MF 175 vs 275

[Bill VA]

Any substantial differences between these models? I notice the 175 has the 236 Perkins and the 275 has the 248 - anything to fear from either of these engines?

Thanks!

The 236 is 3 7/8 bore X 5 inch stroke, the 248 has 3 15/16 inch bore X 5 inch stroke. I've never tried it, but I think the 248 sleeves would fit a 236 block as one of the parts books I have shows the sleeve OD specs are the same. Both blocks look identical outside. Also, the MF 275 has a heavier flywheel than the 175 does. The 236 shares some parts with the 6.354, and the 248 shares some 6.372..

Thanks again for your help and info - very much appreciated.

I want to add another utility to the haying fleet and the 175 and 275 are of interest.

I use the next smaller series 165 and 265 for haying, both small squares and round baling. These are pretty similar comparisons to your question. I prefer using the 165 for raking and cutting. Sips fuel more efficient. The 265 much better round baling since hydraulics are better and more gpm and the 265 has more weight and "arse". Both 175 and 275 good choices, I'd decide based on condition and options. I believe the 200 series were easier to fit the front engine hydraulic pump which provides 17 gpm and works great with loader, as my 265 has that with the MF 236 loader which is solid set up. I'd suggest also considering a 265 if you see one.

The 265 replaced the 175. The 165 are good on fuel, but I'd take the larger Perkins 236/248 engine any day over the Perkins 203. Unless, you LIKE all that extra vibration the 203 has since that engine does not use the counter balancer like the larger Perkins four cylinder engines used. Dad had a row crop 165 diesel years ago, while it served well I'd take dad's 180 any day over the 165.
The early 255 also had the 203, and all the late models switched to the 236 that had a lower max fuel setting than the same engine used in the 265. Dealer I worked for sold an early 255, it shook just like the 165 diesels did..

Is their a power difference between the 236 and the 248 cid?
