Which is better?

I plan to buy a tractor.
1) XX tractor with 2.4L 4cyl diesel and it has 56hp.
2) YY tractor with 2.7L 5cyl diesel and it has 54hp.
Which one is better? What I know (I could be wrong) is the bigger the cylinder the better it is. Is it true? What about the horsepower? Please help? Thanks!

 

Are they different brands of tractors? Since the HP is almost the same, I wouldn't get stuck on engine size/displacement. The tractor having the features you need is more important along with availability of repair parts. I'd also look to see which tractor had the better reviews that related to the intended use.

 

Thank you, marksr. Yes, It is the same brand tractor. Kubota M5640 v.s. Kubota M4900. Since they're very much same, it is hard to choose. Go for Cylinder or Horsepower??

 

IMO I would go 4 cyclinder...

 

Don't we have dedicated forum for this type of machinery? I mean, I don't care, but dura lex sed lex.

 

Yes.. I moved it.... Just had to ask.. Very busy and cant catch it all...

And stop cursing UKR.............

Actually it dont make sense????....

dura lex sed lex = """"Law is harsh, but it's law"""""

 

I would first let the features and hours of the tractor decide. Almost hands down I'd go for whichever has 4WD. I would not consider the number of cylinders and the engine hp is close enough to not be an issue. The 5640 is newer and would have better fuel burn per horsepower. It also has 5 more hp at the PTO.

I had a number of Kubota's and currently have a L3710 which is from the same era as the M4900. I think the 4900 has steel hood components. The squarer shape blocks your view up close in front more than the modern fiberglass curved hoods. The steel hood, side panels & front are removable easy enough and can be pounded back out if you drop a tree on it where the fiberglass hood of the 5640 is pretty expensive to replace but could be repaired by an auto body shop. Personally I like the simpler analog gauges and fewer electricals of the older tractors but it's hard to not like the saxy, curvy newer stuff. Post back with whatever you decide.

 

Yeah, I think you're gonna be happy with either one of those. Look at the horsepower/torque curves and see if one has a noticeably flatter but high torque curve through the rpm or higher torque in the operating rpm than the other. If so, I might lean toward that one, but like I said, I think both are going to be better than sufficient. One has bigger pistons, the other has more pistons. Not much difference. The 5 cyl might be a hair smoother running but probably not noticeably.
