I have a JD 2950 with what at first seemed like a starter problem, new starter,batteries,and cables later problem continues. Usually [but not always] on cold starts [summer] the starter struggles to turn engine over, acts like low battery condition. My neighbor has similar problem on 2955 and 400. Someone told him that it could be a injector pump timing advance not retarding. Could this be the problem and is it something I could deal with myself? I'm definatly open to suggestions this is getting expensive and annoying.

the easy way to check if its in the hyd is while the starter is engauged turn the steering wheel left to right as quickly as possible, ive seen our neighbors do this on their 4010-4020-and there 4430, ive seen them rolling over like the baterry was dead and when they turned the wheel they gained rpm on the starter and started

-What are the warm/hot starts like?
-Doubt that it would be hyd pump. most tractors don't have cut-out solenoids and they start just fine. Your oil pump doesn't drag on the starter, does it?
-Same goes for the injector pump. That's like saying the distributor on a gas engine drags on the starter. Only if the gears are misaligned and jammed.
-Have you tried jumping it from your car or truck battery when this problem occurs? How does it respond to a pull start?
-New batteries,starter,cables. Does this model have a separate solenoid(relay) or is it part of the starter?
-Don't discount corroded/loose/cracked wiring. I've found several instances of this each time the FORD 2000 Industrial would groan when I tried to start him this summer. Just enough current to make it barely turn over. Loosen some connections and wire brush them, re-tighten and VAAROOOOM!!
-Consider loose connections at or internal to your starter switch. Next time it does it's trick, bypass the starter switch and use a jumper cable to make the connection on your solenoid or starter.(Normal precautions in mind).
-Lastly, if nothing else works after you've talked to a DEERE mechanic, jack up the batteries, disconnect them, drive some other color tractor under them, re-connect the batteries and go on enjoying tractoring the way God intended. We won't think any the less of you for switching brands. GOOD LUCK, Jim

Does the main hydraulic pump have a destroke solenoid on it ??? As one of the other gents stated it sounds like the pump is trying to build pressure while its cranking over...There should be an electric solenoid mounted to the pump that doesnt allow the pump to build pressure while cranking. When the solenoid fails or the wiring to it...It resembles a weak battery condition..

Did you try removing your starter and cleaning where it bolts up? Most starters that ground through the nose cone never get checked like the battery cables do. Also you have to have correct guage cables for the amperage draw of a deisel, should be 1ga at least.

New starter, battery cables, and batteries. I've been through the connections with a fine tooth comb about 6 times. I don't believe its an electrical problem. Everything electric checks out fine. Hydraulic is a possibility though doesn't feel like a hyd. problem but I'll definately check that next. Thanks for the suggestions.

All the comments below are good. However, a poorly operating injection pump will cause a major headache too. On my GM truck, the pump's failure to start properly destroyed the starter too. So don't overlook it as a problem. Check out the electrical as the guys suggest, and if still problems, the starter may be dying due to overloading, and the pump may be the ultimate cause. Sorry for being the bearer of bad news!

i wouldn't know a jd 2950 from a lawn mower but i would bet your problem is electrical.... cables , batteries or starter ....i have seen bad new batteries , cables and starters .

Its summer time. Check battery cable ends for corrosion. Both at the post and if you used new cable with ends pinched on look for bad conection there too. If you made your own cables with the battery ends that you tighten the 2 bolts and strap down to hold the cable check there too. ALso check for good ground connection and at the starter too. Seems that any humidity at all will make them go nuts even new parts. Made lots of money one summer running around redoing battery cables for people

Check using a analog voltmeter or a digital set for only one digit to the right of the decimal. Dig one probe into the starter post. Not the cable or lug. The other probe into the starter's cast body. Anything less than 10.5V is poor.More than .2V less than battery voltage is cable/connection trouble. Test the battery(s) by poking the probe into the battery post. Test each battery by it's self. If less than 10.7V the battery(s) are weak. Seen several of these 12V parallel systems starting off one battery and the other just along for the ride. Also seen some good clean looking terminals with high resistance too

The problem is most likely caused by the main hydraulic trying to pump while cranking. The tractor may have an internal hyd. leak, bad or incorrectly seating stroke control valve, or main pump leakage. Try moving the steering wheel side to side when starting and see if it cranks easier. If it does, post back and we will go throw a test proceedure for the hydraulics.

injection pump will not affect starting speed.
as suggested, if problem exists after some houres of engine off (like overnight), maybe current is 'stolen' from the batteries. you can disconnect batteries (-) cables for the night and see if it helps. another thing can be loading of the hydraulic pump due to internal leak in the high pressure system. you can move steering wheel swiftly left and right while starting and see if it helps.

Maybe there's a leakage/short that's partially draining the batteries overnite. Is there a kill switch of the batteries to the electrics? If not you might think about installing one. Just a thought-I'd hate to get into the injector pump stuff before checking the electrical side first. Hope this helps.

My 3155 give me starting trouble one time and it was the flat braided ground strap where it was bolted to the tractor frame not grounding good it has 2 12 volt batteries in it if you have 2 12 volts you can unhook one and see if it gets worse if it don't crank at all with one battery hooked up then double check connections when it is warm that tractor should start with just 1 good battery but if 1 is a bad one new or old it can discharge the good one
