Need help/advice with an L2350

[hodge]

My neighbor has an L2350. It is low hour (883), and it above average shape. He and his wife bought it recently, and are getting acquainted with the tractor.
When the tractor is shifted into 4WD, the driveline tightens up within moving a foot or two. You can feel it- it won't free roll. Lift the front wheels off of the ground with the loader, and it frees up. If you don't, it won't shift out of 4WD- it builds up driveline tension that fast.
The tires on it are new, and I suspected that they weren't the right size. The front's are 7-16's, and the rears are 11.2-24's. According to numerous sources, they should be 6-14's and 9.5-24's.
Can anyone confirm that, is the first question. Second, for those who are versed in the correct front to rear ratio, is it possible to change just the fronts or rears to a different size and restore the correct ratio? Otherwise, the neighbors would need some 14" front rims and 4 new tires.
Any input is appreciated!

curious, went to CDN website... yeesh FOUR different rear, 3 different fronts !!!!
best to see what your USA website shows, maybe talk to a dealer ??

'locking' up does sound like the tires are NOT 'matched' ( rolling circumference )

hm, do they all have the SAME tread pattern ? Same make/series of tire ??

I'm wondering if say both fronts were replaced ? original bill of sale 'should' have tires listed on it.

^^^^^

Those were optional size rims/tires and the same as I have on mine.

However....tread type and pattern can affect the overall rolling circumference. So I would check to see IF the tires have been changed at some point.

I have no issue whatsoever with drive-line 'bind up' on my L2350DT with the same tire sizes.

Like @Flintknapper said the tires are the right size, but they could be the wrong RC (rolling circumference).

You need a ratio close to 1.6363

They are R1 ags.
Math has never been my strong suit- how do I calculate the rolling circumference ratio?

 

[GreensvilleJay]

one possible way ?
place vertical chalk mark on front and rear tires where they meet the floor,mark floor too.
roll tractor forward one full turn of the front tire. mark the floor where it lines up
roll tractor a bit more to get rear tire mark to align with floor ,mark that.
measure the distance between 'start and stop' of both. those should the be 'rolling circumference'
the RC 'ratio' will be either the front distance / rear distance OR the other way round.
I suspect it's front/rear as 2WD came before FWD or 4WD or FWA ?

Thank you, Greensville. I plan to monkey with tire pressures to see if I can get the right ratio.

Take a pic of the front and rear tread and I might be able to give you a better answer based off of that.

I'll do that in the morning. The front tread blocks are real tall- more than half way to rice paddy status.

Grab the brand name of tire too if you would.

The tires are BKT's- rears are TR-117's, and the fronts are TR-144's. The tread blocks on the front are a 1/4" deeper than the rear ones. I haven't measured rolling circumference, yet.

curious...from BKT's website....
tr-144 mtd on 7-16 rim, RC is 2223
tr-117,mtd on 11.2-24 ,RC is 3205

3205/2223 is 1.44

hopefully someone can confirm/deny my numbers but my gut says 1.44 is tooooo far from 1.63.

I'll measure and calculate today- I think that you have found the culprit.
They use the tractor moderately. They have about 13 acres of mountainous pasture that they bush hog. I'd guess that they put 20 or 30 hours a year on the tractor, up to this point. They take any advice that I give them, but they also are interested in putting as little additional money into the tractor as possible. So, short or replacing the front tires, adjusting tire pressures to get a closer ratio may be the best option.

To chase a relational rabbit for a minute- is the ratio 1.6363 unique to the L2350, or is it universal? Does it fit all Kubota's, or all 4WD tractors?

Previous incorrect tire dimension.

1.6363 is fairly common, but not universal. Here's a link to the low-down

Tire Question

I have a Kubota L2500 with turf tires. Rear 13.6-16, front 24 x 850-14. I want to go to R4 tires. What brand and what size can I use? My dealer has been less than helpful. Thanks

It's a combination:
The rears are too small, tread depth is very shallow and the sidewall looks short.
The front are too tall.
You could just put a smaller front on it and get it to function much better.
