Taz.........YES, you got a deal. Can't tell by the pics but does the motor have one belt or two?.........Matters, for if one belt it is probably a 4 speed by changing the belt/pulley position or if 2 belts it is a 2 speed. Not really relevant for me as I run mine on the slowest pulley setting...........
For me, I would change out the tires as those on it wont get much traction in the garden. Also, it needs a depth adjustment bar there at the rear like the little one has. Yes, it matters as you set the depth that you till with it..........
Do a search for manuals and parts here on the forum.........There was LOTS of stuff posted last year about maintenance of these things and you should be able to find most all of the printed stuff with a good search or two.
DO CHANGE the fluids..........Pay particular to the levels in the drive mechanisms.........
Welcome aboard Bud.....Ya did good.........God bless.......Dennis
