"It's virtually foolproof and more dependable than conventional screw-on or snap-on mechanical stops," says Lyal Ismond, marketer of the new Hydra Control Kit. It fits most hydraulic cylinders from 2 to 5 in. in dia. with an 8 to 16-in. stroke. Optional push rods are available for shorter or longer cylinders.

It's easily installed, easily adjusted and provides full range control, according to Ismond. It replaces mechanical stops and relieves pressure on the tractor spool.
