Kubota RTV-X1140 disappointing performance

[wilsonj]

Hi all,

I've had an RTV900 for about 11 years, and have been pretty happy with it. We now have 3 children and I wanted something that we could all drive around on, as well as still be a good work horse.
So I thought the X1140 would be a good fit. Very happy with the space and ride, but the power is greatly lacking in my opinion.
I think in the brochure it mentions 25mph (40kph) as a top speed, however I struggle with one person (me) on flat hard ground to get more than 19-20mph (30kph).
In soft sand with kids onboard it really labours and wont' go above 10mph.

I'd love to hear from any other owners about their experience. It just doesn't seem right that the X1140 is so much slower. When I hop on the old 900 its like a rocket in comparison.

Cheers

WOW my 2006 RTV 900 was much slower than my 2021 RTV 1100c.

Some of the newer ones limit top speed without seat belts engaged and soft doors latched….at least my neighbors does. My 2012 kawasaki mule does not have doors, and seat belts are still zipped tied. But its a slow machine anyways.

That is false, transportation is the owner's responsability as is stated in every Kubota sales contract. Many, if not most dealers even put a decal on the dash reminding the customer of this obligation.
Transportation is covered for most PSBs for a predetermined time.

I have the same model; it is no speed demon for sure, but it will climb hills like a mountain goat. Love mine.

Get the manuals and check your linkages, or bring it to dealer. Something must not be set up right. It should go the same as my 1100C and it does 25/26 MPH both on the speedo and my Garmin GPS.
There's a few really god threads on net tractor talk also that detail how to set them all up.

Thank you for the quick replies!

I should add in sand it feels like it is "slipping" and really bogs down. Won't climb that well, but it is adequate. It's just surprising and dissapointing.

Do you have any links to the set up pages ?

I have spoken with the dealer a couple times, however they have said wait for it to run in a little. But I can't see it improving by the margin needed to perform like Kubota say.

hehe, thanks. Yeah brake is off, and in 2wd also.

Thanks for the reply. So how fast does yours go ? Mine doesn't seem to climb that well either, but it is adequate.

The hand throttle kit helped my 1120. I would have the dealer check all the throttle/transmission linkages. Also it’s new and not broken in at all.

No disrespect to this forum, but I mentioned the other one just because there seems to be the most RTV info on it.

I don't have the links, but if you just go into their RTV forum there is all kinds of good info. There's a couple members on there that know how to get max performance out of them.

I seem to be pretty lucky with mine, or my dealer setup. Like I said, I can get up to 26 on flat roads and I can climb my hills with two bucket loads of dirt from my B2620 in the box at 9/10 MPH.
Hard to really tell the grade in pic but it is pretty steep.

Something must be wrong. If I recall correctly, that's the same engine in my RTVX-1120 and I can get up to the rated 29 mph for that model. I think the 1140 is rated for 25mph and I'd expect it to hit that.

There is an adjustment for the throttle cable, so be sure to check that.

Sorry, I missed that that was another forum, with a similar name! Went and had a read, however I'm not sure I understand the relationships between the engine throttle and HST. Assume you want both of these wide open at full throttle. But I'll have to examine the linkages to see if they are in fact moving all the way.
I did adjust the pedal stop under the accelerator, which allowed quite a bit more throttle.

I assume the throttle and HST need to be fully open at full throttle?
