The whole point of "it's not a race" is to ensure (or help ensure) removing and re-installing tthe loader is done safely.
Some guys are more mechanically inclined then others and will pick it up pretty quickly. Others, not so quickly. I'd guess quite a few residential TBNers never operated a wrench...then they bought a tractor. Those gents and ladies are the folks I'm writing to...
First time I dropped the loader, I'd guess it took about 15-20 minutes. I'm mechanically inclined, but I'm one of those methodical guys who takes his time. You know....read a step, perform the step....read a step, perform the step...
Now, after dozens of removals and re-installations, I'm quicker. My only issue now is a bad hand (result of a stroke) that just isn't strong enough to work those QD fittings quickly. Dropping the loader (including on and off the tractor) takes 3-5 minutes (estimated...never timed it). For me, installing takes longer...mostly due to that bad hand. Sucks...but a bad hand is better then being dead, right?
