I've got one of each (of brands you mentioned) plus a few others. Deere 300B, Ford 4000 Industrial and a Case 580CK. Also an IH 3414 and a Pettibone-Multihoe LDA.
The Deere 300B is by far the nicest to operate and drive. Also uses the most proprietary parts, although I've never had any trouble getting any. It is a little "Cadillac" compared to the rest.
The Case 580CK is very rugged but I hate the torque-converter drive, and never liked the foot-
pedal swing on the hoe.
The Ford 4000 Industrial is crude but rugged hoe. Mine has the Sherman over-and-under aux. transmission. If it did NOT have that, I would like it a lot less.
The Pettibone is a big ugly monster but uses more generic truck parts then any of the others. Has a torque converter drive with a power-shift trans, Detroit Diesel 3-53 engine, and air-over-hydraulic truck brakes.
The IH 3414 is basically a beefed up British farm tractor. Very rugged, crude gear-reverser, odd-
ball two-pump hydraulics with a rack-and-pinion hoe swing. Parts are mostly British and not always easy to find in the US.
