Default Ram steer

Who can tell me about ram steer? Sounds like a power boost for an old brake steer cat.

It uses a hydraulic ram to control the turning angle of the drag relative to the cat. Sort of like an articulated farm tractor. You bend it in the middle, and it goes around the corner.

With brake steer, you're braking one track to turn the cat, and then the drag has to follow.

Don't feel bad. My first one was a 2x4 with some chainlink attached, attached by rope to a snowmobile.

Default Re: Ram steer

actually the steering on most all twin track snow cats isn't brake steer but planetary steering. You drop speed on the inside track by about 20 percent and increase outside speed by 20percent. What folks call a steering brake isn't really that ,but a band locking a planetary drum to drop inside speed pushing power through another set of planetary's in the center differential to give the overdrive to the outside track. This way both tracks are being driven in a turn. This system sucks up a lot of horsepower and the steering bands will slip and heat up loosing their friction if used a lot the oc manual stated to use a short jerking action to make turns and not to slip the band too much or accelerated wear will happen I find on our wind blown hard pack that I have to make plenty wide turns because of band slippage, I actually broke a band last winter.

Default Re: Ram steer

this is a ram steer from a shop industrial (mogul master) drag.

basically a hydraulic RAM that STEERS you.

balanced ones have the hoses crossed so the machine steers the same in both directions.

if it had one ram it would steer quicker left or right as the volume on the in stroke displaces less fluid.

notice the end has a swivel for pitch.
the round elements seat into pockets for Yaw.

I intend to install an orbital valve and steer my 2100 project like a car, or tucker, ST4 ect...

Default Re: Ram steer

really don't think you need ram steer-----ram steer is great for smaller cats pulling way to big and heavy drags----years ago clubs would buy bombi cats to groom with and than put ram steer on them ---a bombi was not built to pull a load--so they would burn out brakes---and would loose traction turning because of breaking one track---ram steer keeps both tracks driving all the time-----don't know where you go with your cat ---but taking every other silde slip plate off your tracks will help you turn better---and alternate them inside and outside-----when cutting down pb. tracks I 45 the edges on the cleats it will turn easier and help it not walk out of a track on hard ground---here is a pic. of my trail no ram steer needed---this pic.was using my geo tracker on mattracks I also use a sv200
