Big Bud guy Posted December 30, 2025 Posted December 30, 2025 10 minutes ago, lotsaIHCs said: For efficiency, spur gears (parallel shafts) and straight bevel gears (intersecting shafts, like spur but angled) are both very high (94-98%), but spiral bevel gears often edge them out (95-99%) due to smoother, continuous tooth contact, while hypoid gears are slightly lower (80-95%), That was taken from the web. So take it for what its worth. The 15-30 was a bit heavier tractor that pulled a few hundred pounds more at the draw bar than the D. Ok. As for shifting an IH, the older ones were a basic 1 lever H pattern. The 66 style was simple. Pick your gear wih 1 lever. Then use the other to chose hi or lo or reverse. 90 percent of the time, once I pick my gear I don't change it again. I just use the other lever to switch between forward and reverse. On a 8 speed synchro you use one lever to pick your gear. Thats it. You can even use that same lever to go into reverse. I don't know what the gripe is if you are leaving the tractor in one gear all day long. If you are using 3-4 different gears shifting 400 times a day or more then you might have a point. Quote

Then within easy reach is the ole shift-on-the-fly 2 or 3 speed. The gold standard of that era of time. Quote

Never have been around an Oliver of that vintage Quote

Never have been around an Oliver of that vintage Oliver had a unique but actual nice gear pattern. They could be equipped with a two speed between clutch and transmission. The two speed was a planetary with a sprague clutch. So a cross of IH and JD two speed. The Oliver had a double H shift pattern. A reverse and three speed H up towards dash then back to neutral and you actually moved lever down enough for another H shift pattern. Once you got used to it it was very slick. My Dad ran Put puts , IH tractors and quadrangle transmissions. We bought an old Oliver just to have our own loader tractor in 1998 and he just fussed about that shift lever. He actually ran Oliver’s before that but he would just gripe about the Oliver because he didn’t like it. But at times it was only loader tractor working as he was getting older and very destructive with his equipment. 1 Quote

The only problem I ever had with that transmission is the gap between 5th and 6th is too big, like I would have wanted to leave it in a 5.5th gear all day long. 1 Quote
OFFTHEFARM Posted December 31, 2025 Posted December 31, 2025 3 hours ago, Big Bud guy said: I farm in an area that averages about 12” precip and what is called a prairie pothole region. Dry land alfalfa is a crapshoot on a good year. Some of my fields are in the hills/rolling terrain and on a poor year the tops of hills the hay might only be 6” tall and in any low spots and spots trying to go alkaline, the hay will be lodged and so thick a dog almost can’t jump over the windrow. It can all vary like that in just one pass. Lot of times I was a needing to drop more then a gear like say 3 to 1 or 5 to 2. TA doesn’t do that. Round baler is more forgiving on the size of the windrow but not a square baler which is what I was using. Could have bought a hydro. Quote

I've only across two my entire life. My cousins 1066 hydro and a 656 gas hydro at a place I bought a skid steer bale spear. And I don't think I want to take a chance on 50 year old hydro. I assume they are very costly to fix?? Thats why my cousins 1066 is parked. Plus the only reason I used either the 5020 or 1256 is at the time we only had one hay/loader tractor. Now we have three so neither get used for baling. And my 1256 is an IH with the "Wheatland" package with the serial number 7506. I'll take that over any hydro except maybe a IH (not a Farmall) 1026 hydro Quote

That's the problem with a 1586 H1 is too fast and L3 is too slow plus you gotta shift range to go from one to the other and those seem like the gears you use in the field. TA helps bridge the gap with H1 low side TA. Quote
B.B. Posted December 31, 2025 Posted December 31, 2025 Hey speaking about 86 series... How about those backwards doors, the left hand shifters, the rough ride with the seat being forward (to which you can't see the drawbar to line up) and that there's no leg room and it's impossible to put fuel in it from a can! Not to mention that series ruined IH... By the way I'll provide a loving home for any unwanted and unloved 86 series tractors. 4 Quote

They have stairs as wide as City Hall at the bottom, but you have to turn your shoulders sideways to get through the doorway. Can't see the drawbar on those either. I was disappointed in the 86 air cleaner access and the decals burning off is just silly. I still have some sales literature showing how the cab is moved 1-1/2 feet forward. Wasn't that supposed to improve the ride? 1 Quote
B.B. Posted December 31, 2025 Posted December 31, 2025 And I still want a 4960 just so I can have one green tractor to cuss at Thanks for the entertainment and the stuff I've learned during this thread. If anyone has an unwanted and unloved 4960 MFD they don't want and don't love I'll do my best to love it and provide it a good home with minimal verbal abuse. Quote

As far as I know the 5020/6030 use the same trans gears. The 5010 was. Different but you could put 5020 gears in a 5010 if you changed all matching gears. The speed difference of about .4 mph from 5020 to 6030 is from other areas , bigger tires? Or maybe they ran different rear planetaries. Quote

I haven't had all three tractors running right next to each other but according to the manuals, the 5010 and 20 are the same speeds using the 24.5-32 or 18.4-38 tire. The 6030 is different but I can't remember which tire they used but I'd guess it would be those tires or the 20.8-38. One difference is the 6030 engines were 2,100 rpms while the 5020s were 2,200.

acem Posted December 31, 2025 Posted December 31, 2025 The sychro range is a good transmission. However I have alot of difficulty trying to explain it to a driver who has not driven one before. They just look at me like I'm crazy and say what??? Once you get used to them they are good. Most all tractors here sit outside all the time. The Sychro shifter guide is faded out and unreadable. For bailing hay you need a Hydro. They can give problems but most often the problem is in the controls or a line. I have had to replace both the shifter cables on my Hydro 186 and an internal line.

I just found the whole shifting back to park before going to the next range kind of cumbersome with 1 lever. Probably because I'm not used to it. I find that moving the left lever to neutral and shifting to whatever gear you want comes more natural to me. Most of the time I'm doing loader work. So I use either 1st or 2nd a lot then pick high for moving around, low for digging or pushing and then reverse. In snow I'll use 3rd quite a bit. Or 1st with the snowblower. So most of the time I'm just using the left shifter anyway. I suppose the JD is similar. You probably don't shift to park and change ranges very often on any particular job. As they say, different strokes for different strokers. Quote
