I have a 2007 Deere CT332 it dies when loaded and has poor performance. It has had a cylinder leak down test and passed, new service, new oil, filter, fuel filter, and the air cleaner was dirty and we are changing tomorrow. Any other suggestions? Drives and functions well, have to rev up to move but weighs 10,825! So I thought OK, but not performing well under load in the field. Please let me know, thanks!
