48" will work fine.
Thank you for bringing this up, Sergeant. As I was replying to the thread, I was thinking how my 10hp 210 with the 47" deck handles thick grass just fine, even while mowing on a slope.This question is asked Often will 18HP be enough for a 48inch deck The simple answer is Yes 40 Years ago 10HP single cylinders Lawn & Garden Tractors were Handling 48inch decks. Heck that 18Hp could even handle a 54inch deck without a problem If You want to spend Less Than a X300 as some have suggested I would Not Go Below a D160 Or D170 Because they at least Have the same Transmission Meaning a K46 The t40J used In the Models Below the D160 Is Good for a 1/2acres or Less for Mowing and occasional snow removal The T40J seems to be a transmission that can Be easily Taxed or develop Problems faster than Most Tuff-torq Transmissions. The Nice thing about the X300 series You will have a 4year warranty over a 2 year Warranty you get with the D series. The X300 with a 48inch deck Should Handle Your Yard Just Fine. If Your think about another Model because You don't Think the X300 is enough than I suggest a X320 as Other Have stated Basically The X320 Has a Better Trans Than the X300 Model The X320 has a few More Horses, Bigger rear Tires and a K58 Transmission which is still a sealed Trans Like the K46 which means You Have to remove The trans from the Tractor to service It. The Only serviceable transmissions In the X300 Line are the X310 & X360 which Have Hydraulic Lift & Power steering. But as I said the X300 with a 48inch deck Should Be Just Fine:thThumbsU
I used to have a 50" GT. When I set out to replace with a new tractor I had choice of 48 or 54" deck. I mow an acre but I have a 600' stretch along my drive that is on an angle. The 50" was always digging into the ground along this stretch and I was afraid it or the tractor was going to get damaged. I settled on the 48" which is the right size for this area. If I had gotten the 54" I would have had to revert to push mowing of this long stretch. This would take a lot more time to mow manually than what I would have saved elsewhere with the 54". Sometimes bigger is not always better. So yes, look at the obstacles in your yard before deciding to upsize.One thing you might want to consider here is where your tractor goes. Measure any gates you might have and make sure an 48 inch will fit. And then then measure any tight spots you might have like the distance between a tree and a retaining wall, or the distance between two trees. Maybe you have a tight walkway you need to travel to get from your garage to your lawn. Maybe you will need to trailer you tractor for whatever reason, the 42 will fit on a 4X8 with sides, the 48 won't. Also take into consideration the extra width with a bagger attachment. Will a 48 fit into your shed or garage? If the 48 will fit where ever you go, then go for it. I chose the 42 so I did not have to re-size my gates.
Model 47 and Model 48 decks where Both 46inch width of Cut Though But You could Buy a 8Hp 200 or 208 with a Model 47 deck or even a 110 Fender deck Model with a Model 47 deck:thThumbsUThank you for bringing this up, Sergeant.
