2n Quadrant adjustment

Hi Folks

I decided to look at this quadrant lever this morning as the machine seems to be working properly in all other regards (except brakes but I don't have time to take the wheels off yet).
this is the lever as I found it. The lever is at the top of it's travel with the lift all the way up and goes down from there it's actually over the hole to bolt up the quadrant rail.

after the the adjustments I managed to get it to operate fully in the quadrant. these 2 pics show all the way up and all the way down. I can't seem to get it to have that range further around the quadrant but I was happy to get it inside. I was thinking though that this should have a longer travel to go from up to down. the book says to put 300lb on the lift but the mower was already attached which is maybe 550 or so # is it because of the extra weight that makes the lift arm range lower? I could imagine that the extra weight would make it drop sooner and faster than normal. If that is is the case then I might run out of room at the bottom of the quadrant when I have a plow on there for example.

all up

Loosen the 4 bolts that hold the quadrant assy to the casting and slide the whole shebang fwd and back to adjust. It only take a tiny amount of movement to adjust things.

That's how I fixed mine, then I installed a Zane Thang and it's all good.
 

I did that a couple of times and still the whole of the adjustable range is what you see in the pictures above. I did manage to move the adjustable range to within the quadrant instead of completely out of the quadrant I was just wanting an idea of how much action the lever has to make the lift go up and down I think the heavy mower is making this a pretty short and very coarse adjustment.

aise to lower or lower to raise is a very narrow range of movement, since that tractor does not have position control. Lower should begin as lever is moved downward from top by about 2 3/4 inch and very little more should lower fully & by the time you reach about 1 inch from top, lift should be full up. What is all that other available travel lower in quadrant for? To give you control when a plow is compressing the draft control spring & moving the draft control plunger inward. Without Position control as with 8N, you have basically an on/off (lift/drop) control.....not much "in between".

That makes sense. Its just that all my adjustment seems to be at the bottom
believe that if you slide the 4 bolt quadrant adjustment forward, that the control arm position for lift will be closer to top of travel.
 


I will give it another try. Not realizing it could be slid forward I took the instructions to mean rotate
 

Hrm well I used a small pry bar and slid it all the way forward and there was no change in the position of the arm.

ll the way fwd to all the way back should make a difference, very strange & a little difficult to comprehend, since that movement is doing the same thing to top of control fork that moving lever which rotates shaft with eccentric & that too moves top of control fork????
 
You have to adjust the draft control spring first and then adjust
the quadrant. When you have an implement lifted you should
just barely be able to turn the spring by hand. When you have
the draft control spring adjusted properly then measure down 2
3/4" from the top of the quadrant. With the forward edge of the
control lever at this spot slowly move the quadrant forward.
When the implement starts to drop tighten the bolts on the
quadrant. Then check it again because sometimes it moves
when you tighten it down and you have to start over.
