left brake pedal missing?

i have a 1940 9N that has no brake pedal next to the clutch. i do have a brake pedal on the right. I don't know whether i should have a left brake. It doesn't appear that there was a left pedal on the tractor. i was wondering if some early 9N's had separate brakes for the rear wheels.

They all had separate brakes for the rear wheels.
Right brake alone on the right for 9N/2N.
Clutch and left brake on the left side.
Most likely it didn't work and someone removed the pedal.
Easy enough to look and see if you have a brake
drum on the left rear wheel.

All 9N & 2N tractors that were the 3 speed tractors had 3 pedals. 1 brake pedal on right side for right wheel. 2 pedals on left with outer one being the brake for the left wheel and used for turning assist. The inner left pedal was the clutch pedal and pivioted on the brake pedal shaft and there is a linkage that makes it so when you push the pedal only partway down it releases the clutch only but push it all the way down it not only releases the clutch but allso applies the left brake for stopping, you are supposed to use your right foot on the right brake at same time adjusting the pressure with your foot to apply them equal to stop straight. You have to have even if the left pedal is removed the shaft that it fastenes on because without it the clutch pedal would not have anything to fasten to. Without going out to look at my tractors don't remember exactly how that brake pedal fastens to shaft but if I remember corectly it is a clamp on side of pedal that clamps the pedal to the shaft with 2 bolts. Somebody could have removed those 2 bolts and took it off because they did not understand how things were supposed to work and thought it was in their way getting on the tractor.

on the shaft between where the clutch pedal hooks in the rear
and the inner face of the hub, look for a keyway cut in the shaft.
That's where the left brake used to be.
I've taken them off before especially on winter machines
when I'm wearing big boots.
