    Waratah 622b / HTH20 processor feed rollers weak

    Usually a tired drive motor will stall and the others will spin out, usually if you grab the feed roller and try and roll it back and forth and has a lot of play that will be another sign things are not ideal. Could also be a spool or coil on the head not working well when it gets hot which is...

    Tigercat yarder

    I seen someone on the book of faces compare it to a 071 and how it was better and had a good laugh. You need those guys in the bush learning never know if that one guy is going to make an awesome hooktender if he was never out in the rigging. Can throw a grapple carriage on any yarder if that's...

    thunderbird clutch conversion

    I think on the main clutch they did, but I know on our haulback clutch we pulled it wasn't to bad to pull.

    Tigercat yarder

    From what I have seen running a motorized grapple on a harvestline "junk" when you are digging around grabbing logs the carriage takes a hell of a beating so add mechanics wages into keeping the thing running. Also they don't do low deflection settings at all tend to really tear up stuff.

    Tigercat yarder

    None, less line pull, slower, weighs more, takes up more room on a skinny trail and i haven't seen a guyline winch yet so if your in a shitty spot hooking to stumps life is going to suck.

    thunderbird clutch conversion

    On a TSY 50 used for grapple yarding have had those crack over the years just welded them up and seemed to be holding up. edit Caught the cracks before they looked like that.

    Going to be feeding it with a machine on the hill i take it? That was one of my many issues with the harvestline I couldn't swing the machine to get the grapple to flip over a couple of feet to get the grapple on the wood.

    After running a carriage grapple on a harvestline for a year and a grapple yarder before that, i would have to say there is no real advantage to the motorized carriage unless you really like fixing broken carriages after bouncing them off the ground, they need a ton of lift can't drag it through...

    Electric winch hauler

    Well put, the original grapple carriage design is a joke, the lack of pulling power is a joke, the fuel economy is a joke (35 liters per hour), the amount of lift it needs is unbelievable (deflection that would be more then enough to grapple with a swing yarder is not enough), the speed is slow...

    Electric winch hauler

    Hopefully has more linepull then the ems harvestline, not very impressed with the lack of power with ours. Also looks like it needs a lot of room to setup also like our harvestline.

    I was wondering how that hyd tower works our EMS harvestline on the tigercat carrier burns a huge amount of fuel for what it does.

    Be cool to see one out here, but i think you will run into having to rebuild the all the roads just to walk one of those around. A little 12' wide yarder can make a regular haul road look pretty narrow sometimes.

    A really good op and hooktender on a grapple yarder can make a huge difference. Murk100 would probably have some good tips to. Hope that 155 works good for you.

    For the grapple johnson industries has a pichttp://www.jlogging.com/gpspec1.html showing how the cable is run thru the sheaves and the pic also shows what they call the 3way slider which your main, slackpuller and closing line are all attached to using knobs. We always kept spare closing lines...

    I ran a thunderbird tsy 50 with a different contractor for a couple of years and it would have done pretty good on this block.

    Road and landings are at the bottom and a conventional grapple yarder would have done a good job on this patch. We tried a harvestline with the Hawkeye and didn't have the power to get the grapple up in the air at the backend. Found it needs a ton of lift.

    Think it is the second one on a 855. Packs between 2/3 to 3/4 of a tigercat 630 grapple down the hill.
