No problem with the description.
The levers are called touch control levers. They are linked with rods to the hydraulic resivoir/power box in front of the operator area. These levers are position controls for two mechanical arms that stick out the left side of the tractor, and one that sticks out the right side. thr right hand arm, and the inside left arm are controlled by the right lever, the left most arm is controlled by the left lever. These arms are designed to controll attachments and equipment for lifting positioning, and directing their actions. They are very powerful and can move several hundred pounds of force. Most of the special tillage tools, mowers, plows, cultivators, and attachments are attached with linkage rods to these arms. The levers are hydraulic controls. The position of the levers controls valves in the system to which they are attached. The valves cause hydraulic fluid (HYTRAN Fluid) to enter hydraulic cylinders within the box. The fluid moves the piston until the arm reaches a specific spot of its travel as set by the location of the lever within its travel. The small sliding stops on the lever quadrant, are for presetting a depth, or setting so the operator can just move the lever against the stop to position an attachment to its correct set depth (as adjusted by operator experience). Levers rearward, arms rearward, levers forward arms forward.
If these levers are (actually) causing the engine to slow and stop, then there is serious problems within the hydraulic box. There may be a very different reason for the tractor quitting. (more likely)
If there is a location of the levers that allow the engine to run, that would be a minor miracle. I think the engine is stopping from fuel restriction caused by junk and flakes of rust in the fuel system. With the fuel shutoff turned on under the tank, remove the drain plug from the carb bowl with a tin can under it to see how fast fuel runs out. It should come out fast enough to fill a one pound coffee can in less than two minutes. If it does not there is restriction in the flow and that is what causes the engine to stop. cleaning the sediment bowl/screen, the stem into the tank above the bowl, the shutoff valve, the line to the carb, the strainer in the fitting where it attaches to the carb, and the needle and seat in the carb are all to be cleaned and checked for full flow. Look in the Search For box with the words to find out what has been written on the topic. Keep talking to us, we be friendly. JimN
If the engine is running correctly, the hydraulic system will cause it to make more noise, but it will not die, even if the hydro unit is trying to lift more than it can. Check out the fuel system, and see if what I have said makes sense.
