Anyone use their 8n to pull logs?

[8NChris]

Your 8N or any axle is 2 wheels drive. With an open diff only the spider gear moving both wheels the wheel with the least resistance will spin. When that happens power is taken away from wheel with the better traction.

When I was young two 80 year old oaks died. The 9N alone couldn't pull them and the 78 Chevrolet 4 door service bed truck didn't have the traction. As a team with the 39 in the lead both the trees were drug to the burn pile.

I worry about flippping. So, i got a longer chain ran it to the front bumper under tractor center then had a loop short chain at the lower 3pt chains and then to the log. The front bumper took all the pulling strain. This also allows for more forward traction from the open diff(dist load).

SMH...
If a tractor is not heavily ballasted in the rear it will always slip the rear tires before it rears.
If these tractors were used all these years the way you are suggesting there would be no front ends left under them.

I would est the angle of the chain under the tractor at maybe 8-10 deg drawdown. Lets say I'm pulling a log and the total force on the chain is - oh, something rediculous like a 1000Lbs of force. We'll give the length from the bumper to the log at 20 feet and the height of the bumper at 2 feet just to be simple. Given that trig solution, the downforce from the chain is exactly 113.64Lbs. The balance is rearward. Now, given that my 8N spends approx 7% of it tractoring life pulling logs and the added 113.65Lbs of downforce on the tractor front, with zero repair or lubrication I would guess that the front end will be destroyed in approx 326 years.

YMMV

Doesn't the front bumper for a 8N attach to the front axle?

I'd hook to the front (long chain/cable) and go backwards pulling them up the hill. If you're worried then run the chain under the tractor to the draw bar and still go backwards on the flat ground. I've drug lots of logs with my little Furgey TO-30 (live on pretty flat terrain) and wrapped the chain around the axle horn. Eventually you'll run into logs too large to pull no matter what. In that case the simplest and easiest solution is to BUY A BIGGER TRACTOR. No law against owning more than one you know.
