However, this new innovation also comes with one key disadvantage that makes some tractor users somewhat sceptical. Seems like I read a couple years ago that Kubota was considering def in some of the really big models. My guess is it will be some time before you start seeing those engines used in tractors. DEF is available at Kubota Dealers, Auto Parts Stores, Truck Stops, Truck Dealerships and Engine Distributors. But it does have a diesel particulate filter. Sum of the smaller kubotas like some models in the l series still don't have them. DEF expands when frozen as much as 6.5% - 7% by volume. Lets take a look at the science behind DEF when mixed with exhaust. S spacemanspiff Member Equipment M5-111 Some models utilize a different type of fluid altogether. Once these parts are removed, you will need to have your ECU flashed or tuned so that it does not look for these parts. From a strictly chemical disposition DEF is a mixture of 67.5% deionized water and 32.5% urea. 6) They came to America in the late 60s. The vast majority of these systems use diesel exhaust fluid (mixture of urea and deionized water) sprayed into the exhaust system to break down the generated NOx into harmless nitrogen and water molecules. Do These Tractors Use DEF? 9 Brands Checked! - UpHomely The 2011 5500 has been a troublesome truck and the DEF has been part of the problem. Use baling wire to mimic the hose routing then measure it.

One important maintenance task that Kubota owners need to be aware of is diesel exhaust fluid (DEF) yes, Kubota tractors need DEF! The answer is yes and no. The result is that NOx is too high. The high horsepower engines are equipped with the SCR and therefore can use DEF. $2,995.00 USD. New Holland tractors started using DEF in 2011 to meet governmental mission regulations. Treat the DEF tank just like you would the fuel tank; you dont want to end up stranded somewhere because you didnt refill the DEF tank. That said, none of the LS tractors engines require diesel exhaust fluid (DEF) to meet EPA standards.

Kubota SCR DEF Quick Guide | Coleman Equipment Usually the first digit of the date code represents the batch number and the next 6 digits reflect the date the batch was filled at the factory. The new models in the range 50-60 horsepower series are equipped with Mitsubishi common rail. DOC can be used in conjunction with DPF in higher horsepower. What was final year of production with no DEF? DEF is mostly sold at truck stops in big jugs containing multiple gallons of the stuff. Are the new engines higher installed cost, the reason Kubota didn't use them on their tractors? The 2013 model does not require DEF fluid, the 2016 does require it. Fuel mixed in with the SCR finds an added source of elements to burn. Did they screw up in the first place and now have to backpedal (like Navistar - now switching to DEF because they could not reliably meet emissions with their announced low cost simplified design). Many diesels use both a DFP and either EGR or SCR to control pollution as they are aimed at two completely different forms of emission and each pollutant tends to form under different combustion conditions. SEE DEALERSHIP. Kubota becomes first Japanese winner of DIESEL OF THE YEAR with its new V5009 engine. I wonder if this has something to do with the issues some people are having in extremely cold temperatures, with the new engines. However, most of these brands made by TYM are always treated independently. If the DEF is stored at ambient temperatures of 75 F with no major periods of exposure to heat over 86F then the batch of DEF will last roughly two years. 1. DEF weighs about 9 lbs per gallon.

The way they do that is to deny the engine some oxygen, which is why they re-circulate the exhaust, since it is some O2 with mostly CO2.

The new engine models have been certified by the US Environmental Protection Agency (EPA) and California Air Resources Board (ARB). Saturday 8:00-12:00 Every one of the manufacturers figured out a way to cut down on the NOx levels all the while making more horsepower and torque than ever before. CAREERS This is required because the DEF flow also cools the DEF injector in the SCR muffler. I have an L4701 but I know some guys at work that have to add DEF to their diesel trucks all the time. Always consult equipment operator's manual and follow safety instructions before operating or servicing any tractor or equipment, or attempting any task. A diluted DEF without the mixture of 32.5% urea can be damaging to DEF and SCR but cases of that happening are rare. The SCR systems are designed to provide heat to the DEF tank which will quickly thaw the tank and supporting supply lines. Kubota has issued a recall for the M5-111 model due to these issues, and they are working on resolving the problem. Ford, G M, and Dodge did start selling DEF trucks in 2011 but the complete changeover did not take place till the 2012 model year.
