I strongly disagree with the assertion that you "don't need to run the mower any faster than about 1400RPM". The RPM relates directly to blade tip speed which, in turn, relates to the performance of the blades both in cutting efficiency as well as the lift created that positions the grass for optimal cutting. The mower was designed to run with a 2100RPM input (it's not a "maximum" value..it's a designed speed value where both faster AND slower are non-optimal)...if you aren't doing that you are sacrificing performance from what it is designed to deliver. You may feel that you are saving fuel by doing that, but I think you'll find that the fuel consumed on tractors like this is less linked with RPM as it is with the work you are doing with them (like from a physics point of view). If you are barreling through tall grass at a specific driving speed, the engine will add fuel to maintain that RPM which compensates for the drag being put on it via the blades. Each blade of grass cut will require some set amount of energy, thus fuel, to cut. Spinning the blades slower can actually have an effect of creating more drag because the grass is torn rather than cut cleanly due to suboptimal lift and the effect of velocity on the process of cutting..thus making you less efficient in both fuel and time measures. I mean, it's your tractor and you can "do you"...but you're doing yourself a disservice by hamstringing your equipment in this way (IMHO, of course..). For reference, I also have a 2025R and I mow with it as the primary machine for my lot. Other than that, very informative video and I've enjoyed the several others that I've watched of yours :)
Thanks for the comment, the lower rpm works for me but I wasn’t thinking of 2100 as the optimum speed. It wasn’t about saving fuel it just seemed to be fast enough at 1400. I’m going to try it at 2100 next spring and see how much better the cut is. Appreciate the advice!
@@upnorthguy A lot will depend on the grass you are cutting and your expectations. If you are cutting mostly pasture-type things and expect a cut quality of roughly what a brush-hog will deliver, then going with the lower RPM is probably fine. Where the big difference is seen is when you have a dense residential-type lawn where you are expecting a very uniform cut...and that's where it needs the extra RPM's to perform to design expectations. A good video for the spring might be an A/B test to try it both ways and document the cut quality as well as any differences in fuel consumption and time needed to complete the job.

Another excellent video... I'm gonna buy a 2025R
Great ! It’s an amazing machine. Thanks for the feedback!!

Go full throttle…
You can program the tractor to shut off that backup safety crap.
Thanks for the comment, can you share how to program it??
I also have a 2025 and that drives me crazy. How do you shut that off?
