Hey guys; What is the part number of the blade that you guys are running is that the one that is mounted on the Front 3PT hitch? The reason I ask is that there is a 66" blade and a 74" blade that I saw, and I want to know what part number is the 72" blade?

Stupid question:
I was at the dealer the other day and noticed something on the 2520 that I never noticed before.. The rear axles are offset. That is each axle goes into an assembly, the assembly would contain either gears or I suppose even a chain then it goes into the transmission. This is instead of the shaft going directly into the tranny and differential housing internally.
Question:
Wouldn't this type of axle assembly be weaker (by being cantilevered) instead of one that had bearings on the outside and on the inside (inside the tranny holding the diff pinion pumpkin.)?
Also, does the 2720 have the same Setup? (The 2305 and 2320 do not).

Those are called gear reduction housings. Used also to gain more ground clearance. The 2720 has them also, as do most tractors...even very old ones.
One of the reasons I did not buy a 2520. I would also assume the setup would steal HP.orlo said:
A few things on the 2520 that would steal HP so buying just for the so called more HP over the 2320 made absolutely no sense to me. I read about a lot of people that bought into the more HP marketing on the 2520.

I'm not sure about HP as a reason for buying a 2520 over 2320 - I think it is more an issue of hydraulics and the fact the 2520 has better hydraulics than the 2320 - at least that was the reason I bought it.

There will be a bit of parasitic loss in any driveline component, but you have to get the overall motor speed to tire speed gear reduction from somewhere. It can be in the tranny, diff R&P, outboard gears, or smaller tires. My 5303 has planetary gearsets after the rear differential.Gizmo2 said:
Old AC ag tractors had big outboard gear reduction hubs like the 2x20 tractors, and my Unimog had portal axles which had about 2:1 reduction gears in them. The only odd thing about these outboard gear reduction gearsets is that the rear axle spins backwards from the differential. That just seems wrong for some reason.
I guess what I'm saying is that I don't think you lose any more horsepower from a geared hub than you do from any other contemporary driveline.
