I am considering buying a John Deere 2520. The transmission has a high and low range (no mid range). I will be getting a 62D mid mount mower as well. My question is whether I can mow at a reasonable speed in high range ....or do I need to be in low range for the power when mowing. I have thick grass in my lawn. When test driving the tractor, low range wide open seemed s little too slow. Said another way- what range do you use for lawn mowing on a 2520- low or high? Is power an iasue at the mower deck?
