||I was wondering if someone can tell me why my 4440 is so hard starting. It runs great when it starts has 7000 hours, but is a bear to get started. It revs up to about 1200 rpm for a second or two then idles fine. Is that normal? It will always start without ether, but takes a lot of cranking. Any suggestions would be greatly appreciated.
||When you start a tractor with an inline pump the fuel rack is positioned to give it more fuel than at idle. After it is started the aneroid pulls it back to idle. Have you done a compression test to see if all cylinders are within 25-50 psi of each other? Have you set the valve lash? Are your batteries in good condiction, and how old are the battery cables? What does the starter sound like? Also at 7000 hours it might take some cranking to get started.

||Thanks Ross, I'll check into the starter first. I have been suspect of it for a while, because it seems slow turning. I put in a new solinoid, and new batteries last winter. The starter is a 1988, so it has been changed, but 88 was a while ago. Or it could be the cables yet, the starting got way worse when I hooked up my bale command system this summer. I hooked the positive side to the battery cable at the solinoid.
||My 4440 has 10000+ hrs on it and starts great summer or winter.Sounds like metering valve in injector pump or possible back pressure from hyd.pump if your starter and batts are up to snuff.
