Jacobsen GK IV noise complaint experiment

Being a course on the fringe of the city of Halifax we occasionally get noise complaints . Where trying to be pro active and keeping away from certain areas on the course the best we can .
One of the noise culprits is our GK IV 3 cylinder diesel Kubota engine . The factory exhaust doesn't really deal with noise to much it is basically a short straight pipe .
So yesterday I had a little time and the go ahead to try to quite this one down .
 
 
Like I said it was an experiment so some of the pipe connections I made up from my metal bin .
 
 
I came right off the factory exhaust with my homemade 90 . the auto parts store sent over a cheap exhaust to try out . Ran out of pipe but made some thing up for the exit side so water wouldn't get in .
 
 
A small video .The phone as usually might amplify the noise but the operator was able to sneak up on me while I was using a flex 21 mowing greens this morning . Usually I can hear him coming from the previous hole .
 
 
Now that I know I can cut the noise down by at least half I'll get some custom pipes bent this winter at muffler shop . No noticeable power loss either .
 
A few more pics . Welded nuts to 3/8 rod for support bracket.
 
 
another pic of home made elbows for experiment . The 2005 on filter is when it's due for the next oil change .
 
 
Had taken some spacer sleeves off the tru turf roller spiker attachment that we don't use and welded them to homemade pipes so muffler could be clamped in place with clamps .
Has gone out twice now with no issues or power loss .

 
 
 

 


Big Culvert Project @ New Ashburn

New Culvert going in between #1 green and #2 tee this week . This is the only area that was built up when the course was constructed  to cross the river . It's the only way we can get large machinery out on the course for renovations.The old steel culvert finally collapsed to the point where it was unsafe to cross to get to # 2 tee . The rest of the course has covered bridges for river crossings .  Perfect time to tackle...very dry ... the river is down to just a creek and had to be re-routed till the job is done .Irrigation was cut and capped . There is another main line that can still feed the system for watering  .Construction  started on Monday and expect to be finished by Friday . There is a very small window to get it done in time for the coming rain .  The golfers are getting chauffeured to the next hole for their safety .
Lots of gear needed. It's a pretty big undertaking where the old culvert elevation was pretty deep .

View from the back of #1 green . The excavator is getting a pad ready for the crane . 
I'm not really that far from the hole but it is down pretty deep as you can tell by the size of the workers in center of the picture .
Service road in background.

All the new cement culverts sections are at the site and ready for placement . Seven Foot diameter pipe and each section weighing 11 tons .
Won't be much longer now most of the prep work is done . Once the contracted work is finished the crew will be tidying the area up , hooking the irrigation pipe up and reconnecting the wire for their decoder Rainbird system .
Stay tuned more pictures / and comments on the project to come from Brian Gouthro ( superintendent )

 The 5 ft. galvanized culvert which was installed in 1969 rotted out . The provincial  Dept. of the Environment decided a 7 foot concrete culvert with fish baffles had to replace it . After months of delays ( on Environments part ) we started installation on a Monday, backfilling began on Friday. The job went well and I am confident the extra prep time we spent on the site allowed a fast and efficient installation The members couldn't believe the scope of work involved. I was happy and relieved to see how crystal clear the water in the river remained during the whole operation .

Headwall to prevent the water from under cutting the culvert being placed .


They are using a 37 tonne crane to move an 11 ton 7 ft. inside diameter culvert .



We used a 450 to push the 11 tonne sections of culvert in place.


Tamping the gravel around the culvert . It will require gravel up to the spring line on both
sides .

Large area mower operator protection .

Recently I installed some medium duty mesh on the ROP ( Roll Over Protection )The sidewinder and rough units are always out on the course during play . My 5410 fairway units also received them , occasionally they will get caught by the members . The operators are always trying to look back to see where the next shot is coming from . When installing something on ROPs you have to zip tie or clamp items to it . You cannot weld or drill into them because you may weaken it possibly causing it to fail when / if needed . There are a few models that have factory threaded inserts for attaching items to them .



 
Heavy duty zip ties where the answer to installing them . Quick and easy .


 
I couldn't go right to the bottom and left a space so the bonnet can be flipped up for service . Still provided adequate protection . On the sidewinder the area from the bend down was left un zipped so the engine bonnet could be lifted up .
 
Had great feed back from the operators . They love not having to look back at play behind them . It will defiantly speed up the mowing .
