Got results from spring test and installation. I received 3 springs from McMaster Carr, all of 302SS material. All spring rate test were done to same test conditions, 1 inch of extension, force measured with fish scale.
Stock spring, 30lbs/in., .104 wire, .815 dia, 4.21 long.
MMC 94135K34, 22lbs/in, .106 wire, .840 dia, 4.00 long.
MMC 94135K33, 17lbs/in, .092 wire, .730 dia, 4.00 long.
MMC 94135K32, 13.5lbs/in, .080 wire, .640 dia, 4.00 long.
The 1st pic is of all 4 springs sitting together in order listed above.
I decided to install the K32 spring. When insalled, spring was still expanded, and pedal was pulled to top limited position. Pusing the pedal down was MUCH easier, but still offered enough resistance so it cannot be done by accident. I have attached 2 pics of spring in normal position with pedal up, and 1 pic of spring fully extended with pedal fully depressed. If you decide to change springs, pull the spring pin from pedal lever to remove and replace spring, this will make job much easier. If you think K32 spring will be too weak, try the K33 spring. They are less than $10 each, so you can't go wrong. I am really happy with the new feel of the diff lock pedal. Philip.

The seed is planted :laughing:
The other thing I need to do is put a light in showing when the machine is in 4X4

That is what I want as well. I told Kubota rep at National Farm Machinery Show that needed to be added. He said it was a good idea. Wonder how far that went up the chain? Philip.

There listening. I've had some in depth conversations with reps from Kubota Canada on the mods I've made and mods I'm still planning to do. The problem with these changes is by the time they act on them our model tractors may not even exist
I'm into modding another machine right now but will be working on the 4X4 indicator early in the new year.

Unfortunetely, that was 2 years ago??
I also asked about greasing the front axle rearward bearing. They looked at me clueless. I had to go show them on a model they had at the show. This was a factory rep out of Columbus Ohio?
I wonder if they monitor this site? So much they could learn from real life use and work experience.

They know about the site because I've personally sat down with them (reps) and showed them the site. They view my YouTube channel because they mentioned various videos I have up.
I would say they do. Face it. Any smart manufacture should. Doing so will tell them what really matters to there customers. I learned last month that photos of my tractor went back to Japan with a high ranking Kubota executive

Great idea on the spring. Will be following this thread for a 30 day report...
If you want someone to test the 17 lb one, send it my way.
Also, it would be nice if Kubota took note of the paint on their tractors. The paint on the castings is bad bad bad. They need to slow things down so it can actually get some paint on it.

I will update in 30 days. I will keep the 17 pound spring just in case I want to change out myself. But please, get the 17 pound spring youself, give it a try, and we will await your report. The larger the test pool the better, more feedback from different users would be appreciated. The spring and shipping is less than $10 from McMaster Carr. I don't think I could send you the one I have for that price, and they have next day shipping to my house for free. Philip.
This is NOT a complaint about my dealer. My Kubota guy is busy delivering several tractors a week. His work time is always taking one in or moving one out. He is 50 miles from me, and everything was done by email, phone and him coming to me. The same is true for the environ that surrounds his business, so I understand his lack of keyboard time.
With that premise understood, I have found that very few if any dealers stay current with their products or this site.
The knowledge found on this site far surpasses any in-person experience I have ever had from any dealer.
If product improvement is indeed a corporate concern, this site should be mandatory for the RSM's (Regional Sales/Service Reps) to understand the satisfactions and concerns regarding their products. We may be a small genre of tractordom, but it does add up.
And Mr. Short needs to market his modifications

I know plenty of dealers who are on this site on a regular basis.
Some don't comment and others do!

Ha! You really think so? Thanks :thumbsup:
Art,
I think that I need to modify my statement to "I have yet to meet or speak with a dealer that even knows about this website".
I am sure that there are dealers who frequent this site...just none in my experience.

Yes sir, I do.

I have a question about the dif lock:
When you step on the lever you are in lock position when you remove your foot are you still in Lock?
I have been told a couple of diffrent things about the lock. One is that it will stay locked untill you step on the brake or on the clutch. The other is the lock stays engaged untill you remove your foot.
Once you step on the lever how long does it stay locked ? The theroy that it is only engaged while you are on the lever really does not make sence to me.If your foot is the only thing that keeps it locked how are you supposed to keep your heal on the lever and step on the throttle at the same time? with the same foot? (Although that would not stop me I'd just use the hand throttle.) My throttle and dif lever are both on the same side the right.
I believe once mine is stepped on it stays engaged untill you either, clutch or, brake. At least that is how mine seems to work.

I don't know about all tractors but on both of my Kubotas it will lag momentarily after remove your foot before it disengages. It is not an issue on mine as it is on the left side and the HST pedal is on the right.

Not sure on the L5740, although I will familiarize myself more next Thursday.:thumbsup: On my L3710, the dif lock is on the left. It seems to stay engaged until the "friction" comes off the rear axle, and then the lever springs back up and unlocks. If i need it to stay locked, I must keep my heel on the lever, which isn't an issue, since my hydro pedal is on the right, and I rarely use the dif lock.

I agree with the friction statement that is a way to put it i guess. Hydro pedal you guys just have to much fancy stuff :laughing:

I grew up on geared tractors, but once I got used to hydro I got spoiled and wouldn't go back. They both have their advantages and disadvantages, but for my uses I really appreciate the hydro.

Once you remove your foot the spring Philip changed to a lighter spring rate will pull the lever up and release the diff lock. I like the idea of putting an electronic actuator on the lever connected to a momentary switch. I think it could be added easily while leaving the lever able to work with your foot as designed.

Well, I put the the lightest spring that Philip gave to us, which happens to be the same he used. Let me tell you, that was maybe the best thing I have done. It works fantastic. So much easier to use and it still released easy. Philip thanks for doing all the work on this.
If anyone needs a spring, I have two more. They only come in packs of three. 4 bucks for the spring and 4 bucks to ship. If you want one, let me know. It cost 12 bucks for 3 springs.
