Coast valve or Engine hand throttle?

This is from the brake fluid thread ...but since I am going off on another track I started a new thread.

I have not changed my brake fluid. For that matters, I don't think I've used my "brake pedal" three times since new.

But changing fluid might be a good idea. Mine looks new.

Our RTV would be just as good using a wooden brake set-up !!!!

TwoGuns, I guess you don't have any 1/2 mile long hills or grades. Tween me and the river is a long hill where I can put the RTV in neutral and coast for 1/2 mile or so. This is better than putting up with the engine braking when you let off gas a tad. Engine braking sure does come in handy when pulling a trailer full of wood down the same hill. So, instead of a coast valve I'm thinking of getting the throttle control like BC has. Keeping the engine RPM up but still lets you let off the gas to effectively slow down without engine braking.

Does that sound right?
 
Wrong! The engine braking is controlled by the pedal position regardless of engine rpm. The same pedal does increase engine rpm as it opens the swash plates to increase speed. The rpm is actually reduced by spring force on the engine itself. At least that is how I understand it to work. The hand throttle is used to maintain rpm while the pedal will work the plates for the sweet spot where speed drops but torque from the hystat increases. I could be thinking out my butt so free advice should be checked.:confused2: You can shift to neutral and use the brakes to control your speed. Works great for sneaking up on trespassers and critters. I shift to neutral and shut off the engine and just freewheel.
 
Muleman is right...I use the hand throttle to keep engine speed up while snow plowing and the engine brakeing will still toss me thru the windshield if I'm not careful.

The hand throttle does NOT minimize the engine brake effect.
 
Dang it. Thanks for the info guys. I guess a coast valve is in my future.
Any suggestion on the best place to buy a coast valve?

It sure is quiet when in neutral and coasting. With the weight of the RTV you get moving pretty darn fast. This is about the only time I've had to use the brakes, and I sure do use them on the coast down the hill.
 
Mulemans right.The spring tension on that check valve will determine the amount of engine braking you will have. The more spring tension you have the harder your engine braking will be and vise-versa. You may need to "tune" it to your liking.
 
I like my engine brake.

"IF" I want to coast, just don't get all the way off the pedal. Also like the idea of just leaving it in gear and getting out and doing my thing. No shifting in nuetral and HAVING to put the parking brake on to keep it from
rolling. Just leave it running and it automaticly has a brake on. And I like that.
But honestly, ain't much "free rolling" down here in these Louisiana swamps. NOW, when I go across the river into the hunting land over in Mississippi,
yep, I really appreciate the engine brake.

I like the idea of getting out without having to set the emergency brake or take it out of gear. That works most of the time. Once in awhile the RTV will coast a bit and I have to set the brake to stop it. No rhyme or reason as to why most times it stops and other times it does not.

I can't watch your you tube video jamie as I am behind a firewall. I will watch it later tonight.

But going down hill and letting off the gas just a little the engine brake will still kick in. If the grand kids are riding with they could get thrown off the seat as it is a very abrupt engine brake. I got the RTV used and the passenger seat belt is whopper jawed (won't fasten) and that adds to the issue. I know, I know ...I should fix (or replace) the seat belt.

Muley, can you post those instructions ...or email them to me again. I can't seem to find them. :hide:

You didn't see my camera did you?:yum::yum:
 
Got em. On the road now though. I'll try to remember to save them to my home computer when I get back. Thanks muley. what camera? LOL
 
Chikming in late here due to a death in the family.Doc it may seem like a PITA but you get used to it real fast and personally i like the idea of the hydro braking on the Bota.It seems wierd at first but you will get used it it real fast and actually come to appreciate it I think.
I know I did on mine and rarely even hit the brake pedal.

Mine seem erratic. Sometimes it throws you on your nose, other times it coasts a little, other times it engine brakes a little, no biggie. Hoping the adjustment will help. I hardly use my brakes at all either, unless I put the RTV in neutral and coast down the hill. It's about a 1/2 mile coast. Pretty cool and seems easier on the RTV, and easier on the passengers.

Here are the adjustment docs muley was kind enough to send me a 2nd time.

The camera that walked away about a month ago.:hammer::hammer:

At least your camera is making someone else happy... A friend of mine a couple of weeks ago shot at a doe, missed her clean, and instead nailed his camera that was fastened to a tree across the food plot. :pat:
