Just purchased a new to me Bx2230 with 200+ hrs. and 60" MMM mower from my local dealer. After reading on this great site for a few days with all the available help I feel I can handle this tractor OK. Hope I can contribute after some learning. Retired with about 5 acres. Plan to mow about 3 acres. Of course I have a question!!!!. My engine (D902-E) temp gauge never goes past the very edge of the normal range on the cold side. Outside temp about 60'F and mower not running. Normal? Does it have a thermostat? Seems too cold to me. Thanks for any comments. Looking forward to mowing.
