New to me MF150

My 1967, 150 has 3 speeds forward and one reverse X Hi/Low range = 6 forward 2 reverse. No Muti-power.

Maybe you have a Chevy 4-speed knob 🤭

I was looking through the owner's manual and the shift patter doesn't match what is shown on my tractor's gear shift knob vs what is shown in the manual.

But knob looks weathered and original just like the L-S-H knob it is next too. ...

Not sure what to make of it.

The shift patter on the knob on the tractor is like this:

R 4 2
1 3


The picture I see from the owner's manual is

R 3 2
1 4

But the owner's manual could just be a generic picture?

When you get the steering box tightened up, check the turnbuckle and pins for wear a small amount causes problems with the power steering, if they are good loosen item #54 in the picture you posted a little that will allow the steering arm coming from the steering box to move the turnbuckle a little more in turn moving the control valve more which is what controls the amount of steering assist,only thing is if loosened to much then you will have excessive steering wheel travel. Be patient trying to adjust this type system it is sensitive to adjust but will work once you get it tweaked. Your two stage clutch release bolts may need to be adjusted tighter even though it releases now, less clearance requires less pedal travel to work thereby allowing the pedal to operate at a lower level and still work both functions .
 
Is there a shift pattern on top of the transmission case? I know the older tractors had that. I suppose it is possible someone replaced the original knob with the wrong one.

I don't believe it is cast into my 150, but I will look when I get off today.
 
Found a picture of a 135 4 speed shift pattern on the knob.

If my 150 was a 4 speed, would the shift pattern not be the same because it's the same rear end as a 135?

This does not match what is currently on my tractor.

Actually, did some more looking in the parts book, seems like you can have either knob for a 4 speed if you have an 8 speed with integral rail vs a slave rail?

What is the difference in those two, and how can you tell them apart?

Yes, the 135 and 150 4 speed would have the same shift pattern. That knob probably doesn't go with the tractor.
 
Decided to add some steps to help get on the 150. Since it is a row crop and the floorboards were above my knee standing next to it.

I didn't have as much trouble as my wife did getting on the tractor and I intend on turning her loose on a bush hog on it this summer.

Looked lots of step options that were available online and decided to buy some aluminum hoop steeps that mount to the pinch seam of a pick up truck. They we ~$40 shipped to my door off of eBay.


Had a little more cost in angle iron and carriage bolts, but I mounted two steps for less than $80 and very little fab time.

Happy with the steps so far. I'll probably pull it all off and paint it soon, but is easy enough to unbolt and take off.

I see your 150 has IPTO. FYI that system has a small puck style brake pad to hold the PTO shaft while not engaged. It wasn't designed to stop centrifugal force from the brush cutter. I installed an overrunning clutch to the PTO shaft to save the brake on my 150.

It has a live PTO with dual stage clutch. Not a hydraulic independent PTO.

Best I can tell there is no brake on the PTO.
 
Question about the throttle adjustment.

I've got it working ok, but I've got some slop in the linkage I can't figure out completely yet.

A lot of the slop seems to be up and down with the throttle lever in the dash. The rod into and out of the dash. I don't see what I can adjust specifically to help eliminate that?

Just trying to get it to move smoother, now it will move but as you try to gently open up the throttle and it will catch suddenly and jump up. When it does that you can feel the throttle move up towards you from the dash.
