hi, I suppose that would work, but I'm not schooled on all the forms of additive octane boosting. What we need is a fuel that lights off easier, and many of those octane boosters are referring to the anti-knock aspects of octane (as in what the lead used to do for us, which we don't need in these lo...

Hi, I bet not. He'd have to field the awkward question as to why it might be that someone would come in and swipe driveway gravel. That one would probably be question #2, after 'any idea who dun it?'..... So, the cops go to 'who dun it' and ask 'did you?', and get a 'yes, because of no pay' and then...

Hi, Well, one can adjust these 'by feel' once one has done it enought times to learn what 'feel' feels like! :P The sequence is pretty straightforward. You want the clutch pack to disengage before the brakes come on. The adjustments are pretty small, though, so if you don't do it just right you have...

Hi, Lead isn't what helps here, it's fuel volatility and vaporization. Modern fuels aren't as volatile as the older stuff was. Doesn't matter much to computerized fuel injection systems, you see. It does matter to our old iron with carbs, esp. updraft ones, though! I find that using the higher octan...

Hi, Was the left track driving? I presume it turned sharply right when you tried the right side steering, indicating that power is getting to the left side. If the left is not driving well, you're in for a clutch job for sure. It may be that you have an oil leak on the left side that swelled the fib...

Hi, I used to do the opposite - change the charging part of the system over to 24 volts and run the batts in series all the time. I tapped off only the ground-side 12v batt for the accessories (lights and such). This also worked like a charm. It was ther silly series-parallel switch that was the pro...

Hi, I know about Jorde's, and I know there stuff is good, but I don't need to contact them for anything for myself. Since my wife has her own screenprinting and sign shop, I just make up my own stuff as I need it. Handy! :) What I was thinking is that the reverser is a fairly rare item on a wheel tr...

Hi, Boy, it can be really hard on the rear ends. I saw a lot of 435's with toasted rear gears when I was a kid. Deere made an Ag version of the 430W (row-crop utility) with the Diesel they used in the 440's in it, and called it the 435. It was advertised as a HAYING tractor, and even came with a 100...

Hi, My 420c still has the decal attached to the left side battery box sheetmetal. I don't recall the exact wording, but it basically amounts to 'if you work the reverser lever without using the master clutch you will be screwed'. I'll write down the actual text and post it over the weekend. Maybe I ...
