pulling track with out pin removal????

When you beat on the pin are you backing up the link with a heavy sledge hammer head? If you're just whacking the pin it will only bounce. It helps putting a bunch more weight behind the link to soak up the inertia.👍

Did you loosen the track adjuster, that is a feat in itself

Did you remove both master pin retainers

Has the pin moved at all? Keep in mind this is a small sledge hammer job, not a ball peen job

If there is much wear on the master pin it will help to draw in the links adjacent to the master link to relieve pressure on the pin

I was able to remove the track from both my D2 and R2 (4J - same as D2) tractors without splitting the track, just be backing the track adjuster right off and manhandling the track over both idler and sprocket. I had the tractor jacked up at the time.

Seems they ought to come off unless they are new and don't have much fles in them. It's been my experience that you have to get onto a side hill waist deep in poison oak. They'll come off all by themselves.

right, or knee-deep in mud will assure they'll come off.:Cry:

I once changed over a pair of D4 tracks, as I was told to do, without splitting them, and true to form, one came off very easily while digging into a ditch to winch out the 4 x 4 timber tractor which was aleady stuck after backing down into a ditch for anchorage to winch out its loaded trailer.
