Well, I done it - broke the bar that the knives are attached to - the one with all the holes and rivets. Tried to weld it - lasted another round and a half. So now I need a new one. Questions: Can I get just the perforated bar, attach my own knives? Is this a generic part - can I get it at Tractor Supply? Should I go down the road to the machine shop, pick up a new bar and a handful of drills, and make my own? My local JD dealer is far from local, and it'll cost me a day just to get the part, if he has one, not to mention the cost!

 UPDATE in reply to RayP(MI), 08-04-2004 19:59:34  
Have checked around and apparently there are not aftermarket replacements available. JD has a complete unit - head, bar and blades available for about $115. Also have a bar only, add your own blades and head, for under $30. I think the reason for my double failure was that I was trying to cut hay that was far too tough. Too much undergrowth of fine grass, could only mow a few feet before the bar would plug up, and trip the bar release. Also was running into lots of ground mole mounds with rocks in them. Ordered the complete unit, as I have to get the hay done as soon's I can. Next winter, I think I'll get a piece of strap iron and make my own!

I hope you checked with Mr Webb at sickle works. Complete bolt on with head for around $75

Went to his website - couldn't make much of it. Got the replacement bar today, complete with head end, (new needle bearing design), and complete new blades. Had to modify hold down, 'cause head was a little longer, but was out mowing today. Also replaced a bunch of ledger plates. Working good, but it still was struggle in heavy downed stuff. Don't know what I'm going to do with that - maybe the bush-hog. That doesn't do a very good job either!

Lower the runners on the inner and outer shoes, to raise the cutterbar a bit out of the debris.

Already at highest setting. Dad-blamed ground moles, anyway!

A broken sickle is oftentimes a symptom of other problems with the mower. Possible alignment or worn hold-downs for the sickle head or a dull knife. I have welded many and have not had too much success until other problems are remedied. One way to make a fair remedy is to remove sections from the end which broke and rivet the sickle head to that end and then weld the broken piece to the outer end where there is less force.

I took mine to a professional welder, and for $10 it lasted me about 10 or so years, ( until I bought the NH488 ).

I have seen others have similar success. I have also seen several failures, but I think that is because they were not as good at welding as they thought they were. I'd suggest trying a "welder by trade"....you'll get a stronger weld that just might be satisfactory.

Many places sell replacement sickle bars. You can buy with or without the driver head. I personally wouldn't fool with getting anything but a bar with new sickles bolted (or rivited if you must) on it as a complete unit. Can get a 7' sickle bar with head for about $75 for mt Ford mower. The local ag supply places might have one; likely can order one; many of the popular mail order places have them.

It is possible to get a 4-hole sickle section, drill the bar, and bolt in the section to repair what you have. Many new longer bars are made of 9' bolted together sections like this. (Bolts - steel. Mallable rivots don't take it....) But, since it wasn't designed this way, more of a band-ade for your old bar than a real fix.
