Currently, devastator models are only compatible with non-chopping heads.
Most likely the engine oil level is too low-check engine oil level and add oil as necessary-oil level must be on the “full” mark to engage the oil level sensor.
Gear oil ISO (220) or equivalent.
Use less than 30 p.s.i. to reduce the amount of "splattering".
The key set is taped to the valve cover.
Set the rod to operate at 1/2" below soil surface.
Yes, you can do whichever best fits your operation. If you take the seal out, you must grease every 50 hours. If you leave the seal intact, fill the wheel assembly with grease before using. No need to grease again until you replace the bearing.
In most conditions mount the wheels offset, front hole and rear hole. In some conditions, the wheels perform best when mounted one front hole and one middle hole.
Center the blade on the hub, so that it is concentric when it turns. Place the knife top up to the coulter blade; so that the knife and coulter blade just slightly contact each other at the tip. Then as the coulter blade rotates up the knife, you want to have a gradual gap between the knife and coulter blade. Also the knife needs to be centered side to side on the coulter blade.
In some conditions a knife scraper is needed to keep the residue from "dragging" up on the fertilizer knife. 2970-133
Tri-fold markers are equipped with "restricted" elbow fittings on the hydraulic cylinder, to limit the marker from rapid operation/movement. If the marker operates slower than 8 seconds; then drill out the restriction with a 1/16" bit. Adjust the hydraulic oil flow to operate the marker no faster than 8 seconds.
Poor seed germination may be caused by seed being too close to like residue (ex. corn following corn) which can result in alleopathic poisoning. Use a residue clearing device which moves residue instead of incorporating it into the soil to improve germination.
If the planter unit and or frame mounted coulters are running too deep, properly adjust coulter height and ensure that in operation the planter hitch is set to the correct height (consult the planter's operator manual). If the double disc openers are excessively worn, replace the openers. If the soil is too wet, allow the soil time to dry.
We design our products to operate on a level planter and unless the planter is level the attachments are not going to perform successfully.
5-5.5mph, speed affects seed spacing and depth
