FX-26D 4x4 Question

[sierrav]

Looking for expert help on my newly acquired Yanmar FX-26D. (Please be patient since I am new to tractoring). It’s a 4x4 but I can’t seem to get the front wheels engaged. There is a small foot pedal on the right floorboard which indicates up for 2WD and down for 4WD. I was working with this all day trying to get into 4WD, with no luck. I tried all combinations, in gear, in neutral, moving, stopped. I can push the pedal down in all these cases but the front drive still does not engage. I am sure of this because I got stuck several times with the back tires spinning and the front tires doing nothing. Sometimes the pedal stays down and most of the time I have to actually hold it down (to keep it down). But, even when it is held down, the front drive is not engaging. It is a completely reconditioned machine and I was told that the 4WD worked OK prior to delivery. Am I missing something here, or doing something wrong? Am I activating the correct lever/pedal to engage 4WD? There is a small lever just to the left of this pedal also on the right side of the tractor that is not labeled. Is that part of the 4WD system. I do not have a manual so have no other reference for what all the levers are used for. Any help on this would be greatly appreciated. Thanks. /forums/images/graemlins/confused.gif

You are locking the rear diff. The front engage will be a lever. It will just move back and forward. It is usually on the left side of the machine. The PTO wiil have several positions.

Thanks for your feedback. Well, ignorant me, I just assumed that the pedal on the tractor's right side (on the floorboard)with a label next to it with an arrow and "2WD" pointing up and "4WD" pointing down was the correct one for engaging 4WD. I do not remember seeing a lever on the left side (I will check tonight). Do you know what the small lever that I mentioned in my initial post, also positioned on the right side next to the pedal we are discussing, is for (there is no label for the lever, could this possibly be the 4WD lever? Thanks again.

I agree with Kaysupply about the pedal being the locking differential, If it is operated by the heel of your foot. The 4WD should be a lever located in the same general area as the pedal. It should be a short throw (in-out) lever that engages while operating the clutch.

BTW: Welcome to TBN.

Thanks guys. I will check this out tonight. I really appreciate your feedback. So do I need to engage the clutch when I move the 4WD lever in either direction? That's assuming I indeed find the lever wherever it is located on my machine.

If the tractor is in gear use the clutch. If it is in neutral you probably wan't have to. I have slid it into 4x4 while moving not using the clutch, but I would work up to getting the feeling of how it works. For sure not while under a pull or stuck and spinning. Another point to bring up, never engage the diff lock without using the clutch. If you do while it is spinning you could be buying a new axle. They are hard to find, is an understatement.

Can see it in the pic. The short lever above the foot petal for diff lock.

Yes, I do see the 2WD/4WD lever you are referring to. Seems the same lever for my FX-26D is positioned near the floorboard just to the left of the Diff pedal, but similar to yours, both are on the right side of tractor's center hump. When I push this lever forward (down) it still does not engage the front tires. The lever moves fine, it just doesn't do anything. What should I hear or feel when I move this lever forward and backward? By the way, your tractor looks very nice and has more decals than mine. Some of my levers, pedals, and knobs are not labeled so I have no idea what they do. For example, the turn knob in the center below your seat, I have one also but it's not labeled. What does that knob do? Thanks for your help.

Sierrav,

Where did you buy your tractor? And did they offer any operators manual or instruction with your purchase? How about a warranty if there is something wrong with the 4wd operation? I am only asking as it would seem your (ANY) Yanmar would shift into 4WD without any problem...unless there is a linkage, or other problem yet discovered.

Hope you get it figured out and good luck.
