I have a L4300F with 128 hours on it (mint condition). The dealer here wants to charge me $5300 to put on a LA682 FEL on it. I think this is unreasonable-does anyone out there have an opinion on this?
Sorry, but that would be about the going price for a new loader for your tractor.
Even other manufactures are going to get that much for the loader, bucket, mounts, controls, and install labor to fit your tractor.
I just bought a used, Woods loader that fit my tractor, I installed myself and I got a screaming deal on it at $2500. Loader packages are not cheap, and the higher end units cost more but they are completely worth the extra money!
If you want it cheaper find a used unit, but make sure it includes the mounts and controls or you'll have a real expensive paper weight!
But let me back up a little, I personally think you'll be sadly disappointed in the performance of your 2wd tractor with that big of a loader on it.
You would be better off to sell that tractor and get a 4wd with a loader already installed, they perform much better!
