Mahindra 4530 problems

Kbaer · Feb 19, 2009

I think I have eliminated the fuel as a problem. I changed both filters. Tractor ran great until it warmed up to around 140 degrees then the same problem. Think the problem is with the timing advancement sensor.

Dumb question: Does't the 4530 have drain plugs at the bottom of each fuel filter? My 6000 does...ie all you would have to do is slowly drain all the "water" out of each filter rather than change the filters...PS that "cracked" line that was mentioned sounds weird to me....BobG in VA

Yes, the 4530 has 10mm bolts on the bottom of the fuel filter canisters that allow you to drain them.

Well it turns out I had several problems. Problem number one was bacteria in the fuel system. Solution was having the tank and fuel system flushed and then adding anti-bacterial (my dime since the dealer said Mahindra doesn't cover fuel issues and they won't admit that the tractor had the bacteria when it left the dealership even though I told him the next day that I saw some black sludge in the water separator). After doing this the tractor would run great for 20 minutes (I timed it) and then start missing and sputtering. If the tractor was turned off and restarted it would then run great again for 20 minutes and same thing. At this time the Mahindra rep finally agreed it was a timing issue. I did notice the colder the outside temp the worse the problem. At sub-zero temps the engine would miss extremely bad but as the outside temp warms up the missing and sputtering comes less apparent.

Why all of these timing issues? This is one of several I have read about on TBN with these Mahindras. Does it have something to do with the climate being different from where the machines were manufactered? I just don't understand the what causes a machine to be out of time?

I worry about bacteria cause I store my fuel in a 55 gal drum. I can't seem to find any type of anti-bacteria additive locally. I use a Mr. Funnel when I transfer from fuel drum to tractor, and I haven't noticed any bacteria yet.

I think the timing sensitivity is because of a warmup issue. Timing is advanced for several minutes after starting. Then, when it retards, the diesel is very subject to cold stacking unless the engine has warmed to the operating range. I find it difficult to keep mine warm enuf in cold weather to prevent this, and a minor bump up of timing helps. I would sure like to see them use a better thermostat. - My Kubota diesels dont have this problem.

I just purchased a Mahinda 4530 from Iowa. Though the tractor had a mixed blend, it acted as if the fuel was gelled when I started it here in North Dakota the next morning. It had been below zero that night. I added fuel treatment, let it idle for a long time and it then began to run alright. I parked it in a heated shop for the day and then drove it home. It had about a half tank of the mixed diesel so I added eight more gallons of number 1. The tractor ran fine for the first six miles but then began to spit and sputter at higher RPM's when I got home and began to move snow. Outside temp was approx 13 degrees. Any suggestions?

I have a tier 4 that did the same thing here in Alabama. The problem was confirmed by bleeding the fuel filter. If the bleeding is successful (and if it is, it will only be for a short time) the root cause is an in-tank screen at the fuel petcock. This requires draining the fuel tank and removing the fuel petcock. The screen is about 8 X 50mm and is screwed to the petcock body. I used carburator cleaner and a tooth brush to clean mine. Note: the first time I bled the system it ran good for about a week. After that it deteriorated rapidly until it only ran well for about 10 minutes. Considering the problem you already discovered with the fuel this is my educated guess.

I have a 2006 Mahindra 6000 tractor and when I pull a bushhog or baler it loses RPMs. I changed the filters and I blew out the fuel line. The RPM's increased from 1000 to 1700 but it still does not have the power it needs and it is blowing blue smoke. Any suggestions.

Your problem could be debris in the fuel tank, blocking the outlet. I have seen that problem more than once.

We have blown out the fuel tank again and still no power when pulling bushhog, rake or baler. I have decided this Mahindra may be the worst tractor I have ever owned. I just bought it a few weeks ago and it has very few hours on it & it looks like new. I have yet to finish a job with it that has not taken twice as long as it should. Since I have never owned a Mahindra before, is it common to have all these problems with one? The dealer I brought it from will not even talk about fixing it since I bought it as used.

What do you mean the rpm increased from 1000 to 1700. What load? What was the idle/no load rpm set at? Did advancing the throttle manually help to hold set speed?
