Toolcat drive issue

[J_J]

At slow speeds in Work Mode with less than max. engine rpm (~1900) I can heard the brakes squealing as I'm moving around even at several mph with the bucket on so I guess there's not enough residual pressure to completely release the brakes. Just sounds weird like I'm dragging the brakes. Makes me think I'm wearing them out fast.

The mechanic/Service Manager said it takes about 300-400 psi to release the brakes but I think was a guess based on some experience. I've never actually used my brake pedal to stop the Toolcat, only to keep it from moving again when stopped on a steep hill. It will start to move once stopped on a steep slope.

I'm not sure what actually happens when the brake pedal is pushed.

Does your brakes hold on a hill with the engine off? Do you have an emergency brake, if so, how does that work. A good tight hydraulic motor will stay in place is no pressure is applied, but if on a hill, the weight of the machine might be able to roll those motors if there is any leakage from wear. The manufactures will state a holding force in ft lbs for their particular hydraulic motor with brakes. My Power-Trac is all hydraulic, and the only brakes are a cogged disk with a bolt that engages the cogged disk. that is used as a parking brake. If the PT dies on a hill, I will be in big trouble if I don't think to pull the lever to engage the parking brakes, and if it is rolling to fast to engage , forget it, I am bailing out.

Just Bought A Brand New Toolcat 5610 And I love it! I can't believe the snowblower attachment nothing like anything I have every owned!

The parking brake works great, engine on or off. I don't know what it does differently than the brake pedal or the motor brakes. This thing stops very well. I'm just starting to get used to letting off the go pedal slowly so that it doesn't stop so fast.

Glad I found you guys.

My 2005 Toolcat 5600 model B has the rear wheel lock up problem and I've determined that it is temperature sensitive. The colder it is - the longer it takes to get it working.

I've found that the blowing 100,000 btu heat on the rear end for about 10 minutes will cure the lock up and it'll continue to work if I keep moving. If I let it sit and high idle for 10 minutes or so, the rear end will lock up again. This happens with an temp or 0-10 degrees F.

The thing will not move until it throws the code 50-14 and then it will move.

The service tech cleaned my battery terminals, said I might need a new battery. I think my battery is ok and my load tester thinks my battery is ok.


I'll find out tomorrow if he re-flashed my computer to ignore the rear speed sensor. This seems like a questionable fix but I'm not a mechanic.

If anybody has any new ideas, please post. And, thank you for starting this thread.

Fixed my problem. Traded it. Life is too short and I'm circling the drain as it is.

I recently received a message (on another site) from a gentleman that had the drive motor issue in his TC. The motors were replaced and after approximately 200 hours the drive motors are failing again.

Anyone heard of this happening twice...?

Maybe left over debris in the system caused a second failure?
My brother works for the state. They had 2 TC's fail from drive motors. They were on of the older series. Way out of warranty but Bobcat fixed them at no cost.

I have a 2010 Toolcat on the yard now that acts that way. When I drive it, it absolutely feels like the wet disc brakes are on. When moving really slow, it sounds like a wet disc brake backhoe does when you are driving through the brakes in low gear. It is not really a squeal as much as a howl. The only thing that touching the brake pedal seems to add is that it will disengage the drive allowing the brakes to grab an immediate stop. This is my first Toolcat to own....Is this normal? I know that in addition to the wet disc brakes that the brake pedal actuate, that the hydraulic drive motors also have a "parking brake" that pressure is required to disengage. It seems like one of the two is not getting adequate pressure to disengage, but that it is disengaged enough for the drive motor to power though it. I have not driven anymore than a total of 400-500 yards for fear of damaging something.

It sounds like my machine is behaving like yours did, and I know that this thread is older, just wanted to know if you had any revelations on the subject. Thanks for the comments!

Mine stopped doing this on it's own after a while. I just kept using it and it went away.

When I step on the brake pedal (which isn't very often) it's a very hard pedal, almost no feel in it at all. Feels more mechanical than hydraulic.

Sorry I can't be of more help.

I never press my brake pedal. Just let off the foot pedal and it stops. Sometimes on a hill I'll use the P park mode.

Anyway, I have a drive issue with work mode - it stopped working any clues. I did read above about software update. I've had mine for 14 years and no update, is that a dealer only procedure?

I did get an idea regarding work mode, going to stomp on the brake and maybe that will reset it.
