Just as a side note for reference. The 750 lbs atv/mower lift is only rated for 500 lbs as a mower lift.
Understood. But considering the lift point of both the ATVs and mowers I would think it much closer to 750. I have used it lifting the front ends of most commercial ZTRs here especially the JD Z900 series with the Seven Iron decks. Much better rating than the low end rider lift that HFT sells. Just as I said the ATV H needs to be removed if use it to lift many of the Riders and ZTRs. It just interferes with accessing The PTO area of riders. Also can prevent some mowers from fully seating in the lift arm cradles.
The only Z900 Series I haven't lifted is the one with the 72" deck and that is only because the customer brought that mower in without the deck. He had to remove the deck so he could load it on his trailer. Boy they to wheelies without the deck.
One other note when using these lifts is the drive must be in neutral and the brakes released or the wheels may become un-seated from the cradles. Also make sure the safety locks are active just in case a jack failure.
The jack really could use some spring loaded steel rollers if using as an ATV lift so you can push it under the ATV middle section. Otherwise it works fine as a mower lift lifting the front or rear of the ATVs.
