Yep homemade. Not one of our 3pt conversions, nor a factory. The toolbox has been moved to the place it belongs on a WC. Has curved shifter, so is either a WD45, or a late WD. Look at the right side of the motor, if there's a big plate, its a WD motor.
Those lift arms look awfull light to do much real work compared to what the WD is capable of.
Not sure of NY, but here a wide front WD would be worth about 1500.
