Nightmare Mahindra

You have a Kubota. Odds are it is the same type of setup employed on our three Kubotas. On ours the knob only affects lowering speed ... and when shut off tight the implement will not descend from whatever position. -- but if its not at top position it will still raise.

Your right Larry the Kubota does go up will not go down if the speed control valve is closed.:ashamed:

Thanks for confirming.:thumbsup: The other is possible I guess. I just havnt seen it yet. :confused3:

The dealer called today and said my tractor is ready. The rep stated that in the manufacturing process a burr (piece of metal) wasn't removed appropriately and essentially clogged the main hydro line. I'm not sure this makes any sense. He said that this is why the three point wouldn't go down and the engine had the funky idle. He stated that engine was essentially bogged down trying to force the piece through the hydro system. Has anybody ever heard of such a thing or are they just blowing smoke. My biggest concern is what kinda of damage could this have caused. I'm just concerned because my tractor only has 20 hours on it. Also, is it typical in the manufacturing process to leave pieces of metal that could cause such a problem. This makes me question the quality of Mahindra tractors in general. I'll get my tractor back tomorrow and check everything out and hopefully the tech kept the piece of metal to show me. If they did, I'll take a photo and see what everybody thinks.

Seems that would take a pretty big burr. Get a good description of where it was lodged. I wonder if the relief valve was inhibited from functioning by the burr. I assume the problem occurred late in the 20hrs so there was only a short period of obstruction ... but it pressure was somehow prevented from relief it takes no time to hurt something in the pump. Pumping against relief pressure will load the engine, so the explanation is plausible on the surface. Dig deep enuf to assure that pressure was safely limited.

I didn't run the tractor at all after it started. What kind of damage could be done to the pump? and how would I know? is it even plausabile to know what damage could have been done?

Yes, stuff gets left all the time. My old Ford Service Manager told me some stories after I bought in a large chunk found on transmission fluid change attached to the magnetic plug. He told me to not worry about it.

First time I changed the hydraulic fluid on my 6520, I found several small pieces of metal attached to the aft magnetic plug. I had my Mahindra dealer document what I found, when I found it, and where I found it.....just in case something bad happened down the line in time. It was still in warranty at the time. Now I have a few hours over 600 on it.

You have to find out if the blockage deadheaded pump flow. That means the flow from the pump had nowhere to go and would have had to bypass from the pressure side back to the suction side within the pump or else break the pump or its drive. Get a real no BS explanation from the dealer. If the pump was truly deadheaded, and nothing outright broke only because you were at very low rpm you may still have damage and could reasonably demand that pump and drive be replaced. If it turns out the pump was not deadheaded, and it was just forcing fluid thru the relief, I think youre OK.

I'm not a Mahindra mechanic and have never worked on one, but what it sounds like to me is that this "burr" hung up the spool in the 3-pt control valve. So when you moved the lever to drop the implement the spool was not moving, in fact it sounds like it was caught in the raise position and that would explain why the engine seemed to be bogging down. Since the spool was stuck it couldn't shut the hydraulic flow off to the 3-pt. I seriously doubt that there was any long term damage done to the machine, odds are that it has a relief valve in the system that would have prevented dead heading the pump.

So, I guess we can't name a tractor dealer when posting about our tractor problems, who would of thought.:thumbdown:

I told of my experience with my local dealer on here and wouldn't ya know it the owner called me after 9pm wanting to know why I said what I did on a forum like this. I'm glad she found the time to call because it took a lot of effort for them to call me when they had my tractor LOL. KARMA, that is all I have to say.
