I'm having a hard time starting the tractor on cold mornings (overnight low sub-zero, teens to twenties when starting the tractor). The glow plug light comes on, but on for 5-10 seconds. The engine turns over strong (the battery is good), but doesn't catch - just belches black exhaust. Typically takes 2-3 cycles of this to start. I've tried multiple cycles of turning the key to trigger the glow plug timer, but the light stays on only a few seconds on the second or third try. On my Gehl skidsteer with a Kubota engine the recommended glow plug time was 30-45 seconds at these temperatures - much longer than the tractor is timing.
What should I try next?
I've read numerous references on the forum to a decompression valve, but can't find anything about it in the operator manual. Does an L4630 have a decompression valve?
