JD 7400 rear roller wear

We use one of 7400 mowers for doing tree side cart path edges . Saves a lot of hand mowing labor . The slope of the cut makes the roller ride on the cart path edge accelerating wear on roller tube . The tube was not available for purchase from the dealer so I gave the rough dimensions to Metals R Us and they were able to match it fairly close . 

Spec of tube stock I used . 

 Worn out roller tube . 

Pulling shaft out 

Cutting the new tubing at 22"

Make sure ends a squared off 

Had to bevel the inside a bit and grind a little out inside before assembling 

Piece of rod makes quick work to punch ends off old tube . watch you don't punch in center ruining the inner seal . rotate 180 degrees back and forth and side to side to force it out . 

End cap I buffed off any debris 

I just pile drive it by hand on a solid surface rotating a quarter turn every hit . 

 Reinstall shaft etc . and done . All 3 took a few hours but well worth the trouble 

HDXD easy cheap RAD Guard

Yes didn't like these guards anyway . 

Kept falling of or getting snagged and torn off . 

This is they way I found it . 

Easy repair . I took 2- 2500 spent bedknives and used bolts to attach them in mounting holes using washers to take up the bushing whole size . Then simply remove battery cables and weld a 1/2 " mesh that I had laying around the shop .

And paint . Easy to blow out or wash now . 

TCA 25900 line JD 8800/7500 fix

We have a John Deere 8800 that was here first during grow in . It has an issue that started last season with the TCA25900 line sheering off . Replaced it twice and decided to post it on Twitter to see if it has happened to some one else before . Only took a short time and Daniel L Barns  (@DannoDoes) had the answer I was looking for . Funny how you can trouble shoot and redesign things to prevent recurring problems and the fix was so easy . The problem is this machine has developed a slight flex in frame or something . ( we have 5 units with this line and this is the only one with an issue ) and is twisting the steel line back and forth ever so slightly till it snaps . It may take 6 months or 6 weeks . 

The Beast logging lots of hours for us (2149 hours )

I like them very comparable to the Toro 4300 I had at the last course . Smaller decks are great if you have lots of hilly areas.

Best way I found to get this nut off is to go in where line is and pull onto nut . 

Ratchet straps are great to pull decks away on work areas .t 

Some time you have to go to the past to fix the future . Lol anyone remember the LF 100 all hoses some 15 feet long I'm guessing. 

They are snapping directly after this nut 

New line going in 

Maybe get a long 90 here . There is enough room .It was close .

One of the old broken lines .

Easy fix . check for leaks . Also no fluid will come out of this section when changing over .
