HRS, I have a 1433v with only about 50hrs /forums/images/graemlins/frown.gif, I don't use it as much as originally planned...but as for your questions:
The 33hp is plenty, what I don't like is the 8x8 trans even though the shuttle shift is great the ratios between hi & lo range are too wide(too fast or too slow). I would rather have the 16x16 shuttle or the hydro.
Weight wise , I think its OK , My rears are loaded R4's and it has a FEL so I think its around 3200+
The 1433 has a pretty tight turning radius which I like, But the tractor is only 60" wide which is fairly narrow and you sit up a little high which is good for loader work , But when you traverse a slope you get a little pucker factor .
I would also like telescoping lift arms because its a little tight trying to hook up implements with the 14.9 x24 R4 rear tires so close together.
I really don't have any other loader experience to compare mine against another , all I can say is ,it seems plenty powerful...Compare pump flow GPM with other brands...
Hope this what your looking for /forums/images/graemlins/cool.gif
