Other models not pictured- 3016PS, 4016PS, 3021PS, 4021PS, 4023PS, 4221PS, 4223PS
INGERSOLL 3018 POWER STEERING
The 3018 Power steering is the same basic machine as the 3018, but with power steering, along with the power steering comes a bigger hydraulic pump as well to feed the power steering system. This was the popular model in the 3000 low-profile series. All power steering models were Onan powered as to handle the bigger pumps used and the load placed on the engine. ( The last generation 4021-23 AND 4221-23 were offered in PS and used Big Block Vanguards 21 & 23 horsepower.)
INGERSOLL 4018 POWER STEERING
The 4018 power steering was a popular option for those that wanted the big wheel models and power steering but did not want to spend what a 4020 PS cost. Again the same machine as a 4018 but with PS and the bigger hydraulic pump.
INGERSOLL 4020 PS
The Ingersoll 4020 PS was the Flagship model for many years. It was the big dog, we find many were outfitted with the hydraulic PTO option and the 3-point hitch option. Those that bought the 4020 PS wanted all the bells and whistles and the cost seemed not to be a concern for many 4020 PS buyers. Interesting to note all 4020 PS were Onan powered as were all 4020 models. But When the later version generation GT black frame models were released they all had been switched to Vanguards for a while by then, but the Black frame 4020 PS GT was still powered by the Onan P220. The Power red 4020 was very popular and we see many. But the Black frame GT is not very common. We are lucky enough to own a few. The 4020 PS model is our favorite 4000 series model.
