To all familiar with the 210, I've been around various makes of older tractors, all diesel, and harder cold weather starting is always usual, but I feel like my 210 is worse than most I've been around. Inj. Pump redone recently along with new inj. Tips. Tractor runs like a top and tons of power once warmed up. Never misses a beat, but if not plugged in for several hrs or tiny sniff of ether at temps below 50f u can crank all day and get nothing but plumes of smoke. Is this normal on these tractors? Has #3500 engine, 2900 hrs on rebuild and totally stock

On my 7050 it was very hard starting. I figured it was the nature of the beast. A couple years later I put in new batteries and new heavier cables which seemed to help but not much. About that time my brother bought a 7030 and we had them parked side by side. I started mine then jumped in his but when I turned his over I noticed it turned over noticeably faster. I wouldn't have noticed the difference if I hadn't done the side by side starting.

When I bought the 7050 I got the whole history of any repairs tickets and it had just been overhauled, new block, crank etc, rebuilt injector pump and injectors AND A REBUILT STARTER. Just for the heck of it I switched the 7030 starter over to the7050 and what a difference! Had the starter rebuilt again and, although it will never start like any newer tractor it will start without being plugged in down to 30˚F or so. Might take a couple attempts now though but the starter also has 20 years on that rebuild.

I'm not saying that is your problem but it may be something to look into anyway.

Faster they turn the better they start. Recheck timing, retard it a couple of degrees. Like Lonn said. MACK

"Pump recently redone along with new injector tips". So, you know how it starts now, and you are complaining about it. How did it start BEFORE the injection pump work and new injectors??? What this oftentimes boils down to is this...….if it doesn't use any oil and runs well, how much money do you want to spent looking for the needle-in-the-haystack?? and which haystack is the needle actually in ??

Pump was redone out of necessity (governor went out) and since it was laid up getting pump done figured I'd pop test injectors while at it (always had tiny miss to it). But the tractor started just the same before as after. Pump and tips made no imp. Not really worried just wondered if this was just common or just mine that starts that hard

I'll bet once it has been started and warmed up, it will restart easily the rest of the day, right ??

My 220 started that way before overhaul. Sniff of ether was good help. At O/H found at least one broken ring on every piston. Had plenty of blowby but oil consumption was not excessive. Had good power also. M&W's cured everything. Makes one wonder if your starter is part of the problem? Any idea what brand piston kits were installed?

Steve has a good idea there. Check the compression. Low compression diesels start hard in cold weather. LEON

Similar to what was said above...Had my 210's starter rebuilt, New Alternator, Heavy Cables (2) Rural King group 31 batteries in 2008 and that tractor starts great. Those batteries are still going strong!! Tractor only gets 70 hrs a year I have never seen batteries last that long!

re: Low compression diesels start hard in cold weather.

yeah... my special, ultra low compression Buda 4BD153 in the forklift needs 3 squirts of 'get going juice', pedal to the metal, key to start until engine spins fast enough to run on 3 ,3.5 then 4 cylinders... blowby is blacker than the a coalmine when the lights are out.....

I was going to change the oils in it today, until Shamelesss machine was turned on again.....
