Tractor has been sitting for 1 year. Owner said powershift worked fine. But when cold, clutch does not work, but after it warms up say in 45 minutes at 35 degrees farenheight outside it starts to work just fine. Could this be a the clutch cable being dry and just needing to warm up to fully engage. To get the tractor to move when cold I just hit into 2nd range on powershift and it takes off. I haven"t had time to look at yet, but could it be old dry clutch cable?
 
On dads 1370 you have to pull up on the cluth pedal when its cold out, don't know if this is your problem. His pedal is sticky and it doesnt fully release unless you pull up on it with your foot.
 
This seems like the same problem. Also when pushed in, the rpm's do not change but after warm no problem again.
 
Clutch pedal has linkage, not cable. Pull the panel off the floor, check the linkage to see if it is all tight, and watch the inching spool to see if it moves all the way in when the clutch pedal is up. On my 870 the goofy linkage that bolts to the side of the bell housing was so warn that it would bind and the inching spool would not move all the way in. Good Luck DK
 
Get a 600 lb gage and put it in the C2 port on the powershift valve top cover and watch the gage while it is not moving, the 4 speed need not be in any gear as the ps is a seperate unit. Shift it into 3rd and watch the pressure, then reverse, as these are the three positions where C2 is used. As D stated the clutch spool must go clear into the body and bottom. If there is a top stop bolt in the pedal remove it and throw it in the spare bolt bin, then adjust the lower one till it just touches the firewall as the spool stops in the out direction. There is no cable on a 870 so you can forget that as he also stated. Get back with pressures and we will se if we can help. mEl
