I have a 1999 580 super L the problem is track has no drive power enless you lift or tilt front bucket, if you lift or tilt the front bucket the tractor has lots of power. ex. try to drive up a hill on a paved road engine rpm will die down but if you lift front bucket up while driving it instantly goes to top rpm.

lift pull towards you

put the bucket on the ground and the tilt in a neutral position so that there is no load on the cylinder pins
turn off the engine
remove the hoses and cylinder pins
lift out
use plugs to control dirt from getting into the hose ends

the return valve or tilt back control is allowing oil back and not locking the bucket in a set position so that when pressure is applied as in lifting ( moving backwards to smooth out) that oil in the cylinder is not held in check
check bucket controls and valves

I. Hope you know where to greet the trac . OK if you do. Take that grease zero fully out. Now you need to pull on the track X after you lift the front of Te track off of the group d with the bucket lift. AZ you pull sick in the truck grease wi come out that zero hole once you have collapsed this plunger all the way you should be able to slide or pry track off of front gear and follower bearings

The window track should have a bolt at the bottom so the track can be moved away from the window to allow enough room to slip it in between the tracks.Also the door skin can be unbolted to gain access from the outside of the door which may make it easier.

It does have a tilt over safety feature. But if it wasn't plugged in when it tilted, it shouldn't have tripped the switch. However, if it was plugged in, it probably tripped the switch. Check your Owners Manual for how to reset the switch.

76lb/ft on the upper and lower nuts

it may be broken

the middle seats come out easily. There are 2 handles you have to lift up on each of the bucket seats, they are in the front of the seat down by the seat tracks. After you lift them, tilt the seat upward in the front and rotate them backward. Then lift out of the hooks. Each seat is held down by 4 hoks.

The 3rd row seat is not designed to come out xcept by a technician. It does slide forward all the way up to the front seat. It has a sliding seat track.
First, lift the T handle under the seat cushion on the left front side of the seat. This will allow you to lift the seat bottom up all the way to lcok in the full up position.
Then, lift the lever on the same side of the seat and slide the seat forward. It will stop in 4 places.
Rear -Rear
6 inches forward of that.
another two ft to the second row seating position
full frward against the front seats.

Pleae rate as fixya if this helps.

after the idler is pushed all the way back into the frame.try to put some wood blocks under the track to remove all the slack.use the bucket to push as much of the bottom section under the bottom rollers.use a heavy chain and pull up and over the top of the roller.when you get close you can use the drive to walk it the rest of the way.if it still doesnt go you may have to break the track at the master pin. this is usually marked with a small hole drilled in the end of the pin.heat and beat the pin out,break the track.pull track over top rollers and make ends meet on top of the srocket.use a chainfall to pull two halfs together and line them up.drive pin back in and your all set.
