Case 801B

Case-O-Matic drive is a torque converter mounted ahead of the transmission. It has an in internal clutch that can be engaged to stop all slippage from the converter. Low range does not change gear ratios, only unlocks the converter clutch to allow the engine to run at a higher speed and not stall. The tractor movement is always started in low Case which allows the converter to drive like starting out in your car or truck with automatic transmission. The tractor can sit at idle in low Case and not move until the throttle is advanced. The faster the engine runs, the more power is transmitted through the converter, therefore less slippage. The tractor should not be used in low Case for long periods under a heavy load or the oil will get hot. Always idle the engine before changing gears and engage the foot clutch at idle and use the converter to get moving, then shift to direct drive. Inching is done with the clutch engaged and controlling movement with the foot throttle and brake. Works nice and smooth and reduces wear on the clutch and hydraulics. I have often left the tractor in gear and idling while I got off to pick up rocks or adjust the equipment.

Kinda long winded, but the Case-O-Matic is a great system when you understand it and use it as it was designed... Gene
