sickle bar again

Folks

Please forgive my ignorance as I don't know too much about sickle bar mowers. I recently bought a used 3 pt sickle bar out of the classifieds, however I can not find any tag on it to say that make or model it is. So here is what I do know about the mower it appears that the original color was green and looking at some of the parts on the machine it list a number on some of the parts and they all start with "MT". On the cutting bar all the guards are CASE. Second question I have is when I go to raise the mower to over an obstacle with the bar down I have to shut done the machine. I have to raise the 3 pt all the way up to get the end of the bar only about a foot off the ground. So my question is, is it normal to have to raise the whole machine that high to get the end of the cutting bar off the ground? Thank you for your time and all help is greatly appreciated. I would post a picture, but I am not sure how.

Best Regards
Jason Sunderland

As I look at your mower I see a shiny chain by the long heavy spring. I suggest that when mowing you raise the three point to run the PTO shaft somewhat level. At that position the chain should be fastened somewhere on the tractor to a stationary point that does not raise. Maybe drawbar or on the axle somewhere for some. You do not want much slack in the chain. If you look at where the chain is fastened on the mower and follow that part toward the cutter bar you will see how having that chain fastened will cause the outer end of cutter bar to raise faster and not have to raise the mower all the way up. I know I am clear as mud but as you look at the parts mentioned I believe you will understand how it should work. The tricky part is getting that chain the right lenght to do th job without having it too short wich could cause something to break.

I forgot to mention that with a belt drive you have somewhat of a safety "fuse" factor. My experience indicates that the biggest factor that breaks pitmans is that the outer end of the cutter bar drags to far back and the sickle is not lined up with the pitman when mowing. Non of the old timers that I learned from ever mentioned that a pitman is a "fuse" but a broken pitman was a sign that something was out of line. They all talked about belt tension not being too tight so slippage could occour if needed.

Jason try emailing me a picture of your mower, your yahoo freebie has used up it's bandwidth. When you raise the mower the end of the bar shound come up a couple feet. There should be an adjustment to change it just a little. If I could see a picture of the linkage I could probibly explain it to you. But yeah, most mowers don't raise part way very well, they are either clear up or riding on the shoes.

the bar should have a lift all to it's own. you should beable to raise the bar to turn around, etc. with out having to raise the three point. when you not cutting and in transport the bar should either stand up or fold over also. i would say your not seeing something or your missing parts.

There is a rod that it threaded on the end with a nut that goes through the bar to hold it up to transport it. I was more concerned about going over obstacles, such as a groundhog/woodchuck hole, in the field where you only need to raise the bar enough to clear a small mound of dirt. To me the thing to do it that situation to raise the 3 pt enough to clear it and not get off and raise the cutting bar to move a few feet and get back off and lower it back down.

On my MF 32 you have to raise the 3 point to raise the mower. Maybe you are thinking about a semi-mounted.

Is this a belt driven (pitmanless) or does it have a wooden pitman arm that runs the knife?

It has a pitman arm, although someone replaced the wooden one with an aluminum one.

You might want to think about going back to a wooden pitman stick. It"s supposed to act like a "fuse". The system is designed so that the wood pitman breaks before anything more important and costly can break in the event you encounter an obstacle that can"t or shouldn"t be cut (a steel T-bar fence post comes to mind...don"t ask). An aluminum pitman will not break or need replacing as often as a wooden one, but you lose the safety valve factor.

Hi , Someone on this forum once said that if you had a spare pitman stick in the shop then the one that's on the mower will never break . Well , I'm here to disprove that theory ! Mine broke about 1/2 hr into mowing yesterday . And I didn't hit anything ! OK , To be honest it was probably 30 years old :] Still took about an hour to get back to the house and change it and get back out to the field .

If your mower is green could it be John Deere or Oliver ? Your pictures didn't come thru , for me at least . Does it look like there's a place near the hinge of the inner shoe where a cylinder can be attached or maybe a cable and pulley system to your left lift link ? I have a Minnie- Moline that uses the cable to lift the bar end when the 3-point is raised Via a link attached to the left side of the mower that goes under the lift arm from the tractor . As the mower goes up it rotates the link down which pulls the cable making it shorter which raises the inner shoe and the bar end . Clear as mud ? If it doesn't have a unused pully or guide of some sort you probably don't have that system . Good luck with it ...Randy
