Well thanks to hydriv for the instructions

Drop the 1/4" hex plug. Remove the line, orange one in the picture, that crosses the path over the hex plug with 5/8" wrench. Screw the extension line in there. Put line with 5/8 back on. Screw gauge onto extension line. I got the gauge from Northern, zip tied on there

In HIGH range, against a rock, it will put 2500psi. The relief valve goes off. wont spin the tires
In LOW range, against a rock, it will put 2500psi. The relief valve goes off. wont spin the tires

And I drove it down the block a couple times to heat up the oil. The pressure stays the same sadly. The drive force does not. Well, Even when cold it wont spin the tires even with these low tires so its not like its a monster when its first started.

Also, I think I said I didnt hear the relief valve. Well I spoke to soon before. Of course it would be nice to not hear it. I think then itd be a $200 problem instead of an $800 one......ouch

Thanks

spoke too soon. talked to Brian Hildreth and he talked me through the linkage.
Apparently a little bit of play make alot of difference. And too me alot of play is 1/2" but 1/16"/1/8" makes a big difference.
hydriv told me that.

GUESS I SHOULD DO WHAT IM TOLD LOL

thanks all! the community for these tractors is great

THANKS ALL

I was looking at your pics and I think you need to ease up on the caffeine a little LOL! But seriously, I'm glad you got it fixed.
