After a lot of reading this is what I've found. The Zetor power steer can use either ATF or STOU. ATF is preferred as it's viscosity remains constant when outside temperature changes. STOU tends to get thicker in cold weather making the power steer less responsive. There is a simple metal...

The other 6745 appears to have STOU in the power steer tank. Is that an acceptable option ? Just wondering why someone would have put that in. If I'm to drain the STOU and put ATF in, are there any special tips for draining and refilling ? There is only a very small amount of STOU in there, so...

I've got two 6745's here. One appears to have red ATF fluid in the power steer reservoir (sitting in front of the radiator) and the other has a clear oil (perhaps STOU). Both are low and need to be refilled. Keen to hear other people's recommendations as to fluid type, filter location.

My 6745 steering doesn't feel very good. First check is to look at power steer fluid and replace. But I have no idea where to start. Does the power steer system use standard STOU oil (same oil that goes into trans & engine) ? Where do I drain, refill power steer fluid ? Is there a filter that...

Time for a transmission fluid change. I've worked out where the hydraulic pump is (under the cover beneath the tractor between the rear wheels) and that there is a filter as part of that assembly. I assume I drain the oil, drop the pump off, replace the filter, reassemble and refill with oil...

Can anyone identify this Zetor for me please ? http://imgur.com/a/rqpgH It's not being loved, parked in someone's driveway nearby. I was thinking of door knocking them to see if they want to sell it. But thought it would be good to know what it is first. It's been repainted, so original...

I bought a used hydraulic pump out of another Zetor. Had to remove it myself, cost about $US30. Unknown condition. Will fit it in winter. I've been using my 6745 all through summer to pull my Welger AP71 hay baler around and it works well. Plenty of power to run the baler. Lots of weight &...

I'm slowly working through all the faults in an old 6745 I've just bought. Finally got it running and found the hydraulic pressure is low. It struggles to lift my disc mower and doesn't have the strength to fold it up (there is a ram on the mower plugged into a port on the tractor), even at...

I experienced similar problems in my Zetor 6745. It turned out to be a broken 4th / 5th selector. I would use the gear lever to put tractor into 4th gear, transmission went into 4th ok. Then would move gear lever out of 4th and into 3rd. Transmission wouldn't deselect 4th and would attempt to...
