Our 806 has some steering, brakes, and T/A trouble. Here are the symptoms.
1. The most often occuring and most noticable thing is when you put it in gear and let out on the clutch, it has a hit and miss chance of whether it will move or not. Sometimes it starts to move right away, just as it should. Other times you let out on the clutch and nothing happens. When it does this, if you push back in on the clutch and wait, you can see, feel, and hear a "clunk" and you know the tractor is ready to go then. After the clunk, you let out the clutch and it functions as it should.
2. When working the tractor and coming to an end, if you begin to turn push the brake to aid in the turn, sometimes it will stop moving, resulting in a scenario similar to symptom 1.
3. When it gets cold, or when its warm and you park on slightly unlevel ground, when changing the hydraulic filter, or just sometimes out the blue it will have no steering, T/A, brakes or be able to move upon starting (sometimes it will move but loose ability to move within a few seconds, push in on the clutch, wait, and it will move for a few more seconds, and so on). PTO and hydraulic outlets function properly during this time.
4. T/A function is delayed sometimes. Sometimes you can drop the planter in the ground and go to push the T/A lever forward and it will hesitate then lung. The same applys for pulling back on the T/A. And sometimes it works normally.
So what do you think the problem may be? MCV pump? Any help would be appreciated.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
