Hi Dave,
You might try the Yahoo Gravely Group, or just hang out and someone will probably come and answer here.
Oh, you might wanna try oldgravelys.net for many many PDf manuals as well.

Gravely PTO speeds are about 900 RPM.
Richard Tx Thanks for your reply to my Gravely RPM. question, Would your answer of 900 RPM. be the normal operating speed? My gear box ratio seems to be aprox. 10-1 That would be a little less than 100 RPM. for the augar speed, does this sound correct to you?
thanks Dave

The PTO speed of 900 RPM is at engine rated RPM. The old L models which had a 2400 RPM Gravely engine had different gearing than the later tractors that had Kohler, Briggs, etc which were rated at 3600 RPM. In any case, the PTO RPM stayed the same.
The blower gearing is what it is, so 10:1 seems fine to me.
Be aware that some snow blowers have a bronze gear in them. As such GL4 lubricant is mandatory. GL5 acts more like cutting oil to yellow metal.
