I have a l110 and have had it for about 5 years , my tractor seems to not move forward as fast as it use to. I am not sure if it just because I am getting uswe to the machine , or is possible that it may need some kind of adjustment. Whem I enge the drive it still reacts as quick but it just seems to not have the same speed any more. I was wondering if the applly rod might need to be adjust , and if there is any adjustment , or am I just looking for something that isn't there thanks Peter

Hi,
At five years of age, it probably time for a motion drive belt. Check also the two idlers on the belt. JDAnswers has the following directions:
