I bought my TO30 in 1999 from a member of our local EDGE/TA group. I have spent far more hours maintaining and repairing it, than I have using it! When it runs, it runs well but these older tractors are for people who LIKE mechanicking more than someone who needs a tractor for actual dependable work.
It is a very powerful, low geared machine and I've pulled Manzanita stumps right out of the ground, and picked up ditched cars easily using its three point hitch. The 3-point hitch easily handles implements, the most useful of which is my scoop, hands down. The PTO works great with a good Bush Hog although it requires an adapter.
The problems with it were: fuel tank (replaced it with a plastic ATV tank), carburetor (cracked and leaking air until I found it during a rebuild), the starters I had to replace, rusted stuck quad control handle/shaft, dead gauges, useless on/off switch subject to rain death, batteries... Well you name it. It has been a constant maintenance and repair headache with only limited usefulness time.
If you have a small place and need an actual and dependable work machine this is NOT the one you want. Get a new one you don't have to spend all your time working on.
