My 1300d has a bad leak on the front end. This leak is coming from the area where the front wheels steer or turn the tractor. Not an axle seal but where the axle pivots left or right. I ordered a part and got a big seal that fits in between the two parts. My 1300d just has a large (about 4 or 5 inch) o-ring that seals the 90w oil into this area. I put an oring in there that was a little to small and it worked for the summer. I just plowed my driveway and 3 days later my garage floor has a big trail of oil. If someone knows the part number or has a drawing that would be greatly appreciated. Any further information would be helpful on this subject and thankyou for your knowlegde!
