Re: hydraulics not working
You need to figure out how the hydraulic system on your tractor operates before diagnosing repairs.
There are several different methods of operating and controlling the 154's hydraulic system. It all depends on how your particular system is equipped and works.
As Stan suggests, obtain the manuals for the tractor.

Describe what you mean by "hydraulic lift not operational". The cylinders are "one way", no down pressure so they will not move until sufficient weight/force is applied to the rockshaft to make them move. As Eugene suggested, figure out how the system works first.

Re: hydraulics not working
I wouldn't drain the hydraulic system or change the filter until I knew how the hydraulic system for your tractor operates and diagnosed the problem(s). Depending on how your 154 hydraulic system is configured, it could take 7 and 2/3 quarts of hydraulic oil per fill.Selba5 wrote:just bought a 154. hydraulic lift is not operational ( deck lift - no 3 point lift) .my plan is to drain the hydraulic system and replace the filter first. any suggestion so far as a thorough draining/flushing of the system?
We are talking many dollars that won't solve your problem.

Re: hydraulics not working
Thanks guys. Actually the 154 doesn't take that much fluid - 7 quarts. so it's not an expensive proposition. no doubt needs to be done anyway from the appearance of the filter. the problem is the deck will not raise - I understand that it is a "one way" system. problem now is that I can't find a drain plug. find the filler and two plugs to check the final drive but don't find a drain. owners manual has an arrow pointing (generally) to an area but I see no plug there . surely one wouldn't have to remove the suction line to drain it. find nothing on the internet that is helpful.

Re: hydraulics not working
Update: never did find the drain plug. used my vacuum to remove the fluid. put in New hydraulic fluid and new filter, deck lift works like a charm.
