I love these tractors! My TYM 474 FEL isn't lifting heavy loads as well as it used to, and it can't even lift its wheels off the ground anymore. It worked fine for the past two years, but this spring, it's been struggling. I’m thinking I need to check the PSI; I believe the spec is around 2260 psi. Does anyone know where the adjustment is on the valve for a 474 HST? Is it a shimmed spring or an Allen key adjustment?
You might have a boom lift cylinder by-passing a little. Get a 0 to 3000PSI gauge and a ISO male hydraulic tip and stick it into the rear remote. Your pressure should be above 2,300.00 check at full throttle not with Auto throttle. If pressure is good look into re-building the cylinders. Those trying to lift heavy loads with auto throttle is asking for poor performance. It's best to have your RPM above 2000 when operating under heavy load conditions.
Thank you! I am new to the tractor world and have 50 hrs on my TYM 474 and have owned it about six months. I noticed the other day that the bucket would not curl down using pressure and that I could curl it up just using my hands with the engine off. I googled the problem and this video came right up and sure enough I had one of the hoses loose. It had not fallen out. so thanks again this kept me from having to have the dealer pick it up for a repair. When I was hooking the hose back up I struggled for a couple of seconds getting it in there and heard air being sucked into the cylinder. Is this anything I need to be concerned with or with the air work it's way out?
Hello, i noticed your answering questions... i have a tym lt250 the has a "4 in one bucket" everthing but opening the bucket works it seems to put some pressure on but not much just the pistons move a eighth of a inch. Thinking might be electrical? We have looked at all the fitting they seem fine. Any help would be much appreciated.
my 394 wont turn right will turn left .loader works fine 3 point works fine no leaks .always had a hard time turning one way dont see any videos on this can u help me with this
Steering valve, bent steering cylinder rod, piston seal works in one direction (rare). Remove the right hose from the steering cylinder and install a gauge 0-3000 PSI, Turn the steering wheel all the way to the left and read the pressure. Replace hose and install on the left side and read gauge after turning wheel all the way to the right. if equal then steering valve is ok. raise the front end off the ground with the loader and turn the wheels all the way to the left. Remove left hose from steering cylinder. have someone turn steering wheel to the left. if the hyd oil leaks from fitting on cylinder the piston ring or piston seal is bad.
Simple common problems that can happen to all the brands. Build a shield or protector to eliminate these things. Yes they should already have one in those places but some dont.
Funny not funny.. But this happened to my 574 in the first two hours... I was so annoyed.. I literally looked and pulled on every line to the bucket.. But.. By the time I got to the dealership the fluid collected dirt to see what happened.. The pin to the bucket moved and popped the yellow coneection line JUST ENOUGHto lose pressure but NOT enough to pop off nor pull off by hand...
Tractors are designed to do farm work. Not Brush removal. If the hoses being exposed, use zip ties to re position them. This problem is usually caused by in experienced tractor owners. We work on every color and color does not matter when a machine is not used with in it means.
I have a TYM494 2yrs old with 39hrs on it my problem is it will not start without jumping a wire on starter solenoid I called the dealer they said sound like safety switch but I don’t know where they are the dealer is about 75miles away for dealer to pick up 250.00 one way other then that an explanation tractor
1. Check you brake lights if they do not work you have a blown fuse. Check fuse box under steering wheel. 2. Trace the range and shift levers down and you may find a switch. Dis connect the switch and tie the two of the three wires together. The switch has been discontinued on newer models. 3. Check brake or clutch switch to make sure the button is being pushed in and it has continuity. 4.Make sure the PTO is off. 5.Replace the controller which is a electronic box under the gray steering wheel cowling. 6 Drive your tractor more often. Letting is sit, causes a lot of problems. good luck
You have to look at the specs. Usually TYM out weights a comparable tractor or it has more options that are standard. To me, TYM tractors are a better value than most.
Thanks, this helped me out.
Glad it helped

just cycle the loader and the air will work its way out. put a hose clamp on the coupler sleeves to keep them on if you wish.
my 474 popped off a little higher from the loader attachment pin rotating and hitting the coupler.

Put a hose clamp behind the sleeve .

The exposed lines like that are what's pushing me to other brands.

How do you rate TYM against other brands?
You have to look at the specs. Usually TYM out weights a comparable tractor or it has more options that are standard. To me, TYM tractors are a better value than most.
Mine pop off randomly for no apparent reason lol.
place a hose clamp behind the sleeve.
Or a simple plastic wire tie
Good ideas
