Does anyone know of a stie on the net where a person can find adjustments for a Ford sickle bar? Also for any trouble shooting or maybe someone can help me here. When mowing the tip end keeps clogging with the mowed grass/weeds. I have to stop every 10 ft or so to remove the cut grass. Blades are sharp so I don't know what to do..... Many thanks

When I posted the sickle bar information this morning I goofed. I guess that's what I get when I try to think after working all night. Here is the CORRECT information.

I went to one of my old mower manuals and scanned the following information. This tells it better than I can. Please click on the ling below to view it.

Again, sorry for my error.

Houndman, Thanks for the neat post, but now I'm REALLY confused! The scan you posted says illustration no. 1 is correct and no. 2 is incorrect. I have always thought it was the other way and my post stated that. We always set ours like illustration no. 2 and they worked just fine. Maybe the timing is not as critical as I have been thinking it is. Next time I run my JD #5, I'm going to play with this a bit and see what happens.

I know what you mean about being confused about the informaton. Later today I'm going to go through a few of my other manuals and see what they say. Please look back here later today. If I find anything new, I will scan it and post it here.

Minnesota equipment was made at the state prision at Stillwater, Minn. Who knows, one of the "guest" that was there at the time may of decided to have a bit of fun by changing a few things around in the manual.

Houndman,
I studied my manual for my JD #5 mower and it definitely shows the sickle section tips in the exact center of the guards (in other words out of sight within the guards) for "correct" alignment at either end of the pitman stroke. As I mentioned before, that is the way we always set it up and it has worked just fine. Your comment about the inmates maybe mixing up things in the Minnesota manual may be very correct!

To see if the mower is in need of adjustment, have the sickle bar lowered and the pitman turned as far as it goes to the out position. If the points of the knives on the sickle are centered between the guards, it is in time and doesn't need to be regulated. As for how to adjust it if they are not centered, I can't be of any help. I only know how to do the John Deere and McCormick horse drawn mowers.

I would also turn the pitman by hand to watch the knife movement between the guards. Make sure the movement is even for all the knives.

I don't know if Ford mowers had these or not but make sure that the guard ledger plate isn't missing from the inside of the guards. This may also cause your problem.

Hope this helps.

The entry about sickle sections being "between the guard points at the end of a stroke" is not correct. To get the full cut of each side of each section, the section-points must be in exactly the center of the guards themselves, in other words you can't see the tips of the sections when the sickle is at either end of its stroke.

Is the ledger plate still in the end shoe? Is it tight? Does it still have a sharp edge or is it rounded off? They are a real pain to change, but make a big difference on how much trouble you have mowing. The previous posts about the double pointed section are right on, but it still needs something to cut against. It also helps to put a hold down finger as close to the end as possible, and sharpen the point of the end shoe.

If you are mowing grass then you MUST HAVE smooth edged blades. The serrated edged blades grab the grass and pull it through the knives.

The problem you have is probably because the knife is too far away from the guard, the other part that makes the sickle cut...if grass/weeds gets caught in between the tip of the knife and the front of the inside of the guard, this is probably your problem...the knife has to be close to the guard to make it cut...if this is your problem, the knife may be bent up...either bend the knife back down or just replace it...also make sure that the guard isn't bent...

Do you have a regular knife section on the tip or a double knife. They are a major part of eliminating them. Most farm supply stores will have them if the sell other mower parts. Its referred to as the double knife section.

The bar and knives are all the same. What does the double knife look like?

Thanks

The back edge has the 2 rivet holes, the front side has 2 points on it instead of one. Ask the head of the farm supply section of the store. Common deal, usual solution.
