I also have 2 John Deeres. One is a 1987 318 with all attachments plus a custom loader I had made for it. I replaced one engine myself because I let it run low in oil and broke a rod. The other is a late model JD X465 with blower and 60" mower. I also had a custom adapter made for this tractor so some of the 318's equipment will mount to the bigger one as well. These are not riding mowers, they are garden tractors with a strong frame, heavy duty suspenshions, can take a trailor hitch, has power take off front and rear, and larger tires. I used the 318 when I built my present house to backfill, level, plant grass, sod the steep areas, haul timber, and landscape my yard. The 28 year old still has the original back tires on it because I always kept chains on them for traction and airation of the soil. With the larger tractor it takes me about 4 hours to cut the grass if I do the orchard also. My next door neighbor, on the other hand, has two Murrays ( they have to buy a new one every year) and it takes them about 3 days to cut their lawn, leaving it looking like a hay field when they are done. Last year they bought a Cub Cadet and now it only takes 2 of them 2 days to cut it with the same results. 3/4s of an acre is right on the edge of being to large for a riding mower and needing something larger. They are more expensive, but well worth it !! Look for a used one with low hours. My first one was bought from someone living out in the country and moving into the city because of a job transfer. The last one, the X465 tractor, mower deck, snowblower, lawn roller, and trailer (All brand new,never used) was purchased from a woman whose husband had bought it in November and died before the first snow fall. I gave her a thousand dollers more than she was asking. She just wanted it out of her sight. Only thing I would add next time, would be four wheel drive. That has been my light on riding mowers. They are good if you have a smaller level yard. Jim S
