I have a 8560 with 226 hours. When I start it up and it runs for around 5 minutes the warning beeper will sound beep beep beep. Any ideals what would cause it to go off?? Our is there a million reason.

If it is almost exactly 5 minutes, that is an indicator that it is low or no pressure at the scavenging pump. That is a pump in the transmission that supplies oil to the top shaft that otherwise is above oil level. It is important. The pumps can lose prime or more often the sensor just gives a bad reading. It would be worth having this checked before driving it much. If you worked this hard all day with no oil on the top shaft, you will ruin the transmission. There are a couple of threads on this, but it is tough to find them by searching I bet. It might be worth the try though, as if I recall correctly, there is quite a bit of info.
On newer models, I think they went away from the internal pump and used the power steering (PS) side of the engine driven hydraulic pump to return oil in a manner that lubes that upper shaft/bearings/gears. That is a better system in my mind, one less pump and you would know for sure if your PS pump quit.

Called the dealer and he said that it is probably the sensor going bad, that they been having issues with them. I will be taking it back to the dealer to have them look at it. It is a shame that with 226 hours this makes the third problem with the tractor. Relay starting to shake my faith with Mahindra.

You dealer is likely right, it is almost always the sensor. It begs the question....why not get a sensor that is good for 10,000 hours? It's the little details that can get frustrating, we understand. Like all brands, Mahindra tracks the failure rate of about every part on every machine. We do not see any stats at the dealer level, but it would seem prudent to spend a little more and use top notch relays, switches, etc. I will say the problem was eliminated on the newer models when they redesigned the system to lubricate the top shaft.
IIRC, the sensor is near the top of the transmission sort of under the floorboard. But it has been years now since we have seen one fail, so my memory is sketchy.

To add to Daves post, when replacing the sensor for the scavenging pump, use the sensor for the engine oil pressure instead as it is a better quality sensor and will do the same job. I didn't just make this up, the Mahindra service rep told me to do this.

Even so, it's the little things like this that add up to disappointment. I'm a huge Mahindra fan, but they ought to use a better quality sensor. Whether it is reasonable or not, a few small problems can shake a customers view of the quality of a tractor that is otherwise solid. Once you have a little problem, you become more critical of the next problem, etc. Mahindra would do well on their Indian built models to really focus on the little things. They have the big things right.
I agree with Dave...sorta. But not with the conclusion. I think all sensors and relays should be high quality, but it depends on the cost. Some of these sensors get pretty pricey. Given that I got a beast of a tractor for 37,500, and mine has been quite reliable with a few minor hitches over 7 years, I'm pretty happy. I priced caseIH, JD, kubota, etc before buying, and they could even get close to Mahindra's price. I remember the JD "equivalent" was thousands of pounds lighter, could lift 600 pounds less, and cost almost 20k more.
And I have friends that have these other tractors, and they have occasional problems with them as well. Tractors aren't mass produced like a honda civic, with every kink and wrinkle worked out. They are going to have more problems, regardless of the brand. Don't lose faith in Mahindra for a few little things. You probably would have had a few little things with that other brand you were considering. Just my opinion.

Update on problem. It was the sensor that went bad. $5.50 part that went bad smh. Dealer did not have the oil relay to use so went with the oem part. Mahindra needs to put better quality sensor in there tractor makes the third one I have replaced in 260 hours. But I still love my 8560, she is a beast!
