Hi guys,

I'm in the market and this model has caught my eye. Its a 2014 with HST.

This is listed as an interim tier 4 model. I am wondering does it have a computer that will need a special scanner to work out what is wrong or will I be able to work on it myself?

What does it have in regards to the emissions gear?

I was also looking at the same vintage 3400 HST but prices I've seen around me are only $5K give or take difference so I'd opt for the bigger girl in this case. The l4600 will be bigger than I need but I like the idea of extra lifting capacity and getting the job done faster. I also want to get either a grapple or grapple teeth for the bucket to help with clean up around the property and firewood collection etc and from what I've read the full grapples are heavy.

The prices are close to what they were originally purchased for, which is nuts. I am not opposed to a newer model but I want to be able to do my own repairs, which it seems like is pretty difficult if it has a computer with codes etc.

Thanks.

TractorData.com lists 2014 as the last year for the L4600.
Interim Tier 4,and indirect injection makes me guess it has the traditional mechanical injection system.
Most likely would have some sort of EGR.

Just my guess.
Good Luck!

I agree. I have an Interim Tier IV with either that same engine or a near cousin. Yes it has traditional separate mechanical injection. For emissions control mine has an EGR system which is active, but all mechanical. It runs fine at an idle and has required nothing.
There is a basic engine computer for the dash and some transmission controls - but it is very simple.
The EGR-fitted Tier IVs were the last engines an old fashioned mechanic like me could work on yourself.
And depending on model and backlog they stopped selling Tier IVs in the 2012 to 2015 time frame.

BTW, just a technical point. A mechanical injection system can be either indirect or direct injection - and so can a computerized system. Direct vs indirect has to do with the shape of the combustion chamber, not how the injection is controlled.

Thanks for the reply.

I have looked at the parts breakdown on kubota and don't see any EGR items listed, nor any sensors other than oil and temp.

I had read online that interim tier 4 had some added sensors/egr etc but that must only be for certain manufactures, perhaps.

Thanks for the reply.

It doesn't list any type of ecu but I wondered if there was one in the dash assembly as that is a pricey item.

The L4600HST and our M59 both seem to use the same series -03 Interm Tier V engine, but the M59 uses the turbo version and has some simple mechanical emissions parts for Exhaust Gas Recirculation.

Neither tractor has the newer type emissions ECUs in the dash that you are worried about. The L4600HST and the M59 are some of the last simple ones.

As far as I can tell from engine specs and parts diagrams the L4600HST does not even have the minor EGR parts our M59 does. So you would be doubly good to go with no exhaust related parts on the L4600 at all. At least I cannot find any in several references checked.

Here is the engine info for the L4600HST. Looks very good.

Thanks for that.

I had seen the first page of that in my search and the "E" part of the E-TVS raised my concerns about an ECU.

Going to check her out tomorrow

I'm not sure what the "E" stands for in the Kubota engine ID scheme.

My best guess is that back in pre-2015 when Kubota initially used the "E" preface is that the "E" referred to Emissions rather than to Electronics. At that time most manufacturers still believed they could hit the emissions requirements by simply improving combustion geometry.

Our Kubota is an Interim Tier IV Kubota M59 (2008-2015) & has engine type V2403-M-T-E3B
It has individual cylinder mechanical injection, so there is no connection between its mechanically driven emissions reduction equipement and any electronics. I think that is what you want.

If so, the easiest way to be sure is to look under the hood. You want to see four individual injector tubes running from the injector pump to the injectors in the head. That means it is a traditional diesel with a 4 lobe injector cam controlling each individual injector mechanically. Bulletproof old style technology. It will have electrical wires running to the glow plugs, but not to the injectors themselves.

On the other hand, if it is a newer Common Rail, then the engine model ID will often include "CR", and when you look under the hood there will be a single tube from the injector pump to pressurize a common pressure chamber up at the head. It will have a computer. Has to have, because each injector draws fuel from the common source and each injector timing is controlled via a solenoid by the engine computer. This new CR technology is more efficient at fuel and emissions, but requires a computer to run. In spite of everyone's fears - ncluding mine - this Common Rail computerized injection system has been around now for over a decade in tractors and longer than that in cars....with no real problems.

I don't have a fear of the modern stuff apart from the requirements of a dealer being able to pull codes. If it wasn't for that I would buy a newer tractor. The 2014 I'm looking at is basically the same price it sold for and about the same price as a lightly used 2-3 yr old tractor.

I've got some muscle cars that I do most of the work on and also more modern cars as well. For pulling codes on the modern stuff I have a $25 bluetooth reader. From what I have read the readers for modern tractors are really expensive.
