Well, i can't answer that. You see yesterday was the first time i have sat in the seat in 2 years due to illness. My son 48 and grandson 25 has used and maintained the tractor in my adsence. Now both are well versed in operating heavy equipment since it is their jobs. Using the tractor yesterday to move a pile of dirt i just had delivered it just did not perform the way i remembered. Today i talked with my son about it and he agreed with me. He had not noticed it since all he used it for was to use it occasionally to upload some lumber or to boxblade his driveway. I'll call my mechanic tomorrow and have him come out tomorrow and I'll let y'all know. Thank y'all for your replies!!!
