It shows 1555 hours but meter is broke, the owner had it for the last 20 years plus.

No rust.

There is little wear on draw bar and hydraulic levers are very tight next to my 7050 with 4500 hrs. He had 80 acres and appeared to be a hobby farmer.

The cab is a mess no broken glass, knobs missing, cover for instrument lights missing, some wires are spliced and exposed, motor oil very dirty, motor and transmission complete oiley dirt, to the point it's impossible to see wear oil leaks are.

Tranmission oil 3 inches over full mark?

No front weights.

Engine starts hard and smokes alot I mean alot of black smoke sounds like it is missing also.

Tires like new, dual are 40%.

My question:

1) Is the power shift reliable?

2) If there is a trans problem what is the difficulty in repairing.

3) What is a tractor like this worth?

 

Any advise would be great.

 

As far as the trans, I agree, the P/S trans is very durable.  They can be costly to repair, it depends if you are just into it for gaskets, seals, friction discs, and nuts, or are you into it with hard parts as well.  Hard parts are starting to get harder to find, and therefor more costly.  It's not an easy task to rebuild the trans, but it is doable, special tools aren't extreme, and you can make some of them easy enough.

 

I don't know about cost in your neck of the woods, but I would say the new tires, add around $1200.00 in value, depending on size, (unless they were put on yesterday, they won't add the full new tire price to the value) the engine issues subtract maybe $2000.00, since it at least runs.  I would say that a good running field ready 7020 should bring around 7-10K.  In the Nebraska area, a few auctions lately the 7000 series have really fallen off in price.  I think this is due to the recent disaster of AGCO, and worry about parts availability.  So you be the judge, sorry it's just too hard to guess with your money. :-)
