MF 6150 Transmission oil low pressure warning light

[Whistler]

While spraying on Sunday I had the above light come on. It knocked the PTO out, stuck in 4wd and put the dynashift to D. I finished the field at a lower pto rpm to get done. Normally run the pto at 450 rpm. The light seemed intermittant. Any ideas of where to start looking.

**The following is based on my experience with a MF 6265, I assume its the same arrangement for the dynashift transmission**


The switch that drives the 17 bar circuit low pressure light is number 6. It is on the right hand side of machine behind rear wheel. The switch number is 4358647m3 assuming it is an open centre machine, dealer price should be about £60.

If you have an M14 x 1.5 gauge bush you can connect a pressure gauge to it and see what is happening. Low pressure alarm annunciates at < 9barg. Transmission pressure gauge kits can be bought from eBay for £30 so cheap compared to a fitter having a look as a starting point to find out what's happening.
