BX24 diff lock disaster ... How many others have had this problem?

[GolfAddict]

Addict, Sounds like very reasonable use to me. On an older tractor that had independent brakes (a foot pedal for each wheel) I used to feather the high wheel to do the same thing but the Diff Lock method sounds better because the tire would never spin continuously and the method doesn't require as much attention to the up hill tire. The independent brakes make for tight turns at the end of the row too. :thumbsup:

I sure thought it would be reasonable use. I've never used diff lock on any tractor to get "unstuck" as some folks seem to think is the only use for it. I've always used it in a situation where one wheel is breaking traction, to prevent the wheel from breaking traction.

I sure agree with your other point - if the pin is intentionally fairly fragile to sheer and prevent other more major breakage, but then can itself cause some similar major damage, seems not completely thought through in the design stage...

Kubota's response has been "TS.". My dealer has asked the Kubota rep to talk to me a couple of times and he refuses to even talk to me.

I like the machine overall, but based on Kubota's refusal to even talk to me about the situation, I may go green when it comes time for a new tractor.

Sorry to hear that. It looks like you have a problem with the local dealers, not kubota. I Just don't have a problem with my diff lock, and just like any color of tractor, when something breaks its easy to blame the manufacturer. If I broke the diff lock more then once in short period of time, then yeah I would blame them.

Really, I think every color have thier own quirks, its just a matter of what break down and how hard it is to get it fixed that would influence your decision next time.

No, he problem is not with the dealer. The dealer has asked the Kubota rep to contact me on at least two occasions. He refuses to even discuss the issue with me.

The dealer is a local company who I've dealt with for years. They treat me very well.

I think the biggest problem here next to mistakes done by operators engaging the differential lock is selecting the wrong tractor. The BX is more or less an "estate" tractor.

If you are going to be in the mud and off in the brush you need at least a B series. I know people are not going to like hearing this but the BX just does not have the clearance or the drivetrain compared to the Bs for this type of work. The BX was made to fill the niche for improved areas that still needed lighter tracxtor work. When I see people putting duals on BXs to plow dirt with and having to put on these other guards to keep brush out. I see them as just taking the cheaper route and sometimes pushing the equipment way past its limits. Sometimes you need to stop and see if you should get equipment better suited for your needs and learn how to properly operate it instead of pointing fingers at the engineers. Kubota has been making tractors for a long time and has not climbed to the top by taking shortcuts in engineering. Some of these dealers need to take more time in accessing the correct tractors for their customers as many are getting put into the wrong one just to get the sales at a cheaper price point. I mean come on redesign a treanny case so when the pin breaks it does not jam??? how about not engaging when spinning.

David, did you just chime in now or did you read the thread? Odds are that you CANNOT engage the diff lock at all if you are NOT spinning at least to some degree. You get 2 chances on a spin of the axle to make this happen.

This thread has been around for a while now and I don't recall the exact circumstances, but I don't believe the OP said he was at full throttle, full speed when this happened.

Mowing the lawn is too much for this tractor??? I don't think so. If using the diff lock on a BX is overusing a BX, and too much for a BX to handle, why the heck did they put a diff lock option on a BX?

Tasking things out of context If the lawn is too rough then get a B

Dave,

Didn't engage while spinning.

As said before,Minot bitching that the pin broke ... But to cascade into a $3,000 repair due to insufficient clearance that virtually guaranties that the case will be trashed if the pin breaks IS a design flaw.

I'm not saying that diff lock pins should NEVER break. Nothing is unbreakable. My issue is with the design where, if it does break, it falls to the bottom of the case and gets pinched by the gear(s) and punches a hole in the case, resulting in a $3k repair bill!!!

Not having enough clearance to prevent that seems to me to be a design flaw. A broken pin should be able to sit in the bottom of the pan, rather than being pushed through the case, creating such extensive and expensive damage.

I would like to hear from everyone who has had this happen and investigate the possibility of getting some consideration from Kubota for the cost their design flaw has caused.

from my understanding the diff lock is not pins between the the diff carrier and ponions as this system is expensive to make as well as unrelable.

Can some one confirm that the diff lock is activated by moving the axle to lock the spider gear with the diff carrier. Can't seam to find exploded view.

I have seen damage to the leaver due to opperators jumping on the foot leaver. This is abuse and may cause a pin to be shared off. May be its other parts involved as well.
