I bought my JD 2030 used without a loader. I looked three years for a loader. Then it was missing mounting brackets, (not the main mounts) hardware and hydraulic fittings to attach. I was lucky it had the valve, joystick and cables. I had to buy the mounting bracket for the joystick too.
I bought all the parts from the JD dealer at about 5x what I had guessed when I bought the loader. It can be done, but it takes time & $$$, and labor to install. You also have to make sure the valve is compatible with your hydraulics, open center verses closed center. JD made both, some even in the same model number, mid year
change.
I second buying with a loader, much easier.
Sounds like my suspicions were correct. I keep seeing tractors without loaders that I could buy and put a loader on, or having people tell me about a tractor and then say "you can find a loader for it later"
Without too much research, I figured that it would probably:
1. take about 6 months to find a loader, maybe more
2. it would probably cost $3,000 to $5,000
3. I would have to drive a minimum of 12 hours round trip to go get it
4. It would almost certainly not fit right away, and I'd have to buy parts for it as well as fab things up
5. It would take at least a week to get the loader fitted up properly
6. There's no guarantee it would actually work right by the time it was mounted.
I've been really trying to get the loader and tractor together to avoid all the hassle. Even buying a new loader from Westendorf or Woods etc, I'm still going to have to figure out pumps etc.
