HST Creep on Slope

bleedsgreendrivesorange · May 17, 2012

I'm only 14 hours in with my new L4740 cab w backhoe and loader and have noticed the tractor will creep forward or reverse (depending on slope) after I have removed my foot from the hst pedal. I don't think it did this back at 3 hours. Just wondering if this is normal. Thanks

any hst i have run will slowly coast downhill when in neutral and parking brake off. the more slope the faster the coast. still better then a gear shift in neutral, that would free wheel bad. also different hst will coast more or less then others.

Normal operation. They all do it.

My Kioti DK35Se HST rolls on the hills unlike my mahindra 2810 HST. why? who knows .. . Guess thats why they put a parking brake on them . . .John

Well that is good to know. All the tractors I've ever run before this one have been gear jammers.

Well then welcome to the world of Luxury :thumbsup: . . .John

Thanks John! I just love it when I set out too do something and when its done there is still time and energy to do more. I should have bought a tractor 10 years ago.

Mine, when it was new, would hold on a very gentle slope.....now, will very, very slowly creep forward/reverse depending on slope direction and amount. So, my conclusion is that as a tractor breaks in a small amount of creep is typical.

Normal for the HSTs, I have driven.

Just a heads up to all HST owners. Supposedly if you leave the engine off and the brake off the HST will creep forward and pump the oil out of the HST and allow it to then freewheel (or nearly so). I have only read about this but thought it was worth a mention. I get off of my tractor on a hill and I set the brake and leave it running.:thumbsup:

yep, they creep....but only till they reach the bottom of the slope....then they usually stop...

Well, a tree on the way down would do it too:laughing:
Or the side of your garage

yeap...Mine will creep too... even with the brake on and running. I will usually lower the box scraper, set the brake and dig the bucket into the soil when working on my slopes.

I haven't seen a hydrostat tractor or mower that doesn't creep. Once put my ol' JD 425 on a trailer, it was slightly higher in the front than in the back, and forgot to set the park brake before getting off the seat to tie it down. Next thing I knew it was zooming down the ramp of the trailer, thank God no one was standing at the back of the trailer.

If it creeps with the brake on somethings not right.

Mine doesnt move if the brake is set, engine running or not. I love the brakes on this tractor.

can't help but giggle at that one...knowing no one got hurt of course. A good warning and something to keep aware of.

Have to agree there...might need to adjust the parking brake if it does not hold or could it be possible the HST pedal is out of adjustment a little and engaging??

Being in BC I have some wicked slopes and my parking brake will hold the tractor on these hills w bucket in the air, BH attached and ballast in rear tires. I have to give the pedal a good solid push before locking it but the tractor holds, facing uphill or down hill.
