Hi JDBrian: Thank you for participating in my thread. I agree with what you said> If it was my tractor I would want to know the rated and maximum speeds so I wouldn't overheat it.[/QUOTE] That is part of the reason why I joined this site.... I was hoping that someone would not mind sharing the information so as to help a fellow tractor owner out. So many of the dealers are more intrested in selling new tractors and new implements that older tractors like mine and others are pushed to the back burner, I've even found out that for my tractor, they don't even keep parts on hand anymore, the always have to order them. There are a few on this site who seem to know quite abit or have access to the information that they seem not to mind or even infact they quite enjoy sharing their information that they have with the rest of us:beerchug:. With that being said does somebody out there know what my operating Rpm range is????
[quote name='JDBrian']The HP race between JD
and Kubota has seen them playing with the rpms that they rate their engines at. By rating them at higher rpm's they get a bigger number. The older versions of these small JD
CUT's used lower HP engines that were rated at lower RPM's. With the higher rpms comes different gearing in the trans. to get the rated PTO
speed to match up with engine max. power. It would be the same deal for mower decks running off the front PTO
. The gearing would be designed to use the rated engine HP at the correct blade speed.
So for the Ford in this thread there would be a rpm corresponding to the correct pto
speed to get the rated engine HP to the blades. If you run at a faster than rated speed there is more likely to be overheating issues with high ambient temps. I think that may have been what the dealership was getting at. If it was my tractor I would want to know the rated and maximum speeds so I wouldn't overheat it.[/QUOTE]
