Louise, TX | Our case rep worked for the testing grounds in Arizona during the development of the 71-89 series magnums. He said that if the engineers at the testing grounds said something on these tractors needed improving they got it. He said during the MX 270-285 series of tractors the penny pinchers at corporate would try to shave costs off of these tractors (IE SORRY HYDRALIC HOSES) which has reflected in the reliability of these series. These tractors are also Tier 3 which has 15% of exhaust recirculated through the engines which has also caused reliability problems.
He said Case's goal is to get the reliability of the 340 series magnums up to a higher level then even the 71-89 series tractors. By going back to a Teir 2 engine (preemission) and DEF that should at least make the engines more reliable. The Iveco engine has been out since 2004 in the 8010 combines with no major issues.
I have 7250 with 9000 hrs overhauled at 8000 due to head gasket leak, other than front planetary seals no other problems. I have 8950 with 8000 hrs and other than rear axle and planetary seals have had no major problems.
I have 2002 MX 270 with 8000 hrs spun main bearing at 7000 hrs replaced engine, and 2 injector pumps no other issues with it (was main plowing, planting tractor for 10 years never let me down).
I had 2001 MX 270 with lots of problems 100hrs ruined a piston due to slag in head. I replaced 4 injector pumps (3 under warranty), overhauled engine due to dropped valve, and lots of hydralic hose problems. It did pull a 13 yd dirt pan for 10 years in off season. Traded it on 2011 340 Magnum.
I have 1200 hrs on 340 so far and only that I have done to is is replace 1 valve for number 2 remote (under warranty).
Here these tractors are proving to been very reliable, there are still alot of issues with the 305-335 series here. The reason I bought a 340 over 335 is I wanted to get away from the emmission stuff on the engines.
