On the L3400 never had to replace mine yet but do keep a spare one (site glass).

texasjohn · Feb 27, 2015

I carry max load in my front tires, per spec on tire itself, as I recall, it's 24psi. I ALSO carry about 1000 lbs, maybe a tad more, on my 3ph as counter weight plus fluid in both tires for another 1000 lbs total extra weight. With this load, I can lift 2800 lbs pin weight just over a foot vertical.

Never have rolled front tire off of rim. However, power steering struggles to turn front wheels when stopped. And, front of tractor dips about an inch as I pick up the load and sidewalls of front tires squish down.

If there is insufficient counter weight, then the front axle must carry the entire FEL load plus tractor weight at the point that the front axle turns into a fulcrum and rear tires loading approaches zero. That's just way too much weight for just two front tires.

Net, high front tire pressure PLUS appropriate counterweight is the only way to keep from tire problems under heavy FEL loads.

Same with my L3240, texasjohn. One thing I'll caution folks on when carrying lots of weight in the bucket: When the back end gets light the rear tires will be much more inclined to skid, and since there are no brakes on the front wheels the only thing holding you back on a hill will be engine braking, but only if you're in 4WD. Even then, if a spline strips on the propeller shaft coupler, you'll find yourself in free fall and gaining speed quickly until you remember to drop the bucket. :shocked

What he said. Properly setting up and safely operating the equipment so it holds up over the long term doesn't always get the right measure of attention in these forums.

So if I may ask, what causes the need to replace the sight glass?

Previous owner painted over it.

Late to the party, but I own 3 L series Kubotas and work them every day in my business. They have been bullet proof.

I bought my L4240 hst nearly three years ago and it has proved to be a horse. In addition to the heavy duty bucket, I added some lights as the headlights are useless when using the fel. I'm right at 400 hours, have done all maintenance, and have not had any issues.

You would think this site administrator would have some pride in his work and fix this annoying example of a lackadaisical attitude......

What do the last two digits in the model number stand for, and what are the ranges?
I have a L4330. Do I assume that there was a L4300, 4310, 4320, 4340, etc?
Does each series run for a specific number of years, or just when they make changes to the model?
Or am I totally off base in my thinking?

First two digits are horse power. 2nd two digits are series. Yours is a grand L 30 series. That was replaced by the 40 series... Which was recently replaced by the 60 series.

I'm not aware of a specified model change interval... Whenever deemed necessary most likely.

Even better from the site linked above is their listing of prior models. There's a bunch.

Grand L3540 here with 724 loader and many attachments, Started with a BX23TLB then to a B3200TLB and now my L3540 which is just a great tractor. Very strong loader, never been under powered. I run a LP3584 rear blade and a LA2675 three point snow blower and with all the snow we had this year, removal was effortless, the HST Auto rocks.

I am not positive what Kubota uses as criteria to change the model number. Normally it's a specific amount of changes required. Some manufacturers will also do a series change without changing the model #. You see that in construction equipment a lot. I've ran JD road graders for 25 years and have had two "Series II" machines of the same model number. My old ford 3910, in later years, was tagged as a 3910 Series II. I don't recall Kubota ever doing that though. In the last 15 years powertrain changes have been common. Those changes usually dictate a model number change.

The L 4600 was replaced by L4710 a 4 tier go figure

Not picking on anyone but it should be listed as "Final Tier 4" engine... the L4600, L3800 and L3200 were "Interim Tier 4". The start of Interim Tier IV was when the L2800, L3400 and the L4400 had the "Extra Power" sticker added to them in 2008 or so...
