Sorry to beat this to death but I'm confused regarding 2320/2520 performance. I've read through many threads now and here's what I come up with:

While the 2320 and 2520 are only a couple hp apart, the torque difference is more significant. From what I've read the 2520 has a 10-11 ft/lb advantage.

Both tractors use the same trans so the 2520 with its bigger tires has a gearing disadvantage to the 2320.

Some have said the 2320 may possibly be a little underpowered. I find no comments of that for the 2520, in fact, most have commented that the 2520 has plenty of power.

The kicker here is that I see posts commenting that the 2520 has an issue mowing in high gear. This is very confusing to me because the impression I get is that the 2320 with its gearing advantage and lighter weight (about 200lbs) does not have issues mowing in high. However, the 2520 has had complaints.

So which machine is underpowered?

I understand issues of gearing and weight; I've spent many years working with race cars. However, to me a vehicle that can't use high gear on anything but flat ground is just plain underpowered.

Why is the tractor that has some thinking it's underpowered, had no complaints about mowing speeds?

Why does the tractor that most think is adequately powered have complaints about inability to mow in high gear? To me, this means the tractor is underpowered.

As I said, not trying to beat this to death. The dealers are not much help. The dealer that has a 2320 in stock is obviously telling me how much better a 2320 is. He says he only stocks 2320s and 2720s because the 2520 does not provide enough of a performance advantage over the 2320 to warrant the cost. The dealer that has a 2520 in stock says the 2520 is a much superior tractor, and does not stock 2320s because he says it does not provide enough of a performance advantage over a 2305.

The 2320 has fewer threads/posts with complaints or issues. Oddly though, I found no threads where people have bought a 2520 and wished they had bought a 2320. On the flip side, even though the 2520 has a couple issues (gearing/tire rub) I read some threads where people have bought a 2320 and either wished they had bought a 2520 or actually traded the 2320 for a 2520.

I am familiar with the 2520's hyd system advantages. I am mainly looking at each tractors ability to mow, tow, move snow and transport loads (bucket). I want a tractor that has adequate power to do these tasks and not feel like I got an underpowered tractor.

Just driving these tractors around the dealership gives no real feel for what they'll be like working.

Should I only be considering what work can be done with these tractors in low gear? Is that where the comparison is coming from? I understand this is where a majority of the work is done, but as mentioned, I worry about getting an underpowered tractor.

As a person who is new to tractors, where will I notice a lack of power (ability) the most, and which tractor will exhibit this the most?

Thanks,

John

Hi JJKJ
I opted for the 2520 (still waiting for it though:()
The cost difference wasn't enough to outweigh the +'s.
I just made up my mind it was going to be the 2520..........period:)
Did you compare the specs on the two? There are more than a few differences.
I know what you mean about the high gear thing. I've been reading this everywhere. Frankly,it doesn't bother me. Ten owners will give you ten different stories. I will find out for myself. When its stated it (2520) can't cut in high gear.........How steep is the hill?....How fast are we trying to go anyway?
Are we trying to break a land speed record for cutting grass:)?
How tall is the grass?...Is the grass super wet?
Hopefully some of the 2520 owners will chime in for you.

Funny, because I've read many posts saying the 2320 is also geared too high to use high range when mowing. I think it all depends on who you talk to. A lot of people here would have you mowing one acre with a 3000 series.
No doubt the 2520 has better hydraulic response, but I think it is a little heavy for mowing a lawn.
Myself, if I were needing anything bigger than a 2320, I would buy a seperate lawn tractor for mowing.

No mower on my 2520.


I wish my trans had a middle gear.
Hi speed is often too fast for bumpy terrain.
I've spilled a load or two of firewood or gravel out of the bucket. My fault.
I think a lot of complaints about high speed is actually a wish for a middle speed.
If I were mowing, I'd want a whole range of speeds to meet cutting conditions. If I were only mowing I don't think I'd even consider a 2000 series, I'd look at mowers.

I'm ripping up old foundations, moving gravel fill, digging up and moving boulders and digging trenches .
Once all my digging projects are done, I'll probably sell and get a quad and a trailer. Maybe a plow blade along with the walk behind self-propelled snow-blower.

We don't get enough snow often enough to justify a plow or blower and keep the 2520.

I have never seen a 2320. I tested a 2305 and a 2520.
I also had quite a few 3000 series owners suggesting the 2520 would be too small for my projects.
It's been fine.


from what I've read here from 2320 owners, a 2320 may have sufficed. To know that I'd have to compare the hydraulic speeds.
From what I've read here from those that have tested both the 2520 was probably my best bet. I only get Sundays off. Seat time is nice, getting things done (faster) is nicer.

Maybe part of this is my misunderstanding how the HST works. The way I understand the operation is similar my X500. For instance, with mowing, you set the engine RPM at rated PTO. You place the HST in either high or low depending on desired top speed. If you place it in high, you can fluctuate your speed from 0 to 13mph with use of the fwd pedal. So lets say I want to mow at a speed slightly higher than low's top speed of 4.5mph. What/where does the problem occur with trying to mow at say 5mph in high gear on a slope? Is the tractor unable to climb even a slight slope at that speed in high? Does the engine begin to bog down or does the hydro just whine a lot?

My X500 would climb the hill I need to mow with the mower engaged. Engine rpm did not bog down but the HST did whine a good bit. If this is the only issue I'd have with the 2520, I'm not really concerned. This hill I'd obviously mow in low with the 2520, but the remainder of my land does have a slight slope. Will the 2520 be fine on a slight slope with a 62" MMM if I were to want to mow slightly faster than the low gear range?

Back to my original question--it seems to me if this is the case, then I would interpret that as the 2520 being underpowered.

I am just trying to understand the short-comings and strengths of each tractor.

Greg, you bring up some good points. It's almost as though you have to buy the thing and use it for a few months in different scenarios hoping you made the right choice. I just hate making a costly mistake.

Thanks,

John

I wondering if you shared with us your vision of what the tractor will be required to do, which are most important and how large an area you plan to mow, if that would assist in members providing input.

For example, if the tractor will only go 4.5 MPH in low range and you only mow 1 acre the time difference may well be minimal. I rarely go faster than 5.5 - 6.0 MPH at the best of times.

What's the heaviest load you anticipate having to lift? Will the hydraulics handle the load? How high does the FEL need to lift? Will you ever want a snow blower? a Back Hoe? Ground engaging 3pth attachments?

Not to be silly - but is this going to be a giant yard toy for a big boy - if yes and $$$ are not a big problem & you like that size tractor - buy a 2720 - then underpowered mowing will not be a problem.

I agree, it really boils down to how much do you want to spend. The 2305 will get the job done but it has slow hydraulics and no true 3ph position control. Move up to the 2320 and you get 3 ph position control and a pretty good mid-mount position control but not any better improvement in hydraulic speed. Move up to the 2520 and now you have something; good power and good hydraulics. Move up to the 2720 and you have all the power you could ever need in a tractor this size, I guarantee you will hardly miss the 3rd range.

I have a 2520 and will probably move to the 2720 this summer just for the extra power. I like having just two ranges for loader, it seems I'm always mis-shifting on my 3 range 3720.

As I understand the OP has a new 2305 right now, his prior tractor was a 2320, he is now considering going back to a 2320 or 2520. His main use from looking at an overhead view is mowing. Maybe some small jobs on the open 8 acres.

I suggested as others have to look at a 748 and 749 mower, and suggest that the 748 may be the better choice if the 3 pt hitch is useful to him. It has one gear range in the middle of the low and high ranges and has a speed range between 0 and 8.5 mph. Still think this would be a good choice if you do anything. If it were me and had the 2305 I would make do for awhile to make dead certain what I wanted.

If were starting from scratch and already knew for sure that a 2000 series tractor was the perfect size for my jobs then I would get the 2720 and not look back. Rarely if ever do I hear complaints from owners who buy just a lttle more power in a given frame size.

8 in 1 tools are never as good as dedicated tools, the same thing goes for tractors and mowers. When you buy a tractor small enough to mow the lawn then it isn't big enough for heavy work. You have to decide which is more important for the present, maybe an older larger tractor later for other jobs would suffice too.

I couldn't see buying a 2320 when the 2520 has so much faster hydraulics.
Also 2 more HP, and a TON more torque. The 2520 is direct injected, and I'm not sure if the 2320 is, but I don't "think" it is.
