I have a grinding noise when first letting out the clutch. When I press in the clutch to switch to Neutral the grinding is worse till it is placed in Neutral position then I have to wait to place in a higher or lover gear.

So is it the clutch or gearbox?

Thanks for your input
 
It sounds (with way less information than needed, like what tractor it is , how old, and if it makes the noise when letting the clutch out in Neutral. If it stops when in gear clutch down, or when underway clutch out.)
Like a frozen or near terminal throwout bearing. Jim
 
Sorry Jim, it is a 1951 Farmall Super A.

So if I am sitting in Neutral press the clutch down place in 1st let out there is a grinding. But when I place a foot on clutch in down position I have to place in Neutral & wait till I can place in a high or lower gear.
 
If you are new th this tractor, you are describing normal vintage tractor operation.
The gears in a car transmission are controlled with little braking devices that match up speeds of the sliders used to shift.
In your transmission the gears move on shafts, sliding into mesh with other gears. They are free to smash into each other when doing so if they are not stopped, or matched in speed.
THe shafts and gears are heavy. They spin redilly and continue to spin when the clutch is pushed in. The oil in the trans slows down the gears over a period of 5 to 10 seconds or longer when the clutch is pushed down. If the gear lever is moved into gear while they are moving it will grind substantially.
Letting it stop prior to moving the lever is normal operating procedure. Moving it too soon reduces the life of the gears. Jim
 
So you're hearing the grinding when you let the clutch out in gear, right? All gears, or just one? The second symptom you're describing sounds normal to me, like maybe Hytran was added to the trans, or your oil level is low in the trans.
 
I agree with Jim, more information is needed to determine causal factor(s) and even with that, then it might not be anything more than what is considered "normal". I still do NOT get the sense if the noise is actually gear clash (when first attempting to move the shift lever into a gear selection due to longer gear spin times with the clutch depressed) or a noise that occurs after the gears are meshed and the operator is starting to engage (let up on) the clutch. If the former, it could be longer spin times due to trans fluid friction (and contrary to what I know with regard to viscosity affecting that, having hy-tran in the trans would reduce spin times vs typical 90 wt gear oil). If that is the issue, it would also be worse when the tractor is cold rather than hot. If the latter causal factor, then as Jim says, it could be a throw out bearing noise; could also be P/Plate to clutch disc noise {e.g. chatter or the like}. Way too many causal factors unless we get a more exact description of the conditions under which the noise occurs. Sorry to be so verbose - it"s the engineer in me.
 
Realized I typed wrong with regard to viscosity of fluid affecting spin times. Spin times WOULD be shorter with hy-tran fluid than with 90 wt oil as greater viscosity fluid increases spin times.
 
Spin times are longer with low viscosity (SAE 10)Hytran; high viscosity shortens spin times. The longer spin times are very obvious with TA equipped tractors which must use Hytran. Hot oil, particulary ones like Hytran also lengthens spin time, unless you have a multi-viscosity version. I have both TA and non-TA tractors.
