HARRY - Technically, yes, nine forward and three reverse, but a "4-Speed" or "5-Spd" or "9-spd" always refers to just forward gears. Then there's the ready-mix cement truck I drove the summer of '76, an old '66 White Mustang I think they called it, 165 HP Cummins, 5 spd main & 4-spd aux. gear box. I had 15 forward gears for hard surface conditions, four forward creeper gears, and four reverses. Your normal Eaton Road-Ranger truck transmissions all had 2 or more reverses, and those with "Splitters" like the 13-spds you had four. Same thing with medium duty trucks w/2-spd axles, hi & lo reverse, but they were called a 4+2 or 5+2.
ANYHOW... Gear Drives Rule... Hydro's drool.
Some day when I retire I'm going to Build the Super Garden tractor IH should have built. Not sure what the engine will be but the rearend & transmission will be from an A or B Farmall, 4-spd forward. Probably use about a 8" x 16" rear tire to slow it down a little and keep the drop boxes on the rear axles. With stock 9X24 rear tires it had 2.3, 3.6, 4.8, & 10 MPH forward gears. Lots of ground clearance that way.
DAVID - SON pulled a "Low-Rider" '64 Impala with my 982 a couple weeks ago up his sloping concrete driveway. I even got to see the black marks from MY expensive Firestone tires! Car was missing a few parts, but all the batteries, pumps, & motors for the hyd lift system was still in tact as well as the engine & tranmission. In fact they used the lift AS a lift to work under the car.
You get those little tractors on good footing and it's amazing what they can pull.
