Not knowing the entire contents given in the owners manual immediately makes you an unsafe operator of any piece of equipment.
A good driver would never claim to be good based on a no accident status as they will admit right up that not having an accident is more a matter of luck than skill! There are just too many nut jobs out there that didn't read the owners manual causing accidents and not being involved is a matter of LUCK
On a serious note There is in many cases a good bit of information in the owners manual that will enhance your ability to operate the machine safely, more efficiently and in some cases even help to make it last longer. So It really should be considered a Must read document with any piece of equipment.
I have seen a few posts here about people who have lost traction with the rear tires when operating on a slope and claim that they use 4 wheel drive now to ensure that it never happens again. I get a chuckle out of this every time I see it because if they read their owners manual it gives the proper way to drive on the slope when you have a load in the bucket and if they follow it they would not have lost the traction in the first place and would have never put themselves at risk to begin with. Now, I know that turning around and driving down the hill in reverse might not sound like fun but in all honesty your front axel isn't designed to carry the weight of the tractor like that going down the hill, in all honesty its worse than having no
ballast on the rear and if anyone wonders why we have broken axels 5 and ten years into ownership they can look back at that practice and smile knowing they got lucky that the axel didn't break while going down the hill the wrong direction with the 4 wheel drive engaged causing a more dangerous situation.
Reading the owners manual is not only good from a safety standpoint but can also be good at prolonging the life of your expensive piece of equipment so it is wise to read it cover to cover and foolish not to!
