I am new here so bare with me.. I have a JD 125 20hp (11 years 0ld from HD) and have had fairly good service with it. I am 73, 6'3' 250 lbs, and I have just about 3/4 of an acre of Bermuda and weeds, and on a slight hill in the front. Where I live I need to bag almost every time. I am considering a Cub Cadet XT1 46 or XT2 42. My question is, can anyone tell me which HIGH-LIFT blades on these two mowers work best. I want the Kohler 22 hp, because of my size and bagging. Thanks.
