Nice looking unit. Usually the year is stamped on the serial number tag on all the ones I seen around here. We have a 77 and a 84. I will have to look at the s/n and see how close they are. I think 79 is when they changed them up a bit. What style levers does it have? Looks to me like a pre 79 but levers are a dead giveaway. I don't know the breakdown of years by s/n
Just a short search and I too have a hard time finding the serial number break down. What I did read was the early models used the AMC motor, later used IH. I will look in my 5000 manual and see if it gives me any information. Does yours still have the conditioner? Up this way most everyone pulled them off as the 4 foot window was too small all that hay to go through without a conditioner, well alone with. I do wish I could get one, just to see how much of a difference there really is
We were discussing engines on 4000 swathers on here last year. This is some info I found in the IH 4000 swather manual. Early 4000s used a 232 AMC engine, later ones used a 258 AMC engine, and some used a 225 slant 6 Chrysler industrial engine as well.
I mean the style of drive lever. The older ones have a 90 degree bend toward the operator and a straight slide back and forth. The later ones have a straight up and down lever with notches in the slot. Both have steering wheels. Throttle levers are also a bit different
Very impressive you got that beast loaded. I tried to load mine when I got it, wasn't going to happen with the ramps I had. Sooo, I drove it home one day, even in high speed, they are slllooowww. I did get alot of "salutes" on the highway. 40 miles, took about 4 hours. Nice looking machine. Draper or twin auger head?
Looks like a fairly clean unit. I don't know if I ever really seen one driven up on to a gooseneck before. Lifted on yep. We always use the transport to move them any distance. Makes sure you push those back wheels in on the trailer before you back up, otherwise it won't be fun lol
well i just backed it off this evening , had to wait on rain. i jacked the rear wheels up and turned them for reverse. the used creeper slow to get it off. all went good. also thought of taking a video. got a picture anyhow.
dont think there is any advantage , other than this would be like self propelled, plus it would need a hay conditioner, or crimper as we call them. mounted on it. these are basically used for grain cutting. with a haybine it is manufactured for cutting hay and does work better. i have an old 489 new holland haybine i use for hay. plus haybine has better reels and can go lower to the ground.
These have an advantage if being used to cut small grains. The draper head and lack of crimper or conditioner cause a lot less grain loss. That is the reason my Dad had the Owatonna self propelled windrowers when I was a kid. The same machine was used to cut alfalfa but also used to windrow oats before combining.
Finally got the swather put back together last night, cut 3 rounds aaand sheared the bolts off on the piece that mounts the head to the wobble box arm... What are the chances someone here knows the bolt size & length? Any tricks or advice on getting those bolts out? I'm hoping I can just weld a nut on and back them out, any reason that won't work? Any advice would be great, thanks.
Looks like the serrations are pretty wore, if they are it is hard to hold. My parts book is at the shop so can not look up the size at the moment but that should not be that hard to figure out. Seems like 5/8 x 2, 2 1/2 range off top of head. I use grade 8 bolts and harden washers and torque to 200 foot pounds which does help hold them.
Seems like most of the time when the bolts break, but not necessarily all the time, it is because something is loose. Splines, ball joint, mounts. Just check it over good. Maybe the bolts just gave up.
5/8x2 is what I measured on ours with a lock and flat washer. Used to break them once in a while but rebuilt the wobble box and no more trouble. Check to see if there is any play in the pitman arm. Turn things by hand and see. Might be time. Are the bolts tight that hold the wobblebox down? Also like was said the serrations on the arm look wore. Did you change the block on the head that attaches to the arm too?
Pretty sure the wobble boxes on both the IH 4000 and the MacDon-based swathers in the later 1980s were JD units. The first MacDon combine draper heads used JD wobble boxes as well until MacDon developed their own box later on.
JD wobble boxes are MacDon designed and manufactured, Dad sold a good amount of MacDon 4000 MoCos in the early 2000s (similar in market place as a 492 NH) so I have heard the spiel from the company rep, leave it to a Canadian company to market there product to a big company like JD and still be able to sell it as there own with the same casting with JD markings and sell it to IH as well the same way, I often wondered if the IH 4000 swather was a MacDon, I was quite young when Grampy replaced his IH 4000 with a MacDon 7000, but always thought the machines looked similar, so with this newfound information I think MacDon had a part in the IH4000
I remember seeing wobble boxes cast JD or MD on new MacDon machines that were painted black and eventually showed green paint underneath the black MacDon paint, also remember in later years getting parts for a JD machine and the box came black marked MD
