Most modern mowers are of the rotary type. Rotary mower engines are all made to spin at 3,600 revs per minute when not under load. During cutting, the rpm drops to between 2800 and 3300. There is a simple wire-based device for measuring rpm on a running mower, which all mower specialists would own.The other speed linked with your question could be that concerning the velocity of the blade tip as it revolves. As the centre of the blade is spinning at 3600 rpm, an 18 inch blade tip will travel through the air at one speed a 21 inch at a faster speed and so on. Rotary mower blade bars are made up to a max of 24 inches.
Just a standard 20/30 weight motor oil.
A rotary pump can go to about 100 gph. Some can reach 120 gph.
Rotary Broaching is a method of producing both internal and external forms fast and accurately on the end of a workpiece. Rotary broaching makes it possible to very accurate forms within 0.0005 inches within seconds. With rotary broaching not only can you produce standard shapes such as hexagons and squares but also shapes such as Double Hex Rotary Broaches, 6-Lobe Rotary Broaches, Serration Rotary Broaches, J500 Rotary Broaches, Spline Rotary Broaches, Involute Rotary Broaches, Torx Rotary Broaches, Double D Rotary Broaches and any other Special Design Required. Rotary broaches can be made to just about any size, English or Metric. Some of the material that can be rotary broached is brass, aluminum and steel and can go as much as 2 inches deep.
It depends on the mower, but some go 2 miles an hour.
