B2620 HST question ?

[BrierPatch]

I am currious if anyone else has noticed that thier 2620 has a tendency to roll/creep downhill more than other HST's. I have noticed that I have to use the parking brake an awful lot even on a slight slope. It doesn't creep or roll on flat ground or when I stop. It just creeps/rolls down hill forward or backward and doesn't matter which direction I was travelling. I say creeps/rolls, it is what I would call faster than creeping, but slower than free rolling. It's not a big problem, I just don't want it to be a problem down the road. My dealer tried to tell me that Kubota designed in a small amout of bypass so a dead tractor could be moved. This explaination doesn't make sense to me. So I am wondering if this is normal to these tractors or mine is not right. None of my other hydrostats seem to move down hill like this one, and the newest one of my other tractors is 23yrs old.

I am new to this message board, but I have found a lot of usefull info and alot of you guys know what you are talking about.

Thanks,

Both my BX2200 and B7610 would roll down even a somewhat slight incline while the engine was running and foot off the hdyro pedal. Just get used to using the break or dropping an implement. This is a good habit to get into anyway.

Enjoy the new tractor.

Thanks for the reply and the info. I am glad to hear that my tractor is not the only one that does this. I don't consider it a problem if I am just stopping on a hill, and I drop implements when I am getting off the tractor. The rolling will take some getting use to when doing what I call precise loader or grader work. I can see it especially taking some getting use to trying to line up a phd to hit a mark. I'll have to learn to be quick on the pedals. The first time I noticed it was when I pulled up to a ravine to dump some dirt and I let off the pedal and the tractor started down the ravine. I jumped on the break and stopped, but I had to let off the break again to hit the reverse pedal. Nothing serious, just caught me off gaurd. As mentioned before I am used to hydrostats staying put when you stop. I don't have many flat spots on my land.

Thanks

This kind of worries me a little. I'm taking delivery of my B2620 this weekend that will be used primarily for brush clearing steep slopes, as referenced in this thread...http://www.tractorbynet.com/forums/buying-pricing-comparisons/115967-help-selecting-tractor-steep-brush.html

I really hope I chose the right tractor. This is the first I've heard of a creeping/rolling issue.

righty ho 1st things last: the hydro's will creep they have to. it is just a little bypass inside the hydro units. they are only a metal on metal affair. if you made them tight enough that they didn't creep they also wouldn't work because it would be locked up. the only time to worry is if they loose drive. push something big and make sure it wheel spins and doesn't develop a growling noise. it will whine a lot. more load = more whine.
as for the bs about moving the machine, they can be. just stick them in neutral. the dumb a**e was trying to fob you off. idiots, they think people will believe anything.

G-force,

Don't get too nervous. It is not like it is free wheeling down hills. It has resistance, it is just a slow roll, that I am not used to in my hydro's. Every tractor I own (5) is a hydro and the oldest is 40 some years old. I checked out your pictures and you do have some steep slopes. I also know pictures never do them justice. I really haven't found anyone else mention this issue, so it could just be me expecting my new tractor to be absolutly perfect. I will say, that I absolutly love my new B2620. It starts so easy, it runs so smooth, it has plenty of power, the backhoe digs great. I would really like to know when you get yours if you think it is not staying put on hills as much as you would expect for a hydro.

Ozzie, I agree, I believe my dealer was trying to blow me off. Really dissapointing. He is even a distant relative. (Step Mom's Cousin). I do have an idea (I dare not say understanding) of variable displacement pumps and hydraulic motors and appreciate the feedback and support.

My L3940 does the same thing when the engine is running. Like the others said, drop the FEL and/or implement and/or use the parking break. That's what I do

My 2620 is the same. If I stop on an incline and want to stay put, I have to use the brake. It doesn't feel out of line with any of the other hydro units I've operated though (I was a delivery driver for a mower shop for a few years, so that's quite a few HSTs). Your tractor is relatively heavy and has big tires (leverage on the hydro), so it'll want to roll pretty easily. Don't sweat it. Perfectly normal.

Your dealer's explanation on the other hand...

If you get into some of the higher end tractors, they have 'hill-holding' features which will electronically offset pump/motor leakages to hold the tractor wherever you stop.

I also like the idea of some manufacturers that have auto-brakes when you are in neutral and come off the seat. When doing a lot of on-off cycles on the tractor seat, it would be faster than setting and releasing the parking brake...

I have the B620 and love it. I previously had the BX2200.

My question is this: Why can't we have a brake pedal on the left?

With the hydro on the right foot you have to dance a quick dance to brake.

This is not just the B620. Seems most of them are this way.

I about put the machine in the creek when my foot slipped off the brake and hit the Hydro pedal while emptying the FEL.

The old tractors had both single wheel brakes on the right and single pedal brake on the left.

Think about it.. Gas on the right and brake on the left.

They could even delete a few safety decals by doing this.. Well maybe.
