Sickle Mower
What exactly is the function of the gag lever on a sickle mower?

Re: Sickle Mower
Without that mechanism, when you try to raise the cutter bar the outer end would remain on the ground.

Re: Sickle Mower
So I have this issue with the C-22. Everything is hooked up and connected and it runs. But man o man it shakes. Looking at it closer, the rear pulley for the lower drive/flywheel shaft has about 1/2" front to back play in it. The PTO pulley (with a pin through the pulley and PTO shaft) is about 1/2" out of alignment (to the front) of the lower drive pulley so when running I can look down and see the lower drive pulley going front to back that 1/2" which is a big contributor to the shake. I saw Matt and Stacey's videos and while they say there is some vibration....it is nothing like I have.
Is there a way for me to move that lower drive pulley toward the front to overcome the play in it and seat it to align the pulleys and reduce the vibration? Thank you. John

Re: Sickle Mower
Can’t remember the sizes, but machined bushings(washers) take up that slack. Lot of moving parts on these, so a lot of places for vibration to develop. Peruse the manual to get a better understanding. There are bushings inside the main shaft at each end that need checked. Bearing on the Pittman needs checked. Register needs to be correct(see manual). And blade alignment needs to be 90 degrees to the shaft. That’s taking into consideration the backward pressure exerted on the bar as you’re cutting.

Re: Sickle Mower
So i would need to pull the pulley and drive shaft out to put in the spacer washers. I presume there is a way to remove the pitman flywheel so I can pull the shaft out from behind. The manual has 2 sentences where a paragraph is needed!

Re: Sickle Mower
No, don’t remove the flywheel. Remove the rear pulley and shaft will slide out the front. Trust me, you don’t want to remove the flywheel
Edit: threads on the pulley are reverse threads. Clockwise to loosen. Same for front bearing nut

Re: Sickle Mower
I bet that pulley is going to be a dog to get off. I suppose I have to jam the flywheel up front to work on the pulley in the back.

Re: Sickle Mower
They can be tough, but usually not too bad. Impact is best way to go. Otherwise, yes, jam the flywheel.

Re: Sickle Mower
Again, manual doesn't mention....does the pulley unscrew from the flywheel shaft or is it pinned?

Re: Sickle Mower
The pulley below the PTO is actually called the FLYWHEEL PULLEY. Here is the manual on the Mower:

And on page 14 it is part #2, and paragraph #2 describes the washers used.

Re: Sickle Mower
It unscrews. No pin. And Dale is correct , of course, since there are two pulleys in the system. To differentiate between flywheel pulley and pto pulley. Pto pulley has a pin(usually cotter key) and a bolt

Re: Sickle Mower
And if I remember correctly, it is pretty easy to find a place forward to put a "wedge" in between the bottom of the right side of the hanger bracket and the cutout/notch on the flywheel when rotated into position. You can see the area I refer to in Illustration #14, at the far right at the flywheel:

NOTE: You block the rotation one direction on the bottom right, but when reinstalling, you jam it on the other side (or vice versa!)...can't really remember which side for ON and which side for OFF...I don't even own one!!!
