Yes but ...A lot of folks replace that screen with a pleated furnace filter or bulk furnace filter media. Much more efficient and easier to service.
What Tom told you about hydrostatic drives (not a "tranny") is only partially true. There isn't more maintenance issues. In fact there is less. Both my skid steer and excavator have hydrostatic drives. Very simple concept - hydraulic pump driven by a diesel engine and hydraulic motors, but the initial cost is considerably higher. That's the true part.
I think each of those points is valid in some circumstances but there can be other cases where a different solution is preferable.
For the radiator screen, wire mesh won't be damaged by backflushing with a garden hose. It won't keep the radiator fins as pristine, but a garden hose washdown at the end of the day without disassembling anything is quicker to accomplish than pulling and servicing a furnace filter.
For anything hydrostatic, the mystery fluids (hazardous waste disposal?
And for a tractor used heavily for pto work, mowing or tilling etc, the power loss in a hydrostatic pto is larger than a manual transmission. I'm thinking of the Mahindras where the difference in ratings is substantial. Seems to me all that lost energy in the transmission is felt as heat by the operator.
Hydrostatic is great if you need to change speed or direction all the time, mowing in close quarters etc. For longer runs, discing or tilling etc, I think manual is more efficient. Either has its place but the application should be considered in choosing which is preferable.
