BlueLite,

I see you emailed me about the manual for the 424.
The email spam filter caught it, and I happened to notice it in the qaurantined items tonight when I was searching for another email someone sent.

It sounds like you have one of the manuals I have, but I think I have 2 more that pertain to that tractor. There is lots of troublehooting information. I am at home tonight, 24 miles from my shop, but will look tomorrow to see just how much info. I have.

It's your tractor, and it's not for me to tell you what to do with it, but I can't understand why you'd want to butcher the 3-point system. These little tractors are somewhat rare, and becoming collectable, and cobbling up the hitch hydraulics would sure knock the heck out of it's value. If I recall from your earlier post, the hitch was working, and quit suddenly. I'm sure it's something quite simple, if you take the time to go through the troubleshooting procedure, and narrow the problem down to the offending component. As I stated before, I have a 424. We have worked the heck out of the three point with a 2 bottom plow and a 6 foot Bush Hog for years, and have never had a lick of trouble with the three point. I also own an old Ford, and the three point on the 424 works like a Swiss watch compared to that tractor.

I gather the fact the valve system is so complicated frustrates you, but it really is a sophisticated system, and probably should be considered advanced for the year of manufacture. With a little patience, it can be made to work again. Email me again if you are interested in the additional info. for this system.

If I recall correctly, the hydraulic filter on this tractor is in the pressure line coming OUT of the pump, which is a bit unusual, but should be good, for the fact it would catch any filings from the system before they get to the 3-point hitch valve. The fact that the filter is rather unusual, and probably specific to this series of tractors explains it's high price.

Good luck, however you decide to procede.
