9n 2n 8n Brake and Clutch Modifications

Me and my husband have been searching for an aftermarket kit or a way to design a better set up on both our 9n and 8n for the angle which is needed to press the brake and clutch... instead of being able to extend our leg out and press the brake and clutch at about a 45 degree angle, the operator has to press them nearly straight down.

We have tried search Red Rock Mfg as well as some other sites for over a year but no luck. So far it has been quite difficult figuring out a way to modify the clutch due to the mechanism where by the clutch's throw-out bearing shaft needs (facing the tractor sideways) rotated counter clockwise toward the front of the tractor to engage it and then can see how there are some other lever/cam mechanisms which are used to connect the clutch pedal to it.

The brake pedals are a bit easier to modify especially the brake pedal that controls the right side. The left side is a bit tricky though.

Would love some ideas, how-to's, and detailed pictures if anyone has modified the pedals to be pressed closer to a 45 degree angle instead of a 180 degree angle.
 

Needed to specify that it is our 8n that has the right side brake lever that is easier to modify and the brake lever for the left brakes which a bit more difficult to modify.
 
Probably the easiest and most affordable
option is to find a 2000 or 3000, I
remember as a kid the naa with the
pedals set up like your N was the
easiest tractor to operate as a kid
because you could stand on the pedals
when I didn't have the strength to push
forward on the 3400 pedals

Do you mean that it would be most affordable to go buy a whole other 2000 or 3000 model tractor, or to modify a N-series tractor with 2000 or 3000 model brake n clutch levers?

It's not hard and many years ago I had ideas of making these for sale but decided the liability issues were too great. Any resemblance to the pedal system on mid 80's vintage Kubota tractors is purely coincidental.....

Have you made any of them or just drew up plans so far?

Have you put any of these on a n-series tractor?

If you have made them and put them on a n-series tractor, do you have pictures?

If these would be what we're looking for, would you be interested in selling them....we'll sign a waver :D

I just did the conceptual work and drawings. I would love to make some for you just to say I did but I am up to my a$$ in work and don't have the time for any new fun projects.

The idea is simple - the under transmission tube bolts to the rear flange on the transmission and the cross shaft runs on sleeve bearings inside that tube. Pedals run forward from the cross shaft and curve up at a 45* angle for easier operation. Clevis/rod linkage from the cams on the pedals and cross shaft to the rear OEM brake shafts. Similar linkage forward to the OEM clutch shaft on the bell housing.

On the 2/3000s you do push forward on the
pedals and not down like on an N.
Might be something to consider.
If you wanted to do away with the clutch
pedal completely look into a Select O Speed
tractor. Those just have a little pedal on
the left side called the Inching Pedal. Can
be pushed with just a couple of fingers as
it's just a hydraulic valve inside.
I posted about this 3000 SOS a couple of
days ago. It has power steering and also
differential lock which are both great
features. I think it's a good tractor for
the price.

Yeah that's likely the most affordable
option, sell the n and step up to
something with pedals that way to begin
with, as well as live hydraulic which
saves a lot of clutch use going in and
out of gear. Depending on the model
maybe even live pto or atleast power
steering which was common on them.
 
No problem and thanks for taking your time TOH to upload the diagrams and give us a good idea how to do it.

We can't believe how people say to just go out and buy another tractor that already has this or that on it. We don't have 2,000-4,000 to throw around but we do have metal, torch, welder, and a dad who's a machinist. So for less than 20.00 of materials and a few days work, we can make our 8n have what's needed to drive it easier :)

Probably closer to $100 in material but still a lot less than a tractor upgrade. I'll be interested in seeing the result.

shouldn't be too hard to rig a bar, fulcrum, bracket to make a hand clutch lever to push down the clutch.

9N,2N left brake....they make a hand bar to apply it.
Having one in hand as a pattern, wouldn't be hard to make a reverse one for the right side.

I'm tall and my back speaks to me sometimes.
I've found mounting the seat higher and rearward changes angles and makes the pedals easier.....without having to hit your chin with your knee.

ps....good, working like they should brakes, take very little foot pressure to lock em up.

Thanks for the input but when it comes to changing the foot brake to a hand-operated brake, this isn't as practical as it seems...at least not for me... if the left hand is needed to brake and the right hand is then needed to steer, it makes it complicated having to use the hydraulic lever at the same time when it is needed.

Concerning the clutch, it seemed easy at first just to simply make a new bracket for the clutch pedal which changed the angle which it would be pressed but there is also a tie rod and radius arm that is right in the same area.

We know it can be done but will take some detailed measuring and possibly some trial and error to get it just right... I'm a recovering paraplegic and only regained movement down to my knees and so have no articulation in my feet which makes the pedal need to be at a really close position to how I'm seated and then extend my leg to press the clutch.


The last picture will show a crude drawing of basically how I think TOH was meaning to the clutch
