1705 vs 1715

[gunner76]

I went ahead and told my local dealer to put my name on one of the 1715s with loader and mower when they get there next shipment of new ones in, they told me it would probably be in a week or two. He quoted me $16600 OTD which is about standard for my area. I could've saved around $500 if I wanted to drive three hours to a bigger dealer but for something like this I'd rather stay local in case I have issues and need service work.

So in a week or two there will be another new owner/operator with smiles all over the horizon lol

Are you financing. . What rate was offered? What size mmm ? What implements might you be considering ? Hope you have a good camera. Lol

Congratulations! I'm sure you will get a lot of good use out of it. We need photos!!!

I'm going to finance half of the purchase price. I could pay for it all but with the low interest rates there's no reason not to finance for a couple of years. The dealer quoted me 3.9% for 48 months and I would get the $1700 rebate(included in the price he quoted me) or I could take the 0% and lose the rebate. I'm going to take the 3.9% and finance it for 48 months which will save me around a grand over the 0% if I let the loan go the full duration. I'll probably end up paying it off next year after tax time. My bank wants me to finance it through them so I think I might be able to get the interest a little bit cheaper if I push them.

I'm getting the 60" MMM. It's way over kill for the double lot I have but since I'm already getting the machine for snow removal I just as well get the MMM and get 12 months use out of it. It'll probably only take me a 1/2hr to mow my lawn with it. I'm sure the neighbors will think I'm crazy(or rich)for using a diesel powered MFWD mower for a city lawn:laughing:.Only implement I'll probably get right away is a rear blade, I'm considering a tiller but I don't think I could find enough gardens to till to justify having it. Depending on how well the loader treats me for snow removal this winter there could be a snow blower in my future.

...it seems that with diesel engines the torque is maybe more important than horsepower.

There is no way to "measure horsepower". The only power metric you can measure is torque. HP is just a way to express the work of torque and is actually a very simple formula, i.e. torque x RPM x constant.

IOW, if a torque "curve" is relatively flat all you need to do to get a higher HP number is increase RPM. From everything I can tell this is what M-F did to get more HP and pump flow out of the 1705. They did change the injector pump, because the one used on the 1705 was at the borderline of being able to provide enough fuel, and the higher RPM/HP required more than it could keep up with. The hydraulic pump on the 1715/1720 is not bigger or more efficient, it simply turns faster, which provides more flow.

Bottom line is, if you run a 1705/1710 and a 1715/1720 at the same RPM (up to the max 2750 or so on the 1705) you will get the same HP. The only reason you get more HP with the 1715/1720 is because they have allowed it to rev higher (3000 RPM).

One major difference is that the gearing of the PTO is different between the 1705/1710 and 1715/1720 so that the PTO output remains 540/2000 at the rated HP. So even though you will be generating the same HP at, say, 2600 RPM on both variants, your PTO speed will be slower on the 1715/1720.

FWIW, the HP rating on the 1705/1710 (which is the same on the 2300/2400) is at 2600 PRM, but according to my manual the High Idle of that engine is 2660-2760. So assuming the torque curve is still pretty flat at that point (which, barring fuel starvation because of an inadequate injector pump, it must be, based on the 1715/1720 numbers) the difference between 2760 and the rated 2600 is just over 6%. So if your 1705/1710 came from the factory tuned at the high end of the range (or you get your mechanic to do so) you will be roughly halfway to the rated HP of a 1715/1720. Again, the major difference being that, if you are using PTO powered implements, their speed will also be proportionately higher. Whether that makes a difference, good or bad, may vary. But it's pretty good as far snow throwing goes

Im in the same situation you are, trying to decide between a 1705 and 1715. Im looking to buy with a mid mount mower and front end loader

Only one current fel available - but there are at least 4 mmm options regardless of GC1705 or GC1715

Greetings,

As stated in more than 1 thread, I've seen too many times where a poster has said that the 22.5 hp engine found in the GC1705 and GC1710 is the same engine as the 25 HP engine found in the GC1715 and GC1720 and all it is is just RPM increased. And I've said I didn't believe it. We've also seen some posters who claim that the part numbers of the components are identical and again I stated there was no logic to having 2 sizes of units that were identical if they were priced differently.

So nuts, I contacted AGCO directly to ask. Here's what they sent me:


- - - - - - - - - - - - - -

Both 23 and 25HP machines are built to spec according to the load transferred through the drive lines and the rest of the tractor frame. Both models utilize the same engine, but in order to accommodate more HP, minor fuel injection adjustments are made by MF certified factory technicians. MF does not condone, nor will it support, any machine that has been modified from the factory spec.

Thank You,

I take that to mean:

1. there is a difference in injection and it is not just altering the governor to increase existing rpm

2. because of the difference of hp and torque created in each size - the drive train and frame are altered to accommodate the differences in hp and torque. That could mean heavier/thicker metal or it could mean different grades of steel/alloys to handle the hp and torque issues.

3. it also means altering your GC1705 or GC1710 to increase RPMs is explicitly not supported by warranty, because #1 and #2 above are different for the 22.5 hp engined models compared to the 25 hp engined models.

How much difference does 2.5 HP make, is it worth the extra $$$?

I can only tell you my opinion - I wanted - the cockpit layout, sizing, and "fit and feel" of a Massey GC1700 with the best seat and strongest engine and pumps I could get in that size of unit. I also specified I wanted the DL95 loader because again - I wanted the greatest capacities in the specific size of the GC sub compact. So to me - it was definitely justified to invest just over $1,000 to accomplish that. And I can see the difference in fel lifting power between 2500 rpm and 3000 rpm with forks and payload capacity. I can see it in grass cutting deep grass. And I can imagine it would show up in 3pt pto output if I was digging holes or tilling.

My point is not that the GC1705 isn't a very good machine - my point is for just over $1,000 more I gained more power and more comfort without having to get something too big for my needs (different size tractor or different brand that I didn't like as well). I knew my needs of steep hills and slopes and a desire to do many things on a well kept lawn without tearing it up or sacrificing stable handling. Just my opinion for my needs. That $1000 over a period of 10 years is what 1 beer a week less LOL.
