I am in the process of ggetting an Alroh 17BDB up and running properly. The first test run went ok but the mower speed was a lot higher than I thought if should be. I reLly had to move to keep up even with a lower engine speed and tbe clutch just driving.

All the pulleys look original so I assume it is running at the designed speed. Does anyone hVe an idea of what the normal or average speed should be for the drive reel and cutter reels. Once I confirm a normal kind of speed I can check the Alroh ratios and decide on whether to change any of the pulleys.
