I posted recently about the overheating problem with the 2320. I cut pasture grass from 3 inches to 12 inches from thin to thick ( the fel bucket was not hitting the grass in either case). I had the screen clogging problem in all cases except in the instance where I mowed my lawn. Keep in mind I am in West Texas and it does not take long for grass to dry out--the lawn is always watered so no dry grass in the yard.
My machine is now at the dealer awaiting a new motor. I have 24 hours on it. Had problems from day one which I was afraid was my fault as I had the heating problem from onset--attributed it to the clogged screens. After it was torn down, the dealer said it looked to be a factory defect from get go, so the clogged screens probably just added to the problem.
I was constantly getting off and cleaning the screens--more getting off and cleaning than mowing. How much of that was the defect, I don't know. Just know that I will be paranoid now, especially as someone else mentioned, the tractor has no temp gauge.
My opinion is that the mmm is useless out here unless you like to get on and off the tractor a lot or don't mow unless you catch it right after a heavy dew or rain. I do like the tractor and actually bought it to mow under my oaks at my place in the hill country (Texas). It gets dry there also, but is muich wetter than here in West Texas.
I thought of getting a RFM, but not so sure that will work on some of my pasture acreage ( am getting it ready with MX6 and 5203 but is a bull in china closet) . Maybe an LX-5 and sharpen up the blades. Have not figured that out. I just want a more finished look on some of our "pet" acreage than the MX6 will deliver. Again, the 2320 will be my tree tractor.
That's my experience so far, but like another poster said--there's a bunch of them around that have given the owners no problems. I just think it is a function of dryer climate and dryer grasses.
I too shut off my tractor if I am off more than a couple of minutes or so.
Best regards,
