Nothing like a fire trail

Just some pictures I took when back filling some holes I dug with our Cat
312 BL... prospecting for gravel.

Well with in the dozer's hill side capabilities... if you get real steep, it does have a tendency to slide.

That shouldn't be much for an old Cat skinner like you OCR!
That 750C looks good too on that hill side, and maybe Owl creek in the bottom?:drinkup

I finish 2:1 slopes with a D8 on a regular basis. it can be tricky on rock but you get used to it. one trick is to keep a berm on the down side and that will keep you safe.

Great pictures OCR. That hill is steeper than it looks in the third picture. You were holding the camera crooked judging by the horizon in the background. We flyers always go by the horizon. The winch mounted on the ripper is a great example of getting the most out of the equipment. Excellent!

Good eye 25c... and you're right... :thumbsup

I need a turn and bank indicator on my camera... lol

I suppose having the screen on the grid mode might help too... ;)

How's this... better?

That's interesting that you would point that out 25c... :thumbsup :thumbsup

Here's another one you've probably heard... ;)

"Maintain thine airspeed, lest the ground come up and smite thee".
One more... and it's not the place to be... :cool2

"Runway behind you... altitude above you".

Many more 25c, but the last two are some of my favorites... and true...

That last picture looks better.Those are some good aircraft sayings.My favorite is "remember to fly the plane ". Sorry about the hi-jack Beel.OCR and myself cant help talking about aircraft from time to time.We will get back to the steep slope topic.

I don't want to get us into a one-upmanship competition, I spent all day with a D6H on a 40-degree sideslope, occasionally steepening to 45 degree (1 in 1) and to be honest, the first half-hour was underwear-changing territory. The low point was my dinner-bag falling out of the cab door, leaving a trail of sandwiches all the way to the bottom. This was on dry clay, I wouldn't have attempted it on topsoil or anything loose. As it was a couple of times the top track spun.

In a later life, I was trialling a dozer with a prototype engine for a well-known manufacturer and was instructed to see if I could make the engine lose oil pressure while pushing. This involved max side-slopes which again was 1 in 1 due to soil conditions, 1 in 1 uphill, (I could have moved more with a wheel barrow) and just over 50 degrees downhill, which resulted in a footprint on the roof-lining. My rule of thumb is your backside always thinks the machine is 10 degrees steeper than it really is.

That sure is the truth. The true measure is read with a level and rule, or with a slope meter.

I do know you can get the steepest going down a hill. I have been steep enough that if you pull up on the blade, it stays and the tracks lift up instead. When you get there, it is a little too steep then, and you better be carefull not to go over forward, or to stay there long enough to loose oil pressure.

Just wondering what you do with the gravel and what kind you find in those hillsides? It's good to see that you reclaim those hillsides when you'r done.

I would imagine that if you find quite a bit of good rock, you would push it down to the bottom with that nice 750C! Easy work for a tractor like that!


Gravel is always hard to come by in most places. The closer you find it to where you need it, the better! In our area in SD the County has to haul it with belly dumps for up to 60 miles one way! Sometimes keeping 10 to 15 trucks running, but only getting 3 or 4 trips each a day. But what else can you do when your roads are made of clay?

We have quite a bit of limestone in our area around the Black Hills, and I work with several contractors in Eastern Wyo that have to use Scoria....kind of soft though.

The way your going about it, I'm sure your going to hit the Mother Lode of gravel in one of those hillsides! :)


Do you screen it when you find it, or just load it?

I know it can be very valuable! Always fun to see how everybody does things...Looks like real nice country! :drinkup
Best Regards
Scott C.

Not a bit... although the other end of that hill, is an old county gravel pit... :confused:... :rolleyes:

I think there's some pictures in the Dozer forum; Slot Dozing, of the other end.

Probably just make a small road... and bench load with our excavator, Scott.

Just load, if it's any good.

Makes a pretty road though... :)


Take care,

Going past to Steep!

Here's the result of an Operator getting in trouble climbing a steep and slick hillside. While climbing up the slope, he started sliding sideways until the track went in a trench and flipped. Luckily the cab went in the trench full of snow saving the cab from breaking all the glass and injuring the operator. He was not hurt. Lots of fun helping get the machine out while it was 5 below zero in Jan.:eek:

I have done the same thing myself and I found it a strange sensation when the rear end lifted off the ground instead of the blade. I was pushed up the slope by a 9G because the D8 I was on could not make it up there in reverse. From what I have read and heard, I suppose that kind of thing would seldom be allowed nowadays?

as long as the safety man dont see you...lol, i know its a scary feeling and probably not the smartest thing, but i think most dozers will climb better forward than in reverse
