Max28 and cold Weather

What is weird is that these use exactly the same engine as the 3016, and no reports of engine starting problems come up with them.

What's the difference here?

Mine has the original battery, and last year I had dino oil in it and it never took more than a turn or two of the starter before it started. I even added a battery tender which I don't use.

This year I changed to synth Rotella T6 oil and it starts even easier.

Thats a good point,both tractors share the same engine. I wonder if the GP system is a little different. :confused3:

I tried starting a Max 26 and a 3016 on their lot and they fired right up.

I'll find out Tuesday if the changed the fuel and oil on my tractor. I don't think it will make a bit of difference.

As the have a Max 26, the dealer ought to see what the differences are between GP operation of the 2 under the same conditions.

If they both "glow" the same and have same voltage and heat up the same, its in either the electric pump or the injection pump.

To get red of me they could just transplant the 3016 engine and I'm happy.

the test would be finding a max 28 on a lot and trying it as it is tuned to exactly the same specs as the 3016. Even tho the 3016 is a model size larger, it has exactly the same 28hp engine as the max 28.

Re: Max28 and cold Weather, Dealer report.

I sent dealer an e-mail regarding troubleshooting my Max28.

He cal em this morning.

In my past reviews of my mew Max28 in this forum, I remarked that for a new motor, it always smoked and stumbled more on start-up than my 32 year old tractor.

I mentioned to the dealer that waiting a few minutes to restart often did the trick to get it started and expressed my doubts that it was a glow plug issue or GP relay, cranking speed issue, or due to thick lubricants.

Service manager personally reinspected fuel starting solenoid, verifying it was set to spec, still no start.

He then opened it up another 1/4 turn, and it started in 17 F weather.

He is going out this morning after it warms up a bit and fiddle some more with it.

He said backing it out too much will cause motor the stumble and stall. He will find that point and then adjust by observation where the motor runs best.

So I hope the issue was the engine was not getting fuel.

I plan on bringing it home Saturday.

I appreciate the efforts by the dealer, as I bought the tractor in NY state as no Max28s locally were still available and the Max 26 was near $2000 more, so it is not like I gave the local dealer any business.

I think I need to buy a few filters.

PS the Mitsubishi motor comes with an electric fuel pump to help with priming and gravity fuel delivery.

Many other fuel injection pumps have a mechanical primer built in.

I have just read through this whole thread, I have a new 2555 hst. Tier 4 with 50hrs. It will not start when it is low 20's or below. I cycle the glow plugs 2-3 times. Battery does not last long either. I then have to put a 400w magnetic heater on the bottom of the block and a 100watt battery charger. Sometimes it takes over an hour to get it started. I just purchased a Zerostart yesterday hoping this will help. I don't think this problem is limited to the max28's. I also was thinking that my oil was to thick.

Your new tractor should start, at least down to below zero. See post #85

Our RTV900 started/ran just fine, but then!

With the battery not lasting long does it still have the original battery in it and have you messed with the connections?

OK, The Earth's climate is going Flaky too!

Saturday -17F , wind Chill about -35F.
Today, 47 F , 60 Mph wind gusts. Very foggy.
That is a 60 F difference in 48 hours.

I think the Kubota RTV900 Hydraulic resevior vent lets moisture in the oil, and the system froze up. Equipment building is still about 30 F on the inside, and all the equipment is really sweating. That's not good, as the insides of the engine, etc collect water.

oldpilgrim · Feb 16, 2016

We went from -9 to 58 in the same time. That's 68 degrees in 48 hrs.

bluefin650 · Feb 17, 2016

Same Battery, the tractor is less than 9 months old to me. Connections on the battery are clean. When it warms up some, I plan on checking the ground to the frame.

Navasot · Feb 19, 2016

Definitely would clean the ground at the frame and start there.. iv had this solve numerous electrical issues.. from there the battery would be next. :thumbsup:

Here is what i have been told. The diesel shutoff solenoid was not working consistently. It was not getting a full pull and motor was not getting fuel.

Max28 is home.

Statrted fine at Dealership this AM, course it was 35 F. Not much smoke on start-up, that is good sign. We are supposed to get some cold weather next week. Hope it passes the test.

I left mine outside last night on a trailer. I've been using it at another location this weekend, usually I put it back in the garage at night because it is cold-blooded but left it out last night. Both to test the cold start and because I was exhausted when I got home. Anyhow, this morning it was like 28, I cycled the glow plugs twice and put the throttle to about 1/4 and it fired up first time. I pushed the throttle back down as it started and it smoked pretty good but it didn't take 5 times with the glow plugs and throttle all the way down.

Just an update, All seems well, Seems to start better than it ever did. Spring is here now, but it started fine in the teens.

bamboozled · Mar 7, 2016

Any chance you can elaborate on this? Did the dealer determine solenoid defect was related to temperature, like because of the temperature the solenoid wasn't opening as much as it should? Or because of the colder air temperature more fuel was required to start then what the solenoid was allowing to feed?
