856 Brake question

[FLtractor 174]

Evening,

 

Wanting to better understand my tractor overall.. can someone explain to me what kind of brake is specifically used on the 856. Does it ever need to Be serviced or replaced maintained ect similar to a car with a rotor disc pad ect? Have been told that these tractors can tow much more than they can safely stop with the brakes such as the 856 has. Is there a specific name for the clutch brake combo … since it allows no on the fly shifting.. have to be completely stopped before shifting to best protect prolong the transmission gears.

All the garden tractors made by wheel horse use a simple band and drum. They can be adjusted, but the only serviceable portion is the band itself. It should be kept clean and properly adjusted. 

 

And the clutch/ brake combination on some older machines is not the reason you can't shift on the fly. It is because the transmissions do not have any form of synchronization. You have to stop to select a new gear.

Thank you for the prompt reply and correcting where I was wrong.. is the band is drum a very safe reliable easy to maintain brake (band)

just buy one of these and find where it attaches to brake lining.. bolt it in and done? Safe reliable brakes

Safe and reliable are relative terms. Most bicycle brakes have more stopping force relative to weight than a garden tractor. I've never relied too much on garden tractor brakes, particularly the parking brake, but they are fully mechanical linkage, so no hydraulic lines to blow out.

 

Easy to maintain is also relative. The process of adjusting them is simple enough, it's just a nut to tighten or loosed on a threaded rod. Access is the issue, it's not in a super-easy to access spot. My hand fits fine, but there is precious little room to swing a tool. If you flip the seat pan up it should all be on the left side. 

 

The lining you linked to is just the friction material. The old would need to be removed from the band and the new glued down. @rmaynardalso sells the linings. Brian at K&B@76c12091520h will sell you a whole, ready to go band with lining.

Sadly the brake is the weak part on these machines. You were correct when you said these tractors can tow much more weight than they can stop. I have always heard that an 8 speed can pull 10,000 lbs without damaging it, but I promise you that brake band won't stop it. 

 

The brake (if it works properly) stops the bull gear in the transmission. If one wheel slips, the differential will not hold the tractor from moving. 

 

Of course during "normal" use on reasonably level ground, the brake is sufficient. Most of us don't regularly adjust them until we notice it won't stop...

I remember one time when I was maybe 10 or 11 years old, and still pretty new to driving the tractor, I ran the front of my dad's 310 off the end of the carport because the brakes didn't work at all.

Yep. I had a similar experience. 

 

My 314-8 had the brake adjusted about as tight as it can be without dragging. That tractor has a smaller rear and larger front pulley and will go about 15MPH. It will slide the tires on my gravel driveway. Even so, I would never trust it to stop with more weight than the tractor by itself.

Thank you for the detailed info. Would this be the exact process i need to follow on the 856?

Yes. I just skimme the video but it looks like a good set of instructions for that job.  Bob @rmaynard ?

[rmaynard 17,247]

Well, I saw several things that I did not like. First, I did not like the way that he inserted the seal with a punch. I always use a piece of PVC pipe to set a seal. That makes sure it's set at equal depth all around. Next and most importantly, he didn't use a Bob Maynard brake lining. My linings are 1.5 inches wide. His 1 inch lining will give him 30% LESS braking. Also, he complained about how hard it was to get the old glue off, then he used the same type of glue to put the new lining back on. My opinion is, if you are going to do something as important as brakes, don't cut corners. Do it right.

And this is  why we don't take YT for gospel. Aside of the things Bob has already mentioned he did not tape the keyway off to avoid nicking the seal.

Although it's never a bad idea to put one of B-100 Bob's linings on I never change out an original just because it's grease soaked. I have a method of cleaning originals using a mineral based solvent and burning the old grease off. 

If this happens yes ... replace.

Just remember these tractors have Fred Flintstone brakes and you'll be fine!
