I just explained this to the tractor operator that was giving me a ride back the other day when he said the D8 should have wider tracks like the D6s. Not gonna lie I used to think the same way about what you said for the snow, got me a little light chevy colorado with wide tires thinking it would be great in the winter... it's great for riding on top of thick snow but sucks on the highway after it snows.
@@DieselandIron I've operated Cat high drives and Komatsu low drives. I'm trying to figure out if there are types of material/jobs where one is more productive than the other. I cut down a 95,000 ton pile of asphalt grinds with the komatsu. Lots of maneuvering in the pile. Not sure if the Cat high drive could have done as thorough a job. Thoughts?
@@RiddickMaximus From what I understand the high drive doesn't really make any difference in production. I've been told it's really to get the finals up out of the material so they aren't getting hard packed with mud which reduces heat and wear. That being said, that's all third hand information so I don't know for a fact.
@@DieselandIron Getting the final drive up makes sense. Being that it raises the entire dozer higher in the air, I was curious if that makes a difference in stabilization, maneuverability in say narrow spaces?The Komatsu d37x did a great job for me.
Plow with a skid tracked skidsteer, I have winter tracks that work great, but they bog down once the ground thaws. I have gotten good at track swaps every season.
For those who still do not get Bryan’s point or have doubts, go and see what is the tire width difference in WRC vehicles depending on surface condition. As far as I can tell on a tarmac it’s 235mm, on gravel 205 whereas on ice it’s just 185. The lower friction(grip) surface gives the narrower the tyre gets.
Interesting, never actually thought much about that. I suppose that's also why you see LGP tracks more often for finish dozing sand or rock, right? Since the broader distribution of weight helps create less ruts in the material as you track back over your finish passes. I know when I'm doing capillary break with a skid steer the tracks definitely compact the rock somewhat.
LGP stands for low ground pressure. The wide pads spread your weight out to where your ground pressure is much lower. 7:20 wasn't a joke. I was trying not to pop my "P's" into the microphone so it sounded like I was saying LGB instead of LGP.
I remember being taught that back in the day. Thanks for explaining the difference.
Thanks for watching Ronnie!

The concept is very counterintuitive. Thanks for the comment!
Great explanation! I constantly have guys asking what LGP stands for.
Thanks for watching!
Thanks so much brother 🎉🎉🎉
Anytime my man!
These illustrated teaching segments with the scale models are excellent. More on dozers please.
What would you like to know about dozers?

Oof...track changes are for the birds....

You are 100% correct. Flotation is everything in those conditions
I needed more floatation today. Kept sinking in the mud.
Grab some 2x4's and some bungie straps. We can rig something up.
I'm not an operator and never driven any dozers. What does LGP mean and what is that joke about at 7:20? Tried to google it but didn't get anyway

@@DieselandIron I see thanks
Huh !!! How about that... :)
