Are there any groups that have free help for senior grass cutting and home repairs OI would dearly appreciate any information I can get

If you can call any Senior Citizens centers near where you live... they would likely have that sort of information. Or could direct you to to someone that does.

There are also church groups that do small home repairs for senior citizens and more so in summer months when young folks are more available. Methodist churches I know do it, and many others if you inquire and check around.
