Hey, your machine, your choice. For a plain single shear plane style the manufacturer often specs a plain bolt. Kubota specifies a 1/4-20 Gr. 2 bolt for my auger and a 6mm 8.8 bolt for my gearbox input. I know of a different but very similar model where Kubota specifies a "Special grooved Gr...

I'm not sure that's true of even plated grooved shear bolts. It's certainly not universal of stainless steel bolts. And it's completely wrong if the bolt is metric. The groove is more than "slight" -- in my experience they are close to the full thread depth. IE a 5/16" shear bolt will be...

Not so much: law of supply and demand. Even if this particular bolt was made in the US of USA made steel the lack of and/or increased cost of imported versions will drive up prices.

There are two kinds of shear bolts: One is for a simple face-to-face joint with a single shear plane, as between two flanges. Plain bolts are typical in this application. The other kind goes through a shaft and coupling. The bolt has two shear planes, separated by the diameter of the shaft...

A little time modelling with paper and pencil or CAD software can save a lot of grinding. And there are a number of online calculator websites that can help calculate the hydraulic forces and pressures required. When I built mine I had the geometry pretty much worked out in advance...

I have both a front mount and a 3ph mount. The "handling" is decidedly different! Turning the front mount in deep(ish) snow is less effective due to the exaggerated rudder effect. The steering wheels are trapped between the "rudder" (ie: blower sidewalls) and the rear wheels. Lifting the...

No. The tractor is only carrying the blower during tranport anyway. When in use the blower is self-supporting.

Do you have the style with a collar that pulls back to retract some balls? You may need to clean or lube things. I prefer the style with the simple spring loaded pin on one side.

I change it every spring before putting it away and check it again in the fall when setting it back up. More because I want to avoid any moisture issues than any leakage of lubricant -- that would be readily apparent. There's not too many places the gear lube can go and the box is right there...

The carbide used for milling wood is a different grade than the carbide used for milling steel. Wood bits are typically C2 to C4 (softer, tougher and less likely to chip in an interrupted cut) whereas steel milling bits are usually C6 or higher (harder, more brittle, holds edge longer in an...

I wouldn't go more than 65° for sure, especially with mild steel. IIRC, I think I settled on something closer to 45°. But mine is also home-grown and I didn't experiment with various angles to really say what is the best. Whatever I settled on depended heavily on what angle was achievable given...

Oh, so to actually answer your question: No. To lift more weight you need to increase the pressure or increase the cylinder diameter (ie: larger surface area for pressure to push against). Increasing the cylinder diameter will also increase the volume required to fill that cylinder, so it will...

Don't confuse pressure with flow. Flow rate determines how fast a cylinder will move, pressure determines how much force a cylinder can exert. Volume of the pump determines flow rate, force of the engine determines maximum pressure (up to the relief valve setting of course). Let us assume a...

What he said. I would add: use chain-specific lubricant on any drive-chain. And after many years of use, you may need to replace the shoes or cutting edge. Depending on how much road salt the blower has seen some scraping and painting may be warranted. And if you deal with wet snow, an...

Ooops. Double post. Deleted.

I'm having a real hard time buying this one. Evapourating alcohol out of water is called "distillation" and requires a temperature of around 80°C or a Mongolian still or the addition of a high concentration of non-iodized salt. The distillate (alcohol) must be removed immediately because the two...

Yup. Yup. Just going to lift the front of the tractor off the ground. Typically your downforce is inherently less than your lift anyway. The piston area is reduced by the rod diameter when retracting the cylinder.

Yeah that's the device. And no, I don't think downpressure is really so much of an issue with the typical FEL build. But that's how they come. (Unless there's another style were one relief valve is replaced with a check valve. Dan?)

It goes between the control valve and the cylinder on both lines. IE: UP line from control to cross-over relief valve inlet port 1; outlet port 1 to cylinder UP. Same with Down -- from control to cross-over inlet port 2, outlet port 2 to cylinder down. It actually contains 2 relief valves...

Maybe it's seized? <lol>
