The steering is slipping when it’s in any kind of bind,I’m looking for a diagram on the steering for a murray 14.5hp 42in.deck riding mower.
Attached an image of a murray steering and hope it resembles what you have. Since it s working with no load on the wheels, but fails with a load, check the mounting screws and make sure that they are A. tight and B. That your steering is mounted so that the gears match. If the rack or the gear are loose or to far apart, they may spread under load and this cold cause slipping. Of course, also check the gear sector and the pinion gear for excessive wear.
