John Deere GT242 Will not pull up hill

Hi,



I have a problem with my GT242 John Deere. We have had it since 1996 and I must say it takes a licking and keeps on ticking! It now gives me trouble when I first start out. I have to give it a little push to get it going forward. Once it is moving I can mow unless I start up to steep a slope. Some of these slopes are not very big. Does anyone have any ideas?





Thanks for any comment,
