somewhere that shows this. If I can find it I'll post a link.
