John Deere
On John Deere - there is a rib that runs across the deck that is approx. 1" tall and 2-2.5" back from the deck edge. On smaller decks, like the 636M, you will need to raise our unit 1" and mount 'The Green Guard' so that it straddles the rib. On larger decks, you can mount behind the rib and use spacers to extend the swing arm out to the deck edge.
Here's the models we've been able to verify 'The Green Guard' will fit on:
1.) John Deere 636M Stander - [HD] or 'SLIM'. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck. Drill 2 holes, and bolt down, so that 'The Green Guard' straddles the rib. (Does not work with no-drill kit. Must be bolted on.)
2.) JD 652E & 652R Stander - 'SLIM [HD]' or 'SLIM'. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit.)
3.) JD 648R, 652R, and 661R Stander - [HD] or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit - except unsure on 48.)
4.) JD Z915E ZTrak (48", 52", & 60" Deck) - [HD] or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit, but 48" and 54" decks require 'SLIM [HD]' to fit.)
5.) JD Z930M ZTrak (60" Deck) - [HD] or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit)
6.) JD Z950M ZTrak (60" & 72" Deck) - [HD] or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit)
7.) JD Z960M ZTrak (60" & 72" Deck) - [HD] or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit)
8.) JD Z950R ZTrak (60" & 72" Deck) - [HD] or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib and use spacers to extend swing arm to edge of deck. (Does work with no-drill kit)
9.) JD W36R Walk-Behind - 'SLIM [HD]' or 'SLIM'. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Or, mount behind the rib, and forward of the handhold loop. (Does not work with [HD] no-drill kit. Must be bolted on.)
10.) JD W48M Walk-Behind - 'SLIM [HD]' or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. Line up the notch-out in 'The Green Guard' base with the front vertical riser of the handhold loop, to allow it to move towards the deck edge enough that it straddles the rib. (Does not work with no-drill kit. Must be bolted on.)
11.) JD W52R Walk-Behind - 'SLIM [HD]' or Original. Use spacers to raise unit 1" to get 'The Green Guard' base up above the rib that runs across the top of the deck, and straddle the rib. (Does not work with no-drill kit. Must be bolted on.)
12.) JD WH52A Walk-Behind - 'SLIM [HD]' or Original. Mount behind the bar that runs across the top of the deck. Use spacers to raise unit 1" to get 'The Green Guard' swing arm high enough to reach over the bar. Use spacers to extend swing arm to edge of deck. (Does not work with no-drill kit. Must be bolted on.)
