Following the previous threads from this week re my test of a J.D Side Discharge 997, against my problematic 997 Rear Discharge. Test 1 failed as no predelivery was done, engine was only revving at 2700rpm not 3000...this machine needs full power to properly work the 7 Iron. the story continues... Well, got bloody mechanic to put revs up to 3000rpm, he had em on 2700, we had to go to dealership owner to make this happen! anyway, we tested the RD against the SD this arvo in 3 ft tall grass, short grass, lawn grass etc, we made chaff everywhere on purpose to see if the rear screen would clog and cause overheating like my RD 997 does, the RD just was hopeless in comparison! The SD did not have clogging issues or heating issues! The SD was a power house, bloody awesome! My new mower is a 997 SD, I'm so impressed with it, never had that feeling with the other. Ultra clean cut, can mow jungles and nice stuff, awesome! And most importantly, no downtime from overheating!! yeeehaaa! I'm very happy, happiest I've been with a machine in 6 months! The SD deck is heaps better than the toro turbo force too, amazingly, the j.d deck is able to feed more volume in, excellent on stringers too! (never thought I'd say that!) I just wanted to tell yas! I can stop annoying the crap outa deere and the deere lovers now! lol. maybe ha ha ha! So far from my test I can recommend the J.D Side Discharge 60'' deck ('05 model) 997 model. BTW, The dealership owner made this exchange happen, not the salesman, not J.D, so I'm not thanking or praising Deere, but I am greatful to my dealer ship owner.
