Yes, it can't hold 3-point in the air. The weight attatched pulls the arms down; some of the weight is transferred to the lever itself. This forces the little lower limit knob to shift. Lost a brushog blade on a stump because it dropped. I'm actually considering chains on a new tractor! At one time the lever would not move at all due to rust. Position control is to hold a couple thousand pounds. My dad uses this tractor mostly to brushhog , but cannot stay turned around backward to continuously watch it. The operator should raise the cutter to the lowest height needed or at the cut height, then raise it over bumps and during tight turns. the stop knob controls the minimum height and the friction of the lever should control the temporary height without the operator continuously holding it.
SILVERB, The tractor is a 3500 hst. It has no clutch or gears. Just high, med and low range. If the 4wd worked, the engine drag would have slowed the tractor.
I have another question for this forum. Has anyone noticed that the draft control must be used to get the arms to move their full range? To raise the post auger out of the ground, the draft control must be pulled to its rear limit. To get it low enough to pick up brushog from the ground, the draft control must be all the way down. You would think the position control lever would do its entire range with the mostly obsolete draft control at zero.
