MOWING IN HIGH RANGE

[mlange2009]

Been doing it since day one,someone told me DON'T DO THAT!!!!! will this hurt my bx??? high range 1600-2200 rpm,takes me 3.5 hours to mow

I mow in low range, but I don't think its a problem mowing in high, unless you have a lot of steep hills.

Should be okay if you don't bog engine down push on HST pedal.

You say RPM range is 1600 - 2200. Perhaps it's different with a BX, but I'd check your owners manual to determine what the correct PTO speed is for the mower you are using. For example on my JD the setting for correct PTO speed is approx 2,500 RPM.

depending on how rough the land is and how thick the grass is i uselly mow in high 1 or 2 if its thick im in low 3 or 4. been doing it for years.:thumbsup:

I mow at full throttle on my BX. Don't baby it, its meant to be run wide open for mowing.

Those RPM settings seem far too low according to my experience. I need to push the RPMs up to about 2900 for efficiency in both cooling, HST performance, and PTO speed. hmmmmm.....

It won't hurt to mow in high range, but the RPM for MMM is 2800 or so and rear PTO is 3000 or so. I didn't have a tach on my 2200, so I ran it full out and ten years later my son in law is doing the same.

Exactly. The problem with mowing in high range isn't so much than you are in high range, but the fact that you probably are not running at the correct engine/PTO RPM.

There are several issues at mowing at the incorrect RPM. On the bigger machines (meaning, not my HST lawn mower) I don't know if low RPM is bad for the HST or not. On my mower, I HAVE run wide open to keep the HST from overheating.

On my gear (hydraulic shuttle) tractor, I have to run in low range or my ground speed is WAY WAY too fast. I run in 2nd or 3rd in low range.

The OP is getting good advice here. I think he is operating virtually in reverse of what should be done.

Mowing in high range, but slogging along with low RPM.

Much, much rather see low range, with high RPM. Can you "hurt" your BX by doing what you've been doing? I'd say there's a risk, as you do indeed risk overheating and lugging on the engine and attendant drive train, not to mention a lousy cut from slow spinning blades.
