I dropped my L4701 tractor (with LA765 Front-End Loader and BH92 Backhoe) off at the dealer for the third time on Sun, Nov. 8th. I picked it up on Sat, Nov 14th.

The dealer finally hooked up pressure gauges and noted that the hydraulic pressure/psi was (-50) under the normal range of 2320 – 2780 (was sitting at 2,270 psi). They have since adjusted it to (+40) over the normal range (now sitting at 2,820 psi). They also told me that they installed a set of shims (I believe in/on the pressure relief valve).

I had 2 different people, other than me, use the tractor Sunday after it warmed up for 10 minutes and, although better at picking up tilled dirt with the F/E Loader than before, it is still hydraulically weak and often dies, even when picking up in low gear/mode (hydrostatic) with high rpm's.

As I’ve stated all along, I don’t want to get the dealer in trouble, they’re great people. To me, this is a Kubota issue. I’ve e-mailed Kubota in California at least (4) times and received 1 response (“We’ll have someone get back with you soon.”).

I have received 2 calls from a Regional Rep, as recent as this week, but that person now wants to come out and see the tractor perform, along with the dealer (which is something I asked for a long, long, time ago). In my mind, Kubota has been very slow to respond.

To add injury to insult, I emptied my trailer Friday night, Nov 13th (no kidding), so I could pick up my tractor on Saturday morning. One of my heavy duty, spring loaded, chain binders broke loose during the process and hit me in the face – shattered my nose, blackened both eyes, gave me a severe concussion, broke my glasses, earned me a trip to the emergency room for 4 hours, almost put out my right eye, and now I get to have surgery to put everything back together once the swelling goes down…….having not met my deductible, of course, which means $6-$8k out-of-pocket. Not really relevant, but probably wouldn’t have happened if the tractor were fixed or didn’t have the problem in the first place.

If I paid $10,000 for a used piece of equipment that would be one thing, but I paid almost 5 times that amount for a brand new Kubota tractor………the tractor itself still seems fine – plenty of power, everything points back to a hydraulic problem.

I’d be shocked if Kubota ran a side-by-side test and had the same result with another L4701 with Front-end Loader.

Obviously disappointed and dissatisfied.

You have a very good tractor, but it has a problem and your luck isn't so good
at the moment. Hopefully Kubota will get this straightened out soon.

Sent yet another e-mail to Kubota customer service in California last Friday/20th. It's the day before Thanksgiving and no word yet. Extremely disheartening.

I called Kubota's North Region in Ohio just now in an attempt to speak with a human's voice. Tried (4) people in sales, (4) people in parts, and even (1) person in HR/Human Resources, nothing but recordings. I am not making this up.

Man, sorry about the incident. That really sucks. If I were closer you could use mine for comparison. My loader is a beast and doesn't exhibit any of the symptoms as yours. Hopefully Kubota will get you going soon. Pressure checks are helpful but flow is very important too. The dealer should have a flow gauge they can put inline and check for a possible restriction. Your can have good pressure but low flow and things won't work. You just might have a restriction some where.

Wow, That is discerning !!! I just bought a New Kubota and was hoping any problems would be solved without Hassle... I have a 35hp tractor with an 805 loader (72" Bucket), it can lift a loaded bucket that will lift the rear (liquid filled) tires off the ground.. The wife came running out yesterday to inform me.. LOL !! I was scooping wet #10 sand, an 11 ton pile measured about 5'x5'x5'. it's like the fine gravel they make asphalt with.. it wont lift a heaping scoop, but will a full bucket....

After 2 more weeks of not receiving a call back from the dealer rep here in Indiana, I called Kubota in Torrance, CA, this morning (Customer Service, found the number in my "Owner's Warranty Information Guide"). After I spoke with the same person who I had e-mailed at least 10 times in Torrance these past 6 weeks or so, he forwarded my call to Jim Carroll @ Kubota in Groveport, OH.

I believe the Indiana dealer rep (who hasn't called me back) reports to Jim Carroll, not sure. Waiting for his call back. Important to note, too, that the last time she and I spoke, I asked her for her bosses name and number in Groveport as it was obvious she was not willing to help me......she responded by saying "I'm driving right now, but you can get the information off of the back of one of your brochures." I bet that number is pre-programmed in her cell.

In the meantime, I went out and tried to pick-up a half bucket of sifted top soil. Out of 10 attempts, the tractor died completely seven times. Am guessing there is still a flow or volume problem with the hydraulics that's causing it to strain or bog the L4701 down until it stops/dies. On a scale of 1-10, I didn't push the tractor past a five, so it wasn't user error.

I am absolutely dumbfounded that it's so hard to speak with a live person at Kubota. Not like the old days where you could hit zero and speak with an attendant who could forward you to the right person.

And I like the fact that you go directly to voicemail when you do call Groveport. I've called there no-less-than 11 times now and have never once had the opportunity to speak with a live voice.

That's pretty poor of Kubota corporate. One would think they would have better representatives but guess not. There are two ways I remember from my time as an auto manufacturer rep to get a quick response. The first is to file a complaint with the Better Business Bureau. Second is to do the same with your state's attorney general.

Just curious, what was the engine RPM before the loader stalled it? Have you ever disconnected the hydraulics from the BH and tried the loader?

I keep it at 2600-2700 rpm's (yellow or 540 PTO). Essentially with the throttle full. Wondering if they didn't adjust the hydraulic pressure so high now that it's causing the stall (but still has a volume or flow issue causing poor performance on FE Loader). The tractor did not stall prior to adjusting the hydraulic pressure. Dealer never even put a set of pressure gauges on it until the third trip back to them, and I suspect they never checked the volume or flow.

I have not disconnected the BH92 Backhoe or hoses to date. Was hoping to get the tractor fixed before snow (next week) so I could drop the BH altogether and place it in my barn. Tractor is in same field that it's been sitting in since end-of-September.

If it has a sticking (partially open or partially closed) valve am assuming unhooking the BH won't have an impact? Not sure??

Well since Kubota isn't giving you any satisfaction you should start with the "nickel" fix. That is at the first rung of the money ladder. Did they do the 50hr service, or did you?

The only thing I have done myself thus far was to purchase and replace the primary hydraulic filter, which was right around 50 hours. I did that after the second trip back to the dealer and still had problems. The new filter didn't make any difference.

Re: L4701 with LA765 Loader (Fixed after 18 months and a 5th trip to a diff. dealer)

Update: After 18 months and having taken my new L4701 tractor with LA765 Loader and BH92 Backhoe (purchased 07/03/15) back to the dealer I purchased it from on 4 separate occasions, I decided last month/Nov 2016 to take it to a different Kubota dealership (after I stopped this summer at the purchasing dealer <Humphrey's> in Greencastle, IN, and the owner acted like I was crazy because I still felt my tractor didn't work right from a hydraulics standpoint).

Without even looking at the tractor, the owner of the different dealership (Edwards Equipment) in Danville, IN, said "you've got a bad or sticking valve, likely on your backhoe, we can fix it, no problem."

I left my L4701 with Edwards Equipment for a couple of weeks and they called me back to tell me that the valve on my backhoe (P/N# KUB7K523-85100) was, in fact, bad. Because the implements were now out of warranty, even though Kubota had a record from the start of the problem, I gladly paid Edwards $1,226.09 to order and replace the bad valve on the backhoe.

I'm extremely grateful that after 18 months someone (Edwards Equipment) finally took the time to figure out my problem. I've been paying a $498 dollar monthly payment for a piece of equipment that has been sitting useless in a field for a year-and-a-half.

To this day I am absolutely amazed that someone from Kubota's Corp here in the United States/CA, or their Regional office in Groveport, OH, didn't take my numerous e-mails and phone calls serious enough to try to help me. Rather, I was always redirected back to the purchasing dealership which couldn't fix the problem in the first place. And the one time I did finally did get through to the Regional Service Dept in Groveport, OH, last December/2015, the gentleman whom I spoke with was a complete, sarcastic, asshole. So much so, that I hung up on him.

I have to admit, it was tough/humbling taking my tractor to a different dealership because I didn't purchase it from them in the first place, but Edwards Equipment was more than willing to assist me, and for that, I'm grateful. So much so that Edwards will get all of my business in the future.

Sincerely, Kelly
Danville, IN
