john deere 1209 wobble box

[olgentdc]

The haybine gearbox has a 7/8 pin sticking thru the side ,,.. I can push it back in and the the gear box will roll over as normal ,, however this pin has no visible way to stay put in home position ,,. 2 things i need ,,. a parts blow up of the gearbox ,,,. And then , if anyone familiar with the gearbox can tell me if this pin has actually wore thru and made a perfectly machined hole or if the oblong slot is factory ? Many Thanks and God Bless our Soldiers who gave their All ..

Parts diagrams are available for free from John Deere. Just Google 'Deere parts books' and follow the appropriate links. Good luck with it. The wobble box was one of the weak points of the 1209. I never had any patience for the 1209. The early ones especially were prone to wobble box failures. Not really the fault of the wobble box: the plate they mounted to was too weak and would fatigue/bend over time, and when run like this it would put a lot of strain on the box which would eventually start spitting bearings. Best purchase I ever bought was an IH 990 haybine for $270 a couple of years ago. It's older than the 1209 I had, was far more beaten up than the 1209, but it could cut circles around the 1209. It was a good day when I took the 1209 to the scrappers. Wish I'd saved the wobble box - I would have given it to you happily.

Can you post pics? I can't remember off the top of my head. I disagree with Daniel. I ran a 1209 and then two 1219's for prolly 25 years and they were excellent machines. I loved them.

I wish i could post pics ,,.. But I do thank You and DanielW , I was able to go online and see the Wobble box case ,,.. Mine has a oblong hole where the yoke pin has worn plum thru making a wonderfully machined factory looking hole ,,.. ... That hole is not evident in the parts blowup ...,, Therefore it is safe to believe that this gear box is ready for remelt at the foundry ,,...i do however have a jd combine gear box that has a larger flywheel and could with some creativeness be made to run.. i need to swap pullys and counterweights and a few other particulars plus beef it up to the mounting brackets

I know the 1219 gearbox would fit. Probably the 1207 (7ft version) also. I bet you could find one at a boneyard. I'll look, but I don't think our gearbox is still around.

Call around. I took a look online....there are plenty of salvage yards with the 1209 or 1219. Might find a gearbox reasonable.

I was employed at JD dealership when 1209 Mo-Co's were introduced. Yes there were a few sickle drive(Wobble box) failures but I don't remember that it was a major problem. Now if you want to discuss the Mo-CO predecessors 480,483 & 485 with similar wobble boxes was a total different story. Only pin I can envision that could be protruding out side of gearbox is item16 BUT that pin moves back & forth with shaft that drives sickle. If wobble box mounting bracket ever requires any welding I suggest to scrap Mo-co. Many welders have attempted to weld cracks in that bracket with poor success rate. Wobble box part # is AE34800 https://www.tractorpartsasap.com/wobble-box-used-john-deere-ae34800-404356.html

I rebuilt mine on my 1207. Deere used that box combines too. I have a spare from a parts 1207 but not sure I'd want to part with it. If it's the yoke pin that wore through you'd have to get another case and ring. Those pins are pressed in. I tried to remove them with the pull screw provided and gave up, really tight so I left it alone. I have a scan of the service manual but it's too large to attach here. I'll try to PM it but will need your email if it doesn't work.

Can't say about the 07 models. our 1219 is still going cut hay with it every year sinc e bought new. IT does need some regular maintenece each years sections ,guards and wear plates or hold downs as required. never have had a wobble box problem yet . I don't really push it hard mowing might or not be the reason for no issues yet. used to cut about 2-300 acres per year with the 2nd and 3rd cutting in there . Now it just has to cut about 20 acres plus the later cuttings so maybe 60 acres total. Most years just the 2 cuttings and that's only 40acres.

True, the 1219 (and even the later 1209's) were a different animal than the early 1209's before the serial number break. 1219's had the beefed-up wobble box mount, 5 bar reels for smoother and slightly faster crop flow, and an improved vulcanization process (and slightly different chevron pattern) for the rolls. Still not my favourite mocos (just personal preference) but very respectable. The early 1209's before the serial number break were a different story: 4 MPH max speed, sluggish and slow, the unnecessarily heavy and cumbersome head made it 'lumber' around the field (especially rough fields), and lots of failures due to the wobble mount flexing or cracking. Most of the later 1209's had the same improvements.
