It's A Beast!
Model Year: 1992
I bought this G1900S (4-wheel steer model) with 54-inch deck new in 1992 when I bought a 3-acre house. It mows great and the 4-wheel steering is wonderful around trees. I'll gear the review towards people looking to buy a used one now. This thing is built like a tank. We used it to clear about 1 acre that was overgrown with thick bushes. I seriously abused the tractor and it took the punishment without complaint. I nicknamed it "Agent Orange - Military strength defoliant." It has a nice big 5 gallon tank for the diesel fuel. The hydrostatic drive is simple with one foot pedal and the hydrolic lift on the deck makes raising and lowering it easy. Maintenance is pretty simple, although you need a funnel to drain the oil unless you remove the mower. Grease it, change the oil and you're good to go. The 4-wheel steering makes this almost as easy to mow as a zero-turn. I now have a 4-acre property that takes about 2 hrs to mow. If I trimmed the trees it would probably take 15-20 minutes less. The mower is FAST and chews through grass like nothing. One complaint about the 54-inch mower is that the rear wheels don't pivot, so when going around trees with 4 wheel steer, they drag and leave rings after a few mowings. Also, the front of the mower is held up via a nearly-horizontal linkage. After bashing the mower a few times, that loosened up so the front of the mower now rides on the anti-scalping wheels while mowing. I go through a set of those anti-scalping wheels every couple of years. If you're looking at one of these, get the 60-inch deck if possible.
Pros: Build quality, fast, built like a tank
Cons: Front mower linkage
