Is stalling the tractor an automatic fail on the road test?

It would be in my state.

 

If you're close to stalling in 5th on a turn, you're going way too slow. 100rpm is roughly 1mph in 5th. Close to stalling would be around 500 rpm. 5mph is a fast walk. Step it up.

 

In Ohio, yes. So is lifting both hands and screwing up the break test.

 

Assuming it was a 10 speed, yes 5th is the recommended gear for turns. In a 9 speed, 4th would be the magic gear, and in mine after the 9 was converted to a 13 speed, 5LO was the magic turn gear.

i just recommend applying a little throttle at the apex of the turn. Keep one eye on the left part of the turn, the other eye on the right part of the turn and another eye on the gauges to make sure you're above 1000 rpm. You don't want to lug and shudder like that. Stalling out is indeed a failure.Shows that the driver is not in control of the vehicle.

 

Fail.

You are too wimpy to add power. And you need a eye on at least the Tach, keep it above 1100. Anything below that you need to downshift. Some trucks will lug down but not all.

The situation is made worse by tall fleet generic 10 speed gearing. I don't know how slow you are going, but you don't creep in a turn, add power and get in there. Let's go you will be upshifting as soon you straighten out. That is if you don't hear brakes in stereo or symphonic as several lanes you just cut off screech behind you...

You say shake, I call it bucking. Then it will slam you back and forth causing your foot to slam back and forth on the hammer the first time you slam back, it stalls. cough cough, making you look stupid.

Wait until your stop sign is holding you up on a 8% grade and you have to do a left off it seeing nothing but sky.

 

I always like to be in top gear of low range for turns. I'd rather have the RPM's up higher so I can always back off the throttle and slow down a little if I need to.

 

If I were the examiner I would have failed you. You lugged that engine horribly. Lugging an engine is a sin in my view. In my view lugging also means you are not controlling that vehicle correctly and means you may not be ready to hold a CDL. When you lug it is the same as taking a 10 pound ball peen hammer and pounding on the internal parts of the engine. Actually I think pounding on the engine with a hammer does less damage. If you don't believe me on this ask a diesel mechanic. Some mechanics will actually start (cussing) when you bring up lugging. Inexperienced and/or lazy drivers have a bad habit of both lugging and burning clutches. I can't tell you how many times I have seen a mechanic cuss out a driver after cracking open a diesel engine and seeing damage to an engine caused by lugging and looking at/or replacing a burned clutch. Another thing that pisses off a mechanic is premature brake wear caused by riding the breaks and not using the jake properly. Stay in trucking long and you will see this.

 

^^^ He's right. Some of the drivers we had driving for one of the companies I wrenched for destroyed stuff at an alarming rate. In 12 months I seen 2 clutches lock solid, numerous clutch brake failures, even a couple thrashed transmissions from improper shifting and PTO engagement. Our location only had 25 units....
