  • I used to work for a dealer and I though the article was decent. Roosa Master pump in place of Bosch late 1960 early 1951. Front mounted PTO handle not 1959 but late 60's There was kit to convert them to the front handle same as their was akit for the fiberglass grills in 63. The original power steering was Charlynn, later power steering Saginaw. There are a ton of little changes. 26 inch tires outsold the 28 inch here 5 to l

  • Good Article! Another area to check for wear is the front axle pivot. My axle(AG-adjustable type)had an elongated hole in the axle from previous owners not greasing the zerk on the end of the pivot pin. This condition also caused the welded-on block in this area to break at the welds, causing even more elongation to the main axle piece. You can check for this condition if you disconnect the two side stay rods. If the axle rocks back, the pivot hole is worn. You can also spot this condition if you see a notch or flat being worn into the bottom "Y" area of the two side stay rods, where the rods bolt to the axle. Solution; I had a local machine shop remove the frozen-in pin and machine out the axle hole. On mine, a steel bushing was pressed into the axle after the block was rewelded to the main axle piece. The bushing is sized depending on how much the axle pivot hole is worn, mine took a bushing 1-5/8" od x 1-1/4 id (for a new pin available from AGCO). An important note when machining the axle hole for the bushing is that this hole is on a 3-1/2 degree angle to the top of the axle surface (lower at the back of the axle, higher at the front). GOOD LUCK! Tom -1959 550 Diesel

  • I will pick up my 550 in about 3 weeks. I am really excited about getting this tractor. I have only seen it on internet picture but I think it is a good tractor. Your article helped assure me that I have made a good choice. Thanks so much for your time and effort in providing this. If I get problems I may drop you a line. Regards, Allen

  • Good article. Our 1962 550 gas has the pto lever beside seat. Our 550 had an industrial loader on it with crankshaft pump.After breaking several front spindles we cured the problem by installing an AC D14 front using the spindle and part spindle is connected to. We just boted this piece to the centre piece on the 550 . We installed the one tie rod under the engine to join the two front wheels together and use one tie rod on the right side to steer the 2 front wheels. Great tractor - didi alot of pto work pulling an AC 66 and 90 All-Crop.Would like to get a 550 diesel.

  • I have two early model super 55's. Both had a cast front axle and both of them were cracked near the center area where it is shaped like an "I" beam. In the mid 1955 they must have realize they had an issue and changed over to a solid rectanglar structure. The cracks can normal be seen by evadance of a rust line. jray

  • Very good article! I own a 550 and can attest to the ruggednes of these fine u.s.built tractors.One note; the front mounted pto lever was introduced in the early 1960's but a retro kit was available for earlier models. I believe this is the case with the authers 550.

  • We have a '59 oliver 550 4 cylinder gas in our family. It runs great and is in original condition. About 12-14 years ago, the rear tires were replaced for free by adding used tires on rims that were compatible, aleviating us of the need to re-mount, however I made sure that the original wheels(rims) were kept in our barn. The original tires are outside, too. One of these days we will get more tires added to the original rims. There is a minor problem but a neighbor said that the fuel valve dripping could be stopped by adjusting a nut behind the fuel valve,(in-line), by snugging the nut approx. 1/8th inch (not over adjusting) because the seal is a 'packing seal'. This releived us the problem of finding parts for the fuel line. I am assuming that our 550 oliver is approx. 40 horse 4 cylinder gas. I would like to know exactly how namy horse it really is producing, specifically so I know what to ask for when inquiring about it, in the future. It had trouble starting and staying started the past season(we use it mostly to haul hay out to the horses), however, I adjusted the air/gas mix screw on top of the carburator all the way in and back out 1.5 turnes, and it starts and runs just fine, except seems like acts like it wants to stall, while in use. (doesn't come up to 1800-2200 RPM's.) .. mabye someone can enlighten me on this and on where to look for fuel filters besides inline. thats all I know for now. Also enlighten me on the horsepower of this 550. Keep on truckin'.

  • I also enjoy reading others comments about the Old Oliver 55's and 550's. I drove two different 55's many hours on our North Alabama dairy farm in the 50's and 60's while growing up. The 55 gas engines were tough and reliable the only weakness that we had was the front axels and oil leaks in the PTO. My dad bought the first one in 54 and the second one in 57. I now have a '67 diesel that I am restoring just for old times sake cost money but what fun I am having. I think dad is watching me from above.

  • Great article. Thanks for all the information. I m looking at 550 that has a lot of play in the steering, about 6 inches. Is this easy to fix and how expensive can it be. Many thanks, in advance, for any info. Sam

  • I would appreciate any information available about a 1959/1960 Oliver 550 gasoline tractor. Feel free to e-mail me anytime @ 757.oliver@gmail.com. I am also interested in steering cylinders for the tractor at the present time.

  • This article is a fantastic contributuon to us Oliver 550 tractor owners. Thank you very much for passing along your time, knowledge, and experience. I recently acquired an Oliver 550. According to TractorData.com, I think it is a 1958 year model. It does have the longer PTO lever with the depressable knob. Having read here, I assume it is a retro add-on. The rubber boot on the shift lever is deterrioated such that I believe it has allowed water to gain entry into the transmission. I would like to change this fluid, but I am not certain if this tractor has two compartments, one for the transmission and one for the hydraulic system. Desiring to change both, I'd appreciate any advice regarding this issue. Thank you, John in Central Texas

  • I have an Oliver 550, about 1950 in good working order that I purchased 2 years ago. I have had difficulty finding a replacement hydraulic fluid filter. It fits into a canister below the seat less than 2" diameter and 4 -5" long. I ordered one but it was about 8" long and did not fit. Where can I buy the right model filter?
