| An R52 is coming up for sale close buy and I'm going to go look at it this weekend. It's a 97 and got a Cummins in it. I'm currently running an 82 L2 with skip tooth cylinder bars. I'm just wondering how the two compare in capacity. Will I be gaining anything. I was really looking for a 62 but this one is close by. Any advice is appreciated. Thanks. Derek |

Not a bad machine but I think you would be happier with a 62. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

| I don't think you would be happy with a 52...L-2 will out do a 52...I'd wait and find a 62 if your dead set on staying silver |

| I've never been around a rotar machine. Does anyone have any advice as to what to look for as to wear on the rotar parts. Rasp bars and concave/cage measurements. Thanks |

Check rotor bars and helical bars for wear, when these are worn crop doesn't move through as well. Just check all auger flight and sprokets for wear. As with any used piece of equipment, look over good before a purchase. Its a simple combine to work on and would have the same capacity as the L2 if everthing is upkept if not a little more. 98 models and newer models have more updates like the 62 and 72 such as larger clean grain elevator and (i think) they had the heavier unloader swivel as an option. Need to check accelerator rolls for wear since they help speed the grain up for pre cleaning before it hits the shoe. ------------- 8070FWA,7080 BlackBelly, 7045,2 200s,D19,D17,G, WD,45,UC,7 AC mowers and lots more!

| One other major wear point is the clean grain elevator boot, especially on the side the auger enters from the grain pan. If it has the newer larger clean grain elevator, then it will be the same size as what is on a R60 (the smaller elevator is the same as what's on the R50, M, and L). My R50's biggest choke point is trying to get grain out of the pan and into the hopper, but the local dealer also took half the threshing and separator bars out of the rotor (left the rows with the reverse bars in). By taking half the bars out it allows the crop to "fluff" more and release kernels trapped in the trash. Also with the fewer rotor bars it takes less horsepower to spin the rotor and you spin it a little faster to thresh the same crop allowing you to have more rotor capacity and engine power in reserve. |

| L2 will eat a R52 alive. Friend traded M2 for a 52 and was disappointed. MACK |

I've heard of hyperized R52 pretty much keeping up with stock R62. Never witnessed it just heard about it. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

| The 1997 R-52 has the long cleaning shoe and larger elevator and will make any model "L" series look stupid in corn and especially on any side slopes. |

We had a 52 before trading for a 62. was a good machine other than being underpowed. dont recall how it did in corn we dont grow much out here but spent many hours harvesting wheat and soybeans. you did not work after dark when things started to get tough. the 62 wasnt bothered nearly as much by green stems or weeds either. ------------- Me -C,U,UC,WC,WD45,190XT,TL-12,145T,HD6G,HD16,HD20 Dad- WD, D17D, D19D, RT100A, 7020, 7080,7580, 2-8550's, 2-S77, HD15 |

ours had the duetz inline 6 so it was an early one. never gave trouble, just not enough power it seemed like. still running R62 and R72 with V8 duetz and get along fine

Was the 52 hyperized CAL? Supposedly a hyperized 52 will take a whole lot less horse power. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Every person sets their combine up differently. I have had a 1992 R52 since 1994. I have become very acquainted with her. We also have an L3. The R52 will run away from the L3 when both have a 20' head on in beans, oats and wheet. When it comes to corn, the L3 is just a pain as it is always in the way of the R52. My R52 in 240Bu/acre corn with a 830 head on it will run 4.3mph. The L3 can not come close in the grain sample cleanness nor in minimizing damage. When we got the R52 I thought it was a joke. There are very few people I have found that understand how they work and how to adjust them. And yes I have the small shoe and the Deutz engine. It is very fuel efficient in comparison to the Cummins, and especially compared to the L3.

Doubtful, this would have been 93-97ish? Pretty sure this was a demo unit that my dad and uncle picked up as they knew the salesman at the dealer pretty well. we were cutting about 1500 acres of wheat a year and just needed a bigger machine. Leased a 62 for the season and then traded the 52 on it and kept it. I was in high school at the time so wouldnt have noticed anyway

Post your opinions of the machine if you get it. We have 2 L3's, one for corn and one for beans and looking to up grade. Even this post gives completly different comparisons between the R52 and L2,L3. I had kinda thought I would need to go to the R62 to be happy but want to stay with a 630 corn head and a grain table not more than 25'. If a 52 with a Cummins ( dad will not even consider an air cooled duetz? ) will out preform an L3, I would be satisfied but don't want to take a step back. I've been told you cant put enough corn into an R62 with a 630 to make it efficient. Combines are so freakin expensive, I don't want to make a mistake on what to look for.

| Leon, I'm in the same position. I really don't want to step backwards. But if I can get a newer nicer machine with the same capacity I would be happy. I have a 2 year old that needs a buddy seat. |

| There have been MANY changes and improvements to the feeding system to help with its capacity. By the 1997 model year, the throat worked much better than a 92 model and there are things in the after-market world to drop the rear floor under the drum for even more appetite. This isn't needed for corn but sure helps in green-stemmed soybeans. |

| I ran several R52's from1996 to 2013 on 1900 acres and I think the enclosed rotor was one of the best improvements for soybeans. We ran 20 foot heads and normally ran 4-4.5 mph. |

We had both an R50, and a R70 with the air cooled Deutz. Also had a 9150, and a 9190, 9650, and 9690. Keep them clean, and they are good engines. Also had a dozen deutz irrigation engines, just never had any problems. The R50 is a nice 6/30 machine, that is what we started with, toward the end it had an 8/30 head, and while it will handle it, it is a bit much. The neighbor, had an R62 with a 6/30 head, but that was not enough head for that combine for it to be efficient. I don't have any experience with the R52, but the guys that I knew that had them, liked them.

You really want to study the condition of the cage. Rocks cab beat the heck out of the cage. Our R52 was air cooled and it was nightmare the R62 is a Cummins and the motor cost a lot less to maintain. I don't buy the keep it clean and you will be fine. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

If I remember correctly, the R50 had ~2300 hours, and the R70 had ~2500 hours, with normal maintenance. Plus the engines were blown out twice a day in beans, and once a day in corn. The irrigation engines, were blown out at each oil change. With normal maintenance, each one made it over a 9000 hours, and a couple had over 12,000 hours, before being retired.

A 97 r62 is light years ahead of an l2 ,should outrun the l2 all day.and alot more simpler and way better cab.listen to the doc.

You will be fine with a 6 row on a R62. We still run a 6 row on our R66 and get along just fine. ------------- Making a living farming with and working on Allis Equipment |

Big al. Every Duetz motor in the neighborhood that seen any use to speak of was apart frequently. Duetz dealer 3/4 from my house so plenty around at one time none that seen much use are still running. Next crossroad over one DX is dead in a pasture 1/8 down the road a dead one in the barn. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

| 40 % of all water cooled engine problems are related to water cooling...rads, hoses, pumps, waterjackets, cavitation, leaking. Deutz eliminated all that. Blow the fins out daily just like a rad should be, and one of the best engines ever built, from 2 to 16 cylinders. The V8"s in the combines pull like crazy, very fuel efficent. Wouldnt hesitate to have one. JMHO, Trev. |

All I can speak of is my experience with Deutz air cooled diesel engines, and that experience has been positive.

Your experience is 180 degrees opposite ours. Only motor we stocked major parts for. If we made 2 harvests without losing a jug it was a miracle. Besides who builds a cold blooded motor without a block heater? Really loved sticking a salamander heater in the engine compartment. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |
