JDcrawlers Messageboard

Hi, Oooh. Now I want one, too. Didn't want one when I thought it was a Struck, but this is a more serious machine. Wonder what they cost? Also wonder if there's a 6-way PAT blade option. I didn't see any blade or loader options on the website, though..... Found one site on the web with some pix of t...

Hi,

MawDang.

There was another thread where we were talking about gas issues, and I should have thought to point you in that direction as a possible culprit. Sorry about that, chief!

Hi, I was going to post a l-o-n-g reply on the steps to correct this and other problems once-and-for-all. I decided not to spend the time, though. It would have started with a 420c and ended with everything upgraded such that you wound up with a JD350C at the end, following the path that Deere took ...

Hi, That'd be a cracked center insulator causing that. Under atmos. pressure, the thing fires from the center to ground electrode just fine. Under the much higher (15 vs 120+ PSI) cylinder pressure, the spark fires out the crack in the insulator to the side of the 'tube' (for lack of a better word t...

Hi, Looks like a modern Struck mini-dozer painted up to look like a Deere. Not that that makes it any less cool, though! I've been thinking about taking an old original Struck (aka the world's most useless dozer) I have kicking around and merging it with an old Deere 110 lawn tractor to make a track...

Hi, If you look closely, you'll see that the Lindemann pads are stamped and have not so much a grouser, but a curl at the extreme end of the pad. The later (and what we'd call normal these days) pads are forged and have a vertical cleat some distance in from the end. The curl on the Lindeman pads wi...

Ray, So, if you're in 3rd gear and going backwards, then you had to be using the reverser, which is OK. The thing is designed to allow the machine to move itself backwards in any gear - although I don't much like using 5th gear in either direction as it seems way too fast for the tracks to me! When ...

Hi , Does it really matter? The paint won't stay onto the pads for long anyway, even for a show machine. So, unless one is sticking the thing inside a museum, I'd opt to leave the entire track ass'y unpainted. Take the rails off, paint the frame and such, and then put the unpainted rails back on. Or...

Hi, Yes, these things started as 3-roller and they just pulled stuff. Then, they added a light blade, then a heavier one, and 3rd parties started making all sorts of stuff (most of what you see popping up in the upper left of the site is 3rd party goodies). So, the thing grew a 4th roller, then even...

Hi, With the differential style reverser, the clutch packs, the differential gears, and the entire housing that holds the mess together is running as one really fat shaft when in forward. In reverse, the clutches change things and the forward half turns forward, then the tiny differential gears come...

Hi, You should be OK as far as damage you might have caused (not to say that there isn't any previous damage). The thing would have had the clutch packs both in the halfway position, and so acted like a neutral. Sounds like nothing grabbed suddenly, so this should not have hurt anything. The real pr...

Hi, You mean, they're *not* supposed to do this sort of thing! Heck, I just figured I'd missed the section of the manual where they mention the oil peeing part! :P It's not just the old iron that does this. New stuff is equally happy to pee on you. I have a brand-new JD/Frontier sicklebar mower. Bou...

Hi,

Oooh. I bet that caused a few choice words to pop out! You find that out by trying the gears with the case still on the bench or did you wait until after the machine was reassembled?

Stan

Hi, Sounds like you have the differential-style reverser. These work by using two clutch packs, made of alternating fiber and steel discs (like a motorcycle ot auto trans clutch). One is for forward motion, and the other is for reverse. In between the clutch packs, there is a set of spyder gears. Th...

Hi, Cool! :) As fer as the two valves go, how would you do it with only one and have a double acting cylinder? The modern spool control valves still have two valves inside. It's just that these old girls have two single-acting valves out in the open with control rods to the lever. You can adjust tho...
