Okay, your correct. I misunderstood. But the major issue here is that the front is lifting of the ground, due to the loads they are towing.

No, think your misunderstanding.The rear wheels work (rotate), but the front wheels don't have traction, causing them to spin.

That is correct. The pull extremely heavy loads, increasing the traction in the rear. But then when facing obstacles, the front lift and spin.

No, there is a differential. Between the front, and between the back. Just not a 'central' differential ie. no diff linking the front and the back.

Well that is exactly what is happening, pulling 8 tons plus ungerground. So front rises, then when encountering deep mud, or tall coal piles the front tires start to spin. If I may ask, why do you say it is counter productive? It is 4WD, with differentials separately on the front and back ie...

Hey Everyone, This is a continuation to the 'increasing front tyre of tractor' project. This is a new approach I'm looking at, as I came to the conclusion that increasing the size of the front tyre would effect the drive chain negatively, and was not cost effective and essentially wouldn't...

Well it's a project for my Vacation work. So it's of the level of a corporate company. The tractors themselves get stuck in the sections where it is often very muddy, and tall obstacles of loss ground (coal). They get stuck in the mud, and loss traction causing the front tyres to spin...

Hi Everyone, I'm involved in the mining industry, and been given a project based on the towing tractors used underground. These tractors often have to work in ridiculous conditions, and my project is to investigate how to prevent these tractors from getting stuck in the sections, specifically...

Hi PF :) I'm a Mechanical Engineering Student and looking forward to further my knowledge. :D
