ne iowa | Son has found a decent running 4520 for blowing snow and asked me if his 148 loader would fit? I said I think so (narrow frame?). I think they had jerky pto, anything else..... |
|
| |
|
Lincoln County. NC | I'm gonna say I'm pretty certain it won't fit. And without question with one false move a 4520 would turn a 148 loader into a second hood ornament if it did happen to fit. |

|
Saronville NE | Neighbor used to have a 4620 with a 158 ldr, so it should work. Make good loader tractors cause of heavy frontend, dont break the frontend up all the time moving bales and such. |
|
| |
|
Lincoln County. NC | I was thinking the 168 was for the large frame tractors, but I'll defer on this. Surely if a 158 fits a 4620 then a 148 will fit a 4520. |
|

|
ne iowa | He just has 10 cows and needs to feed a few bales over rough ground. I think 148 will fit until someone says otherwise. thanks |
|

|
Nance County, Ne | A 4520 is the same size frame as a 4320 I believe so then the 148 should work. |
|
| |
|
| acording to to my owners manual for 148 and 158 loaders it wont work 4320 is largest 20 series the 148 fits 4520 and 4620 need the 158 loader i had the same idea about a week ago |
|
| |
|
ne iowa | can the 148 be modified to fit 4520? |

| The 158 and 148 are the same width, the 158 is longer. More reach. 15" longer booms. 33" more ground clearance with the bucket dumped. The 158 is 420 pounds heavier than the 148 and has 1100 pounds more breakway and 700 pounds more lift capacity. 1760 vs 1340 (72" vs 60" bucket), 5800 vs 4700, and 3800 vs 3100. The specifications page clearly says: "Mount 148 Loader on John Deere 2520, 3020, 4000, 4020, 4020, 4230, 4320, and 4430 Tractors." "Mount 158 loader on John Deere 4000, 4020, 4230, 4430, 4520, 4620, and 4630 Tractors." The fact either fits a 4020 says width is not the problem but length of tractor probably is a problem along with the 158 is heavier enough to endanger the stock 4020 and smaller tractor front end.
I have two versions of the manual, that I could be persuaded to sell.

| I would think that frame of the 4520 is longer and the 148 booms are shorter, the cross pipe on the loader boom might hit the front of the hood |
|

Brazilton KS | It will physically fit, the width of the frame is the same on everything from a 2510 to a 4630 (and up to 4960, but there are body clearance issues on the 4640 and up which require the 168 for bodywork clearance) you just have to mount the loader relative to the front of the tractor.
The problem is that the tractor will turn the 148 into a pretzel if you use even a portion of it's tractive ability. |

|
south central nebraska | I have never seen a 148 mounted on a 4520, the frame width is not the concern, but like Thomas says,the cross pipe hitting the hood. I would certainly do some measuring from the frame to the top of the hood and compare to a 4320 or a 4020 |
|
| |
|
Brazilton KS | Loader brakets wrap around the front of the nose, not the back...the "extra" length will end up between the loader masts and the rear axle, not between the nose and the masts. |
|
| |
|
Brazilton KS | Does a 148 have a brace over the hood? We have a swartz loader that does, but I thought that was just an aftermarket shortline will-fit thing. I didn't remember 148 or 158 having anything above the hood. |
|
| |
|
south central nebraska | no they don't have anything over the hood, but wasn't sure about the distance between the masts and the cross tube either

This is exactly what my thinking was, top to bottom. Except I was thinking the 4520/4620 had significantly wider hood/fuel tank than the frame rail width. Apparently not. Having owned a 4010 with a 148 and a 4020 with a 158, I'm having a hard time figuring how one would physically fit a given tractor and the other not.
I don't have the advantage of a manual in front of me, however. |

|
| Thats true, I didn't consider that when I posted. |
|

Brazilton KS | Manual is going to say it won't work. I don't know for sure about the width of the sheetmetal on a 4520-4620 I know a 4630 is no wider then anything else. I am almost positive neighbors bolted their 158 onto their 148 brackets when they put the 158 on their 3010, so I'm thinking there is no width issue. The 158 is listed to fit the 4520 |

West Union, IOWA FLOLO Farm 52175 | According to parts....the main difference on all is the length of the side rails (148-168). And 45-46s have more bolts.....
Hope the link works, other wise it'll just take you to parts..

Well differing side frame lengths would explain it. I guess I never noticed the difference between the mounts on my own 148 and 158 unless they happened to be 148 mounts that came with the used 158 when I bought it. Of course my auction was 20 years ago next month.................... Edited by RickB 2/4/2012 19:05

| What Gerald said. 148 can stack bales 2 high. 158 has longer reach and can stack 3 high. That's the practical difference. 148 should be easier on front end than 158 because it keeps weight closer to front of tractor. |
|
| |
|
| We used to have a 148 on a 4630. It fit fine but didn't have much lift. |
|
| |
|
| 4520 and 4620 were same frame. 4320 is slighly smaller frame and has light front end. A 148 as it came from the factory will not fit a 4520. |

ne iowa | thanks everyone. go cyclones and good night! |
|
| |
|
| I have a nice 158 thatcame on tractor I bought, would sell and it's in nice shape. |
|
| |
|
Eastern Montana | I had 4520 and have seen 158 on one. It's pretty tight clearance between the sheet metal and the loader arms. |
|
| |
|
Tennille, GA | Gerald J do you still have an extra manual for a 148 loader?
|
|
| |
|
| Binboy, do you still have the 158 for sale? What width bucket? Location?
