Aranon,
I have heard turbo's provide more HP at higher altitude. Something to consider. Dave
Hi Aranon, welcome to TBN, first I suggest you review about 400 previous threads on this topic. That being said you know you have again opened the color wars!!
Now you should fill out your profile in full ,including the area you live. This will have a bearing on turbo V. natural. If you are above 4,000 ft you should lean toward a turbo engine if at sea level natural is fine and cubic inches rule, more cubes more torque.
Next we need to know what you plan to do with unit. Lots of loader shuttle work, and you don't have a lot of experience with tractors and clutches, go hydro or if no hydro in size class available then you want power shuttle shift. Why have you picked 50hp range? was it to run a 10ft bush hog? or handle 2-3000lbs loads with the loader.
1.will you be moving 2000# big bales?
2.mowing with a 10ft BHog
3.running other PTO equipt like a small square baler 7-8ft snow blower?
4. who will be running most of time, wife ,kids etc?
What do you plan to spend? What other equipment will you buy initially?
Before you chooose a color I'd visit evrey dealer near you. Ask farmers and other owners why they chose a certain brand? Ask the dealers for references?
How helpful have the dealers been in helping you thru this decision making process? If they are working for you and your future business and not just todays sale then they will help you with this.
Lastly my advice is pick a dealer you are comfortable with and that comes recommended.
Even if you have to travel a bit farther or pay $1000 more, in the long haul it will be worth it, when oyu need service, warrenty work parts etc.
All the brands are good, look at Massey, Challenger, Agco, Kioti, IH, Mahindra, JD,NH and more.
Good luck and keep us posted, Joe48.
