When he was lifting a heavy load on the 3 point linkage there was a loud crack and the load dropped to the ground. Steven suspected a broken lift cylinder and this turned out to be the case. Steven suspects that ther relief valve had stuck in the closed postion, but isn’t exactly certain of what caused the cylinder to break.

This just reminds us of the magnitude of damage that can sometimes occur in powerful hydraulic systems.
