</font><font color="blue" class="small">( What is the differnce between the mf 135, 35 and TO 35? )</font>
TO-35 was the final stage of developement for the TO series whils still under the Ferguson Banner. When the name changed to MASSEY Ferguson, the MF 35 was borne. Very much the same as a TO-35, it was a HUGE seller. Then when the 100 series was introduced, the 135 made it's debut. Better hydraulics, better clutch, Improved handling, better all the way around, the 135 was a ledgend in it's own time.
All along there was a "big brother". FERGUSON F-40's and Massey Harris 50's were much the same as the 35, but with heavier front axle (more clearance/better steering) It had a bigger fuel tank, bigger radiator, 9" longer wheel base (due to heavier front end) (That front axle was actually "borrowed" from the bigger "65" and later "165") The 50 became the 150 when the 100 series hit the showroom. 150 packed an additional 500 lbs on the front end, combined with longer wheelbase, it made for a much better plowing tractor over the 135. (I'm CONVINCED the 150 was the best small utility tractor ever.)
For the beginner, a 35/135,50/150 would make a great starter tractor. Enough power to get the job done, simple enough to work on that a "shadetree mechanic" can fix almost everything, cheap to operate, relatively inexpensive compared to some other tractors in it's class, and the absolute cheapest engine ever to operate and/or re-build when that day comes. (That goes for the Continental gas engine, The Perkins Gas engine, but ESPECIALLY for the Perkins diesel )
Watch out for SOME 135's that were sold to compete with the Ford 2000 . They came with a bigger HP rating than the Ford because they used the same engine to compete with the 3000. But those 135 "specials" had no live power, 6 speed WITHOUT Multi-Power, most had no power steering, and some even had a "pan" seat.
135/150 sold for under $5000 at their end. (Under $4000 when first released) They still bring that much today in rough condition.
