Earth Tools TDS (Tiller Depth System) and BCS PDR (Precision Depth Roller)
BCS walk-behind tractor with 30" tiller, with
Earth Tools TDS installed (ALSO FITS GRILLO 30" TILLER)
At last, a project we started in 2014 finally comes to fruition! We are very pleased to introduce the Earth Tools Tiller Depth System, which enables the tiller implement to achieve very precise depth settings AND “press” the seedbed perfectly for use with precision multi-row seeding equipment. This allows the tiller implement to perform SOME of the functions that the Power Harrow has become famous for. A similar device is offered by BCS (the BCS America “PDR” [Precision Depth Roller])…but our system is much easier to install & remove, is easier to handle, is more versatile, AND it is much more affordable…but we offer the BCS version too, if you just must have “everything BCS brand”!
For starters, our system comes standard with a SMOOTH roller made of tubular aluminum, which will not “fill up” with the material discharged rear-ward out of a tiller. Thus, we were able to nestle the roller right up under the tiller rear flap, to “shorten” the whole system up as much as possible (6.5” shorter overall than the BCS version), therefore making it easier to handle (and less prone to whacking your shins on when maneuvering the machine!). To deal with the fact that a “solid” roller may build up soil on it in damp conditions, we have an adjustable scraper-bar oriented over the top of the roller to scrape off excess soil. Even though the smooth roller makes the Earth Tools TDS a few pounds heavier than the BCS version, the fact that it is so much shorter (closer to the tractor fulcrum/axle) makes the “perceived weight” (that is, the amount of effort the operator has to generate to lift the tiller out of the ground) LESS than the BCS version. With EITHER the Earth Tools OR the BCS version, the weight the operator has to deal with when lifting the tiller obviously increases when a roller is added to the tiller…and if desired, we offer engine-side counterweights to offset this. (See below in pricing section) Our front-weights are “suitcase-style”, so they hook right onto the engine bumper with no tools needed. NOTE: IF YOU HAVE VERY SOFT / SANDY SOILS, FRONT COUNTER-BALANCE WEIGHTS WILL DEFINITELY BE NEEDED – OTHERWISE, THE GROUND-PRESSURE OF THE ROLLER MAY “SQUISH” THE SOIL OUT TO THE SIDES TOO MUCH, PARTICULARLY ON RAISED BEDS. THIS GOES FOR BOTH THE BCS PDR AND THE EARTH TOOLS TDS.
Also, our TDS mounts to BCS 26” OR 30” tillers (now available to fit Grillo 27” & 30” tillers as well!), and once the mounting frame is installed, the roller assembly mounts or dismounts from the tiller in less than 2 minutes, making it easy to convert back to a “regular” tiller for deep tillage and the best handling (lighter, shorter). NO modifications or changes need to be made to the tiller in order to mount the Earth Tools TDS or to make it work properly.
Cage-type roller is used for weed-control applications
What’s more, for WEEDING applications, we offer an optional Cage-Type Roller, which is made up of horizontal bars with space between them. This still offers precise depth control but minimizes soil contact and leaves the soil “fluffy” to that uprooted weeds have much less chance of re-rooting. The two roller types can be switched out in the frame in less than 2 minutes, with just 2 bolts.
The range of adjustment our TDS system offers allows 11 positions, ranging from 0 to 3” of tilling depth, and will also lift the tiller off the ground for transport. The depth increments are roughly 1/3” apart for very fine adjustment. The lever and locking system are vertically operated & oriented, for best ergonomics. The BCS version (the “PDR”) has a greater range of working depth: 0 to 7”…so it is capable of doing a “deep till” while the roller is still mounted. This is good in the sense that the BCS version is quite time-consuming to mount or dismount from the tiller…by comparison, we made the Earth Tools TDS so that it can be installed or removed in a couple minutes, so that folks who wanted to “deep-till” can just pop it off and have a lighter, more maneuverable machine for deep-tilling.
Note: Since the Earth Tools TDS is not a “BCS-manufactured” accessory, BCS has stated that if any damage to their tiller implement occurs during the warranty period as a result of the Earth Tools TDS being mounted to it, this damage will NOT be covered by the BCS warranty. However, since we at Earth Tools stand behind our products, if such damage occurs during the warranty period, WE (Earth Tools) will cover the repair.
