Hello,

It's been touched on a few different threads here and rather than hijack those threads I figured I'd just start a fresh one dedicated to it. My 2014 Plat30 SHO has the 414 motor with the small trapezoidal tank and there seems to be a few guys with a taller square tank. Just saw some full size pictures of a 2014 28 with the 414 on another thread with the square tank. I started doing some web searches and found the pdf manuals for a Gen II AX414 manual stating it's pre-2014 and then the pdf for the Gen III AX414 stating it's 2014+ unfortunately the manuals use the same generic picture for the gas tank setup so no help there but the Ariens website has a bullet point list of the Gen III changes for 2014 and reference a new "low profile" design. So in the other member's case, it looks like his 2014 28" blower is sporting a 2013 motor on it that maybe the factory was using up the last of the Gen II motors before changing to the new design. Based on the placement of the oil fill tube between the two different tanks designs, I don't think I can swap tanks. Does anyone out there happen to have both styles at hand to physically look at, or post some detailed pictures of the square tank and oil neck areas? From the square tank picture, that oil fill neck is on the right side of the motor, mine has the neck coming from the middle of the motor so unless the square tank has a narrower footprint, I don't think it'll clear the neck on mine. I can't get over having the gas supply as such a problem 50 years after they started making snow blowers! That'd be like buying my brand new F350 pickup truck for hauling across the country and finding out it has a 4 gallon gas tank!

I would think that you could get the bigger tank on there, though you'd have to buy a few other parts to make the configuration amenable to that. You might also have to get the oil fill tube, perhaps some sheet metal covers, etc. Sounds like you'd also have to get a different muffler.

I can take some detailed photos of my machines for you if that will help, just have to wait until the weekend for me to have time.

Are you sure the older version is even any larger or just different shaped? In Ariens sales sheets both the Gen II and III claim a 2+ hour runtime. Its not that bad is it? I am not sure how long mine runs but, it doesnt seem that bad unless it is a really heavy snowfall. I guess a larger one wouldnt be bad though. On the plus side, the Gen III has other improvements which still make it the desired motor to have of the two imo.

This is why my "Dream" Ariens 24" SHO would have the 420cc Briggs and Stratton. Oh BTW it does have a nice 3 liter fuel tank. Guess I will have to
re-power my new SHO, (if I ever get lucky enough to have one) when I get it.

Despite having what some say is a bit of a small fuel tank(its not that bad imo), the Gen III AX414 engine is a better quality engine then the 420cc Briggs for a number of reasons. I dont think a larger fuel tank and one more foot pound of torque is worth switching to a less reliable engine with a much shorter lifespan. Just something to think about. Briggs arent what they used to be man. I think an aux tank or just sucking it up and filling more often is a better option.

I know this motor rocks as I've seen it in action also. It's good to know that the
the AX414 is good a engine too. It will be worth something when I tear it off and sell it and put the 420cc on.

And according a lot of reading I've done about lifespan of the two engines it appears you may have wished to keep the LCT 414 for after 150 hours or so of run time on the B&S.

I'll take my chances with the sacrifice of 6cc of displacement and 5% less torque if it'll last more than twice as long. Some estimates are more like 5 times the life.

takes me 4 hrs to clean the yard..and 2 tanks of fuel..I also clear about 8'000 sq ft...used a little more when the machine was new..but its at 2 tanks now..25 hrs on the machine..I really don't think that's so bad...after all when I bought the machine I wasn't shopping for a Prius..mine has a low profile tank

this machine also gives a fair amount of warning when it's getting thirsty I can tell 5 minutes before it runs out..I usually make sure I end up back at the gas can..let the motor cool a little while I clean and move the cars..fill'er up and finish the job

My 921029 with Gen II motor got just over 2 hours of run time on a tank the first time I used it. I can't complain about that, it was working hard on a deep snow and about a third of it was the compacted plow berms.

Pixman I also have the Deluxe 28+ (Special edition model) I have not used it I'm hoping that it is a beast I upgraded from the Deluxe 28 with the 254cc motor. I had a question does the oil drain plug on your AX414 motor have the oil drain plug terminating on the right side of the motor instead of facing the rear of the machine? If so have you had any issues changing the engine oil being that it is so close to the RT tire?

I have the Deluxe 28+ (special edition) with the previous Gen II AX 414. I was told by Ariens tech support that the fuel capacity on mine is 3.8 quarts. I do think the improvements on the Gen III outweigh the smaller fuel capacity, especially the oil draining to the rear this is a huge advantage in my opinion. By the same token I am surprised that they would lower fuel capacity on a 414cc motor. I know on their Pro series models They are using Briggs engines with a much higher fuel capacity, which makes sense for a larger engine machine. Good luck with your Platinum 30 SHO it is a really nice unit.

2 hr runtime? Not in a million years as far as my experience goes with this machine. I'd estimate around 30-45 minutes with it so far. I've got maybe 4 hours on it so far and I'm on the 6th tank full of gas. It's also a major pain in the neck trying to top it off. This gas tank design is horrible. I get a big kick out of Ariens description: "An easy to use, large diameter fuel cap" I guess they got the large diameter part right, but easy to use? HA!

Pixman, yeah, when you get a chance. I don't know about that oil fill tube just being shorter thing though, it appears to come out of a different spot in the top of the motor. Your picture shows it on the right side of the engine, mine comes from the middle of the motor.

I'll have to look but that won't happen until perhaps later today. I did say I would try and get photos of it for the OP.

I remember reading somewhere Ariens has the same size capacity listed for the newer unit as well, but a member here on one of the threads measured the actual capacity at 2.0 litres, and got 2.25 with it spilling over the top. I'm guessing they sacrificed the capacity to fit the low profile of the new design. I'm sure I could get a few more minutes out of it if it was just sucking and spitting powder, but I've been running it through a bunch of heavy stuff, beyond the standard eod plow mess. I've got one of those CoverIt car storage tents in the back yard and the snow shedding off the roof piles up on the sides of the tent. I need to go back there periodically and clear the sides of the tent to allow more room for additional snow load to drop. That stuff tends to get icy and you can hear the machine working the governor with the extra load so I'm sure it's sucking down more gas for the extended load work vs the average kind of snow out on a driveway. It's just getting a bit comical how many times I've run out of gas with it and had the long walk to the garage to get the fuel can.

Sounds like you've nailed the problem, OR the fuel just isn't emptying the tank that is actually carrying the full stated capacity.

Have you ever tried dipping a screwdriver or other inert object (which wouldn't foul the fuel with crap) into the tank when it runs out to see if the level is actually down to within a fraction of the bottom of the tank? Is it possible they have a stanchion of some kind the keep intake of fuel off the bottom where there might be sediment?

I understand it is certainly an inconvenience especially on a higher end machine. I am not so sure I believe that my GEN II AX414 has a 3.8 quart capacity, I think that may be optimistic. According to the LCT website, they show the engine on my unit with the exception being the lack of the throttle control on their photo, their specs show the fuel capacity at 2.7 quarts for the GEN II Motor? Even on my 254cc Deluxe 28, I seemed to be filling up quite often with the LCT stated 2.9 quart fuel tank.

My experience with Ariens customer support is they seem to shy away from engine questions often stating "we don't make the engines." Trying to deal with LCT is often a challenge, it is very difficult if not impossible to get a straight answer at their tech support line: 1-800-558-5402 for any question where the info is not readily available. I tried to get the thread size for the oil drain tube in order to put an aftermarket release valve to use with a plastic tube on mine for easier oil changes and was unable to get that info. In fairness to Ariens customer service/tech support it is arguably the best in the business. I always get someone on the phone usually within a reasonable amount of time and they really do try to address all of your concerns.

Additionally they seem to listen to their customers concerns for example a lot of people complained in their reviews about the newer headlight design blinding them as they used their machine and on my Deluxe 28+ I noticed they added a tinted upper portion on the headlight to address this from last year's model. That being said I believe if enough of us complain about the small fuel tanks on their larger engine machines they will address it in future models, unfortunately that won't help us who already own them. We shouldn't have to buy a $2100.00 unit to get the proper gas tank size. However we will then have to worry where they will have to cut corners to pay for the larger fuel tank..lol

The fuel tank empties completely, there is just a film at the bottom. I measured it with a tape measure and there is no depth to the remaining fuel. Add 2 liters of gas and the level is just over the top of the screen where the metal part is a larger diameter. Continue filling the tank to the bottom of the cut-outs where the fuel cap fits down into the neck with the strainer in place and fuel pours out at just over 2.25 liters and less than 2.5 liters. So in my opinion the tank holds 2 liters allowing for air space and avoiding gas spills that are not small.

The low profile tank is spec'd at 3 liters (3.2 quarts) according to Ariens documentation. My dealer has talked to Ariens and Ariens ordered a new tank about 2 weeks ago and will be measuring its capacity. Mary Lyn of the Ariens Company (user id on this site) is also looking into the situation.

While the shape of the prior year model fuel tank looks larger than the current I have not heard of anyone measuring its capacity. It would be interesting to learn what the measured capacity is.

Maybe you should fill up early, while your at the garage, instead of waiting till it runs dry and having to walk back to your garage.
