Radar:
I bought my PT 1945 primarily as a slope mower, after too many sliding rides down hills on a JD 950 with 6 ft brush hog. We never rolled it or its Farmall 300 predecessor, but I, particularly, got too old for that level of excitement.
MossRoad and BobSkurka have touched most bases. I agree with Bob that a rear mower is fine for open areas, and add thatdoesn't put you in the chaff cloud that front mowers do. I personally prefer the front mower, however, for visibility and maneuverability. I think the front hydraulic posthole auger is far better that a PTO mounted one. You can put weight on the rear ones, or a downpressure kit, I understand, but generally they count only on the auger, which sometimes just polishes the ground. Positioning is far easier with the PT. My record is 78 holes in 80 minutes, which I simply couldn't have done with a 3 point.
For loader work, the conventional tractor may have an edge. It will lift higher.
For implement changes, the Power Trac wins hands down.
For dealer support, the New Holland has no competition at PT. There aren't any PT Dealers. I've gotten good support from Power Trac, but I don't join MossRoad in letting them completely off the hook for their secrecy about third party parts suppliers. More importantly, they refused even to talk to John Coxon - Sedgewood - during rebuild of his machine after a fire, because they were afraid his insurance company might claim against them.
I really like the machines, and have had no trouble dealing with Power Trac, but they are a quirky group - as their owners also tend to be. /forums/images/graemlins/grin.gif
Asolution. Buy both machines and post comparison tests on TBN. We'll all be happy to propose test protocols. /forums/images/graemlins/cool.gif
