I just purchased a 420s with 3 point. The 3 point goes up ok but only goes down when I stand on the cross bar or have a heavy attachment. Should the spring attached to the left side pull the 2 point down or am I crazy.

Thanks Bill

Bill, is it is a single touch-o-matic? [more common on a standard]. Or is it a dual touch-o-matic? let us know?
~The spring [single spring on a single T-O-M, two springs on a dual T-O-M] should return the lift arms to the lowered position...Does it lower by itself if you turn the engine off? If so you have other problems such as an internal valve leaking, mis-adjusted, or a control linkage problem. If it still stays up, the piston might be sticking in the cylinder, or the rockshaft might be hanging up in it's bore, or even the spring could be weak. ~I have seen the lift arms not lower by themselves after a new piston ring is installed, especially if the cylinder was honed.
~If it works good otherwise, you might want to use it for a while to see if it frees up some.
~If it is a dual system, make sure you have the crossover valves & control levers set for the use intended..... ..... ...

Actually, I think there should be a spring on both sides. Also, make sure the inside control lever is in the up position. And the lever under the left side of the seat flipped forward.

I think (and I could be wrong)that it only has 1 spring
