Tractor Lesson: Hauling & hydro

theboman · Jun 6, 2003

My tractor lesson I learned today.

When trailering a tractor such as a B7500. When you have the tractor loaded put it in low 4 wheel drive and set the parking brake. This locks all the brakes on all 4 wheels. In two wheel drive you only lock the rear tires by setting the parking brake.

The BX mowers that folks burn up the casters (anti scalp rollers) on the decks, it's not so much of a problem with the decks design but the owners are setting these too close to the ground, they should not be rolling along the ground unless there's a high spot the BX has a suspended deck not a floating deck. They replace these often.

One of the guys at the dealership didn't realize the BX don't have a tach. I told him about the tiny tach and this board. He then went on to tell me they tell folks to run the throttle wide open when using the PTO because too low RPMs cause nothing but problems and that tractors are designed to be worked and not lugged. You can't over rev the engines from the factory (unless you've messed with the governor/carb on the machine).

When checking the hydro fluid make sure the FEL is down compelely, the lines on a B7500 can hold several gallons of hydro fluid.

I keep the anti scalp rollers on my BX set a lot higher than the book says and have had no problems with them so far. My yard is mostly just an old pasture that I mow. Definitly not very smooth and if I set them at the recommened level they tend to want to turn all the time.

I thought they would have made the rollers a little more robust though,at least something that you could grease. Dave...

I do the same thing (running the rollers high) and have seen no real difference in cut. I set them for a 3" cut and then set it at 3.5" to mow. I wish they made a ball bearing roller, but I guess cost is an issue there. I took all of them apart and lubed them once after getting into some mud with the deck on, and they are already dry again. I guess I'll pull them apart again......................

Whether the loader is up or down, the lines will always contain fluid, they do not drain out with the loader up. The only difference in volume is that when you have in this example the loader down, that area of the cylinder that is filled with fluid when the loader is up is diminshed some by the hydraulic componets, namely the hydraulic ram. I see no fluid level difference on my tractor with all hydraulics extended or retracted. It might make a difference on yours however. Rat

I agree, Rat. There is a slight difference in the quantity of oil in the cylinders (no difference in the quantity in the lines and hoses), but the difference is not great enough to be of any concern.
