Comment: I own a Ford 4600 tractor and am having problems with the hydrualics. With out the slasher on the 3 pl it will go up and down,when I put the slasher on ,it only takes the weight and stops .The tractor also has an aftermarket front end loader fitted and this operates very very slowly as is the 3pl The front end loader lifts to full height and loads the hydrualics up and the reliel valve opens,and the engine also labourers a little.The problem started when the slasher dropped quickly and loaded the hydrualics and sheared the bolts holding the two parts of the internal hydrualics together.This has all been reassembled by a hydrualic mechanic but is not working correctly. Has this happened to anybody before and can any-one help me help my tractor , I am lost without my tractor!!!!!!!!!! Thank you Jeff Paul
