2 Wheel Drive?

[tplace 5]

This might be a dumb question but earlier this summer I acquired a 312-8, I thought both rear wheel were drive wheels but now I'm unsure.  When going up a grade recently, on damp grass, I saw only the right rear wheel was spinning and attempting to get traction.  I've watched a few of the videos on transmission repair and it looked like power is applied to both axles.  Are the 312-8's single wheel drive?

 

Thanks!

The tractor is making use of the planetary gears in the differential.  It’s design is to allow tires to spin at different speeds for cornering, but often it leads to the tire with no traction spinning and the tire with traction remaining planted.

First things first. There's no such thing as a dumb question except for the one that you did not ask.

 

 

There were some wheel horses built in the late 60s and early 70s that had a limited slip. Otherwise, all of them are one wheel drive, so to speak.

 

Traction can be increased by changing tire type, traction can be increase by changing tire type, adding chains,  or adding fluid or steel weights

The differential on the 312 is much like the one used in your car or truck. If one drive wheel is on pavement and the other is on ice the one on the ice will turn faster because of having less traction. Weight would be the best way to gain traction. Filling your rear tires with liquid will probably do the trick, it will also add stability.

Thanks guys, that clears it up.  I guess I'll start looking at options to increase wheel traction.  I think I might start with adding chains first and see how that goes.

Ag tires. I haven't found anything yet that they won't get me through. Haven't been in the ice and snow yet though.

 

In a quick pinch like that sometimes shifting your weight in the seat so it is more over the slipping wheel will get you through.

Trust me Ag tires on hard packed snow /ice are absolutely worthless especially if you have to back up (ags are directional).  L107 runs Ags in summer and muddy season turfs and chains once the ground freezes.

I need to get some chains for this winter. It was happening anyway, but this makes me think it should be sooner than later.

Go with 2 link spaced chains and not the cheaper 4 link spaced chains. The space between the links on the 4 makes for a bumpy ride and the tire slips between the links grabbing.

Wheel weights will help a lot as well as fluid in the tires. More aggressive tires too. Wet grass is always slick and don't forget that your brakes grab the input shaft so brakes don't always work well going down hill. Which can make for a cheek clenching experience with a load on a trailer!!
