AGCO ST22A is pretty much the same tractor as Massey Ferguson GC2300. The ST22A and JD 2305 have a 68.5cu.in. engine which is bigger than all other subCUT tractors. All other companies' subCUTs have engine sizes between 54 and 61 cu. in. The difference between JD & AGCO is the JD is rated @ 3,000 rpm while the AGCO is rated @ 2,600 rpm.
Other specs on AGCO ST22A:
Eng. HP = 22.5 @ 2600 rpm
PTO HP = 18.7 @ 2600rpm
2 range hydrostatic transmission with cruise control,
lift capacity @ hitch point = 1213 lbs.
wheelbase = 57.1"
overall length = 97.6"
width = 45.8"
ht. over ROPS = 72.4"
weight = 1367 lbs.
hydraulic flow @ remotes = 4.1gpm
Hope this helps!

Thanks. After doing some searching I finally figured out that the GC2300 and ST22a are pretty much the same tractor so I'm looking up posts on the GC2300. I noticed the RPM difference also and even noted that the Kubota turns around 3300rpm to get 22 hp. Don't know exactly what this means since I'm not much of a mechanic, but I do know alot of the older American made diesels turned alot lower rpms and seemed to last forever. Anyway thanks again for the info.

You're right, they used lower RPM, and lasted a long time. The newer smaller diesels made with different cylinder types and alloys should last between 5 and 10,000 hours, so I don't think you'd have anything to worry about.
I'm still fond of any engine that functions optimally at around 1800 RPM. Guess I'll always be, but I don't expect any less life from my small 21HP@2800 RPM.

The closer a manufacture goes in the direction of tapping more horsepower from a engine, the RPM will be turned up more. It most often is used when a few more hp is needed to market a new model. This is a larger cubic inch engine that can turn a slower RPM and still develop the hp currently needed for its model range. As competition increases, then the RPM will likely increase. A lot of the competing models are already at or near their RPM limit. As the RPM level is increased, the life span is decreased.
