bought a mz2552 this summer and loving it. my only beef is traction but my yard is only a year old and spotty at best so there is alot of exposed sand and some hills so i assume this will only get better as my grass fills in.
I bought the same mower and have a lot of hills. The mower had a hard time at first with spinning on hills and rough ride. I let air down in drive tires(I looked up minimum air pressure in manual and thats where I set tire pressure) and ride and grip improved dramatically. I can now mow hills that my 2 wheel drive tractor would not mow.
almost end of mowing season and now that i am gettin some grass i love this mower, i actually loaded the rear tires with -20 washerfluid which helped alot, this winter i am going to add some more weight to frame to try and lower center of gravity more but for the price this has been a great mower.
