Interesting discovery

[Bri-Guy-GA]

I took the MMM off my BX1880 this weekend for cleaning and discovered a shield on the bottom protecting the fan. Fuel filters and lines were still exposed, but at least the did add some protection for the fan.

That shield has been on the BX since '13 - The BX25D series has them and I am sure the rest of the BX line got them at that time - I had to take mine off and put it back on a couple of times. Getting some of those bolts back in line was a pita.

I left it off for good simply because the BXpanded under armor covers the area better and it takes me longer to get to the ground and back up than to remove the under armor.

I replaced all the fuel lines and rerouted for a new filter system thus having to remove all of that.

I can confirm that my 2013 BX1860 has one. My neighbor's BX2350 does not have one. His HST fan has been broken for about 5 years that I know of. I was doing an oil change for him when I discovered that his fan had all of the blades broken off. The interesting thing is that he has been operating the tractor with no problems for at least the past 5 years without that fan.

If you don't subject your tractor to anything more than mowing on gently sloped land, it probably won't have a problem without the fan. I've had my B-series (which has a conventional hydraulic cooler in front of the radiator and engine fan) working so hard the hydraulic HST fluid was puking out the back fill / vent.

My 2019 BX23s has the guard. YUP, PITA to get them bolts back on unless you've BTDT B4 ....
I wonder how messy it'd be to NOT remove it when changing that filter though....

I can answer that! It is not too messy if you first drain all of the fluid out before taking the filter off. I drive the tractor up on ramps before I drain the fluid. That gets almost all of the fluid out so there is almost none left to drain out, except for a little bit in the filter. I also make sure that the loader pistons are compressed to make sure all that fluid is in the reservoir.

First hydraulic oil change I did on my BX...... in a gravel driveway, pulled the MMM off .... and got new filter ready, broke seal on old filter - spun old off and the new one on, lost a little bit of fluid, maybe a 1/2 cup.
Here is what I learned, gravel sux and being older sux - lucky I had enough ump to get 'er done!

Last time I did it ...... drained hydraulic oil and took my ever loving time to let it drip!!!

That could be, but I would never take the chance of running my BX if I destroyed the fan. Too risky...

Troverman, may be time to make sure your hydraulic cooler heat exchanger is clear of debris.

With a BX it makes no difference whether the hydraulic oil is drained or not, you can only lose a 1/2 cup or so as the filter is pressure fed and exits thru a regulator valve.
