Is hydraulic pressure deliberately set "low" from the factory or dealer?

Title says it all.

Found the pressure on my B21 to be about 1800 psi and adjusted it to 2000 psi which is the "factory spec".

From what I've read it is very common for machines to be found 200-300 psi lower than factory and was wondering why?

Less chance of things breaking, less chance of warranty claims....

When I had my old BX in for service of the hydraulic system the service department wouldn't raise the pressure from the original factory setting of about 1400 PSI. I was going to do it myself but I sold the tractor when I bought a BX23S. That one the original setting is 1750 plus or minus. I have the shims and the gauge, just waiting for cooler weather to do the hydraulic fluid change, add the wheel spacers, and the 200 hour maintenance servicing.

The vagaries of manufacture and assembly. Pressure is probably calculated based on the specifications for the spring and poppet size then simply assembled without any additional calibration.

My L3901 is right on the money. Who knows what your 20 year old machine was when it was new.
