Well, are you running radial ag tires on your tractor? yes-no-maybe?
Mine were run that way for many years also till the side walls gave out. It was explained to me running them "squishy" put too much stress on the sidewalls hence their early exit probably. But you run them how you like.

never heard such expression 
Living in city and for weekend go to fight with my jungles.What are you using to file the rakers? That is the one sharpening job I hate.Thank you for this comment, Helo. Gives me some bit of hope. Of course, if 2 million Unkrainians have fled, that still leaves 40 million of them at home under duress. The madness has to end ASAP.
To not derail this thread, I am excited to get back to some firewood production with spring's arrival. Unlike the diehards in here, I am a fair weather firewood producer. Not interested in frozen fingers, shoveling snow to clear my log piles, or dealing with logs frozen into the ground.
So I got all 6 of my blades sharpened up. Finally realized that I need to take the rakers down a bit also, they were just as tall as my teeth.
And I finally broke down and bought an affordable peavey (timberjack). Hope this thing holds up ok. Anyone like to use these things? I figure I will remove the leg after I clear my current log piles down to the ground, and just use it for rolling logs after that.
I'm not deezler but I just use a small flat file. After every couple sharpenings I give the rakers a couple (yes two) strokes with it, takes less than a minute per chain. I do not use one of those little gages as to me they seem a waste of time. I can tell by the bite of the chain if I took enough or too much off and 2 strokes is about perfect.
If you can use the pre-cut piece hinge method as Helogabals suggested, you can pull from the side if you have a strong anchor point. You don't need to pull straight back towards the felling tree. The hope would be that the top of the tree falls between the grove of trees before it becomes vertical, so by only cutting part of the way through, you give yourself a hinge to kick the tree outward so its moving towards horizontal not vertical. I guess you could alternate hinge cuts, so the tree goes back & forth as it lowers like an accordion. Then you wouldn't run out of real estate. Sometimes you just need to get the top low enough to clear the tops of the others.
One for firewood / plowing / utility etc
I have one like this, it works fine, but I feel the top hook has a bit too much play in the hinge, & it could be a tad sharper, each can be remedied, just haven't yet. I'm still on my original handle. I was also gifted a smaller one of similar design, but painted red with a integrated steel handle, its a little less bulky so I tend to use that more.
It does happen DEPENDING on what brand/style of tires you have or had, you still haven't told us what they were.
