Somewhat Scary Experience

[ptrotter]

Yesterday I was mowing the lawn with my B7800 and MMM and had a scary experience. I had just turned down a slight hill and removed my foot from the forward HST pedal and instead of stopping, the tractor kept on rolling down hill, maybe even accelerting a little and brakes had less effect than I would have expected. This has never happened before, usually the tractor slows and stops immediately after lifting my foot off the pedal. The only difference this time is that I was in 2WD and I usually use 4WD. I put it back into 4WD and it was back to normal. The hill was not very steep and quite short so it wasn't an issue, just a small scare when the tractor didn't react as usual. Has anyone seen this before, or is it normal in 2WD?

This is relatively normal, especially if you have the loader attached and/or the grass is wet. There isn't enough weight on the rear tires to slow you down.

ptrotter,
As kevin said it is normal. I have steep hills to mow and today was out on a flat spot so put my BX in 2WD and forgot to go back to 4WD when I was back on the hill and luckily I was on the downside when I went down and the exact same thing happened to me. I always mow in 4WD because of the hills.
Take care TPS

Thanks for the responses, I feel much better now. I rarely take the tractor out of 4wd so I had very little experience in 2WD.

My B7800 would do this so I always kept it in 4WD except when going up the road or for that matter down the road. If you ever hit wet grass going down hill you will always remember to never do that again.

So, theoretically speaking, is there any good reason to ever put it in 2WD? I'll be taking delivery soon of my first-ever tractor and was thinking I'd likely always leave it in 4WD.

That is an excellent question. For many tractor owners, they should
never take it out of 4WD. If you drive on pavement, however, you will
wear out your front tires very quickly driving in 4WD.

I once had a scary moment, when I was a newbie, having put my
tractor in 2WD (I have lots of pavement as well as lots of unpaved hilly
land) and forgetting it was in 2WD. I never forget now!

Why I keep mine in 4x4.

You'll scuff up the grass a bit more turning in 4WD than you would in 2WD. Probably a little more fuel consumption in 4WD. I live in Illinois where we haven't seen a hill for years, so I don't use 4WD very much unless I'm using the bucket and need the traction.

I've had the opposite experience...I've found the rear wheels of my Kubota do more damage on turns if I am in 2WD.

I've had the same experience as the thread starter and now always operate in 4WD unless traveling on a road
