Hello. I've had a b80 for the last 15 years I found a guy in swanton Ohio who has many parts brand new and old stock in fact his wife cuts acreage with a b80 and no one is allowed to touch it it's the only place I could find parts readily. If you add a couple ounces of prestone ring sealer to your oil you're smoking issue will cease immediately use it with every oil change you will be amazed. Check your torque on your piston head also.
xle5363 and I looked it up about the 4 speed your right about that ! that's weird because in the 60s they called that same transmission a 3 speed , they must have had to change the name in the 70s, when they started producing the so called 8 speeds
That's definitely not a "94".... that's more like a 74. By the way.... That's a good thing! You don't want anything that says Wheel Horse on it after 88... that's when toro started making them. Toro (I only capitalized the t on toro because it was the first word of the sentence) ....bought Wheel Horse in 85 or 86... but didn't start actually making Wheel Horse until after 88 - 89. This tractor you have here.. was built during a time when QUALITY mattered in this country. This tractor deserves respect... Don't park it too close to that Craftsman.
