wheel stopped spinning in 3rd

[857lover 291]

i just noticed that on this new 6 speed that when i get stuck usually the wheels would keep just spinning and digging a hole but it doesn’t do that the wheels just stop trying to turn and the belt stopped moving because my wheels stopped moving why is this ? 

[Handy Don 12,451]

Worn or wrong size belt or contaminated belt surface are likely. However, the horse will slip the belt before it'll stall the engine so if you are really locked up, that'll be the reason.

The belt is slipping on the engine pulley.

it’s a brand new belt it’s one of those blue ones i forget the brand and it’s a 70 inch belt  and it’s all strange when it’s in 3rd high you let out the clutch to move and it starts slow and kind of builds up speed

it’s just weird it only does it in 3rd high

You need a stronger spring for the pedal return. 3rd gear applies the most force on the belt and it's slipping on the engine pulley as noted

the closer to one to one your engine to axle gear ratio comes the higher the demand you are placing on the belt. Stronger spring or a shorter belt will probably do the trick.

Not weird at all, it takes more torque to get things turning with less gear reduction.

You can find this yourself.

Search in the Files/Document section of this site for the Illustrated Parts Manuals (IPM) for both your tractor and the donor tractor (probably a 1067). Look at the part numbers.

You could try using your toe and pulling the clutch pedal back.  That would simulate what @wallfish is saying…

All of the above. Bob

@857lover  would go over every linkage point with aerosol lubricant , make the rust run out , grease related fittings , that linkage should work seamlessly , this is only a basic idea, don't know what the related areas are like , pete

You're going off roading. You do not have stock sized pullies. A 70" belt may not be the  correct length. Are your pullies  the same width? The same profile? 

 

Also The used transmission may have worn hubs /axle keyways. The load you're putting on it may be enough to make them slip.

 

How about some pictures so we can see your pulley belt set up?

i will definitely grab some pictures after work but  i have noticed my right hub keeps sliding back and forth like my set screw isn’t doing anything but also the trans pulley is a 4 inch diameter which is the same size as the one on my 3speed only difference is the bore is smaller

That rt. hub is probably your entire issue. What pulley are you running on the engine?

i’m not sure it’s the one that’s been in the tractor since i’ve owned it

May be Mike, but he states the belt is not moving.

Can't be sure from the picture but the engine pulley looks wide like a "B" bely pulley, belt should be riding high in the pulley so it has the maximum side contact area.

[squonk 41,320]

Pulley on trans also doesn't look stock to me and the idler looks high like the belt is too long.

[Handy Don 12,451]

I'm more noticing that the blue fabric on the top and bottom is there but gone on the sides.

Also, as noted, belt is riding low in the groove.

DEAD BELT is my vote (new belt = better grip ✅, ride higher ✅, pull the idler down a bit more ✅)

And yeah, non-stock drive pulley on the trans but I don't think that's the issue because the belt stopped moving.

The only thing that will stop the belt is it slipping on the engine pulley
