ALL valves will leak down.
Cylinders have seals. Valves do not. Its simply a VERY close tolerance metal on metal. But no actual seals.
How fast a valve leaks down ultimately depends on manufacturing tolerances and (cost). And what is acceptable to one may not be acceptable to others.
For me....NO amount of leak down on the side link is acceptable when mowing. I may be mowing for 6 hours straight.....and even at 1/4" per hour leakdown is gonna require adjustment several times during the job....just not as many adjustments as 1.5" per hour. However.....neither is acceptable in my book for mowing.
The toplink however doesnt matter when mowing for me. For starters when the tailwheels of the mower are on the ground....its not under any kind of load to induce movement. And second.....its a floating clevis for the toplink of the mower....so the toplink mount isnt rigid. Its allowed to "float" based on terrain.
To solve the sidelink issue....I simply go back to the factory setup for everything that does NOT require tilt adjustment. And when I want to put the blade on....it takes maybe a minute to throw the sidelink back on. And since when blading....Im constantly adjusting the sidelink and toplink anyway.......slight cylinder creep throughout the day is not noticeable due to constant adjustment anyway.
