What RPM should I run my tractor at?

As far as running under load…as others wrote, you won’t hurt the engine running at a higher RPM, but you can hurt an engine by too low an RPM (lugging). I never run mine below 1500 RPM and more if necessary. There’s only two times I reduce RPM down to a low idle… when engaging the PTO and when disengaging the PTO.

The correct engine speed, as revolutions per minute (rpm), will be the best compromise considering economy of operation, emissions, power needed (or speed needed, especially when running PTO-powered implements such as hay balers) and longevity of the engine.

What is live power on a tractor?

Live (two-stage clutch)

A live PTO works with the use of a two-stage clutch. Pressing the clutch half-way will disengage the transmission while pressing it fully will disengage the transmission and the PTO. This allows the operator to slow down or change gears while the PTO is still operating.

1000-rpm PTO, for such applications as grain carts, rotavators, and silage choppers. Use the 35-mm (1-3/8-in.) 1000-rpm PTO shaft on implements requiring less than 150 PTO hp, such as manure spreaders and rotary cutters.

How many splines are on a 1000 rpm PTO?

A 1000 rpm PTO shaft may have 20 or 21 splines or teeth. The faster the PTO speed, the more teeth that are used to make the PTO connection between the tractor and the implement. PTO Sizes: PTO stub shaft diameter for a 540 rpm shaft is 1 3/8 inch. The 1000 rpm stub shaft with 21 splines or teeth is 1 3/8 inch.
