    Let me ask my question a different way. I understand how the priming plunger works. Is there something called a pickup pump incorporated as part of the primer?

    attaboy Already checked all that. Need to know about the priming plunger. What is in there and how does it work? Is there an impeller inside that is cranked when the engine is turning? Thanks.

    Been without internet for a couple years; but need some help now. My D21 was running fine the last time it was used. It set for 2 or 3 months. Then wouldn't start. We can push fuel through everything to the injector pump with the hand primer. Don't have pressure out of pump. Is there...

    I have a problem with the forward/reverse shifter cable on my D21. Took off and tried to lube it with assortment of oils. No luck. Decided to replace. Havn't researched cost. Anyone know where to find replacement? Heard of place in Tulsa (about an hour away) the builds cables. Would like...

    Can anyone tell me or provide photo of what should be included at the bottom ball or swivel connection of the blade on my D21? There is a lot of play here. I can not get the grease zerk to take grease either. Removed the zerk and it is ok. What is the zerk supposed to lub? Country Boy...

    Thanks guys. My son and I took apart the banjo bolt that holds the very small plastic screen filter. That little bugger had so much crud in it you could plant potatos. Cleaned it up, but still would not run but a short time after filling the lines and regular canister filter. Pulled doxer...

    I had read here where you had talked about the screen. I was looking for it when I lost the part. Are you saying the screen is below the hand operated priming pump? Not where I found the part I lost that was attached to a spring? I have got to get one of those manuals on CD.

    Yes. It must be what you are talking about. It is about the size of a pencil eraser only about twice as long with a larger base on the botton end. If this is left out, would it prevent it from running. I could get it to run for a few seconds, varying from a few sputters to 15 to 20 seconds...

    I was having fuel problems. Have gotten to the age that fingers are all thumbs sometimes. Lost small black rubber part that sets on spring. Working in the woods and fell between dozer and track. Looked several times, no luck. I think it is part of the fuel pump that is mounted on side of...

    K5Cruz I saw you are in OK. If you are closer to Tulsa than Dallas, I would recommend Crown Products in Tulsa. My brother in law works for Cat in Tulsa, he told me about them a couple of years ago. We have saved a chunk of money with these guys. Fixed a cylinder for a John Deere baler about...

    I seen to have a more pressing problem than the grousers on my D21. I am having a fuel problem. I don't know if it is rain getting in my tank some how, or some kind of contaminate in the tank breaking down my diesel. Twice I have had the engine to quit. Once a couple of weeks ago. The fuel...

    Need Traction I need to get more traction. I can tell my D21 has more push than I can get to the ground. I'll try to post a picture to show what I think my problem is. The flat plates on the track are approx 1 inch. My son and a friend on his suggested I weld some 1 inch key stock to the...

    I had posted earlier that I was having trouble adjusting my tracks. The zerks would not take grease. Today I used a trick I had figured out on other problem farm equip. I took out the zerks (which would take grease when out of the machine) and screwed the grease gun hose in about a turn and a...

    I have two questions. Probably read the answer in the past but can't remember. 1. I need to put in grease to tighten the tracks. Could not get the zerks to take it. Used an ice pick to make sure the ball was loose and spring was flexing. All seemed ok, but still wouldn't take grease. Any...

    Plasma Cutter?

    Sorry it took a while to get back. Yes saddle cuts is what I'm doing. Getting a clean fitting cut with torch is a challenge. Thought plasma would do better job. However, I do have to make several plunge starts. The demonstration I have seen at the Tulsa Farm Show was so damn fast. I think...

    Plasma Cutter?

    We are considering purchasing a plasma cutter to use on the farm. We have steel pipe for fence building and need to finish one corral and start another. I was hoping for advice/info on what you have used, good or bad. Thanks.

    Darin I think the owners manual said to adjust to 240mm of play in levers. Is that correct? The right one was very close to that when I adjusted, the left needed more adjustment. The left one will work loose with a little use. I really need to get shop/mantainance manual so I can see what...

    A while back I adjusted the extra play on my controls to what the owners manual recommends. I think it was 240mm. Now my left control acts like the clutch does not want to release. I havn't "worked" it but very little since the adjustment. It seems to start freeing up if I use it. Is this...
