It is definitely cool to see fellow irrigators posting videos of Nelson Big Guns operating in the field. Thanks so much for sharing. We are proud of our built in the USA products.😀

[@photocontrol]

These are awesome guns! Thank you for stopping by and commenting!

[@NelsonBigGunP200Fan]

I've loved nelson big guns since I was a kid. Especially your 200 fast reverse guns. I've seen some get some awesome range. Be back in the field and get the field across the street. Definitely cool! I have a 100 150 and 200 gun from your fast reverse line. All except the 200 work. The 200 is missing parts and they're hard to find

[@randyvanheusden732]

I like the slow reverse. I also like that it has more weight consequently having a little faster arm movement and more frequent strikes. It operates like new, amazing.

[@beebeesfuntasticadventures6110]

It looks durable and can last a very long time, a real time saver, nice looking product.

[@photocontrol]

Yes these are very durable units and low maintenance. They can water a large area for sure!

These always have an iconic sound when operating and switching directions. The reverse mechanism has such a distinct sound when activated. I can always tell a nelson gun when I hear it

[@DriveShaftDrew]

yup thats a big gun forsure 66gpm wow awesome thumbs up shared

[@photocontrol]

Thanks Drew!! Yes these can sure shoot a lot of water!

[@NelsonBigGunP200Fan]

speaking of big guns. I just posted a video of me trying to run my PC100 (non NV version) with a .60" nozzle from a big trashcan full of water. I got about 1:11 run time until my pump stopped pumping due to the can emptying so fast. I kid you not it was almost full and i turned m,y pump on, waited for the gun to get pressure and move and i went to look in the trash can to see how much was left it was less than half. That 2" hose moves the gallons.. anyway its on my channel and actually doing this moved the counterweight on the arm unlike when i was at the pond, im not sure whats different except maybe that the suction hose was about 3-4 feet off the ground inside the can (tall can). maybe that had something to do with it, but as far as i know the more it has to work to pump the water the less performance you get. which is why i need to get the other end on my 10 ft suction hose and try that to see if i get some better performance.

[@photocontrol]

Yes the pumps can move a lot of water quickly! That could be the case that the counter weight was moving due to the water in the trash can being "above ground" rather than the pump having to pull water up a few feet below from the pond.

[@NelsonBigGunP200Fan]

The dealer finished my p150 rebuild. It wasn't cheap but it's in working condition. Now I need to find a smaller ring nozzle for it or get the assembly off and switch it out for a .70" taper bore.

[@rayhayden]

Another LIKE for your video! I am impressed with how this is so sturdy, and would make very short work of wetting down a field! Forgot to mention, love the rainbow effect nearer the end (5:47-ish)!

[@photocontrol]

The sled base works very well and will not move much considering the force of the water. These sprinklers will water a section of the field in about 20 minutes. Thank you for another like!

[@JohnCRV]

Nice model. Good information. You take care.👍

[@photocontrol]

Thank you John! You take care as well, have a great weekend!

[@NelsonBigGunP200Fan]

There is a video of a guy with a SR150 that was short stroking due to bad arm bearings. He replaced the bearings but now it hits the stream so hard it pushes the arm back so far that it hits the bottom of the guns barrel. We tried (me and ian) telling him to adjust his counterweight and drive spoon but he can't figure it out. He will eventually be replacing bearings and other parts again unfourtanetly because of it hitting the stream so hard and pushing the arm back so far. He should probably invest in a SR200 as that's meant for high volumes and won't have that effect on the drive arm

[@photocontrol]

Hopefully the guy figures it out before having to overhaul it again.

[@beebeesfuntasticadventures6110]

A real time saver, nice.

[@photocontrol]

Thank you! Yes these save a lot of time!

[@NelsonBigGunP200Fan]

Still looking for any of the old FR guns. Like a p100,150,and 200. That p150 is still on ebay for 1000$ or best offer, I offered 430$ and he declined. My friend said I shouldn't pay any more than that because it could need rebuilt. Arm bearings, reverse mech bearings and linkage, brake, etc. The guy says it works fine but I think everyone's definition of "fine" is different. I'd pay a little more but don't want to pay a arm and a leg for rebuild

[@photocontrol]

I wouldn't mind a P100 or P150. $1000.00 is pretty steep, especially when factoring in the lower value of the Canadian Dollar, then it's about $1260.00 with the current rate of exchange, plus import taxes and shipping. Yes true, if there's a good chance it needs to be rebuilt, then your offer is reasonable. I agree, everyone's definition of fine is different lol.

[@Shimizoo32]

Wonderful share👍✨

[@photocontrol]

Thank you very much!!

[@NelsonBigGunP200Fan]

Someone on ebay has a SR100 for 99 cents starting bid or best offer. Thought of offering 100 to see what happens. Looks all there too

[@photocontrol]

Oh wow, yeah that might be worth a try if they accept it. I'll have to take a look.

[@photocontrol]

It looks good, it does appear to be complete, even has a ring nozzle with the set of different size rings included.

[@NelsonBigGunP200Fan]

The dealer called and said it'd be 400ish to rebuild my p150 I told them go ahead. I'll definitely make a video once I get it back especially the brake settings I'm going to show the difference with it set and with it loose. Did you know you can remove springs from your base to adjust the brake on the SR guns ? I watched a video on nelsons page about troubleshooting a end gun that won't rotate and they said for lower psi try removing a few springs from the base and that'll loosen it up a bit making it move a little faster

[@photocontrol]

That will be a steep cost to rebuild, but you'll have a good working unit. No I was unaware that you can take out the springs for adjustment. Makes sense for better operation with lower pressures.

[@josevaquedano788]

l bought few used in Ebay and might will need reconstruction but 400 ?? I will order the for Lowe unit rebuilt l will do my self

[@mbulahenimunyai594]

@photocontrol Could you please share the details of the setup, the blue part on which the big gun is mounted on? I'm getting the SR 150. I'm new to this type of system and need some assistance on how to set it up. Thanks

[@photocontrol]

Hi, that's great you are getting an SR150. I welded up the mounting base myself based on the model shown in the link here. www.atsirrigation.com/products/agricultural-sprinklers/sprinkler-carts-and-stands/ Looks like the company closed. Theirs has a solid riser but I installed a 2" pipe with a threaded tee and can change the height of the riser if needed, my angle braces are adjustable as well will a U bolt to support the riser pipe and allow removal rather than being permanently welded. I use cam lock fittings to connect to the stand and have it set up where I can use 2" hose or lengths of 2" aluminum irrigation pipe. I believe the SR150 has a 3" inlet so your setup will have to allow for the larger size pipe connection.

[@NelsonBigGunP200Fan]

​@photocontrol I want a stand like yours. With it being easier to set up and being able to tale extra weight for bigger guns as well is a big plus for me especially with my stand being more susceptible to flipping due to the extra pressure of 2 pumps. I could use sandbags or bricks or concrete blocks to weight it down. Plus I don't have to set it in the ground either just pull it across the grass. Would be easier to set up and I'd put some camlock adapters on it as well for quick and easy connection to a hose and I could use adapters too for easy switching of sprinkler heads or guns.

[@NelsonBigGunP200Fan]

Also does your f100 have a ring or taper nozzle ? If it's ring, it's easier to change. You can just take the cap off to change the nozzle, which is a ring. It's basically a stainless steel washer

[@photocontrol]

It has a taper nozzle, it's a .70" which should work pretty good with my pump, I will order a .55" nozzle to try on it.

[@NelsonBigGunP200Fan]

@@photocontrol a .55 will give you much more pressure and less volume. It's strange how a .86" ring works better on my p150 than a .80" taper on my pc100

[@photocontrol]

@@NelsonBigGunP200Fan That's interesting about the ring nozzle! I thought I would order a .55" as I don't have that size nozzle yet.

[@NelsonBigGunP200Fan]

Went and picked up a 25A RB, a 14600 Plastic RB impact, and another F44A and a .086" ring for my p150. Got the cap off and the ring changed to a .086" and got neversieze on the cap threads.

[@photocontrol]

Nice!! The nozzle on my F100 is on there good, I tried heat and PB Blaster but no go... I'll keep soaking it...I have a bearing and seals to change on it so once I take the drive arm off I can set it in the vice and get more leverage.

[@NelsonBigGunP200Fan]

What is the price of this rain gun Does it operate on 10hp motor Do u sell in Andhra Pradesh india

[@photocontrol]

The price of this rain gun is approximately $900.00 USD. Yes it will operate with a 10hp pump motor. I do not sell these, I just have for my own use.

[@NelsonBigGunP200Fan]

Very nice SR100. That's on my list of stuff I want. Your pump runs that very nicely. Did you get that off ebay ? My wish list for big guns is a p100,p150,and p200. And a SR100,75 AND 150. Also I want a rainbird 105c and one of those bauer mirror image guns that are like a p200 but are backwards. They go reverse for the forward cycle and then fast forward for reverse. Very rare to find.

[@NelsonBigGunP200Fan]

The p100 150 all have their reverse deflector on the bottom of the barrel and are fully adjustable from drive arm to brake force to alieve some stress associated with the fast reverse cycle

[@photocontrol]

Thanks! Yes I got it from ebay. That is a nice wish list you have! I will be eventually getting a Rain Bird 103DL which seems pretty rare these days, that will be my first fast reverse model. I believe the 105C is similar. Sounds interesting, I never heard of the Bauer mirror image guns before.

[@NelsonBigGunP200Fan]

@@photocontrol is that a flange mount gun ? And if you figure out how to adjust the brake and reverse lever let me know so I know how to do it on my 205G
