Mahindra 1533 slow hydraulics?

sirbendingo · Dec 4, 2015

I'm new to the modern world of tractors. I just purchased a Mahindra 1533 shuttle and I'm at the 10 hour mark. I bought the tractor for my part time arborist bussiness,
I'm waiting for the ground to freeze before I can really work it on a job. I have been doing odd tasks around the homestead and noticed that the bucket curl seemed to take a while. The specs say 2.6 seconds, but a full curl seems to take 6 seconds. Also the power steering seems week too. RPMs @2400.

I did have the dealer install a diverter for a Frostbite grapple (curl and grapple). Maybe that slowed the flow to the curl?

Do I have the specs wrong or do I have a problem?

Higher rpms will increase response time for the hydraulics. 2400 should be high enough. Are the lines bled for air? Check the hydraulic fluid level.

I'm not sure how to bleed the lines, but the level is good.

I'll get to work checking screens/filters ect.

FULLY cycle the cylinders 10 times. This should get any and all air out of the cylinder and lines.

The diverter should not slow the curl function at all, even if they did install a restrictor for the grapple which there is no need for, it should not affect the loader curl function.

I'm thinking that there may be other problems, does the loader lift at the correct speed? Is the oil warmed up? It will be slow if the oil is cold. Be sure the oil is warmed up and time the loader functions then.

Good luck.

Do you happen to have a remote function lever engaged ?

Sorry for the delay. I cycled the hydraulics and it helped! All four functions of the loader are running at around 4 seconds. A little slower then spec, but dosen't seem too bad. I did also notice the bucket dump function actually dumps slower if your fully engage the lever. It's like it over travels a bit.

My test was at full governed engine speed, and after running the tractor for half an hour or so.

Still suspecting weak hydraulics, I hooked into an oversize rock to see if I could get the back and a lift up and it wouldn't. Should it have? I've got loaded tires and #300 box hanging off the three point hitch.

You will find that with a loaded bucket, the loader will dump faster when the lever is full right, but only when pretty much full and I'm talking about weight wise, not volume. As far as the 4 second speed, don't know what to say. I don't think that your tractor will pick the back end up with the tires loaded. Have the dealer double check the pressure setting just to be sure that it's set where it should be.
