Man, I would love to have all you guys come over and goof off on the property. Trail making is fun like Eddie said and I saw Tiber's thread where he is dong it too.
John,
I hear why you are questioning by bulldozing in reverse. Thank you for asking. It is a technique I found that is (for me) quite a bit safer than pulling the boxblade when first cutting the trails and roads. Here is why.
On some areas, (not all), if I start driving up or down an incline, transversing it, the entire tractor is tilted sideways quite a bit. It is very unstable sideways like that and even the slightest rock or boulder can send it over on its side. If I use the FEL to dig out rocks and such in my path, I am doing it all on that tilted side plane. If I should accidentally push real hard on a rock or boulder, I could skid over it and if my tires hit it, adiós man...I'm tipping over for sure. In any case, the path I make is still on that side slope using the FEL. Using the boxblade and tilting it to cut into the higher side still requires that I drive the tractor on that slope which has not been cut by the boxblade yet. I find that dangerous and it exceeds my pucker level.
On the other hand, using the boxblade in reverse and tilting it, I can cut into the high side AS I am approaching a tilted side slope. I do this one cut at a time, cutting the high side and pushing that dirt/rocks behind me making a level path for my tires to be on. Now the tractor is not tilted sideways but level. I continue this method until I get the sloped traversing trail down or up to a level area. Then I turn around and drag the boxblade in the normal fashion. I make umpteen passes that way, pulling, until I have a fairly smooth road or trail and it is level now, not tilted anymore.
So keeping the tractor level while I am doing that heavy ground engaging work is a key for me, reducing the risk of tipping over tremendously. If you have not tried doing that, You should give it a shot. Often when I back cut like that, I can push a trail down and through a steep ledge and just keep going down the slope I just made where you couldn't drive forward over it. The rear tires (and fronts) are always on fresh cut soil and are very stable and level. It is a very effective way to do it, much like a dozer with a 6 way blade would do when cutting trails and roads on side inclines.
And yes, it's hard on the drag links but just watch it on the size cuts you take. (I missed on one attemp, obviously) Hope that clears it up.
