I have a 1962 IH 404 that I'm having some issues with. I've noticed that when the tractor first starts and until it runs for about 30 minutes or so, the pto shaft continues to spin even though it is disengaged. If I grab the pto shaft, it's not engaged and will stop spinning. If I engage the pto, it works correctly. Now, after the tractor runs for awhile and gets warm, this problem goes away. I'm wondering if this is an adjustment issue and if so, what needs to be adjusted?
Since this tractor doesn't have live pto, I feel like this is connected to other problem I have which is that until the tractor gets hot after working for awhile, it's always grinding gears. I mean I can depress the clutch and wait 10 seconds for spin down and it will still grind going into any gear from a dead stop. If I feather the shift lever towards the gear I want, I can feel the gears still turning and then start to slow down with the pressure I'm applying from the shifter. If the tractor gets good and hot, this goes away and I can shift without issue. Since I have noticed that both the gear grinding and pto issues seem to go away when the tractor gets warm, I'm trying to figure out if there's a clutch issue or what.
I just purchased this tractor and am new to tractor mechanics so I need some advice on what to adjust.
