Top link adjustments

[rjkobbeman]

the title states "Top Link Adjustments"...to me this indicates the "Toplink" on a 3 point hitch...and if you shorten the toplink on a 3ph it will tilt the implement forward thus making the forward facing blade (and or scarifiers) cut or dig more aggressively...lengthening the "toplink" will lessen the aggressiveness...again this is assuming the tractor is being operated in a forward moving scenario...

Yup. Shortening the top link will rotate the top of the implement forward... and cause all ground engaging devices to bite even more.

and cause all ground engaging devices to bite even more.

Unless it's a disk, in which case it lifts the rear out of the ground

Reality is, changing the top link length does different things with different tools.

Hook up the tool you want to use, and EXPERIMENT until you figure out how to make it do what you WANT it to do

That's half the fun of having these toys

Hmmm, thought the OP was talking about a rake and a box blade. Sorry.

As stated above, the reaction to toplink length differs among implements. So again, please refer to the opening post please. Specific mention was made to rear (scraper) blade and (landscape) rake. Your mention of scarifiers means boxblade, which changes the toplink equation.

With scraper blades and landscape rakes, it's simple geometry involving the curve of the blade/tines. Moving the top of the A-frame (toplink) changes the angle of attack of the blade/tines. Shorten toplink on rear scraper blade (not boxblade) and it will scrape - maybe even bounce. Less aggressive. Lengthen and it will cut. More aggressive. Shorten toplink on landscape rake, and it will rake. Less aggressive. Lengthen and it will dig. More aggressive.

sorry, but on this planet (Earth, the third from the Sun) the opposite is true...

a scrape blade is no different than the cutting blade of a BB...

Here's a good job for you then. Contact all the manufacturers of back blades and landscape rakes on Earth, and tell them their operator manuals are in error. Here are two to get you started, since you clearly believe that LandPride is mistaken on pg24 and that Woods is wrong on pg8. A word of advice though; you are likely to encounter skepticism if you mention anything about them being on the wrong planet.

Simple, easy to understand , and correct. At least this is how my back blade works in Vermont. Maybe there are geographical differences but i doubt it :laughing:

A few points...

I don't need a job but thanks anyway...

I don't have adobe (or other product on this system) capable of displaying .pdf files... so it's pointless for me to follow the links provided...but I'm sure the references you cite qualify your statements (can't see you posting them if they didn't)

I never directly referenced a "landscape rake" having never used one...any reference to one was inadvertent on my part...

I do acknowledge that a scrape blade CAN be set (shortened toplink) TOO aggressively to be effective and it will "skip" as you cited...in the same respect lengthening the toplink excessively will roll any (forward facing) blade backwards to the point it (cutting edge) will no longer make contact with the surface...

This is a good opportunity to learn, but I don't know what to say without hurting feelings...

A lesson learned can be valued for life

Adobe reader is free and available for nearly all operating systems. No valid reason not to install it. You would be able to view many informative pdf files, such as operator manuals, parts manuals, etc.
