yeoman 627

I found a yeoman 627. Garage kept. Everything is in great condition except the engine. Lady said she thought that someone ran it without oil. I havent had time to look at the motor yet. Has anyone used a different engine on these little tractors? ddh

Dwayne, I think that is a vertical shaft engine. If so, I have changed many on Murrays, Dynamarks, Sears etc. They are very universal. I just recently replaced a single cylinder Tecumseh with a V-Twin B/S Vanguard for a friend. Fuel line, wiring, crank pulley and throttle all had to be modified.

It runs. Other than no brakes and few other odds and ends it runs fine. Damn thing goes as fast in reverse as it does forward which doesnt seem right. I backed into the wood splitter doing about 90. Do all of these little yeoman's do this? ddh

I believe all the Broadmoors and Yeomans and maybe the Serfs that have the three forward gears have the same speed in reverse as high gear. I don't know about the transmissions with two forward gears though. Makes you have to ride the clutch in reverse...I don't like going that fast backwards.

I'm with you guys about going fast backwars. I don't like going fast. My Yeoman does about 150 backwards, but in the highest gear, it goes slow. I backed into our tomato plants when mowing the backyard!

Check to see if the belt is on the proper pulley. Underneath on the crankshaft there are two, the smaller upper one runs the tractor, the lower larger one for the deck, blower, etc. Found the same thing on my homesteader when I acquired it...the thing goes like the devil with the belt on the large pulley. Also, if the belt is on the lower pulley, the belt fingers can't do their thing and the clutch won't consistantly stop the belt for shifting (another symptom). Probably needs a shorter belt if this is the case.

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
