Used to own a 1440 1979 model, The 1981 or newer would be a better machine because of the electric hydraulic system. We now run a 1640. Do wish that it had the heavier axle of the 1460 or 1660. With the factory axle you cannot put a hopper top on without causing stress to the axle.I would guess the value to be in the $5,000 range. Bought our 1440 back in 1996 for $11,000 with about 3500 hours.
