Only Cub Cadets - New member from Pennsylvania

Hello and thank you for adding me!
I have been into the garden tractor scene for a long time now but I’ve recently
Started working on the cub cadets.
I have had a couple in the past but I didn’t keep them.
Currently I have a nice original condition 125 a nice original 128 and a not so nice
But running 147.
Both hydro tractors have issues with the hydro lever that I will start addressing
First. I don’t have much experience with these machines so I’ve decided to come
Here for some expert advise!
Also my 128 has a very sloppy gear shift lever.
It will be lots of fun to get these cubs into good working order.
I think the 147 will be my primary work horse being it has seen better days but
It does run pretty good.
Anyways thank you for taking the time to read my long winded intro!
