I have a 1720 and have researched this extensively...
The New Holland alternative is the 7308 or newly numbered 110TL...
The Bush Hog equivalent will be the 2246QT or newly numbered 2247QT...
The Woods equivalent will be the LC96...
The Rhino equivalent will be the 2408...
The Westendorf will be the TA111...
All of these loaders lift 96" to 100" total height...
The New Holland will probably be higher in price from my previous research...
Keep in mind that the lift capacities for all of these units are a little different in that they use a different psi in the ratings. The 1720 only goes up to 2150 psi max...
Also keep in mind that the 1720 has a front axle rating of 930#...
The lift capacity at the pins will be higher than the lift capacity at the bucket edge...
The New Holland is rated @ 875# max cap. at the pins at max height...
That number will be reduced by approximately 30% @ the bucket edge...
