Signature Rotor

Features & Benefits

The Signature 6000 Series Rotors have top quality features including Acu-Cover nozzles for better close-in watering, continuous full or part-circle options in one head, and the NIR2 adjustment feature. The 6000 Pro series rotors are constructed of high impact plastic and all internal metal parts are made of stainless steel. The built in slip clutch protects the gears and motor from damage when adjusting for a part circle. If the rotor is manually moved out of position it will automatically reset to the defined pattern. No tools are required to adjust the arc from 40 - 360 degrees by using the easy to use Click-Set disc. The 6000 rotor comes with a rubber protective cap. In addition, the NIR2 eliminates the need to remove the cap while fine tuning the radius and inserting the nozzle.

  • NIR2 feature (Nozzle Insertion/Radius Reduction) on all models eliminates the need to remove the cap for nozzle adjustments.
  • Seven optional low-angle nozzles (13 degrees) for windy areas or for throwing under trees.
  • Highly reliable water-driven gear motor (over 200 million gear stacks produced).
  • Pro 6012 pops up a full 12". Ideal for shrubs and ground cover areas; at the base of hillsides where risers are not appropriate and where liability is a concern
  • Click-Set collars are quick and easy to adjust.
  • Continuous 360 degree rotation or part-circle adjustable 40 degrees to 310 degrees.
  • Ratcheting slip clutch protects gears and motor from damage while adjusting turret for part-circle adjustments - wet or dry.

Great replacement for Nelson sprinkler heads
My husband said they should work great and is using them when he needs to replace his old Nelson Sprinkler heads.

Very cost effective
Last standing Nelson 6000 user after trying many other brands from other irrigation companies and home improvement centers. I have found Nelson 6000 to be the longest lasting, easiest to set-up, and most reliable.

Same as Nelson 6000 / Interchangeable
Installed perfectly into the existing Nelson sprinkler housing. I didn't have to dig anything up, just unthreaded the old broken Nelson head and inserted the new Signature/Nelson unit. I adjusted the pattern and was done in 5 minutes.
June 1, 2015
I have used Signature 6000's for years. My Ace hardware told me they didn't make them any more. I found them with your company. Question: when rotor will not turn is because top is to tight on spring correct ? They are the easiest I found to adjust.

Good product
This was my first time replacing sprinkler heads and this product was easy to use. I do wish instructions had come with to explain the different nozzle size and how to adjust/install, but I was able to find them on Sprinkler Warehouse's website.

charles s on Apr 21, 2017
this sprinkler is the same as the "Nelson" sprinkler I have installed over 25 years ago. They are easy to adjust and far superior to "Rain Bird" or any other rotor sprinkler now carried in most, if not all "home improvement" stores. This type sprinkler is no longer offered in retail stores or even irrigation warehouses in our area.

T A on Apr 13, 2017
Sprinkler Warehouse was recommended by my brother<br /><br />The Signature heads are very easy to adjust. My original system was installed with Rain Bird heads. Rain Bird heads are a nightmare to adjust and maintain.
C R on Apr 10, 2017
I have found the Nelson Signature 6000 to be more durable than the other residential Rotor sprinkles. I think it's because of more gear reduction rotating the head.

sandra C on May 4, 2018
how to adjust the rotation on a signature pro 6000 sprinkler head?
C B on Sep 11, 2011
BEST ANSWER: All you have to do is adjust the two collars inside to were you want the sprinkler to stop on each side. There are two of them and one is for the right side and one for the left side of the rotation. I hope this helped.
How many do I need to order to get free shipping?-----RAY---
ray p on Oct 17, 2011
Why do most of my 6000 sprinklers stick in the up positon after they turn off? I have cleaned the shaft and seal but did not help. The springs have all been replaced.
A shopper on Apr 22, 2012
BEST ANSWER: I can not say for sure but I think dirt might be getting into the groove where the horse shoe shaped tool goes. The tool is used to hold the upper part of the unit extended while you change or adjust the nozzle. If the groove gets dirt in it it could possibly hold the head up.

Cliff Hoole
My system is a Nelson Unit. Is Signature the replacement company for the products?
Robert S on Jul 1, 2014
BEST ANSWER: In general the answer is yes. There are still some of the higher cost models of sprinkler heads, such as ones with a stainless steel riser, that just Nelson seems to still make. With most of the rest, the Signature brand works just the same as the Nelson brand.
when time is finish the heads don"t go down ?
luigi b on Jun 30, 2016
BEST ANSWER: It probably has some dirt or plant life inside. Unscrew the top[ part at that big nut and take apart to clean.
There may also be a dig or gauge in the cylinder that's stopping it from going back down. maybe even spray with a little WD-40. Other than that ?? maybe kick the livin' you know what out of it and replace with a new one.
One last thing you my have too much water left in the line when it goes off and the pressure is keeping
it or them up. You may have to put something in the line to relieve the pressure and water when the valve shuts off. Jack
Does anyone know where you can get replacements for the removable rubber cap (with threaded screw) on the Nelson 6000 heads?
nonickname on May 15, 2013
BEST ANSWER: I bought some a while back from this site and I have seen them at a local hardware store in a blister pak at outrageous price. Be careful the current offering of later model will not fit.
I need two (2) rubber covers for Nelson now signature 6000. Damaged them with lawn mower. Can I purchase covers only?
A shopper on May 28, 2012
BEST ANSWER: I don't think so because it is such a small part. They have also improved the design so you may not have the same style. What I have done is have spares on hand because shipping is too much to buy just one at a time. Just borrow the caps until you have to change out one complete sprinker unit.
When will these be back in stock?
Terry G on Aug 10, 2011
BEST ANSWER: How silly is this? How would I know this...only SW would.
What type of lubricant can I use to keep the heads from getting stuck in the up position?
A shopper on Oct 21, 2016
BEST ANSWER: No opinion about lubricants. However, Most likely the issue is debris or deformation. If the head is too low, dirt or debris may prevent retraction. Movement of the ground on slopes or from roots may cause the head to jam. I have found over time, heads tend to stick. Best solution is to check for the above causes. If no cause can be found, replace the head.

This is the best sprinkler head on the market because of the ease of setting the scope and ability to easily change nozzles and range.
how do I remove top of sprinkler head so I can adjust the flow?
A shopper on Jun 7, 2014
BEST ANSWER: It depends on how long ago you purchased the sprinkler head. The newer models have a top that is held down by flanges. Turn the head counter-clockwise about 1/8 of a turn and the flanges will move to a position where the head lifts off. On older sprinkler heads, pressure clips all around the inside of the top "snap" it into place. These are harder to remove. Do not try to lift the whole top vertically. Lift the front of the top - the point that is over the spray nozzle. It takes a tight grip with 2-3 fingers or a thumb.
I have nelson 6000 heads, are the tips interchangeable ??
A shopper on Oct 24, 2018
BEST ANSWER: I think they are, as I recall, only the brand name was changed at first and later the cap was changed (or maybe it was the Pro version that changed the cap). I have bought all the versions over the years. I'm sure the tips fit, but don't remember if the water flow rating is the same. I know the top caps are not the same. Nelson pops on and the Signature screws on. Hopefully someone else will jump in here and have a more concrete answer for you.
My pump has a flow of 50.76 GPM how many heads per zone should I use?
A shopper on May 7, 2012
BEST ANSWER: If you go to the 6000 page and look at the PDF manual on that page it has the specs. Depends on what nozzle you use and water pressure. The common nozzle is the #7. I use them on my own home system at 50 psi water pressure with #7 nozzles it has a 3.1 gpm. I am on a well so if you are on city water it will probably be 2.7 gpm at 35 psi. Divide your 50.76 gpm by one of them numbers you will come up with about how many heads. First look at that manual. There is two kinds of smarts, Book Smart and Experience Smart. Become as book smart as you can and then the experience smart will come easier.
How do I remove a sprinkler head (Nelson) that does not retract back into the ground after cycle?
A shopper on Sep 12, 2011
BEST ANSWER: Every now and then I have a sprinkler head that will not retract. First I try to clean the shaft and spray it with WD40 then put pressure on the top and it will pop back down. If it continues to stick. I remove the head and replace it. You can do it two ways. 1. Remove the dirt from around the sprinkler head untill you can see the hose conection at the bottom, then you can unscrew the entire assemble by turning it countrer clockwise untill it is free. 2. The other way is to unscrew the main housing at the top of the spinkler head body. You will note that there is a grove in the shaft when the sprinker is extended, this is where you slide on the locking key ring to hold the shaft up. If you dont have a shaft key, they be careful when unscrewing the main body cap. It is spring loaded, but you can keep it down by keeping pressure on top. The once you feel the cap release, easy up on the pressure. Note: The locking key ring makes it much easier.
nelson 6000 how many in a case ?
LARRY Y on Jul 21, 2016
BEST ANSWER: I'm not sure of the total number per case. I know I bought about 8 of them.
You can buy any number that you'd like I'm sure of that.
what kind of tool is required to adjust the spray nozzle in a rotor 6000?
Frank b on Jan 12, 2015
BEST ANSWER: A small stainless Allen screw under the top cap threaded all the way out will allow the removal of the nozel insert. With this screw you can also adjust spray. This head will screw right into the cups of older nelsons as well. No digging up and replacing whole head. Hope that helps.
I have signature 6000 sprinklers and I need to get more water into the grass in one of the 6 heads that is in that zone. Will a different nozzle help? If so which one and where are they in your dispaly?

david t on Apr 11, 2012
BEST ANSWER: The Signature 6000 comes with different size nozzles just change out to a larger size.
Bought new Signature 6000 Sprinkler head. Installed. Will not rotate. Only sprays one direction. How do I fix? Thanks.
A shopper on Jul 13, 2016
BEST ANSWER: Hello, First check to see that the collars inside are spaced apart. These are for the distance you want the head to turn. If this is ok check to see that you have enough water pressure to move the head. I had one that was leaking at the base so there was not enough water pressure coming out to rotate the head. I hope this helps.
how many in a case?
A shopper on Feb 16, 2015
BEST ANSWER: Good grief! I always bought one or two, not a case. You must be a dealer. Jacko
how to adjust the rotor head?
A shopper on Apr 28, 2014
BEST ANSWER: Remove the top (by hand, no tools required unless you use the optional screw to lock it down).

A pinwheel control is inside. Simply move the two arms to the two outer locations of the desired sweep.

The easiest and most intuitive control I have found in any rotor. One of the main reasons I have been buying these for 20 years. (They also work quite well). Have tried others and consider the sweep mechanisms on others to be complex puzzles. If you are not doing it every day (I am a home owner) you want something simple and easy like this one.
I was wondering if this is the sprinkler that attaches right to the hose individually.
Jim C on May 2, 2011
BEST ANSWER: These heads are superior to rainbird, toro ...excellent head, easy to set.
Not sure I understand your question, but they attach to a 3/4 inch male threaded pvc fitting.
does it matter which way you point the spray nozzle for a half circle on the 6000 pro 4" when installing?
A shopper on May 8, 2017
BEST ANSWER: No, it can be set to spray in any direction, and you can set it to stop at any point and it will change and spray to the other stop you set. It will turn clockwise and counter-clockwise.
Bruce P on Apr 24, 2016
BEST ANSWER: Hello, I use the signature 6000. It works great and you get different nozzle for it. I use the #5 and it works great to cover my yard and my garden. Very easy to install and to adjust the distance and the area covered. They have a 3/4" base. I'm not sure what the difference is in the 6000 to the 6503. If you are looking for a pop up sprinkler the 6000 should work for you. I hope this helps.
I recently had the Signature Pro 6000 sprinklers installed. I know how to adjust the rotation. Can the distance of be adjusted? If so, what kind of tool is needed to do it?
A shopper on May 28, 2015
BEST ANSWER: it is easy to adjust the distance simply by taking an Allen wrench and placing it in the hole in the cap on top of the sprinkler head and turning it clockwise what this does is makes the screw go in further and block some of the water coming out of this sprinkler head it will make the spray of the water spray more than instead of shooting out straight hope this helps. You can buy the adjustment tool from any supplier.
I have about 28 "old" Nelson 6000 sprinklers in my lawn (1995 vintage). All of my heads stick up after use. Is there a fix or do I need the new 6000 pro?
Is it just a simple procedure to replace?
D G on Dec 12, 2013
BEST ANSWER: I sprinkle about 5 acres worth with old hunters and have been replacing as they fail. Being stuck in the up position is usually just the beginning. Then the lawn mower will make the replacement immediate. I go ahead and replace. I like the signature product because it is so much easier to adjust. Have had only one problem in probably 2 dozen I've already replaced.
I cannot tell what or where the memory ring is....is it under the angle adjusting piece?
A shopper on Aug 28, 2011
BEST ANSWER: the rotation adjustment is under the rubber cap. It usually has a black and a white side. If the black side is up this allows for a 360 degree rotation. You will need to flip it over to the white side, snap it in place by pushing down on it with your thumb and then adjust the small wings to the radius you want. If you do not snap it in place the head will still rotate 360 degrees. Replace the cap after adjustments are made.
Is this the anap-n-rain sprinkler that attaches to a hose?
Jim C on May 2, 2011
BEST ANSWER: Attaches to underground sprinkler system.
Good morning. I have a set of Nelson ADV 6510 irrigators on a tennis court and over the years the caps have been damaged therefore mud filling up in the tops. Can I purchase new caps?

Many thanks in advance.
Brad W on Oct 3, 2018
BEST ANSWER: Hello - Nelson has been bought out by Signature, nelson 6510 is the model #6500 in signature, identical the same. The caps is model # 6090 with locking screw. I just did a complete search on the internet and most places are charging $4.98 to $5.98 each. However, google Dripdepot , they are selling them for $1.52. I am sure plus postage. Hope this helps Grant
What nozzles do I get with the 6000 rotor?
Jerry D on Aug 30, 2017
BEST ANSWER: Eight interchangeable Acu-Cover nozzles--ranging from 1.0 to 9.5 gpm
Seven optional low-angle nozzles (13 degrees) for windy areas or for throwing under trees
How do I temporarily cap this sprinkler head? Ideally it would be something like a dummy sprinkler head that acts as a cap, then I would unscrew it, and replace it with the actual head when I need it back.
Marinela B on Apr 23, 2017
BEST ANSWER: I have had to do that exact thing. I first got a piece of 3/4" PVC and cut it to length. Then I bought 2 PVC connecters to attach to each end of the pipe. One connector was a 3/4" PVC plug and the other was a 3/4" pvc female adapter. I dug around the sprinkler head to remove as much dirt, then gently unscrewed the sprinkler, occasionaly move it side to side so that dirt would not fall into the hole. I gently lifted the sprinkler out of the hole, then gently inserted the new pvc and tightened down.
